Excuse my complete ignorance of SQL.
I am converting a mysql DB to postgres.
Mysql defines keys in the Create table structure like:
create table ohead (
custid varchar(8),
key orderid (orderid),
.....
To covert this to postgres I guess I need an index, which is done
externally to the create table?
:
create table ohead (
custid varchar(8),
orderid (orderid),
...
CREATE INDEX orderid(??use same name or _idx??) on ohead (orderid);
Again, I am clueless to SQL, how do I utilize the increase in speed?
Does it happen when I SELECT/JOIN things together? or do I reference the
index in my queries.
Thanks!
