Обсуждение: pl-pgsql question
Greetings, I'm writing some stored procedures using pl-pgsql and I need to know how many tuples were affected by a update/delete/insert command. Let's suppose my script is like this : CREATE FUNCTION gerachave(INT4) RETURNS INT4 AS' DECLARE CAD ALIAS FOR $1; BEGIN novovalor := 0; UPDATE table1 SET is_ok = 1 WHERE cod_cad = CAD; INSERT INTO cnfg_gerachave VALUES (<quantity of tuples affected by UPDATE>); RETURN CAD; END; ' LANGUAGE 'plpgsql'; Is it possible to discovery how many tuples were affected? How can I do it? Thanks in advance. ---------------------------------------------------------------------------- ---- José Vilson de Mello de Farias Software Engineer Dígitro Tecnologia Ltda - www.digitro.com.br APC - Customer Oriented Applications E-mail: vilson.farias@digitro.com.br Tel.: +55 48 281 7158 ICQ 11866179
rows INTEGER; UPDATE foo SET bar = ''test''; GET DIAGNOSTICS rows := ROW_COUNT; This will return the number of rows actually updated by the system HTH Darren Vilson farias wrote: >Greetings, > > I'm writing some stored procedures using pl-pgsql and I need to know how >many tuples were affected by a update/delete/insert command. > > Let's suppose my script is like this : > >CREATE FUNCTION gerachave(INT4) RETURNS INT4 AS' >DECLARE > CAD ALIAS FOR $1; >BEGIN > novovalor := 0; > > UPDATE table1 SET is_ok = 1 WHERE cod_cad = CAD; > > INSERT INTO cnfg_gerachave VALUES (<quantity of tuples affected by >UPDATE>); > > RETURN CAD; >END; >' >LANGUAGE 'plpgsql'; > > >Is it possible to discovery how many tuples were affected?

What's the scope of that statement, just the last statement within the same session, all statements within that session,what?

Just the last statement that occurred in that session provided it is an update / delete as far as i know Darren Dennis Gearon wrote: > What's the scope of that statement, just the last statement within the > same session, all statements within that session, what? > > Darren Ferguson wrote: > >> rows INTEGER; >> >> UPDATE foo SET bar = ''test''; >> GET DIAGNOSTICS rows := ROW_COUNT; >> >> This will return the number of rows actually updated by the system >> >> HTH >> Darren >> Vilson farias wrote: >> >>> Greetings, >>> >>> I'm writing some stored procedures using pl-pgsql and I need to >>> know how >>> many tuples were affected by a update/delete/insert command. >>> >>> Let's suppose my script is like this : >>> >>> CREATE FUNCTION gerachave(INT4) RETURNS INT4 AS' >>> DECLARE >>> CAD ALIAS FOR $1; >>> BEGIN >>> novovalor := 0; >>> >>> UPDATE table1 SET is_ok = 1 WHERE cod_cad = CAD; >>> >>> INSERT INTO cnfg_gerachave VALUES (<quantity of tuples affected by >>> UPDATE>); >>> >>> RETURN CAD; >>> END; >>> ' >>> LANGUAGE 'plpgsql'; >>> >>> >>> Is it possible to discovery how many tuples were affected?
