Question

Does anybody know how to use apex item in apex_util.json_from_sql in application process when we try to find a value between two number? My query just like this one below :

SELECT  
ID , locn_x lat, locn_y lon
FROM database where locn_x between :P1_SEBOUNDLAT and :P1_NWBOUNDLAT

But it’s return no result. Apex item :P1_SEBOUNDLAT and :P1_NWBOUNDLAT has a value cos i diplay it and i try to do query in database and give me result. it seem : without = become a problem in this query. Because when i try to query

where locn_x > :P1_SEBOUNDLAT 

it give me an error

Please somebody give me an advice.

Answer 1

According to your comment you are executing this:

APEX_UTIL.JSON_FROM_SQL(
  'SELECT ID ,locn_x lat, locn_y lon FROM table where locn_x between '
|| wwv_flow.g_x05
|| ' and '
|| wwv_flow.g_x03
|| )');

And getting a “missing expression” error because of that last bit, which is missing a quote (‘):

|| ')');
