Here's what that rule is looking for:

On any port of any host designated as a SQL SERVER (in the var in your 
snort.conf file)

content:"|05|"; depth:1; byte_test:2,>,512,1; content:"|3B|"; distance:0; 
isdataat:512,relative; content:!"|3B|"; within:512;

Which translates to:

Enqueue followed by ";" between 2 and 512 bytes later followed by another 
";" within 512 bytes of the previous one with data in between the 
semicolons.  Engueuing is the process of putting items in a queue, which is 
frequently used in databases.

Can you post the payload?

If you have sql servers on your network, you should define them in the 
SQL_SERVERS var in snort.conf.  That will eliminate useless alerts like 
this one.
