I have not had experience in SQL queries or SQL database , so please

  • 0

I have not had experience in SQL queries or SQL database , so please excuse me if my terminology is wrong.

So, I have a file containing around 17,000 SQL insert statements where I enter data for 5 columns/attributes in a database. In those 17,000 statements there are only around 1200 statements which have data for all of the 5 columns/attributes while the rest have data only for 4 columns. I need to delete all those unwanted statements( which dont have data for all 5 columns).

Is there a simple way/process to do it other than going one by one and deleting? If so, it would be great if someone could help me out with it.

    A different approach from my fine colleagues here would be to run the file into a staging/disposable database. Use the delete that @Rob called out in his response to pare the table down to the desired dataset. Then use an excellent, free tool like SSMS Tools Pack to reverse engineer those insert statements.
