Re: PLPGSQL: How can I get the effected rows when use "execute" command in function

Dear all,

Can I get the effected rows after executing sqls in function?
e.g.:

CREATE OR REPLACE FUNCTION execsqls(sqls character varying)
RETURNS integer AS
$BODY$
DECLARE
BEGIN
EXECUTE sqls;
-- TODO-1: I want to know how many records the input sqls
effects?
RETURN effectedRows;
END;
$BODY$
LANGUAGE plpgsql;

test: select execsqls('update mytable where name like ''%abc''')

Hello

yes, you can. Look on GET DIAGNOSTICS statement

if you are doing insert, update or delete you can use "retuirng" command in the query, work with a cursor to get the rows
