Gets or sets a Transact-SQL statement or stored procedure used to update records in the data source.
Assembly: System.Data (in System.Data.dll)
During Update, if this property is not set and primary key information is present in the DataSet, the can be generated automatically if you set the SelectCommand property and use the SqlCommandBuilder. Then, any additional commands that you do not set are generated by the SqlCommandBuilder. This generation logic requires key column information to be present in the DataSet. For more information, see Generating Commands with CommandBuilders.
For every column that you propagate to the data source on Update, a parameter should be added to InsertCommand, UpdateCommand, or DeleteCommand.
The SourceColumn property of the parameter should be set to the name of the column. This indicates that the value of the parameter is not set manually, but taken from the particular column in the currently processed row.
