[Gems-users] how to add magic break point in query?

[Liqun Cheng <liqun.cheng@xxxxxxxxx>]

Hi,

I am wondering how to insert a magic instruction in sql queries. I know we can use sethi to add magic instruction in C programs, now I am running quries in mysql, for exmpale, "mysql database < 1.sql". I'd like to add a magic instruction at the end of 
1.sql, thus I can calculate the execution time of query 1. 

thanks!
