DbCommandBuilder.GetUpdateCommand Method (Boolean)

Gets the automatically generated DbCommand object required to perform updates at the data source, optionally using columns for parameter names.

Namespace:  System.Data.Common
Assembly:  System.Data (in System.Data.dll)

member GetUpdateCommand : 
        useColumnsForParameterNames:bool -> DbCommand

Parameters

useColumnsForParameterNames
Type: System.Boolean

If true, generate parameter names matching column names, if possible. If false, generate @p1, @p2, and so on.

Return Value

Type: System.Data.Common.DbCommand
The automatically generated DbCommand object required to perform updates.

An application can use the GetUpdateCommand method for informational or troubleshooting purposes because it returns the DbCommand object to be executed.

You can also use GetUpdateCommand as the basis of a modified command. For example, you might call GetUpdateCommand and modify command text, and then explicitly set that on the DbDataAdapter.

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

The default behavior, when generating parameter names, is to use @p1, @p2, and so on for the various parameters. Passing true for the useColumnsForParameterNames parameter allows you to force the DbCommandBuilder to generate parameters based on the column names instead. Generation of the parameters based on column names succeeds only if the following conditions are met:
