mysql query building output taking a long time
- by user121196
I have a simple query that does select * from t limit 1; on a remote mysql server.
I use squirrel(mysql client) to run it, it shows:
Query 1 of 1 elapsed time (seconds) - Total: 22.047, SQL query: 1.047, Building output: 21
why does building output take such a long time? what does this process do? when running from mysql command line, the whole process takes 0.3 secs (also remotely)
