• dynamic query problem

  Hello

  I am trying to understand the procedure and on the inside, I have a dynamic query with where clause:

  "Select."

  tables

  where 1 = 1

  and instr (decode (nvl (' | nvl(pCATEG,'') |))) (("*"), "*", pb.categ, upper (' | nvl(pCATEG,'') |), pb.categ) > 0'

  || NVL(pEMP_GROUP_CODE,'') |

  "and p.emp_group_code = g.emp_group_code';"

  For it, clause make sense (parameter pEMP_GROUP_CODE is not connected to any condition, or I missed something)?

  The procedure is works and connected to the application.

  Please notify

  Thank you

  Daniel

  Has been confused by "p.emp_group_code".

  What you see is probably a lexical parameter, for example the value passed on s pEMP_GROUP_CODE a condition itself as 'and table.column = 'constant', which can be zero, so if you have a value, it adds a condition, otherwise just empty space and the condition is spared.

• A difficult dynamic SQL query problem

  Hi all
  
  I have a very interesting problem to work:
  
  We have this special table defined as follows:
  
  CREATE TABLE sales_data)
  sales_id NUMBER,
  NUMBER of sales_m01
  NUMBER of sales_m02
  NUMBER of sales_m03
  NUMBER of sales_m04
  NUMBER of sales_m05
  NUMBER of sales_m06
  NUMBER of sales_m07
  NUMBER of sales_m08
  NUMBER of sales_m09
  NUMBER of sales_m10
  NUMBER of sales_m11
  NUMBER of sales_m12
  sales_prior_yr NUMBER);
  /
  
  Columns ' sales_m01... sales_m12' represents aggregated monthly sales, what "sales_m01" is translated by "sales for the month of January, January is the first month,"sales_m02"in sales for the month of February and so on.»
  
  The problem I encounter is that we have a project that requires that a parameter is passed to a stored procedure that represents the number of months which is then used to create a SQL query with aggregations of next mandatory field, which depends on the parameter passed:
  
  Example 1: entry of parameter: 4
  Should be built dynamically to SQL query:
  
  SELECT
  Sum (sales_m04) as CURRENT_SALES,
  Sum (sales_m01 + sales_m02 + sales_m03 + sales_m04) SALES_YTD
  Of
  sales_data
  WHERE
  sales_id = '0599768';
  
  Example 2: input parameter: 8
  Should be built dynamically to SQL query:
  
  SELECT
  Sum (sales_m08) as CURRENT_SALES,
  SUM (sales_m01 + sales_m02 + sales_m03 + sales_m04 +)
  sales_m05 + sales_m06 + sales_m07 + sales_m08) SALES_YTD
  Of
  sales_data
  WHERE
  sales_id = '0599768';
  
  
  So in a sense, the contents of SUM(sales_m01...n) would vary according to the parameter, which must be a number between 1... 12 what is a month, which in turn corresponds to a range of real field on the table itself. The resulting dynamic query should include only those columns/fields in the table that is within the range given by the input parameter and does not account for all the other columns/fields.
  
  Any solution is greatly appreciated.
  
  Thank you.

  SQL> declare
    cols long;
    param integer := 6;
    sales_id integer := 0599768;
  begin
    for i in 1..param loop
      cols := cols || 'sales_m' || to_char(i, 'fm00') || '+';
    end loop;
  
    dbms_output.put_line('select sum(sales_m'||to_char(param,'fm00')||') current_sales, sum(' || rtrim(cols,'+') || ') sales_ytd from sales_data WHERE sales_id = :1');
  end;
  /
  select sum(sales_m06) current_sales, sum(sales_m01+sales_m02+sales_m03+sales_m04+sales_m05+sales_m06) sales_ytd from sales_data WHERE sales_id = :1
  PL/SQL procedure successfully completed.
  

  Now it should be obvious:
  Instead of dbms_output OPEN a refcursor:

  SQL> declare
    cols long;
    param integer := 6;
    sales_id integer := 0599768;
    cur sys_refcursor;
  begin
    for i in 1..param loop
      cols := cols || 'sales_m' || to_char(i, 'fm00') || ',';
    end loop;
  
    open cur for 'select sum(sales_m'||to_char(param,'fm00')||') current_sales, sum(' || rtrim(cols,',') || ') sales_ytd from sales_data WHERE sales_id = :1' using sales_id;
    .....
  end;
  /

  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

  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.

