What do you mean it "refers to two different tables"? If you store value from two tables in the same column, rethink your design. Also, you didn't really try anything, write an SQL query, see what works and what not and ask help with that.

I meant if that column is referred in multiple tables, so that means its a foreign key there and there would be , lets say 4 primary key equivalent to it in 4 different tables. So Need a SQL Query in MYSQL TO delete a value from a column in the table where it is foregin key

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

has been a while for me but.. try something like this:

DELETE FROM table1 t1, table2 t2
WHERE t1.id = 1 AND t2.parent_id = t1.id

Please let know if this method works, i am not 100% sure
