but this makes the column default to the time of table creation, not
|
||||
the time of row insertion. Instead do:
|
||||
create table test (x int, modtime timestamp default text 'now');
|
||||
CREATE TABLE test (x int, modtime timestamp default now() );
|
||||
|
||||
The casting of the value to text prevents the default value from being
|
||||
computed at table creation time, and delays it until insertion time.
|
||||
The calling of the function now() prevents the default value from
|
||||
being computed at table creation time, and delays it until insertion
|
||||
time. We believe this will not be a problem in post-6.5.* releases.
|
||||
|
||||
4.23) Why are my subqueries using IN so slow?
|
||||
|
||||
Currently, we join subqueries to outer queries by sequential scanning
|
||||
the result of the subquery for each row of the outer query. A
|
||||
workaround is to replace IN with EXISTS. For example, change:
|
||||
SELECT *
|
||||
FROM tab
|
||||
WHERE col1 IN (SELECT col2 FROM TAB2)
|
||||
|
||||
to:
|
||||
SELECT *
|
||||
FROM tab
|
||||
WHERE EXISTS (SELECT col2 FROM TAB2 WHERE col1 = col2)
|
||||
|
||||
We hope to fix this limitation in a future release.
