I have created two tables in pgAdmin database with the same type of informations. That is the number of column and line are the same and the columns names are also the same, just the inforamtions in the tables are sometimes different(see the excel files in attachement).
I want to compare contract number i of table1 with contract number i of table2 using tmap. For example compare contract 1 in table1 with contract 1 in table 1.
