DB2 Column Compare Tool





            Whenever, we are working in Datawarehouse / Database (Oracle / MSSQL / DB2) projects, we often need to compare to tables column wise. When such requirement comes, we might end up in confusion putting the columns list in the excel sheet and comparing each column by column.

              Here’s procedure you can create in your local DB and run it feeding it with Tables names as input, and in one run you get three outputs: Matched columns, Table1 unmatched columns, table2 unmatched columns. You might need to give schema name of Table if there are two tables in SYSCOLUMNS with the same name.




You can modify or re-write the same procedure for your respective DBs.
