In MySql:
DELIMITER //
DROP PROCEDURE IF EXISTS `testdb`.`Check_UserId_Sproc` //
CREATE PROCEDURE `testdb`.`Check_UserId_Sproc` (IN User_Id NVARCHAR(100))
BEGIN
select count(*) from demo_user where userid = User_Id;
END //
DELIMITER ;
In C#:
public DataTable ExecuteParameterizedSelectCommand(string CommandName, CommandType cmdType,MySqlParameter[] param)
{
DataTable table = new DataTable();
string CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
using(MySqlConnection con = new MySqlConnection(CS))
{
using (MySqlCommand cmd = con.CreateCommand())
{
cmd.CommandType = CommandType.Text;
cmd.CommandText = CommandName;
cmd.Parameters.AddRange(param);
try
{
if (con.State != ConnectionState.Open)
{
con.Open();
}
using (MySqlDataAdapter da = new MySqlDataAdapter(cmd))
{
da.Fill(table);
}
}
catch
{
throw;
}
return table;
}
}
}
public DataTable checkExistingUserId()
{
MySqlDBHelper oHelper = new MySqlDBHelper();
MySqlParameter[] parameters = new MySqlParameter[]
{
new MySqlParameter("User_Id", 'DemoId')
};
return oHelper.ExecuteParameterizedSelectCommand("Check_UserId_Sproc", CommandType.StoredProcedure, parameters);
}
When I try to execute the checkExistingUserId() , I get following exception:
Incorrect number of arguments for PROCEDURE testdb.Check_UserId_Sproc; expected 1, got 0
May be I am doing a silly mistake but I am not able to figure it out. I am new to mysql and trying to work around it.
When I debug the array contains the parameter as seen in below image, but it is not collected by the SP.
Thanks in advance
In your code:
cmd.CommandType = CommandType.Text;
should be
cmd.CommandType = cmdType;
