• Collection of the dynamic query

  Hi All-

  I'm trying to get the value of the collection through the dynamic query but I am facing some problem please let me know that I hurt.

  Created a function like below to run the dynamic query to select statement

  create or replace FUNCTION rfunGetColumnValue (
                ColumnName VARCHAR2,
                TableName  VARCHAR2,
                DefaultValue OUT VARCHAR2,
                Criteria VARCHAR2)
         RETURN VARCHAR2
  IS
         ReturnValue VARCHAR2 (32767 byte) ;
         Stmt        VARCHAR2 (32767 byte) ;
  BEGIN
         stmt := 'begin        
  select '|| ColumnName || ' into  :1  from table(:2) ' ||NVL
         ( Criteria, ' ') ||
         '       
  Fetch First Row only ;        
  EXCEPTION                                   
  WHEN OTHERS THEN                                          
  :2 := SQLERRM;
  end;'
         ;
         dbms_output.put_line (stmt) ;
         EXECUTE IMMEDIATE stmt USING OUT ReturnValue, OUT DefaultValue;
         --select Valueinto into Returnvalue from dual;
         RETURN ReturnValue;
  END;
  

  Now, I created a folder in the Package

  As I've suggested before:

  To get the name of the table the column

  and as others have:

  Type global temporary Tables vs. table

  If you give more context, more information about the bigger picture, more information about what you're trying to do and why you're going down the road you go down, you can return more useful information. But you seem reluctant to do.

  For the moment, your recent posts seem to just raise the same type of question - why are you doing this?

  The normal way to return data to a client is a refcursor.

  It is the most effective way.

  Not through collections that you seem to be put on the must-do approach.

• Create a temporary table using EXECUTE IMMEDIATE

  Hello

  I need to create a report more complex which must have three different queries. I use a determined IF clause that the query that uses the report, according to the parameters.

  I want to write the output to a csv file, so I created a PROCEDURE.

  The first package of the procedure has the three SQL and the IF clause in order to determine the query that the report uses and stores the query code in a variable (v_sql), which is passed to the PROCEDURE that needs to write to the output of the report.

  I tried to create a table with data from the request in order to make a LOOP and exit, something like this:

  WRITE_FILE (errBUFF of the PROCEDURE	OUT VARCHAR2,
  	retCODE	OUT VARCHAR2,
  	v_sql	IN VARCHAR2)

  IS

  Contor

  NUMBER;

  BEGIN

  	EXECUTE IMMEDIATE v_sql;
  	SLIDE G
  	IS
  	Select * from XXROR_REG_MF_TBL;
  	--
  	-initialization
  	--
  	retCode: = 0;
  	errBUFF: = NULL;
  	Contor: = 0;

  	--
  	-cursor
  	--

  	FOR X IN G
  	LOOP
  	APPS. FND_FILE.
  	PUT_LINE)
  	APPS. FND_FILE. OUTPUT,
  	....)

  I should mention that v_sql is something like:

  CREATE GLOBAL TEMPORARY TABLE ACEs (SELECT * of the double);

  I can't really do that, so I was wondering if you have any suggestions

  Thank you

  Hello

  I don't think you need a table at all. You can set the cursor based on the SQL passed as parameter

• The use of bind variables in dynamic query created for Ref Cursor

  Hello
  
  I'm in a situation where there is a Ref cursor to which the query is built execution based on a loop. This is why the number of links would be known until the program runs.
  The application is currently using literals instead of bind variables.
  
  code snippet of the above is
  strSql: = "select * from emp where 1 = 1 and ().
  
  loop cursor1
  If cond is true then
  strSql = strSql | "ename = ' |" Cursor1.ColumnName;
  end loop;
  
  Open cursor2 for strSql;
  
  How to use links in the example above.

  Here is the code I have my trying to change literal-based link to the base.

  What do you mean by "based bind?

  who, what, how determines the values to be 'bound '?

  He's referring to the coding style. He is currently using concatenated literal, and the goal is to change it to use the bindings.

  If I understand this it is known as method 4 dynamic SQL and requires DBMS_SQL. There are examples autour but they vary according to the type of statement being generated - SELECT statements require column lists to be parsed, unlike the INSERT/UPDATE/DELETE.

