• suffixing date in the EXECUTE IMMEDIATE statement

  Hi could one please let me know how I can the suffix of the name of the table to the year, which the calculation is being in the select statement. Output should be as an example: test_2007

  declare
  
  abc number;
  
  begin
  
     select (to_char(sysdate, 'YYYY') - 4) into abc from dual;
  
     EXECUTE IMMEDIATE 'CREATE TABLE test_&abc as select * from emp where 1=2';
  
  end;

  You can do it like this

  BEGIN
     EXECUTE IMMEDIATE
           'CREATE TABLE test_'
        || (TO_CHAR ( SYSDATE, 'YYYY') - 4)
        || ' as select * from emp where 1=2';
  END;
  

  You can use your variable as well, if this can change dynamically.

  DECLARE
     abc            NUMBER;
  BEGIN
     SELECT (TO_CHAR ( SYSDATE, 'YYYY') - 4) INTO abc FROM DUAL;
  
     EXECUTE IMMEDIATE 'CREATE TABLE test_'||abc||' as select * from emp where 1=2';
  END;

• Creating external Tables using the EXECUTE IMMEDIATE in PL/SQL

  Hi guys,.
  
  I am trying to create an external Table using the EXECUTE IMMEDIATE in a procedure and I managed to compile and no errors were generated. But when I try to run it from sql using the exec command I get the following error:
  
  ------------------------------------------------------------------------
  ERROR on line 5:
  ORA-00911: invalid character
  ORA-06512: at "GEO. TEST_DDL', line 4
  ORA-06512: at line 5
  
  -------------------------------------------------------------------------
  
  I tried to check the whole statement to create the external table, but I can't find where is the error. Surprisingly, if I simply run the command table create external on sqlplus it works, but not a procedure.
  
  If anyone can help with ideas or experience?
  
  Geoffrey Kossami

  The error means that there is an identifier somewhere that starts with a nonalphanumeric. This is a typical mistake of editing. A procedure compiles correctly is not of course because the underlying dynamic sql running is OK. Which of course only be resolved when you try to run it.

  There is certainly a problem with the text you provide to be run as a piece of dynamic sql code. You should try to watch it with dbms_output and run this code in sqlplus. But your problem is with the code you run as dynamic PL/SQL, it is not itself compilable.

  Well, dynamic sql is executed in a separate context and scope. V_barg_unit stated in your code is therefore not visible in the dynamic PL/SQL block you run. You can pass block dynamic PL/SQL using the variable binding and the USING clause:

  DECLARE
      cmd VARCHAR2 (4000);
      v_barg_unit VARCHAR2 (10) := 'ABC';
      v_bg_group VARCHAR2 (10) := ' ';
  
  CURSOR abc
  IS
  SELECT * FROM test_dynamic_if_tbl;
  BEGIN
  FOR c1 IN abc
  LOOP
  cmd :=
  'declare v_barg_unit VARCHAR2 (10);
  Begin
  v_barg_unit := :v_barg_unit;
  If ' || c1.condition
  || ' THEN '
  || c1.result_val
  || ' ; End if;
  End;';
  DBMS_OUTPUT.put_line ('cmd: ' || cmd);
  
  EXECUTE IMMEDIATE cmd USING v_barg_unit,OUT v_bg_group;
  
  DBMS_OUTPUT.put_line ('Condition: ' || c1.condition);
  DBMS_OUTPUT.put_line ('result_value: ' || c1.result_val);
  DBMS_OUTPUT.put_line ('v_bg_group: ' || v_bg_group);
  END LOOP;
  END;
  

  However, since you do not know what name will be stored in test_dynamic_if_tbl my suggestion is not a generic solution.

• 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.

  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);

  I noticed that you have placed the variables, this time taking the table_name and column_name inside quotes values, it is a possible workaround for the issue or is there another method I could use to get the same results?

  If you have N tables with columns of M your code will run statements N * Mr. If the tables are large, it might take some time. Now how about double quotes. You may receive error on the basis I assumed you have names of tables/columns composed of several words. You must include these names in quotation marks. Discover Oracle naming rules.

• Storing the values of execute immediate instruction.

  Thank you...
  declare

  r_tbl VARCHAR2 (150);
  cursor c_tbl is

  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;

  EXEC is a more SQL API which can be used to execute the PL/SQL code. What it does is put the PL/SQL code in a BEGIN block... END of block and run.

  So, you can also manually put code in a BEGIN block... END of block and run like that.

  And I don't understand what possible benefit he made a single run in a BEGIN block... Terminate during execution of multiples.

  Why this code is not in your interest, something like this

       execute immediate 'alter session set nls_language = ''AMERICAN''';

  Here is the list of question I see in this code.

  1. in the SQL string, you must have a after the keyword and before the GROUP BY keyword.

  2. you should not use ';' in EXECUTE IMMEDIATE. You must remove it.

  3. the result set returned by the EXECUTE IMMEDIATE should be stored in a Variable. You use the INTO LEDGES INTO clause or in BULK to this effect.

• Execute Immediate and by calling a function

  I'm calling a function by using the Execute Immediate, but not sure what the correct syntax for the function's return value after the Execute Immediate runs.
  
  I need the value for further processing in my PL/SQL package.
  
  I tried several methods, but cannot get the right format for this work/compilation.
  
  
  EExecute Immediate plsql_block back in ShName2;
  
  Have been that plsql_block has the code to:
  Declare shname2 varchar2 (4000); Begin shname2: = lurking. ShortNm ('STRUCTURE'); End;

  Function created.
