When a transaction acquires a row lock, the transaction also needs to obtain the table lock of the table where the row of data is located. The table lock prevents conflicting DDL operations, that is, the database automatically adds an exclusive lock to the updated row and adds a sub-exclusive lock to the table where the row is located.
Row locks and concurrency
The following uses an example to understand the relationship between row locks and concurrency.
First, create the following table and
data in parallel.
