ORA-12726: unmatched bracket in regular expression
Synopsis
You have mismatched square brackets in your expression. Apply the
advice we give for ORA-12725, but this time look at your use of
square brackets. Also, while an expression such as
'[a
' will cause this error, an expression such as
'a]
' will not, because a closing (right) bracket
is treated as a regular character unless it is preceded by an opening
(left) bracket.