  This came up recently on my current project and I hit a demo. Here a table of names and values accepted procedure and had to build these in a single WHERE clause along the lines of

  AND t_names(i) = t_values(i)
  

  for an undetermined number of elements in the array. For this demonstration, I used a table that we called "attribute" (don't ask) which has columns including 'attribute_id' and 'name', and I need to build a query along the lines of

  select description from attribute where attribute_id = :b1 and name = :b2
  

  by the way '1012' and 'ISIN' respectively. (I use a table better and after a CREATE statement for her but I have to rush right now, sorry).

  declare
     k_sql_base        constant varchar2(500) := 'select description from attribute';
  
     t_names           constant varchar2_t := varchar2_t('attribute_id',  'name');
     t_values          constant varchar2_t := varchar2_t('1012',          'ISIN');
  
     l_sql             varchar2(500) := k_sql_base;
     l_rows_fetched    integer := 0;
     l_value           varchar2(4000);
  
     l_cursor_handle   integer;
  
  begin
     -- Construct the SQL statement with column names and bind variables e.g.
     -- 'select description from mars.attribute where attribute_id = :b1 and name = :b2'
     for i in t_names.first .. t_names.last loop
        l_sql := l_sql ||
           case i
              when t_names.first then ' where ' else ' and '
           end ||
           t_names(i) || ' = :b' || i;
     end loop;
  
     dbms_output.put_line('SQL statment = ' || l_sql); 
  
     -- Parse the statement we built above (the remaining steps require a parsed cursor):
     l_cursor_handle := dbms_sql.open_cursor;
     dbms_sql.parse(l_cursor_handle, l_sql, dbms_sql.native);
  
     -- Associate the 1st column of output with variable l_value - required for SELECT statements:
     -- (actually the 3rd param here 'column' seems to be only used to get a datatype, in this case we want a string -
     -- dbms_sql.column_value actually extracts the value into a specified variable, which can be different.
     -- All examples in the documentation pass a local variable without further comment, so not entirely clear what this does other than set the output datatype.)
     dbms_sql.define_column(l_cursor_handle, 1, l_value, 4000);
  
     -- Now go through values array binding actual values to :bn variables in the cursor (similar to USING clause of EXECUTE IMMEDIATE)
     for i in t_values.first .. t_values.last loop
        dbms_sql.bind_variable(l_cursor_handle, ':b'||i, t_values(i));
        dbms_output.put_line('Bound :b'||i || ' as ' || t_values(i));

• The concatenation of the EXECUTE IMMEDIATE statement.

  Hi all
  
  The situation is that I am trying to find all customers whose Date of birth (DOB) is greater than or equal to 150 days. Unfortunately, when I run this SQL I get the error message:
  (1) ORA-00904: "FEB": invalid identifier
  (1) ORA-06512: at line 4 level
  
  I'm not sure what I should do to solve this problem, I hope you can help.
  
  Note: I have to encapsulate this statement in an immediate execution due to problems of roles/Privilidge. In the full version, I also use AUTHID CURRENT_USER.
  
  
  

  DECLARE
      curr_date Date := SYSDATE;
  BEGIN
      EXECUTE IMMEDIATE ' SELECT  cust_name,
                                  cust_dob, -- date of birth
                                  cust_shoe_size
                          FROM    tblCustDetails c
                          WHERE   SUBSTR(c.cust_name, 1,7) = ''Bob''
                                  AND cust_dob >= NEXT_DAY(' || curr_date ||' - 150 , ''SATURDAY'')
                           ';
  END;

  Edited by: DaveyB February 23, 2012 08:39

  The right way to use dynamic queries like this would get stuck in the variables you use... for example

  DECLARE
      curr_date Date := SYSDATE;
  BEGIN
      EXECUTE IMMEDIATE ' SELECT  cust_name,
                                  cust_dob, -- date of birth
                                  cust_shoe_size
                          FROM    tblCustDetails c
                          WHERE   SUBSTR(c.cust_name, 1,7) = ''Bob''
                                  AND cust_dob >= NEXT_DAY(:1 - 150 , ''SATURDAY'')
                           ' USING curr_date;
  END;
  

  However, you also have to take into account the fact that the results of the query are currently disappearing into the ether, so you need an INTO statement...

