sql_regcasesql_regcase
Description
string sql_regcase (string string)
Returns a valid regular expression which will match string, ignoring case. This expression is string with each alphabetic character converted to a bracket expression; this bracket expression contains that character's uppercase and lowercase form. Other characters remain unchanged.
This can be used to achieve case insensitive pattern matching in products which support only case sensitive regular expressions.
