The main difference is that Tomi needs to have automatic criteria
applied to every query he makes. Ie, a "WHERE time between
effectivestart and effectiveend" for every select, insert, and update.
What I need, and what Eric sounds like he needs, is for an AUDIT_LOG
record to be created for every insert, update, and delete. Actually
one for every field changed in an insert or update.
For example, here's what the fields of an audit record look like for
me (xml definition).
<?xml version="1.0" ?>
<table>
<column java.sql.Types="4" keyOrder="1" name="ID" nullable="false"
position="5" primaryKey="true" type="INTEGER" />
<column java.sql.Types="12" keyOrder="0" name="SCHEMA_NAME"
nullable="true" position="11" primaryKey="false" size="32"
type="VARCHAR" />
<column java.sql.Types="12" keyOrder="0" name="TBL_NAME"
nullable="true" position="13" primaryKey="false" size="32"
type="VARCHAR" />
<column java.sql.Types="12" keyOrder="0" name="COL_NAME"
nullable="true" position="1" primaryKey="false" size="32"
type="VARCHAR" />
<column java.sql.Types="12" keyOrder="0" name="MOD_TYPE"
nullable="true" position="7" primaryKey="false" size="1"
type="VARCHAR" />
<column java.sql.Types="12" keyOrder="0" name="OLD_VALUE"
nullable="true" position="9" primaryKey="false" size="2000"
type="VARCHAR" />
<column java.sql.Types="12" keyOrder="0" name="NEW_VALUE"
nullable="true" position="8" primaryKey="false" size="2000"
type="VARCHAR" />
<column java.sql.Types="4" keyOrder="0" name="FOREIGN_KEY"
nullable="true" position="4" primaryKey="false" type="INTEGER" />
<column java.sql.Types="12" keyOrder="0" name="FKEY_CONDITION"
nullable="true" position="3" primaryKey="false" size="200"
type="VARCHAR" />
<column java.sql.Types="93" keyOrder="0" name="MOD_TIME"
nullable="true" position="6" primaryKey="false" size="6"
type="TIMESTAMP" />
<column java.sql.Types="4" keyOrder="0" name="SYSTEM_ID"
nullable="true" position="12" primaryKey="false" type="INTEGER" />
<column java.sql.Types="4" keyOrder="0" name="EFFECTIVE_USER_ID"
nullable="true" position="2" primaryKey="false" type="INTEGER" />
<column java.sql.Types="4" keyOrder="0" name="REAL_USER_ID"
nullable="true" position="10" primaryKey="false" type="INTEGER" />
</table>
ID is meaningless primary key
SCHEMA_NAME.TBL_NAME.COL_NAME describes path to data changed.
MOD_TYPE is insert, delete, or update (I,D,U)
OLD_VALUE and NEW_VALUE are the state changes.
FOREIGN_KEY and FKEY_CONDITION are references to the record that was
changed (FK_C is for compound keys, FK is for a single integer key).
MOD_TIME is when the record was changed.
SYSTEM_ID/EFFECTIVE_USER_ID/REAL_USER_ID describes where the data was
changed. (application and user).
