When creating a policy to manage the naming of an object (facet), SQL Management Studio (SMS) allows Expressions to evaluate the Field, e.g. @Name of the facet and requires a Value, which can be written with a regular expression.
This Value seems to allow (based on the Operator which is LIKE, similar to SQL) a kind of regular expression, which I am not able to exhaustively establish. It allows RegEx constructs, but not quite like in .Net, but it also does not seem to be constrained to tSQL pattern matching either.
For example: Using ^\b, denoting start of string or word, fails when evaluating the policy (against the given facet) by failing the evaluation for all objects. Also it likes the expression % instead of \w* and struggles to evaluate (?(expr) yes|no) correctly, I think because I'm bungling the syntax, however...
I have downloaded Expresso (a Regex tool) from Code Project
, in which I'm able to construct the Regular Expression correctly, but it does not work in the Expression Value for the Condition in SQL Server 2008 Policy Based Management.
I am also struggling to obtain specifics on the syntax to use, i.e. the regex building blocks etc.
Can anybody help with some useful reference sites from which to obtain the syntax that's allowed in this functionality of SQL Server 2008.
Your help is appreciated!
