Q&A
| Q1: | If I have a group of transactions and one transaction is unsuccessful, will the rest of the transactions process? |
| A1: | No. The entire group must run successfully. |
| Q2: | After issuing the COMMIT command, I discovered that I made a mistake. How can I correct the error? |
| A2: | Use the DELETE, INSERT, and UPDATE commands. |
| Q3: | Must I issue the COMMIT command after every transaction? |
| A3: | No. But it is safer to do so to ensure that no errors were made and no previous transactions are left hanging. |
