Update data in a column in table A based on a common column in table B. The fight between the front-end and back-end engineers attracts the attention of the product manager. Update data in two columns in table A based on a common column in table B. What it boils down to is lack of error checking in psql not the backend. A variant on that is to clear the buffer and insert "out of memory" in this scenario, but that's not too pleasant either. If you are using Alibaba Cloud RDS, you may try the writing to combine the update and select statements into an SQL statement, and further reduce the network overhead and database overhead to improve the performance. If you need to update multiple columns simultaneously, use comma to separate each column after the SET keyword. That is to use a variable, put the update result in the variable, and then read out the variable in the same session. In a single-library and single-table database, usually an incremental number is used for our table's primary key, but it cannot be used after horizontal splitting. Instead, it may be subject to another update statement, so that the user can feel the enthusiasm of other users during the period when the database begins to execute the update statement, and during the period when the update statement is executed until the select statement starts to be executed. I checked it on the StackOverflow.
