Re: Compare two sources column by column

i have two inputs that i need to combine them through tMap and insert data in an Oracle database , so my problem is that the two sources may not come with the same number of columns each time (one missed column maybe) , though they are supposed to be the same. is there a way to check automatically for the differences between the two sources. 

thank you for your help.

Hi @TalendNew ,

If your inputs are files then talend has a component called tfilecompare which can be used to compare 2 different files or same files in your case.

If your inputs arent files and you are pulling 2 tables instead from a database then you have sql builder option wherein you can check the structure of the tables and the columns/fields inside them.

Pls get back to the community, if necessary.
