    GetDeleteCommand(Boolean) Method
    In This Topic
    Gets the automatically generated SQL statement required to perform deletions when an application calls System.Data.Common.DbDataAdapter.Update(System.Data.DataSet) on the System.Data.IDbDataAdapter.
    Syntax
    'Declaration
     
    Public Overloads Shadows Function GetDeleteCommand( _
       ByVal useColumnsForParameterNames As Boolean _
    ) As DbCommand
    public new DbCommand GetDeleteCommand(

    )

    Parameters

    useColumnsForParameterNames
    Determines whether dotConnect uses columns metadata to make up parameters' names. If true, the names are composed using colon and name of appropriate column; otherwise the names look like :p1, :p2 etc.

    Return Value

    A DbCommandBase with CommandText containing SQL statement to be executed.
    Remarks
    You can use the GetDeleteCommand() method for informational or troubleshooting purposes because it returns the DbCommandBase object to be executed.

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

    After the SQL statement is first generated, you must explicitly call DbCommandBuilderBase.RefreshSchema if it changes the statement in any way. Otherwise, the GetDeleteCommand() 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(System.Data.DataSet) or GetDeleteCommand().
