Hi, I am new to APEX.I buld my first app but my user want to enter numbers with ',' as decimal separator. Creating process before header in master detail form doesn;t help me. BEGIN EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_NUMERIC_CHARACTERS = ",."'; END; When I try to enter 23,45 value in database column is 2345. I do the same thing with sql*plus and I can insert numeric value as: INSERT INTO table VALUES ('23,45',.......); Text field in master detail tabular form onlu accpet numeric values. Thanks!!!
