GetUpdateCommand() Method

In This Topic

Gets the automatically generated SQL statement required to perform updates on the database when an application calls System.Data.Common.DbDataAdapter.Update() on the UniDataAdapter.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Shadows Function GetUpdateCommand() As UniCommand

public new UniCommand GetUpdateCommand()

Return Value

The text of the SQL statement to be executed.

Remarks

You can use the GetUpdateCommand() method for informational or troubleshooting purposes because it returns the UniCommand object to be executed.

You can also use GetUpdateCommand() as the basis of a modified command. For example, you might call GetUpdateCommand() and modify the CommandText value, and then explicitly set that on the UniDataAdapter.

After the SQL statement is first generated, you must explicitly call Devart.Common.DbCommandBuilderBase.RefreshSchema if it changes the statement in any way. Otherwise, the GetUpdateCommand() still will be using information from the previous statement, which might not be correct. The SQL statements are first generated when the application calls either System.Data.Common.DbDataAdapter.Update() or GetUpdateCommand().

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
