Status: Geschlossen |
DB2COMMANDBUILDER.DERIVEPARAMETERS() FAILS TO FIND PARAMETERS FOR STORED PROCEDURES IN IDS ANSI MODE DATABASES |
| Produkt: |
DB2 CONNECT / DB2CONNCT / 970 - DB2 |
| Problembeschreibung: |
If you execute the following example code against an IDS Ansi
mode database, the DB2CommandBuilder.DeriveParameters() call
does not identify any parameters for stored procedures.
reproducible test:
static void IDS_DeriveParameter_From_SP()
{
string connStr =
"database=ansimodedb;server=system:port;uid=myuid;pwd=mypwd;";
String szProcName = "MYPROC2";
try
{
using (DB2Connection tstConn = new
DB2Connection(connStr))
{
tstConn.Open();
DB2Command tstCmd = tstConn.CreateCommand();
tstCmd.CommandText = "drop procedure " +
szProcName + " (INT)";
try
{
tstCmd.ExecuteNonQuery();
}
catch
{
}
tstCmd.CommandText = "create procedure " +
szProcName + " (parm1 INT) INSERT INTO NMP_INTEGER VALUES
(parm1); end procedure";
tstCmd.ExecuteNonQuery();
tstCmd.CommandText = szProcName;
tstCmd.CommandType = CommandType.StoredProcedure;
DB2CommandBuilder.DeriveParameters(tstCmd);
IDataParameterCollection pcol =
tstCmd.Parameters;
IDbDataParameter parm = null;
for (Int32 i = 0; i < pcol.Count; i++)
{
parm = (IDbDataParameter)pcol[i];
Console.WriteLine("Param[{0}]", i);
Console.WriteLine("Name={0}",
parm.ParameterName);
Console.WriteLine("Direction={0}",
parm.Direction);
Console.WriteLine("Type={0}", parm.DbType);
}
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}

| Local-Fix: |
The problem is caused by the DB2 .NET Provider improperly
providing the fully qualified name of the stored procedure
resulting in the procedure not being found. As a work around to
the problem, provide the fully qualified stored procedure name
in the DB2Command.CommandText property. |
