Update decimal precision and indexes in ddl
-------------------------------------------
Key: DAYTRADER-25
URL: http://issues.apache.org/jira/browse/DAYTRADER-25
Project: DayTrader
Issue Type: Improvement
Reporter: Christopher James Blythe
Priority: Minor
While working with previous versions of Trade, I found that the monetary values
stored in the database could overrun the decimal precision defined in the
schema (10,2) if allowed to run for an extended period of time. This would
result in SQL exceptions related to data conversion.
To prevent this we increased the decimal presion to (14,2)
We also found that some of the indexs were not necessary and that others should
be added.
In addition to the primary keys, here are the indexes we found to be the most
useful...
CREATE INDEX a.profile_userid on accountejb(profile_userid);
CREATE INDEX h.account_accountid on holdingejb(account_accountid);
CREATE INDEX o.account_accountid on orderejb(account_accountid);
CREATE INDEX o.holding_holdingid on orderejb(holding_holdingid);
CREATE INDEX o.closed_orders on orderejb(account_accountid,orderstatus);
Will wait to submit a patch until the fate of Daytrader-14 is determined.
