Question

I have a large table with ZIP codes but they are in long format like : 06608-1405

What I require is to REMOVE the hyphen and the numbers after the hyphen. I have using MYSQL REPLACE before but not sure how if you can use Wildcards.

Cheers for you time.

Answer 1

How about using SUBSTRING_INDEX:

select SUBSTRING_INDEX(ZIP, '-', 1);

Edit:

To update the table:

Update <table-name> set ZIP = SUBSTRING_INDEX(ZIP, '-', 1);
