Implementing Queuing Mechanism

By Harsha Majety,

Insert rows in to the queue table and run this script in the queue processor job.

 

 

Table Hints do the trick ,otherwise there will be locking issues.

 

UPDLOCK : Grabs an update lock until transaction is completed and prevents another process from picking up same queue item.

 

READPAST : If a process encounters a row that is currently locked by another, this hint will make it skip that locked row and moves on to find the next one.
