Hi,

I'm using an sql to replace credit card numbers with xxxx and finding that REGEX_REPLACE does not consistently replace everything. Below is the SET command i'm using on the SQL

SET COMMENTS_LONG = 
    REGEXP_REPLACE (COMMENTS_LONG,'\D[1-6]\d{3}.\d{4}.\d{4}.\d{3}(\d{1}.\d{3})?|\D[1-6]\d{12,15}|\D[1-6]\d{3}.\d{3}.?\d{3}.\d{5}', ' XXXXXXXXXXXXXXXX')

Before

Elizabeth aclled to change address.5430-6000-2111-1931 A

After

Elizabeth aclled to change address XXXXXXXXXXXXXXXX1 A

I tried increasing the number of X but result is the same. I also find that i have to put a space in front of the first X as it appears to move 1 char to the left.

I am writing a tool to help students learn regular expressions. I will probably be writing it in Java.

I need to be able to check for a pattern with | in them. For example an expression like d*|*t should return true for a string like "dtest|test".
