Parametri

sqlCommands
Tipo: System.Collections.Specialized.StringCollection
A StringCollection system object value that specifies the batches of Transact-SQL statements to be executed.

Valore restituito

Tipo: array<System.Int32[]
An Int32 array value that specifies the total number of rows affected by each element of the StringCollection object used as the sqlCommands parameter. The return value 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

Executes batches of Transact-SQL statements that typically do not return result sets. These are typically data definition language (DDL) statements or stored procedures that affect the server settings.

The Text property of the CapturedSql object can be used as a parameter to allow execution of captured Transact-SQL statements.

The StringCollection object used as the sqlCommands parameter can contain several batches separated by the batch separator. By default, the batch separator is GO, but can be set with the BatchSeparator property. Batch execution is controlled with the executionType parameter.

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.

'Iterate through the strings in the capture buffer and display the captured statements.
Dim s As String
For Each s In srv.ConnectionContext.CapturedSql.Text

Next
'Execute the captured statements.
srv.ConnectionContext.ExecuteNonQuery(srv.ConnectionContext.CapturedSql.Text)
'Revert to immediate execution mode.
