Hi guys, I have a problem with a sipmle function in postgresql. The func()
calculates two integers to a result and returns it. The result is in the DB,
but not in the Console Line in C#. So for example when i have par1 = 2 and
par2 = 5 I get an DB entry with 7 in the result row, but the ConsoleLine is
empty.
What is wrong here?
BEGIN Result := par1 + par2; insert into t1 (par1, par2, res) values (par1, par2, Result); RETURN Result;
END;$BODY$ LANGUAGE plpgsql VOLATILE COST 100;
ALTER FUNCTION test_func(integer, integer) OWNER TO "Test";
*****************************
c#:
.....
DbParameter giveBack = cmd.CreateParameter(); giveBack.DbType = DbType.Int32;
giveBack.ParameterName= "Result"; giveBack.Direction = ParameterDirection.ReturnValue;
cmd.Parameters.Add(giveBack);
cmd.Parameters["par1"].Value = 2; cmd.Parameters["par2"].Value = 11;
connection.Open();
if (connection.State == System.Data.ConnectionState.Open) {
Console.WriteLine(cmd.Parameters["par1"].Value); Int32 result = cmd.ExecuteNonQuery();
Console.WriteLine("Status: {0}: Result: {1}", result,
cmd.Parameters["Result"].Value); }
Console.WriteLine for par1 returns 2. Console.Writline for Result returns
nothing.
