SQL & PL/SQL :: Copying Data From Table (with No Constraints) To Table With Constraints?
Jun 13, 2012I want to create a store procedure to copy data from a source tables(which may not have any constraints defined) to a table which has primary key, foreign key and unique key constraints.
Any records which are rejected due to these constraints not being satisfied need to go another table.
Once the initial data load is done, these procedures need to be automated(through cron) to do the future incremental uploads in the same manner.

How To Lock Statistics In Column Level
Jul 4, 2012i am using 10.2.0.1.0 version of oracle.
I have gathered frequency histogram manually on one of my column of a table to provide more information to optimizer for better calculation of cardinality.

I don't want to lock the statistics of whole table, but i just want to lock the column level stats for this table.

SQL & PL/SQL :: How To Disable Or Enable All Constraints In A Table
Apr 8, 2010I knew, how to enable or disable a constraint on a table.
>alter table <table_name> disable constraint <constraint_name>;
But if we know all the data is correct, it's better to disable all constraints to improve the performance.
We are allowed to Disable or Enable only a single constraint.

View 7 Replies View RelatedServer Administration :: How To View Table Constraints Information
Mar 13, 2010I know that you can view all constraints in a table using $USER_CONSTRAINTS or $USER_INDEXES view. What i find difficult is that the information in those views is not really well presented.
I find it very hard to follow. For example, just to find out which columns are foreign keys and which tables they refer to is really tedious. Is there a simpler way to view all the constraints especially foreign keys of a table and including which table columns they refer to in the child table.
I like to see a diagramatic representaion of all the tables involved so i like to see both the parent and the child tables, which columns are related and using which FKs etc. is there an easier way to view this information?

SQL & PL/SQL :: How To Get Difference Between Two Rows Of Same Column
Aug 3, 2013Calculating the difference between the two rows of same columns? Example of my Scenario is as follows
I have a table as shown below, there are checks thats has been issued per week (to tell how its been issued per week ,if you see the week number ,there is a change in week no for period of 7 days i.e. what i have to show on my results tables based on week no and probably we may need to take into account for check no too.)
wekno ! checkno ! end date
------ ! ------ ! ------
1 ! 1 ! 1/7/2012
1 ! 2 ! 1/8/2012
1 ! 3 !1/9/2012
2 ! 1 ! 1/14/2012
2 ! 2 ! 1/15/2012
3 ! 1 ! 1/21/2012
result table and date range i picked up was 1/1/2012-1/31/2012
wekno ! checkno ! end date ! previous period ! Daysin period
------ ! ------ ! ------ ! ------------- ! ------------
1 ! 1 ! 1/7/2012 ! null (as previous period is 2011 and so prvs year i dont count) ! 7 this because we see change in wkno per 7 days
1 ! 2 ! 1/8/2012 !null becoz this one falls same week and therefore previous peroid would be the same as above ! 7 above reason
1 ! 3 ! 1/9/2012 ! null becoz this one falls same week and therefore previous peroid would be the same as above ! 7 above reason
2 ! 1 ! 1/14/2012 ! 1/7/2012 becoz this a second week as you see the change in wekno and therefore its previosu period is 1/7/2012 ! 7 above reason
2 ! 2 ! 1/15/2012 ! 1/7/2012 becoz this check falls on the same second week so previosu would be 1/7/2012 ! 7 above reason
3 ! 1 ! 1/21/2012 ! 1/14/2012 as a new week no starts this gonn be 1/4/2012 ! 7 above reason

Security :: Auditing At Table Level In 11g?
Apr 27, 2012We have recently upgraded our DR environment from 9i to 11g. We have auditing turned on for 3 tables.

Below is the sql statement we used to turn on auditing on these tables.
audit select,update,delete on audit_Test2 by session;
Opened SR with Oracle, but no proper response from them...
what changes we need to do in order to reduce the amount of audit data on these tables in 11g?
