MySQL temp table issue
I'm trying to use temp tables to speed up my MySQL 4.1.22-standard database and what seems like a simple operation is causing me all kinds of issues. My code is below....
CREATE TEMPORARY TABLE nonDerivativeTransaction_temp (
accession_number varchar(30),
transactionDateValue date)
) TYPE=HEAP;
INSERT INTO nonDerivativeTransaction_temp
VALUES( SELECT accession_number, transactionDateValue
FROM nonDerivativeTransaction
WHERE transactionDateValue = "2010-06-15");
SELECT *
FROM nonDerivativeTransaction_temp;
The original table (nonDerivativeTransaction) has two fields, accession_number (varchar(30)) and transactionDateValue (date).
Apparently I am getting an issue with the 开发者_如何学运维first two statements but I can't seem to nail down what it is. Any help would be appreciated.
Drop the VALUES(
in INSERT INTO ... VALUES ( SELECT
, it's either VALUES() or SELECT, not both.
And normally this setup of yours would slow down things rather then speed them up unless you're querying the temporary table a LOT during the session, and query-caching is off and/or not feasible.
A quick look makes me wonder if the mismatched parens might be part of your problem...
