you have shown the SP and the exception, that is fine; yet you didn't show the calling code, where the problem could well be... :)

If I were you, I would try to initialize my
OdbcCommandobject instead of just changing the command text :OdbcCommand cmd;
string commandText;try
{
cn.Open();commandText = "use userdb";
cmd = new OdbcCommand(commandText, cn);
cmd.ExecuteNonQuery();commandText = "DROP PROCEDURE IF EXISTS add_emp";
cmd = new OdbcCommand(commandText, cn);
cmd.ExecuteNonQuery();commandText = "CREATE TABLE emp (empno INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, first_name VARCHAR(20), last_name VARCHAR(20), birthdate DATE)";
cmd = new OdbcCommand(commandText, cn);
cmd.ExecuteNonQuery();commandText = "CREATE PROCEDURE add_emp(" +
"IN fname VARCHAR(20), IN lname VARCHAR(20), IN bday DATETIME) " +
"BEGIN INSERT INTO emp(first_name, last_name, birthdate) " +
"VALUES(fname, lname, DATE(bday)); END";
cmd = new OdbcCommand(commandText, cn);
cmd.ExecuteNonQuery();
}... and so on in your second try block. Everytime I tried to reuse a command object to do anything else than its original goal, I ran into troubles. Initiliaze it with
newand see what happens.No memory stick has been harmed during establishment of this signature.

sorry I looked over it. your parameters have identifiers staring with ?, your SQL doesn't use '?' at all. I doubt that is correct. BTW: always look at (and show us) the full exception (i.e. exception.ToString), not just the one-line message. :)

Sooo, overall, your creating a table to hold employee data, which is usually a permanent table in a database, and creating the stored procedure to add an employee to this table, AND calling the procedure to add an employee to this table, ALL IN ONE METHOD?? Your database should be created at install-time, not runtime. Your code should only be calling the stored procedure. I have to ask why you're doing it this way??

Dave KreskowiakActually the thing is I am testing it...I am developing mysql query browser. so when i am calling sp at run time then also i m getting same error...so i have searched on net c# code for calling sp..and i have got this code but when i implemented this then it throws the same error.....

I looked again at your code, and now I'm wondering maybe something is wrong about the bday type (DATETIME,DATE) and the DATE function; so I'd recommend you leave it out till you get the SP working, then add it back in and fix it if necessary. Note 1: I also saw your first Con.Open() was commented... Note 2: and you do check the SP for existence before creating one, but not the table itself. :)
