    GetUpdateCommand(String[],Boolean) Method
    In This Topic
    Gets the automatically generated SQL statement required to perform updates on the data source when an application calls System.Data.Common.DbDataAdapter.Update() on the ZohoBooksDataAdapter.
    Syntax
    'Declaration
     
    Public Overloads Shadows Function GetUpdateCommand( _
       ByVal fields() As String, _
       ByVal useColumnsForParameterNames As Boolean _
    ) As ZohoBooksCommand
    public new ZohoBooksCommand GetUpdateCommand( 
       string[] fields,
       bool useColumnsForParameterNames
    )

    Parameters

    fields
    Defines list of columns that are allowed to update.
    useColumnsForParameterNames
    Determines whether names of parameters in command text will be based on columns' names.

    Return Value

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

    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().

    useColumnsForParameterNames argument determines whether names of paramerters in command text will be like ":p1", ":p2" (if false), or names of columns will be used (if true), like ":mycolumn1", ":myothercolumn".

    fields argument defines list of columns that are allowed to update. Columns not included into the list will not be updated.
