Hi,

 It fails when we try to open this table in the DB Painter: 

Powerbuilder version:  PB22 R3 Build 3289

Oracle DB Client:              instantclient_19_20

DB Test:

1. Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 – Production Version 19.19.0.0.0
2. Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 – Production Version 19.23.0.0.0

CREATE TABLE "TMP_TABLE_TEST"  (    

                "PKCOL" VARCHAR2(5) NOT NULL,

                "COL1" NUMBER(7,0),

                "COL2" VARCHAR2(10) DEFAULT 'dd/mm/yyyy',

                "COL3" VARCHAR2(1) DEFAULT 'N'

   );

In the DB trace, a query is launched to check the default value of the numeric field and in the condition of said query, it includes the default value ''dd/mm/yyyy'' in double quotes as the table name .

SELECT DATA_DEFAULT FROM USER_TAB_COLUMNS WHERE TABLE_NAME = ''DD/MM/YYYY'' AND COLUMN_NAME = 'COL1'(DBI_DEBUG_MESSAGE) (0.001 MS / 2795.950 MS)
