[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

It appears in MySql 3.23 the limit is 16 MB.  In 4.0 and later, it is 1 GB

Could someone tell me where I can find PostgreSQL doc about the query length please
Tks a lot!

Hello,

Just curious to know whether postgresql has any length constraint about where part, such as


Query =
[
select col1, col2, ... coln
from table 1, table2,
where

constraint1 + constraint2 +................................constraintN
]

Is there any length arrange for the Query str such as 500M, 1G, etc? Or the query can be as long as it is.

Thanks a lot!
