[SOLVED] SQL.DTDIFF

Has anyone tried to use this SQL function and gotten it to work? I may be doing something wrong but when i try and run it with two valid dates ( i just hard coded them for testing sake) the translated oracle SQL comes back with:

 (FOC1410) SQL COLUMN NOT FOUND. (FOR TABLE: CHECK ALIAS NAMES)
 : ORA-00904: "DTDIFF": invalid identifier
 : Erroneous token: DTDIFF
  


Is there a specific syntax i'm not aware of?

I believe function DB_EXPR has replaced SQL. as the preferred method to pass SQL functions directly to the DB.

I'll have to look DB_EXPR up, not familiar with it. I've use sql.replace in a webfocus report before but this one is throwing me for a loop.

I figured it out, i was under the assumption that these functions required the 'SQL.' prefix in front of them but that is incorrect. So this:

DIFFERENCE_IN_DAYS/I6 = SQL.DTDIFF('&YYMD', SOME_DATE_FIELD, DAY);  


Should have been:

DIFFERENCE_IN_DAYS/I6 = DTDIFF('&YYMD', SOME_DATE_FIELD, DAY);  


Good news is my query got a bit faster with this change.

I believe 8.1.05 has some new streamlined date functions that more closely mirror SQL functions in format and require fewer parameters. Seems I saw that at Summit.
