Bug Regexp and sed problem
Basically it should identify what ever is in between /*< >*/ (tags) and replace dbname ending with (.) with the words in between the tags

i.e.

Code:
    DELETE FROM /*<workDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1 ALL; into 
    
    
   DELETE FROM /*<workDB>*/${workDB}./*<multi>*//*<version>*/${multi}${version}_epd_tbl1 ALL;

one more example

Code:
       DELETE FROM /*<abcDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1 ALL; into 
       
       
   DELETE FROM /*<abcDB>*/${abcDB}./*<multi>*//*<version>*/${multi}${version}_epd_tbl1 ALL;

what I was thinking was to remember /*< as pattern 1 i.e \(\/\*<\) and workDB as one more pattern >*/ as one more pattern and identify until the
period and replace as above? Is this doable

and similarly for dates it replace with in the single quotes with out using from_dt










sample.sql contains:
Code:
 
DELETE FROM /*<workDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1 ALL;

 
INSERT INTO /*<workDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1
SELECT
  *
FROM
  /*<finDB>*/epd_fin.pr_tbl
WHERE
      (   epd_dt >= cast(/*<from_date>*/'2007-01-01' as date)
      AND epd_dt < cast(/*<to_date>*/'2009-09-14' as date)
      )
  OR  (   epd_cre_dt >= cast(/*<from_date>*/'2007-01-01' as date)
      AND epd_cre_dt < cast(/*<to_date>*/'2009-09-14' as date)
      )
      
    ;

output should be:

Code:
 
DELETE FROM /*<workDB>*/${workDB}./*<multi>*//*<version>*/${multi}${version}_epd_tbl1 ALL;

INSERT INTO /*<workDB>*/${workDB}./*<multi>*//*<version>*/${multi}${version}_epd_tbl1
SELECT
  *
FROM
  /*<finDB>*/${finDB}.pr_tbl
WHERE
      (   epd_dt >= cast(/*<from_dt>*/'${from_dt}' as date)
      AND epd_dt < cast(/*<to_dt>*/'${to_dt}' as date)
      )
  OR  (   epd_cre_dt >= cast(/*<from_dt>*/'${from_dt}' as date)
      AND epd_cre_dt < cast(/*<to_dt>*/'${to_dt}' as date)
      )
      
    ;


Thanks in advance
