Thread: EXECUTE command in stored procedure

Dear All,

How can I use EXCEUTE command in stored procedures?
When using like this

EXECUTE 'SELECT INTO REGNO REG_NO FROM ADMISSION WHERE SNAME = ' || STUDNAME ;

STUDNAME is a local variable;

I am getting error like this

ERROR:  syntax error at or near "INTO" at character 8

How can I solve this.

Regards,

You don't mention which version of PostgreSQL you are using, or which
stored procedure language.  I'll assume 8.1.x and PL/pgSQL.  See section
36.6 in the documentation.  Specifically, 36.6.5 says:

"SELECT INTO is not currently supported within EXECUTE."

However, if I'm understanding what you are trying to do, you shouldn't
need the EXECUTE at all.  Doing a simple SELECT INTO should work for
you.  Note also that since you are only retrieving a single value, you
can also avoid INTO altogether with something like:

REGNO := (select regno from admission where sname = myname);
