Re: Dynamic procedure execution - Mailing list pgsql-general

Hi Adrian Klaver,

Sorry for typo mistake. Instead of writing lengthy query, I had written it simple. Actually my main concept is to bring result set with multiple rows (using select query) with help of dynamic query.

When calling that procedure in Pgadmin4 window, simply getting the message as ‘ CALL     Query returned successfully in 158 msec’.

FYI, I have implemented simple dynamic query for UPDATE and DELETE rows. It is working fine without any issues. 

Please let me know is there any way of getting result set using dynamic query.

Issue with dynamic select:-

CREATE OR REPLACE Procedure sp_select_dynamic_sql(                              

                keyvalue integer)  

    LANGUAGE 'plpgsql'

AS $BODY$

Declare v_query text;

BEGIN

                v_query:= 'select * from Los_BankInfo '

        || ' where pk_id = '

        || quote_literal(keyvalue);

                execute v_query;

                END;

$BODY$;

Execuion of Proc:-

CALL sp_select_dynamic_sql (11);

Output:-

CALL

Query returned successfully in 158 msec.

Working fine with Dynamic UPDATE and DELETE Statement :-

UPDATE:-

CREATE OR REPLACE Procedure sp_Update_dynamic_sql(

                newvalue varchar(10),                  

                keyvalue integer)  

    LANGUAGE 'plpgsql'

AS $BODY$

Declare v_query text;

BEGIN

                v_query:= 'update Los_BankInfo set approverid'       

        || ' = '

        || quote_literal(newvalue)

        || ' where pk_id = '

        || quote_literal(keyvalue);

        execute v_query;

                END;

$BODY$;

--CALL sp_Update_dynamic_sql (john,10);

DELETE:-

CREATE OR REPLACE Procedure sp_Delete_dynamic_sql(                            

                keyvalue integer)  

    LANGUAGE 'plpgsql'

AS $BODY$

Declare v_query text;

BEGIN

                v_query:= 'delete from Los_BankInfo '

        || ' where pk_id = '

        || quote_literal(keyvalue);

                execute v_query;

                END;

$BODY$;

--CALL sp_Delete_dynamic_sql(10);
