Question

I have following table

ID | Name | Url

Each Url contains address to file fe: “http://blah.blah.com/abcde.bin”. Address is always same but file name. In need SQL query to update all cells in this column, where Url contains http and store only file name.

Example:

SELECT URL FROM TABLE

1 | "http://blah.blah.com/abcde.bin"

UPDATE ...

SELECT URL FROM TABLE

1 | "abcde.bin"

Answer 1

Try this query:

UPDATE TABLE SET URL = REPLACE(URL ,'http://blah.blah.com/','')

it doesn’t use contain or substring, but does the same, with less code. If it finds the 'http://blah.blah.com/' string, it will be replaced with an empty string, so you will have just your name.

I didn’t try it but I think it’s correct.

Hope it helps you.
