SQL & PL/SQL :: How To Disable Or Enable All Constraints In A Table
Apr 8, 2010
I 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.
Enable or Disable All Constraints.

In PL/SQL Plus, i can enable/disable auditing when i connect as sysdba by using these command:
SQL> ALTER SYSTEM SET audit_trail=db SCOPE=SPFILE
SQL> shutdown
SQL> startup
I've done it successfully with PL/SQL Plus command line. But in PHP, how can i do that?How to execute "shutdown" and "startup" from PHP?
I've found this code for connect to oracle as sysdba:
oci_connect("/", "", null, null, OCI_SYSDBA);
From the following link:
[URL]......
But, i still can't execute "shutdown", "startup";

I have one tabular block on the canvas and there is one check box on this block. I want that when I uncheck this checkbox, one item on the current record gets disabled.
i manage to turn all the records enabled or disabled.
I am attaching a dummy form in which I have tried. Checkbox is acting on field :ecc_no.
The DB table for the same is:
CREATE TABLE ECC_MASTER
(
PARTY_TYPE CHAR(1 BYTE) NOT NULL,
PARTY_CODE CHAR(5 BYTE) NOT NULL,
ECC_NO VARCHAR2(25 BYTE) NOT NULL,
RANGE_DIVISION VARCHAR2(30 BYTE),
EMP_NO NUMBER(4) NOT NULL,
[code]....

I have a master-detail form showing multiple records (tabular) in data-block. Now my problem is, based on certain column's value of a particular item in a particular row on the data-block to ENABLE/DISABLE during run-time .
For example, in a detail-block of 5 rows, if 3rd row's 'detail-block.item1' is equal to lets say, "X", then 'detail-block.item2' of that particular row ONLY must be 'disabled'. otherwise, it must 'enable' the 'detail-block.item2' of that particular item in that particular row on the data-block.
Even when, I query the form, it must enable/disable that particular item of that particular row from the data-block based on item1's value.

I have a Select list which when null should disable a button and when not null should enable it. For which I tried the Advanced DA. Strangely, in the final page where we select the item that is going to be controlled, the button is not listed! I can see other display items etc which I can select but not the button.

I 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.

I want to truncate table partition but I'm getting error:
CODEORA-02266: unique/primary keys in table referenced by enabled foreign keys
because of table has a nested table. Currently this column is not in use so I could drop it, but I want to avoid it (table is huge). Is there another posibility to do truncate partitions in this table? ALTER TABLE ... SET UNUSED doesn't resolve the problem.

I 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?
