Question

EDIT:

The table is GIGANTIC! I could just make the backup, and try it locally, if it went fine i could replicate the same on the server, but as i said, the database has almost 500mb, it is indeed quite big. Thanks to those who helped me 🙂

I’d like to change the values from the column “inside_position” where the cell values is 0

update TABLE_NAME SET inside_position=100 where inside_position=0;

I can’t mess this up, so I’ll not set up the trial and error method for this one.

Hope you can help me.

|Product_ID||Product_Code||Inside_position|
|   403    ||   EH009KP  ||       0       |
|   503    ||   GHSJSKD  ||       0       |
|   603    ||   KANSDAS  ||       1       |
|   703    ||   KJNKANS  ||       0       |
|   803    ||   KJHEERF  ||       0       |
|   903    ||   NBVDHQE  ||       5       |
|   910    ||   PKMRQEM  ||       0       |
|   980    ||   990KMNJ  ||       0       |
-------------------------------------------

This table describes my problem, I want to change the ones with 0 to 100.

The code you posted is fine?

 update TABLE_NAME SET inside_position=100 where inside_position=0

If you’re worried about it not working, why not just duplicate the data into a dummy table and then run the query on those, that way you know for sure it will work 🙂
