exception raised for valid variable declaration?
I do get the following exception when trying to create a new data row in
one of my tables:
System.Data.SqlClient.SqlException: Must declare the variable '@cAttend'
I have the following code:, which deckares the variable within the scope of
execution, so I am kind of confused why this happens. Any help is
char cAttend = 'N';
this.sqlInsertCommand1.CommandText = "INSERT INTO mytable (keyNum,
cAttended) VALUES (131415, @cAttend)";
Re: exception raised for valid variable declaration?
Lookup any article about "parameterized queries". Basically you are
declaring a variable (or: "placeholder"), but you aren't filling the
placeholder. You should add somethin like
this.sqlInsertCommand1.Parameters.Add("@cAttend", myValue); before you
actually execute the query.
