Hi Kamal,
I would like to configure it in such a way that if I implement the SELECT statement, another user can't insert
a data into the table.
If it is possible, I even the LOCK would like in such a way to configure the fact that the entry of the user arrives into the buffer and if the table is unlocked, all lines from the Buffer again into the table.
I make it in such a way:
SQL Script script_test.sql:
set echo off
set verify off
set pagesize 0
set termout off
set heading off
set feedback off
lock table mytable in share row exclusive mode;
spool c:\Temp\script_info.lst
select id||'|'||dae||'|'||name||'|'||name1||'|'||hiredate
||'|'||street||'|'||nr||'|'||plznum||'|'||city
||'|'||email||'|'||telephon||'|'||cddfeas||'|'||number
||'|'||why||'|'||fgldwer||'|'||wahl||'|'||adress
||'|'||las
from mytable
where las is null
spool off
spool c:\Temp\select_from_all_tables.lst
select *
from all_tables
order by owner
spool off
spool c:\Temp\select1_from_all_tables.lst
select *
from all_tables
order by owner
spool off
update mytable
set las = 'x';
commit;
set feedback on
set heading on
set termout on
set pagesize 24
set verify on
set echo on
Afterwards I start another session:
insert into briefwahl
values(38,'11.06.2003 09:37','Test','Test','01.01.1990',
'Test','12','90000','Test',
'[email protected]','12345657','test','123',
'test','test','test','test',
null);
Then I go into the first session and start script. And I go immediately into the second session and do commit; And although I have the table closed, the new entries are spent also with spool into the .lst-File. Why, I do not understand. And in the table all lines become updated.
Regadrs
