Dear Sirs,

I am spending about 10 hours on little problem: to pass a parameter (text) to a PostgreSQL (v. 8.1 on Win2000). The

relevant code is:

java side:

private CallableStatement cs;

cs = conn.prepareCall(INSERT_CONGRESSO);

cs.setString(1, itemCongresso.getCongresso()); //return a String

cs.execute();

...

public static final String INSERT_CONGRESSO = "{SELECT ins_congressoa(?)}";

PostreSQL side:

CREATE OR REPLACE FUNCTION ins_congressoa(congresso text)
RETURNS void AS
$BODY$INSERT INTO "Congressi" ("Congresso") VALUES ($1)
$BODY$
LANGUAGE 'sql' VOLATILE;
ALTER FUNCTION ins_congressoa(congresso text) OWNER TO postgres;

With Pgadmin the function work fine, but from java program does not. WHY?

Thank you.

Domenico

You're mixing your calling syntax.  You need to write either:

conn.prepareCall("{ ? = call ins_congressoa(?)}");

or

conn.prepareStatement("SELECT ins_congressoa(?)");