  DECLARE
      curr_date Date := SYSDATE;
  BEGIN
      EXECUTE IMMEDIATE ' SELECT  cust_name,
                                  cust_dob, -- date of birth
                                  cust_shoe_size
                          FROM    tblCustDetails c
                          WHERE   SUBSTR(c.cust_name, 1,7) = ''Bob''
                                  AND cust_dob >= NEXT_DAY(:1 - 150 , ''SATURDAY'')
                           ' INTO var1, var2, var3 USING curr_date;
  END;
  

  ensure that your variables are declared as appropriate, and then...

  ... you have to take into account the possibility that there is more than 1 line returned, in which case you will have the results of the query to a collection.

  Of course, it is useless for dynamic SQL statements in the first place...

  DECLARE
      curr_date Date := SYSDATE;
  BEGIN
    SELECT  cust_name,
            cust_dob, -- date of birth
            cust_shoe_size
    INTO    var1, var2, var3
    FROM    tblCustDetails c
    WHERE   SUBSTR(c.cust_name, 1,7) = 'Bob'
    AND     cust_dob >= NEXT_DAY(curr_date - 150 , 'SATURDAY');
  END;
  

  still, you should always take into account the bulk collection in a collection if it were going to be more than one row returned.

• Storing the values of execute immediate instruction.

  Hi all
  I execute immediate statement that gets several rows at a time. I need to save this picture and print. Pleas elte the syntax me to use an array or temp table in oracle. See the code provided below.
  Thank you...

  When the output c_tbl % notfound;
  v_stmt: = 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME =' | " ' || r_tbl | " ' |' and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME = (select 'INDEX_NAME' from DBA_INDEXES where TABLE_NAME =' | ")) ' || r_tbl | " ((' |' and UNIQUENESS = "UNIQUE"))';

  v_sqlcode: = SQLCODE;
  If v_sqlcode = 0
  then dbms_output.put_line (v_ct);
  end if;
  end loop;
  close c_tbl;
  end;

  Your immediate question seems to be answered.

  I would like to point out a few problems with your code, however.

  First of all, it seems pointless to use dynamic SQL here - you can use a static SQL statement to get the same data. You can use static SQL, you should.

  Secondly, if you want to use dynamic SQL statements, you should really use bind variables. Something like

    v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME= (select "INDEX_NAME" from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))';
    execute immediate v_stmt
        bulk collect into v_ct
      using r_tbl, r_tbl;
  

  Third, your deepest query is to select the literal 'INDEX_NAME' rather than the name of the actual index. Unless you happen to have an index named INDEX_NAME, who is likely to be a mistake.

    v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME= (select INDEX_NAME from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))';
    execute immediate v_stmt
        bulk collect into v_ct
      using r_tbl, r_tbl;
  

  Fourth, unless you can be sure that the table has a unique index, your query will return an error because the deepest returns multiple lines.

    v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME in (select INDEX_NAME from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))';
    execute immediate v_stmt
        bulk collect into v_ct
      using r_tbl, r_tbl;

• Help needed dynamic query

  Hai I want dynamic query for framing
  

  CREATE TABLE PI4 (COR varchar2(1),dep varchar2(3),cod_rc varchar2(2))

  UPDATE PI4         
          SET
       PI4.COR = ’O’
  WHERE
       PI4.DEP IN ('A01','A02','A03')
  OR
       (

       AND
       PI4.COD_RC = '5L'
       )

  sql_stament is that the variable must be set to above code.
  
