Does the mysql UNION and UNION ALL operator always remove rows that have a NULL in them? I am doing a UNION of two SELECT statements - one of which may return a row with a NULL in it. When it does, it does not include that row in the UNION. Is there a way around this?
Union select null, null, null, null, null, null, null from information_schema.tables. for a small database containing three tables. this instruction is used in sql injection I tried it and it worked but I didn't really know how it works can somebody help me...
