Across the table, please update the value can not be read immediately?
Run for the first time, sheet1. NAME=content. NAME operation. The second will be sheet1 bm=sheet1. NAME
In theory should be done once!
=========the following code=========
The UPDATE sheet1,
The content
The SET sheet1. NAME=content. NAME,
Sheet1. Bm=sheet1. NAME
WHERE
Sheet1. Id=1

CodePudding user response:

For as long as submitted, you can read right now

CodePudding user response:

No, isn't it? Or is reading under the dirty read transaction isolation level

CodePudding user response:

The UPDATE sheet1, content
SET
Sheet1. NAME=content. NAME,
Sheet1. Bm=sheet1. NAME
WHERE sheet1. Id=1

The problem of the original poster actually and
Update t set=a, b, c=b, d=c where id=1 a property, pay attention to the SQL statement execution logic and program code execution logic, such as the differences of logic of c code,