  Pls help
  
  
  S

  Check below the code where the CO value is assigned dynamically to a p_cor variable

  DECLARE
  v_sql_statement VARCHAR2(32767) := NULL;
  p_cor VARCHAR2(10) := 'O';
  BEGIN
  v_sql_statement := 'UPDATE PI4 SET PI4.COR ='||p_cor||' WHERE (PI4.DEP IN (''A01'',''A02'',''A03'') OR (PI4. dep IN (''DAC'',''FTS'',''G12'') AND PI4.COD_RC = ''5L''))';
  EXECUTE IMMEDIATE v_sql_statement;
  END;
  

  If you do not need dynamic query to perform the update:

  See the code below:

  DECLARE
  p_cor VARCHAR2(10) := 'O';
  BEGIN
  UPDATE PI4 SET PI4.COR =p_cor WHERE PI4.DEP IN ('A01','A02','A03') OR (PI4. dep IN ('DAC','FTS','G12') AND PI4.COD_RC = '5L'));
  END;

  run immediately v_sql in v_count using v_num;

  Thank you

  You can not choose a column dynamically by passing as a bind value because the binding for the name of the column would be simply considered as a string, in this case a count of the a non-empty string would be the same as count (*), a separate of a non-empty string account would be 1, and an empty string County 0 , which is not a lot get you if you try to count the number of records with non-null to a column values.

  As a dynamically selected column you must can dynamicaly would build the SQL, but opens you up to SQL Injection attacks:

  DECLARE
    v_col varchar2(100) := 'null)+max((select empno from emp where ename=''CLARK'')';
    v_sql VARCHAR2(4000);
    v_count number;
  begin
    v_sql := 'select count('||v_col||') from emp where deptno = :a';
    execute immediate v_sql into v_count using 30;
    dbms_output.put_line(v_count);
  end;
  /
  

  a better approach would be to first make sure that the value of v_col is actually a column in the table:

  DECLARE
    v_col varchar2(100) := 'null)+max((select empno from emp where ename=''CLARK'')';
    v_sql VARCHAR2(4000);
    v_count number;
  begin
    begin
      select column_name into v_col from all_tab_cols
       where owner = 'SCOTT' and table_name='EMP' and column_name = v_col;
    exception when NO_DATA_FOUND then
      v_col := '*';
    end;
    v_sql := 'select count('||v_col||') from scott.emp where deptno = :a';
    execute immediate v_sql into v_count using 30;
    dbms_output.put_line(v_count);
  end;
  / 
  

  Use a box or decode statement in your selection to determine which column to use based on a variable binding:

  DECLARE
    v_col varchar2(100) := 'COMM';
    v_sql VARCHAR2(4000);
    v_count number;
  begin
    v_sql := 'select count(case :col_name '||
                          'when ''ENAME'' then ename '||
                          'when ''COMM'' then to_char(COMM) '||
                          'end) '||
               'from scott.emp where deptno = :a';
    execute immediate v_sql into v_count using v_col, 30;
    dbms_output.put_line(v_count);
  end;
  /

  I want to update a table with immediate execution, but I need to use the variable to run immediately. I typed a code, but the code below does not work and I m getting the error ORA-00936. Something wrong with this code?

  WHILE v_acu_payment_amount > 0

  LOOP

  BEGIN

  SELECT emplid, amount_past_due

  IN v_emplid, v_vade_tutari

  OF vade_temp

  WHERE the sira = v_sirano AND emplid IN (r1.emplid);

  END;

  v_acu_payment_amount: = v_acu_payment_amount - v_vade_tutari;

  Dbms_output.put_line ('paymentamount2' | v_acu_payment_amount);

  IF v_acu_payment_amount > 0

  THEN

  EXECUTE IMMEDIATE "update vade_temp set AMOUNT_PAST_DUE = to_number('||) 0

  || ') where sira = to_number (')

  || v_sirano

  || ')';

  ON THE OTHER

  Temp: = v_acu_payment_amount * (-1);

  Dbms_output.put_line (temp);

  EXECUTE IMMEDIATE "update vade_temp set AMOUNT_PAST_DUE = to_number (')"

  || Temp

  || ') where sira = to_number (')

  || v_sirano

  || ')';

  END IF;

  COMMIT;

  v_sirano: = v_sirano + 1;

  END LOOP;

  Kind regards

  Gunce

  In addition, you have no dynamic SQL for this

  [code]