• dynamic query for package does not work

  Dear members,
  
  I have problems with a package in the creation and analysis of a dynamic query in the WHERE clause. Here is an example of what I'm trying to do:
  
  PROCEDURE test_status_proc)
  wtd_cursor ON cur_type
  date_1 IN date
  date_2 IN DATE
  status in VARCHAR2,
  flag in VARCHAR2)
  
  IS
  
  status_sql VARCHAR2 (250): = NULL;
  flag_sql Varchar2 (100): = NULL;
  
  BEGIN
  
  
  Status of the IF = 'A' THEN
  lv_status_sql: = 'A ';
  lv_flag_sql: = 'Y ';
  END IF;
  Status of the 'I' = IF THEN
  lv_status_sql: = 'A ';
  lv_flag_sql: = 'n';
  END IF;
  
  Status of the 'R' = IF THEN
  lv_status_sql: = "R";
  lv_flag_sql: ='* ';
  END IF;
  
  Status of the IF = n THEN
  lv_status_sql: = 'n';
  lv_flag_sql: ='* ';
  END IF;
  
  IF status_code = 'IRN' THEN
  "lv_status_sql: = '('' N'','' R'');
  lv_status_sql: = lv_status_sql | ' OR (s.status = s.flag = "A" AND "N")';
  lv_usecalc_sql: ='* ';
  END IF;
  
  Status of the = IF'* ' THEN
  lv_status_sql: ='* ';
  lv_flag_sql: ='* ';
  END IF;
  
  OPEN FOR Test_cursor
  
  SELECT * from test_status s
  WHERE
  s.Daytime BETWEEN date_1 AND date_2
  S.status AND decode (lv_status_sql,'* ', s.status, lv_status_sql)
  S.flag AND decode (lv_flag_sql,'* ', s.flag, lv_flag_sql);
  
  The problem I have is especially with the condition 'IRN '. The suite WHERE the part of the clause looks like the following in the lv_status_sql, but the query returns all the values:
  
  -(', 'R') OR (s.status = 'A' AND s.flag =' only)
  
  Any help would be much appreciated.
  
  Kind regards

  Thanks for your reply and I completely understand your frustration. The problem is sometimes it is very difficult to describe all of the problem due to several reasons. Please take a look at my last post to see if that makes sense.

  If you really need SQL dynamic - true dynamic SQL which includes dealing with dynamic number of bind variables - then DBMS_SQL are an excellent interface to use.

  You can generate the dynamic SQL statement based on the question of whether the filter criteria is null (do not use) or not null (use as a predicate). For example

  if someParam10 is not null then
    // someParam10 needs to be used as a filter predicate
    dynamicSQL := dynamicSQL || ' and some_col_10 = :someParam10 ';
  end if;
  

  This statement can then be analyzed using the DBMS_SQL interface. The binding of values uses the same logic that was used to create predicates. For example

  if someParam10 is not null then
    // someParam10 is used and needs to be bound
    DBMS_SQL.Bind( myCursor, 'someParam10', someParam10 );
  end if;
  

  So, with this approach simplistic, you can easily create a dynamic SQL with variable predicates, dynamically bind these and run the slider.

  Bind variables are used in the dynamic SQL statements, as there are very few threats of SQL injection. And the basic principles observed for shareable SQL creation - the same set of parameters not null to filter, will result in the same SQL statement, which allows the cursor within the Pool shared for this SQL statement to be reused.

  So, technically, dynamic SQL is not a major problem (if used correctly). The major problem is that if really necessary to address the requirements of the business at hand.

  The problem I have with many comments here want to use dynamic SQL statements, is that it is used as one would use a file i/o interface.

  For file IO you want standard Open(), Read(), Write() and Close() calls. And you, the appellant, simply pass the name of the file and the data to write or to receive the data read.

  Similarly, these posters want to use SQL to open a table and read and write the data column - and do it by calling simply (and dynamically) by specifying the name of the table and column. Approaches to dynamic SQL based on one such concept is wrong. And shows that much of the ignorance of what a RDBMS is and how to use an RDBMS.

• Get the dynamic query alias name

  Hi all
  
  I have a plsql function using a dynamic query.
  And the function takes an entire sql query as a parameter.
  
  The main problem is that the function must get what aliases or columns were interviewed.
  
  For example,.
  FUNCTION_GET_QUERY_ALIAS ('SELECT 1 AS col1, col2 FROM DUAL 2 AS')
  Inside the function, he must find the alias name COL1 and COL2.
  
  I would be grateful for any help.

  I modified print_table as fact and function to meet your needs.

• 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:

• Need help tuninng a dynamic query

  Hello

  We have following question

  Select s.* s bose_sites.registration_crm_serial_number

  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

  IDX_REG_CRM_SER_NUM_SHIPDATE NORMAL

  IDX_REG_CRM_SER_NUM_PARENT_ID NORMAL

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

  all suggestions will be useful.

• 30EA2 - UNIT TESTING - value dynamic query truncating dates time.

