Home -> Community -> Mailing Lists -> Oracle-L -> RE: Longest SQL statements!!!
Murali:
The only issue that I know of is in Oracle that the SQL statement must be less than 64K. I've written 3-page SQL statements that returned in the sub-0.1 second range.
However, from a human standpoint, the longer the SQL is, the harder it is for a new developer to pick up and tune/debug/tweak/etc. In general, I try to keep my SQL to under 1/2 page. But I DO NOT sacrifice readability in order to keep my SQL Under 1/2 page. Most of the time, when I'm asked to tune or debug a SQL statement, my reformatted, revised SQL winds up being longer than the original -- but much easier for a human to read -- reformatting it makes it easier for me to tune or correct.

Are there any implications on how long the SQL statement is? The current SQL
statements that I am inheritting, is really long. tons of embedded sub queries etc.
My first question is are there any known issues with haveing very long SQL statements and if yes what has been a good length other than the fact that it may depend on your SGA.
Thanks
Murali
