Adobe QoQ supports MSSQL [] regex char sets in LIKE operator

This SQL returns 1 matching row in MSSQL and Adobe CF QoQ:

Note, MySQL, Oracle, and Postgres do not support square bracket char sets in their LIKE operator.

This has potential backwards compat issues, so we need to also fix the escape character which currently does not work. The default escape char should be "\" and we should also support this syntax which is standard SQL:

Additional information. The square bracket char set works the same as regex. It matches a single character in the set or range of chars defined. Ex:

• [0-9] – Match a single digit "0" through "9"

•  

• – match a single char NOT "x", "y", or "z"