  So I use the installation of SQL Developer Unit Testing (very nice by the by) for a bit now and just recently upgraded to the latest beta version (3.0.02.83). Looks like a bug has been introduced by which the dynamic query of value are truncate all time of all DATE data type information.
  
  This causes sadness serious for my current test cases and for me since I have to go back to the previous beta version :)

  I noticed that, in the new 30EA2 parameter:

  AddVMOption - Doracle.jdbc.mapDateToTimestamp = false

  has been introduced by default in

  [SQLDEveloper_install_dir]/sqldeveloper/bin/sqldeveloper.conf

  Perhaps it has something to do with the behavior of incorrect date, try to remove the parameter and check again.

• Help needed dynamic query

  Hai I want dynamic query for framing
  

  CREATE TABLE PI4 (COR varchar2(1),dep varchar2(3),cod_rc varchar2(2))
  
  insert into pi4(dep,cod_rc) values('A01','5C')
  
  insert into pi4(dep,cod_rc) values('DAC','5L')

  HORN must be updated using dynamic query
  as below
  

  UPDATE PI4         
          SET
       PI4.COR = ’O’
  WHERE
       PI4.DEP IN ('A01','A02','A03')
  OR
       (
       PI4. dep IN ('DAC','FTS','G12')
       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;

• How to map Dynamic Query columns on variables of forms.

  Dear all,
  This is a correct code for executing a dynamic query and display data.
  In this program that I have defined variables ("BOLD" of police) later I binds these with the query (in the second code "BOLD").
  
  How I can map a column in the query, in which case I don't know that the surveyed fields type?
  
  
  
  GetData PROCEDURE IS
  EXEC_SQL connection_id. PORT;
  cursorID EXEC_SQL. CURSTYPE;
  sqlstr VARCHAR2 (1000);
  
  loc_ename VARCHAR2 (30);
  loc_eno NUMBER;
  loc_hiredate DATE;
  
  nIgn PLS_INTEGER;
  
  BEGIN
  connection_id: = EXEC_SQL. DEFAULT_CONNECTION;
  cursorID: = EXEC_SQL. OPEN_CURSOR (connection_id);
  --
  -assuming empno is a primary key for the table emp, where clause ensures
  -only 0 or 1 row is returned
  --
  sqlstr: = "select ename, empno, hiredate from emp;
  -sqlstr: = sqlstr. 'where empno =' | input_empno;
  
  EXEC_SQL. PARSE (connection_id, cursorID, sqlstr, exec_sql. V7);

  EXEC_SQL. DEFINE_COLUMN (connection_id, cursorID, 3, loc_hiredate);
  
  --
  -do execute_and_fetch after the analysis of the statement and calling bind_variable and

  If you want to use EXEC_SQL and a dynamic query with unknown data types, but the known table name,
  Then you can declare a rowtype variable
  for example;

   NOT TESTED ---A ROUGH IDEA
  m_emp_row employee_master%rowtype;
  m_col_cnt number := 0;
  So when you define collumn, create a procedure to find the column name and its width if it is varchar2 with respect to the column name .
     Find the column details from the user_tab_columns table ...
  ---------------------------------------------------------------------------------------------------------------------------------------------------
    while m_col_cnt < 3 loop
         m_col_cnt  := m_col_cnt +1;
         proc_find_col_name_width(p_qry ,p_col_no=>m_col_cnt , p_col_name,p_col_width);
  
        If p_col_name = 'EMPCODE' then
           EXEC_SQL.DEFINE_COLUMN(connection_id, cursorID, m_col_cnt , m_emp_row.empcode , p_col_width);
        elsif p_col_name ='EMPNAME' then
           EXEC_SQL.DEFINE_COLUMN(connection_id, cursorID, m_col_cnt , m_emp_row.empname , p_col_width);
         -----
          -------
         end if;
    end loop;
  
  ---------------------------------------------------------------------------------------------------------------------------------------------------
  --Your procedure will look like this
   procedure proc_find_col_name_width(p_qry  varchar2,p_col_no number, p_col_name out varchar2,p_col_width out number) is 
  
   m_col_name varchar2(30);
   Cursor c1 is
   Select  data_length

   where table_name = 'yr_tab_name'
   and column_name = m_col_name;
   m_lastpos number ;
   m_nxtpos number ;
   Begin
    m_lastpos := instr(p_qry,',',1,p_col_no-1);
    m_nxtpos := instr(p_qry,',',1,p_col_no);
    If m_lastpos = 0 then --- if only one col
       m_col_name := substr(p_qry,instr(upper(P_QRY),'SELECT') + 6, instr(upper(P_QRY),'FROM') -1);
    else
         If m_nxtpos = 0 then ---if last column

    open c1;
    fetch c1 into p_col_width;
