I'm having trouble getting a CallableStatement to work with the
following function
CREATE OR REPLACE FUNCTION pro_register_cookie_for_user(
prmUserId int8,
prmSecureGuid varchar,
OUT outUsernameHash varchar,
OUT outMaxAge float4)
AS $$
...
$$ LANGUAGE plpgsql;
The function works fine over pgAdmin, so I think the problem lies in
the Java code.
callable = conn.prepareCall("{call pro_register_cookie_for_user(?, ?, ?, ?)}");
callable.setLong(1, playerId);
callable.setString(2, secureGuid);
callable.registerOutParameter(3, Types.VARCHAR);
callable.registerOutParameter(4, Types.FLOAT);
callable.executeQuery();
String usernameHash = callable.getString(3);
float maxAgeF = callable.getFloat(4);
When running this on Java 1.5, pgsql-jdbc 8.1.404 and Postgres 8.1, I
get the following error:
A CallableStatement function was executed and the return was of type
java.sql.Types=12 however type java.sql.Types=0 was registered.
at org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2Statement.java:380)
at org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:250)
Can anyone shed some light on what I'm doing wrong?
Cheers
Michael

Having followed Adam's advice and prevented the original error by
upgrading the Jar to
8.1-407, I now get a different exception. For the same function:
CREATE OR REPLACE FUNCTION pro_register_cookie_for_user(
prmUserId int8,
prmSecureGuid varchar,
OUT outUsernameHash varchar,
OUT outMaxAge float4)
AS $$
...
$$ LANGUAGE plpgsql;
I now get the following error:
org.postgresql.util.PSQLException: No results were returned by the query.
at org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:259)
This is caused by the AbstractJdbc2Statement.executeWithFlags(int)
method returning false for any code path which satisfies the condition
(isFunction && returnTypeSet).
This appears to be at best mis-reported as I can clearly see the
results being read into the abstractJdbc2Statement.callResult
instance variable.
Is this right?

TIP 2: Don't 'kill -9' the postmaster
Gents,
My apologies, this one is my fault. In attempting to circumvent the
original problem I was experimenting with different ways of calling
the procedure, and had left my own code as running
statement.executeQuery() instead of statement.execute().
