Barry Lind,
function:
create function testfunc() returns void language sql as 'update table1 set col1=0';
Test.java:
...
CallableStatement stmt = null;
try
{
stmt = conn.prepareCall("{call testfunc()}");
stmt.executeUpdate();
}
catch(Exception e)
{
System.out.println(e.toString());
}
...
output:
java.sql.SQLException: ERROR: Unknown kind of return type specified for function testfunc
I checked the jdbc code, and find this in AbstractJdbc1Statement::modifyJdbcCall(string):
if (connection.haveMinimumServerVersion("7.3")) {
l_sql = "select * from " + l_sql + " as " + RESULT_ALIAS + ";";
} else {
l_sql = "select " + l_sql + " as " + RESULT_ALIAS + ";";
}
I changed "7.3" to "7.4" here. And then the error became : A result was returned when none was expected.
