Hi,
I would like to assign a query to a bind variable using query string. Query spawn across multiple rows (100s of lines having union all satements).
The below sample code works alright from a script file
variable c clob;
exec :c:= q'[select * from dual where 'bb'='bb']'
But error is thrown when the query is split across multiple lines.
variable c clob;
exec :c:= q'[select * from dual
where 'bb'='bb']'
exec :c:= q'[select * from dual
*
ERROR at line 1:
ORA-00900: invalid SQL statement
Appending '-' at the end of the line will solve the problem but is there any alternative approach as this leads to appends 100s of line with '-'
Thank you in advance for your time.
Regards,
Pointers

Thank you for the details.
I could declare all the queries by assigning to PL/SQL variables inside an anonymous block.
But I would like to have this in a separate script (say "first.sql") and refer these variables in different script (say "second.sql").
In the second script, all these variables are passed as arguments to a function which executes the query and generates CSV file.
How could this be achieved.
Thank you in advance.
Regards,
Pointers

Is it not the same question you asked in the previous topic (http://www.orafaq.com/forum/t/200064/)?
According to EXECUTE vs. PL/SQL block - as you used two EXECUTE statements, just use (and execute) two PL/SQL blocks. The manipulation with the bind variables will stay unchanged.
I am not sure what "I could declare all the queries by assigning to PL/SQL variables inside an anonymous block." exactly means.
But, if you mean declaring the variables inside the PL/SQL blocks, you do not have to do it (change the current code), so just do not do it. Any problem?

SQL*PLus command EXECUTE requires single line. You can use dash which is line continuation character (when used as last character):
SQL> variable c clob;
SQL> exec :c:= q'[select * from dual -
> where 'bb'='bb']'
PL/SQL procedure successfully completed.
SQL>
However technically it is not the same:
SQL> variable c clob;
SQL> exec :c:= q'[select * from dual -
> where 'bb'='bb']'
PL/SQL procedure successfully completed.
SQL> print c
C
-----------------------------------------------
select * from dual where 'bb'='bb'
SQL> begin
2 :c := q'[select * from dual
3 where 'bb'='bb']';
4 end;
5 /
PL/SQL procedure successfully completed.
SQL> print c
C
-----------------------------------------------
select * from dual
where 'bb'='bb'
SQL>
SY.
