I am trying to select some with lock and use select for update with where clause. Should I check in my service that this where actually worked? I mean, is this right order?
- Raw is selected using where clause
- Waiting for lock (in another transaction raw changed and where clause is wrong now)
- Acquire lock and return rows
And how can I check this behaviour?
CodePudding user response:
The query is guaranteed to return only rows that satisfy the WHERE
condition.
