    GetUpdateCommand(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 MySqlDataAdapter.
    Syntax
    'Declaration
     
    Public Overloads Shadows Function GetUpdateCommand( _
       ByVal useColumnsForParameterNames As Boolean _
    ) As MySqlCommand
    public new MySqlCommand GetUpdateCommand( 
       bool useColumnsForParameterNames
    )

    Parameters

    useColumnsForParameterNames
    Determines whether names of parameters in command text will be based on columns' names.

    Return Value

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

    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".
