How to use Regular Expression in sql server?

Question

Is it possible to make efficient queries that use regular expression feature set.I got data in my table which is not in correct format,EX:-In Title colum: Cable 180â

Answer 1

You need to make use of the following. Usually requires combinations of the three:

1. patindex
2. charindex
3. substring

In response to your comment above, patindex should not 0 where the case is found. patindex finds the start location of the pattern specified, so if patindex finds the case, it should return an integer > 0.

EDIT:

Also, len(string) and reverse(string) come in handy on specific occasions.
