Data Locking in Oracle Development

Oracle development tool PL/SQL is a powerful tool for Oracle development and use. At the same time, Oracle is intended for users. A single user role may be used by multiple people at the same time. It is common in group development. Operations on data, such as update, insert, and delete operations, follow the principles of transactions. After the preceding operations on data are performed, commit must be submitted, the transaction is not completed. If other users want to modify the data or perform other operations on the data, they will wait until the transaction is completed before the result is returned.
That is to say, the Appeal data will be locked. WhenProgramWhen the data operation is called, it will wait, waiting for the data to be unlocked, and waiting for no response will take a long time and will crash.
Therefore, when using the Oracle database to operate data, you should promptly commit it to complete data transaction operations and release key data in a timely manner.
