Gets or sets the Transact-SQL statement, table name or stored procedure to execute at the data source.
Assembly: System.Data (in System.Data.dll)
When the CommandType property is set to StoredProcedure, the property should be set to the name of the stored procedure. The user may be required to use escape character syntax if the stored procedure name contains any special characters. The command executes this stored procedure when you call one of the Execute methods.
The Microsoft .NET Framework Data Provider for SQL Server does not support the question mark (?) placeholder for passing parameters to a Transact-SQL statement or a stored procedure called by a command of CommandType.Text. In this case, named parameters must be used. For example:
SELECT * FROM dbo.Customers WHERE CustomerID = @CustomerID
