going by the line and column no,the error is at v_comments in execute immediate statement. basically i want dynamic column name for v_VAL_DONE_BY and v_Comments. the same execute immediate is working in standalone pl sql block. seems some problem with use of quotes in execute statement could you please help?

Answer 1

Are you running this insert statement in a PL/SQL block? You are using variables in your query that SQL would take for column names (that don't exist) and raise the error. If you are running this code in PL/SQL, then you must of course declare the variables and do something about the bind variable :3 as mentioned by BJones in the comments to your request.

SQL:

Insert into BL_DIFF_QUERY_ANL (TABLE_NAME,ISSUSE,ISSUE_CATEGORY,ISSUE_ID,DB_QUERY)
values ('BILL','TOTAL_BILLED_ADJUST_MISMATCH','TOTAL_BILLED_ADJUST',2,
...
execute immediate ''UPDATE BL_DIFF_CATEGORY SET VALIDATION_STS = :2,' ||
:v_VAL_DONE_BY ||
'='||
:3 ||
','||
:v_comments ||
'= :4  where BAN = :1 and
...
);

PL/SQL

declare
  v_VAL_DONE_BY varchar2(4000);
  v_comments varchar2(4000);
begin
  Insert into BL_DIFF_QUERY_ANL (TABLE_NAME,ISSUSE,ISSUE_CATEGORY,ISSUE_ID,DB_QUERY)
  values ('BILL','TOTAL_BILLED_ADJUST_MISMATCH','TOTAL_BILLED_ADJUST',2,
  ...
  execute immediate ''UPDATE BL_DIFF_CATEGORY SET VALIDATION_STS = :2,' ||
  v_VAL_DONE_BY ||
  '= :3 ,'||
  v_comments ||
  '= :4  where BAN = :1 and
  ...
  );
end;

Update: SQL again

Looking closer at the variable names you are using, I've come to the conclusion that the variables shall be part of the SQL string that you are inserting:

  ...
  execute immediate ''UPDATE BL_DIFF_CATEGORY SET VALIDATION_STS = :2, '' ||
  v_VAL_DONE_BY || '' = :3, '' || v_comments || '' = :4  where BAN = :1 and DIFF_TYPE = :5''
  using v_issue_Desc,v_immediate_Adj,v_yesnoind,v_success,v_ban;

 COMMIT;
 END IF;
END;'
);

Explantion

You want to insert code into your table. This code is a PL/SQL script with variables and strings. This is a small example for such PL/SQL code:

declare
  v_number integer := 5;
begin
  dbms_output.put_line('The number is: ' || v_number);
end;

You want to insert this as a string. But if you merely put single quotes at the start and the end as in

insert into mytable (mycode) values
(
  'declare
     v_number integer := 5;
   begin
     dbms_output.put_line('Number ' || v_number);
   end;'
);

this doesn't work, because the code itself contains single quotes. The DBMS reads the string from the starting quote to the next quote it finds, in this example right before Number. So the DBMS sees a string followed by the word Number and doesn't know what to do with this. Number looks like a column name, but a column name doesn't belong there. (You can see from the syntax highlighting that the DBMS sees two strings with the woprd Number in between.)

The solution is to mask all single quotes with another single quote (i.e. replace ' with '' in your editor):

insert into mytable (mycode) values
(
  'declare
     v_number integer := 5;
   begin
     dbms_output.put_line(''Number '' || v_number);
   end;'
);

All single quote pairs are seen as part of the string now representing a single quote within. The DBMS sees a single string that it can insert into the table now. (You can see from the syntax highlighting that this is one string now.)

In your code you used single quote pairs in some situations but not in all. Maybe you did this just manually instead of search & replace in an editor and thus missed some occurrences.