  WHILE v_acu_payment_amount > 0

  LOOP

  BEGIN

  SELECT emplid, amount_past_due

  IN v_emplid, v_vade_tutari

  OF vade_temp

  WHERE the sira = v_sirano AND emplid IN (r1.emplid);

  END;

  v_acu_payment_amount: = v_acu_payment_amount - v_vade_tutari;

  Dbms_output.put_line ('paymentamount2' | v_acu_payment_amount);

  IF v_acu_payment_amount > 0

  THEN

  UPDATE vade_temp

  SET amount_past_due = 0

  WHERE the sira = v_sirano;

  ON THE OTHER

  Temp: = v_acu_payment_amount * (-1);

  Dbms_output.put_line (temp);

  UPDATE vade_temp

  SET AMOUNT_PAST_DUE = temp

  where sira = v_sirano;

  END IF;

  COMMIT;

  v_sirano: = v_sirano + 1;

  END LOOP;

  [/ code]

  But if you need dynamic sql statements, then you should use bind variables as

  ...

  EXECUTE IMMEDIATE "UPDATE vade_temp SET amount_past_due =: b1 WHERE sira =: b2' using 0, v_sirano;"

  ...

• Maximum size of EXECUTE IMMEDIATE

  Hellou everyone,

  I would like to ask if there is a way how to run the dynamic SQL CREATE or VIEW of REPLACE command more than 32 KB of wholesale. Because the EXECUTE IMMEDIATE statement can run up to 32 k (greater length of variable plsql chain) chain

  Is there a way how children Ridge or replace the command?

  Or I need to revrite using DBMS_SQL.

  Thank you.

  (a) WHY? If you want to dynamically create views?  This is not recommended because your application/database should be designed at the time of the design, not running.

  (b) If you are on 11 g, you can use the CLOB datatype with immediate execution, so there is no 32 K limit.

  (c) If you are before 11 g you need to update, but if you can't then the following example is how you do it using DBMS_SQL.

  SQL > declare

  2 v_large_sql clob.

  3 v_num number: = 0;

  number of v_upperbound 4;

  5 v_sql dbms_sql.varchar2s;

  6 whole v_cur;

  number of v_ret 7;

  8 v_join_sql varchar2 (100): = ' crΘer view vw_tmp as ";

  9 start

  10. build a very big SQL statement in the CLOB

  11 loop

  12 v_large_sql: = v_large_sql | v_join_sql | "select" the number of this line is: ' | TO_CHAR (v_num, 'fm0999999') | " "as col1 from dual;"

  13 v_join_sql: = "union all";

  14 v_num: = v_num + 1;

  15 exit when dbms_lob.getlength (v_large_sql) > 40000 or v_num > 800;

  16 end loop;

  17 dbms_output.put_line (' length :'||) DBMS_LOB. GetLength (v_large_sql));

  18 dbms_output.put_line ('Num :'|| v_num);

  19-

  20. now divide this big SQL statement into pieces of 256 characters and put in table VARCHAR2S

  21 v_upperbound: = ceil ((v_large_sql) dbms_lob.getlength / 256);

  22 because me at 1.v_upperbound

  23 loop

  24 v_sql (i): = dbms_lob.substr (v_large_sql

  25, 256 - amount

  26, ((i-1) * 256) + 1 - offset

  27                                 );

  28 end of loop;

  29-

  30. now analyze and execute the SQL statement

  31 v_cur: = dbms_sql.open_cursor;

  32 dbms_sql.parse (v_cur, v_sql, 1, v_upperbound, dbms_sql.native, false);

  33 v_ret: = dbms_sql.execute (v_cur);

  34 dbms_output.put_line ("' view created");

  35 dbms_sql.close_cursor (v_cur);

  36 end;

  Dear all,

  During the race the query below, it takes a long time to execute.

  Can you please help me on this issue.

  I use the version of Oracle 11 g.

  Thanks a lot for your help.

