How to execute the content of varchar variable like a simple query

Question

Hi everyone!
I did a PL/SQL region in apex, in this region I did the query which is storaged in a variable; it was did it concatenate several times,
in the procedure I have several sentences.
I thought that the command 'execute immediate' would get a good result but it do not print the result.
declare
variable varchar2(1000);
begin
--sentences
--execute inmmediate( variable );
--return variable
end;
I only want to how to execute the content of varchar variable.
For example, suppose that the result of this procedure is
'SELECT SYSDATE FROM DUAL'
How and what do I must do for this query execute like a normal query that is in apex?
I expect your prompt reply.
Thank you for your help.
Best regards

Answer 1

Let us say your table containing SQL is
t_sql_table
and has two columns
primary_key
and
sql_query.
You would need to do the following:
1. Create a Report of type "Function returning SQL Query"
2. Put the following there:
DECLARE
   v_query   VARCHAR2 (4000);
BEGIN
   SELECT sql_query
     INTO v_query
     FROM t_sql_table
    WHERE primary_key = 1;
   RETURN v_query;
