Abstract: A method for performing a data store operation is provided. The method comprises invoking a command to execute on a processor in a computer that identifies an input file, determining a structure of a data table stored in a database and reading rows of data out of the data table based on the input file. For each row comparing data read out of the data table to a corresponding row of data in the input file. When the row of data read is identical to the corresponding row of data in the input file, not updating the row of data in the data table. When the row of data read is not identical to the corresponding row of data in the input file, updating the row of data stored in the corresponding row of data in the input file based on the structure of the data table.
