Parametri
- sqlCommand
Tipo: String
A String value that specifies the Transact-SQL command to be executed.
Valore restituito
Tipo: Int32
An Int32 value that specifies the total number of rows affected by the Transact-SQL command for UPDATE, INSERT, and DELETE statements. For all other types of statements, the return value is -1.
Osservazioni
The Transact-SQL command is typically a data definition language (DDL) statement or stored procedure that affects the server settings. The Text property of the CapturedSql object can be used as the sqlCommand parameter to allow execution of a captured Transact-SQL statement. The sqlCommand parameter contains a single Transact-SQL statement.
Only SQLCMD commands are recognized by the ExecuteNonQuery method. If the sqlCommand parameter contains a statement that is not a SQLCMD command then the method fails and an ExecutionFailureException exception is raised.
