Namespace: Microsoft.SqlServer.Management.Common
Assembly: Microsoft.SqlServer.ConnectionInfo (in microsoft.sqlserver.connectioninfo.dll)

Syntax

'Declaration
Public Function ExecuteNonQuery ( _
    sqlCommand As String _
) As Integer

public int ExecuteNonQuery (
    string sqlCommand
)

public:
int ExecuteNonQuery (
    String^ sqlCommand
)

public int ExecuteNonQuery (
    String sqlCommand
)

public function ExecuteNonQuery (
    sqlCommand : String
) : int

Parameters

sqlCommand
A String value that specifies the Transact-SQL command to be executed.

Return Value

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.

Remarks

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.

This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.

Example

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Set the execution mode to CaptureSql for the connection.
srv.ConnectionContext.SqlExecutionModes = SqlExecutionModes.CaptureSql
'Make a modification to the server that is to be captured.
srv.UserOptions.AnsiNulls = True
srv.Alter()
'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
    Console.WriteLine(s)
Next
'Execute the captured statements.
srv.ConnectionContext.ExecuteNonQuery(srv.ConnectionContext.CapturedSql.Text)
'Revert to immediate execution mode. 
srv.ConnectionContext.SqlExecutionModes = SqlExecutionModes.ExecuteSql
