Can someone can tell me a nice approach to checking how, and where, parenthesis

  • 0

Can someone can tell me a nice approach to checking how, and where, parenthesis may be missing (or be in excess) in a query such as the following?

For example, this query returns error that it is missing right parenthesis. But where??? !

SELECT * FROM ( SELECT X.*, ROWNUM AS RN FROM (SELECT ORG_UNIT, QUEUE_NAME, CASE_STATUS, AGENT_ROLE, COUNT(*) AS CASE_COUNT 
   FROM

    Crimson Edit and many other text editors and IDEs have brace matching.

    http://en.wikipedia.org/wiki/Crimson_Editor

    If brace match, but are nested wrong, you may need to change your indentation strategy.

    Also, code formatting tools sometimes can make it clear where you missed a paren or nested wrong.

    Here is one online place where you can paste in your code to see it reformatted.
