For security reasons, our oracle db objects normally belong to a different schema than the logged in user. Eg. tables are in xx_core and the user we log in is xx_app_yy .
In my persistence.xml I define a orm file so that I can specify the schema name at deploy time eg.:
<mapping-file>xx_schema_orm.xml</mapping-file>
Then in the xx_s...
In SQL Server I used the following hints inside queries:
rowlock (row level locking)
updlock (prevents dirty reads)
readpast (don't block waiting for a rowlock, go to the first unlocked row)
e.g.
select top 1 data from tablez with (rowlock,updlock,readpast);
Are there equivalent in-query hints for Oracle?