  Never perform a treatment by data line. SET the computer base. Direct use of the joints and cut single SQL. Your condition can be obtained by using the merge statement.

  merge into customer_alignment c
  using (
          select vw.affiliation_id
               , ca.customer_alignment_id
            from customer_alignment c
            join tenant t
              on t.tenent_id       = c.tenent_id
             and t.tenent_id       != 0
             and c.affiliation_id is null
            join customer_alignment ca
              on ca.alignment_id  = c.alignment_id
             and ca.affiliation_id is null
            join ca_primary_address_vw vw
              on ca.customer_id   = vw.customer_id
             and ca.alignment_id  = vw.alignment_id
        ) t
     on (
           c.customer_alignment_id = t.customer_alignment_id

   when matched then
   update

• Unit test: is there a way to make the dynamic query of the value of running after the boot process?

  I wonder why the dynamic value query is executed before the boot process? Logically, it makes sense to run after them.

  For example, I test a stored procedure that is supposed to delete a record, and I'd like to create this test report should be deleted as part of the startup process before execution of the stored procedure call to delete this test record. Apparently the dynamic query of value not returns not the test report in as long as the query parameter to call the stored procedure under test, which makes me think that is executed before the startup process of design...

  Please advise...

  Thank you

  As this thread does no traction/attention of the team of SQL Developer for a while, I had to submit a request for formal improvement on metalink:

• Execute Immediate with DOF and TABLE() - error ORA-22905

  Hello

  I have a problem trying to use a user defined the Type of the Table in a statement Execute Immediate containing a CREATE TABLE statement.

  Is there no work around for this problem?

  The actual code for the SELECT * OF TABLE(:T) is dynamic and slow. That's why I try to avoid to create/fill the table in two steps (as does with MY_TABLE1). Also, in this case, I can't use SELECT * but must specify all the columns (amount variable and over 100 columns).

  CREATE TYPE MY_TABLE_TYPE AS TABLE OF VARCHAR2(30);
  /
  DECLARE
      MT MY_TABLE_TYPE;
  BEGIN
      SELECT * BULK COLLECT INTO MT FROM DUAL;
      -- Two steps
      EXECUTE IMMEDIATE 'CREATE TABLE MY_TABLE1 (A VARCHAR2(30))';
      EXECUTE IMMEDIATE 'INSERT INTO  MY_TABLE1    SELECT * FROM TABLE(:T)' USING MT; -- OK
      -- One step
      EXECUTE IMMEDIATE 'CREATE TABLE MY_TABLE2 AS SELECT * FROM TABLE(:T)' USING MT; -- ERROR ORA-22905   
  END;
  /

  In my view, the error message is incorrect or the less misleading. Bind variables cannot be used in DDL:

  SQL > declare
  2 number of v_var: = 99;
  3. start
  4 run immediately "' create the my_table2 in select table: double T" using v_var; "
  5 end;
  6.
  declare
  *
  ERROR on line 1:
  ORA-01027: bind variable not allowed for data definition operations
  ORA-06512: at line 4 level

  What you could do is use the package variable:

  SQL > CREATE OR REPLACE
  2 PACKAGE PKG1
  3 EAST
  4 MT MY_TABLE_TYPE;
  5 FUNCTION GET_MT
  6 RETURN MY_TABLE_TYPE;

• Need help tuninng a dynamic query

  Hello

  We have following question

  Select s.* s bose_sites.registration_crm_serial_number

  R2 bose_sites.registration_crm_serial_number left on join

  s.serialnr = r2.shipserialnr

  where s.shipserialnr is null

  and (r2.serialnr = ' 052378332000138AE' or (s.serialnr =)

  (( "052378332000138AE" and s.shipserialnr is null))

  which takes about 40 seconds to execute with the values highlighted in bold being dynamic values

  If anyone can help reduce the run time on this request.

  There are indexes created on table

  INDEX_NAME INDEX_TYPE

  ------------------------------ ---------------------------

  IDX_REG_CRM_SER_NUM_CPC NORMAL

  IDX_REG_CRM_SER_NUM_SHIPDATE NORMAL

  IDX_REG_CRM_SER_NUM_PARENT_ID NORMAL

  IDX_REG_CRM_SER_NUM_ID NORMAL

  is it possible that we can capture a dynamic query using DBMS_SQLTUNE

  all suggestions will be useful.

  Hello

  You have one table here
