Using this tables, please provide me with the screenshot of codes using my SQL : Open four terminal sessions.
1.1. In the first terminal, set the isolation level to read uncommitted.
1.2. In the second terminal, set the isolation level to read committed.
1.3. In the third terminal, set the isolation level to repeatable read.
1.4. In the fourth terminal, set the isolation level to serializable.
Perform insert, delete, update, and select operations on the s, p, j, and spj tables.
When all four terminals are executed simultaneously, display a schedule with a dirty read in a screen dump (refer to textbook cases). Specify which combination (1, 2, 3, or 4) of terminals shows the dirty read.
When all four terminals are executed simultaneously, display a schedule with a non-repeatable read in a screen dump (refer to textbook cases). Specify which combination (1, 2, 3, or 4) of terminals shows the non-repeatable read.
When all four terminals are executed simultaneously, display a schedule with a phantom read in a screen dump (refer to textbook cases). Specify which combination (1, 2, 3, or 4) of terminals shows the phantom read.
When two terminals are set to serializable, T1 attempts to increase the qty of spj by 10%, and T2 simultaneously tries to decrease the qty supplied by s1 by -10. Capture the execution states of the two terminals and submit them.
