GG what do you think is the cause of the error of this code below which i used for testing.....
declare
v_alltables varchar2(10000);
begin
for rec in (select TABLE_NAME from all_tables where owner = 'APPS' AND ROWNUM =1)
loop
execute immediate 'SELECT DBMS_METADATA.GET_DDL( '|| '''TABLE'',' ||rec.table_name||',''APPS'') FROM DUAL' into v_alltables;
dbms_output.put_line(v_alltables);
end loop;
end;
it gives this error message when run:
Error report:
ORA-00904: "ADX_PRE_AUTOCONFIG": invalid identifier
ORA-06512: at line 7
00904. 00000 -  "%s: invalid identifier"But when i change the rec.table_name into '''ADX_PRE_AUTOCONFIG''' the code works properly.
so i decided to have this code and it works.
SET SERVEROUTPUT ON
declare
v_alltables varchar2(10000);
begin
for rec in (select TABLE_NAME from all_tables where owner = 'APPS' AND ROWNUM =1)
loop
execute immediate 'SELECT DBMS_METADATA.GET_DDL( '|| '''TABLE'',' ||''''||rec.table_name||''''||',''APPS'') FROM DUAL' into v_alltables;
dbms_output.put_line(v_alltables);
end loop;
end;for you newbie, this must also work
SET SERVEROUTPUT ON
declare
v_alltables varchar2(10000);
begin
for i in (select table_name from all_tables where rownum<2)
loop
execute immediate 'SELECT DBMS_METADATA.GET_DDL( '|| '''TABLE'',' ||''''||i.table_name||''''||',''TRNG8305_GC'') FROM DUAL' into v_alltables;
dbms_output.put_line(v_alltables);
end loop;
end;hope it helps.....
