Subj:   Re: Process to identify orphaned views
 
From:   Stieger, Etienne E

Hi Anomy,

Yes, we have a process to check for invalid views. I have embedded the text of 2 files in this mail.

Keep in mind that the shell script is possibly using other functions and shell scripts which you would need to create alternatives for. It would not be practical to share all of our code base with you. Our original intention was to automatically retry compiling invalid views, but we have decided not to for specific reasons.


     "viewlist_startpoint.sql":
     width 15000;
     SELECT TRIM(t_VWS.DATABASENAME)||';'||
             TRIM(t_VWS.TABLENAME)||';'/*||
             TRIM( TRAILING FROM t_VWS.RequestText)*/ "Record"
     FROM DBC.TABLES t_VWS,
          (select CHILD
           from DBC.CHILDREN
           where PARENT='PROD') t_DBS
     WHERE t_VWS.TABLEKIND = 'V'
     AND   t_VWS.DATABASENAME = t_DBS.CHILD
     /*AND   TRIM(t_VWS.TABLENAME) = 'M_CCP_CUST_V'
     */ORDER BY 1;
