Question

I don’t think this is possible as I couldn’t find anything but I thought I would check on here in case I am not searching for the correct thing.

I have a settings table in my database which has two columns. The first column is the setting name and the second column is the value.

I need to update all of these at the same time. I wanted to see if there was a way to update these values at the same time one query like the following

UPDATE table SET col1='setting name' WHERE col2='1 value' AND SET col1='another name' WHERE col2='another value';

I know the above isn’t a correct SQL format but this is the sort of thing that I would like to do so was wondering if there was another way that this can be done instead of having to perform separate SQL queries for each setting I want to update.

Thanks for your help.

Answer 1

I decided to use multiple queries all in one go. so the code would go like

UPDATE table SET col2='value1' WHERE col1='setting1';
UPDATE table SET col2='value2' WHERE col1='setting1';

etc
etc

I’ve just done a test where I insert 1500 records into the database. Do it without starting a DB transaction and it took 35 seconds, blanked the database and did it again but starting a transaction first, then once the 1500th record inserted finish the transaction and the time it took was 1 second, so definetely seems like doing it in a db transaction is the way to go.
