在 bash 脚本中将链接到 sqlplus 的多个操作更改为 for 循环

Question

I have this script which is obviously inefficient:

#!/bin/sh
for i in $(seq 1 10);
do
  echo "CREATE TABLE testbenny_$i (id NUMBER NOT NULL);
  ! sleep 10
  select * from testbenny_$i;
  ! sleep 10
  select * from testbenny_$i;
  ! sleep 10
  select * from testbenny_$i;
  ! sleep 10
  select * from testbenny_$i;
  ! sleep 10
  DROP TABLE testbenny_$i;" | sqlplus system/passwd &
done

I have one repetitive action I tried to enclose in a FOR loop but couldn't.

  select * from testbenny_$i;
  ! sleep 10

I can't find the correct syntax to change it to a FOR. Working on Oracle 12.

Try the oracle sleep method as following:

#!/bin/sh
for i in $(seq 1 10);
do
  echo "CREATE TABLE testbenny_$i (id NUMBER NOT NULL);
  sys.DBMS_SESSION.sleep(10);
  Begin
  For var in 1..4 loop
  select * from testbenny_$i;
  sys.DBMS_SESSION.sleep(10)
  End loop;
  End;
  /
  DROP TABLE testbenny_$i;" | sqlplus system/passwd &
done

I have given just an example of how to use sys.DBMS_SESSION.sleep(10) method. Use it in your code according to your requirement.
