ORACLE SQL: Basic help required in script
Hi,

I am having the following codes which generates 24 files:
Code:
 declare
 begin
 for i in 0..23 loop
 EXECUTE IMMEDIATE 'create tablespace TSCGFCDR' ||to_char(sysdate,'DD')||'_'||to_char(i,'fm00')||
 to_char(i+1,'fm00')||to_char(sysdate,'MONYY')||' DATAFILE '||
  '''/ORADATA7/CRESTELDATA/TSCGFCDR'||to_char(sysdate,'DD')||'_'||to_char(i,'fm00')||
 to_char(i+1,'fm00')||to_char(sysdate,'MONYY')||'.dbf''
 SIZE 1M AUTOEXTEND ON NEXT 5M MAXSIZE UNLIMITED EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO';
 end loop;
 end;
 /


Code:
TSCGFCDR10_0001OCT12.dbf  TSCGFCDR10_0405OCT12.dbf  TSCGFCDR10_0809OCT12.dbf  TSCGFCDR10_1213OCT12.dbf  TSCGFCDR10_1617OCT12.dbf  TSCGFCDR10_2021OCT12.dbf

The modulo function should do the trick (untested):
Code:
declare
 begin
 for i in 0..23 loop
 EXECUTE IMMEDIATE 'create tablespace TSCGFCDR' ||to_char(sysdate,'DD')||'_'||to_char(i,'fm00')||
 to_char(i+1,'fm00')||to_char(sysdate,'MONYY')||' DATAFILE '||
  '''/ORADATA7/CRESTELDATA/TSCGFCDR'||to_char(sysdate,'DD')||'_'||to_char(i,'fm00')||
 to_char(mod(i+1,24),'fm00')||to_char(sysdate,'MONYY')||'.dbf''
 SIZE 1M AUTOEXTEND ON NEXT 5M MAXSIZE UNLIMITED EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO';
 end loop;
 end;
 /

Can you please explain how mod fun will work

Old 10-12-2012
mod(a,b) returns the remainder of a devided by b. The Oracle documentation explains it quite simple and Wikipedia gives you deeper insight.

if you want change the file manually.... Try like ..
Code:
sed 's/TSCGFCDR10_2324OCT12/TSCGFCDR10_2300OCT12/g' test.txt
