On 2018-03-20 at 02:03:45, an sql error occured. When asked the trouble, the database said:

"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-5, 5' at line 1"

The error was thrown from in the function and the offending sql statement is below:

select * from tbl_postjob where 1 and fld_status='1' and fld_jobId in (134,135,136,317,318,638) order by fld_mod_date desc limit -5, 5
