MySQL / ASP.NET Stored Procedures - asp.net

Question

Hopefully this is not a ServerFault question...
I'm working forward on migrating a project from storing data in XML Serialization to a MySQL database. I'm using the example provided me from a previous question answered yesterday.
Connecting using phpMyAdmin and MySQL Workbench I've created a Stored Procedure called 'sprocOrderSelectSingleItem'. It seems to work well with MySQL for all I can tell. When I run the SHOW CREATE PROCEDURE sprocOrderSelectSingleItem it returns the following:
CREATE DEFINER=username#% PROCEDURE sprocOrderSelectSingleItem(IN orderID INTEGER)
BEGIN SELECT * FROM tblOrders WHERE ID=orderID; END
My cooperative ASP.NET code goes something like this:
public static Order GetItem(int ID)
{
Order objOrder = null;
using (OdbcConnection objConnection = new OdbcConnection(Utils.ApplicationConfiguration.ConnectionString))
{
OdbcCommand objCommand = new OdbcCommand("sprocOrderSelectSingleItem", objConnection);
objCommand.CommandType = CommandType.StoredProcedure;
objCommand.Parameters.AddWithValue("orderID", ID);
objConnection.Open();
using (OdbcDataReader objReader = objCommand.ExecuteReader())
{
if (objReader.Read())
{
objOrder = FillDataRecord(objReader);
}
objReader.Close();
}
objConnection.Close();
}
return objOrder;
}
When I view the page I get the following error message:
ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.0.77]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'sprocOrderSelectSingleItem' at line 1
Really not catching on to what could be missing or going wrong. Are there any additional tests I should/could be running to confirm things are working on the MySQL side? Am I missing a step to pass the Stored Procedure call correctly in ASP.NET? The code breaks at the line of:
using (OdbcDataReader objReader = objCommand.ExecuteReader())
Replacing the line of
OdbcCommand objCommand = new OdbcCommand("sprocOrderSelectSingleItem", objConnection);
with this instead
OdbcCommand objCommand = new OdbcCommand("SELECT * FROM tblOrders WHERE ID=" + ID + ";", objConnection);
and everything works as expected.
Thanks for any help you guys can provide.

Answer 1

Your can run an execute on sprocOrderSelectSingleItem in Mysql directly with the ID parameter.
It will show that your StoredProc run correctly.
Here is a sample code in C# that call a stored proc.
OdbcCommand salesCMD = new OdbcCommand("{ CALL SalesByCategory(?) }", nwindConn);
salesCMD.CommandType = CommandType.StoredProcedure;
OdbcParameter myParm = salesCMD.Parameters.Add("#CategoryName", OdbcType.VarChar, 15);
myParm.Value = "Beverages";
OdbcDataReader myReader = salesCMD.ExecuteReader();
Look at the "Call" in the OdbcCommand and the "?" for the parameter that is later supplied with a value.

Can you try something like below:
OdbcCommand cmd = new OdbcCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "{call LoadCustCliOrders(?,?,?,?)}";
cmd.Parameters.Add("CUST_ID",OdbcType.Int);
cmd.Parameters.Add("CLIENT_ID",OdbcType.Int);
cmd.Parameters.Add("DATE_FROM",OdbcType.Date);
cmd.Parameters.Add("DATE_TO",OdbcType.Date);
...
cmd.Parameters["CUST_ID"].Value = _CustId;
cmd.Parameters["CLIENT_ID"].Value = _ClientId;
cmd.Parameters["DATE_FROM"].Value = _DateFrom;
cmd.Parameters["DATE_TO"].Value = _DateTo;
cmd.ExecuteReader

Are you sure that you are using the same username or user with the same access privileges.
I think you need to add the word "CALL" before the stored proc.
It should be CALL sprocOrderSelectSingleItem and try.
