SQL & PL/SQL :: Copying Data From Table (with No Constraints) To Table With Constraints?

Jun 13, 2012

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.

Remove Constraints On Nested Table?

Jul 11, 2011

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.

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.

Server Administration :: How To View Table Constraints Information

Mar 13, 2010

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?

SQL & PL/SQL :: Create Complete Hierarchical Table From Table With Only Two Columns - Parent And Child

Aug 13, 2012

We have a table in the client database that has two columns - column parent and column child. The whole hierarchy of DB table dependencies is held in this table.If Report 1 is dependent on Table A and Table A in turn is dependent on two tables Table M and Table N. Table N is dependent on table Z it will appear in the db table as,

Hierarchy Table
Parent Child
Report1Table A
Table ATable M
Table ATable N
Table NTable Z

Requirement :

From the above structure, we need to build a table which will hold the complete hierarchy by breaking it into multiple columns.The o/p should look like this

-ParentChild 1Child 2 Child 3
-Report1Table ATable M
-Report1Table ATable N Table Z

Child 1, Child 2, Child 3 ....and so on are columns.The number of tables and the no of hierarchical relationships are dynamic.

SQL Statements to create hierarchy table:

create table hierarchy (parent varchar2(20), child varchar2(20));
insert into hierarchy values ('Report1','Table A');
insert into hierarchy values ('Report1','Table B');
insert into hierarchy values ('Table A','Table M');
insert into hierarchy values ('Table B','Table N');
insert into hierarchy values ('Report2','Table P');
insert into hierarchy values ('Table M','Table X');
insert into hierarchy values ('Table N','Table Y');
insert into hierarchy values ('Report X','Table Z');

Approached already tried :

1) Using indentation : select lpad(' ',20*(level-1)) || to_char(child) P from hierarchy connect_by start with parent='Report1' connect by prior child=parent;

2)Using connect by path function :
select *
from (select parent,child,level,connect_by_isleaf as leaf, sys_connect_by_path(child,'/') as path
from hierarchy start with parent='Report1'
connect by prior child =parent) a where Leaf not in (0);

Both the approaches give the information but the hierarchy data appears in a single column.Ideally we would like data at each level to appear in a different column.

Truncate / Drop Partitions In Table Having Nested Table Columns

Sep 7, 2012

I have a table that has 2 columns of type nested table. Now in the purge process, when I try to truncate or drop a partition from this table, I get error that I can't do this (because table has nested tables). how I will be able to truncate/drop partition from this table? IF I change column types from nested table to varray type, will it work?

Also, is there any short method of moving existing data from a nested table column to a varray column (having same fields as nested table)?

All Columns Of A Table Are Part Of Primary Key Column Of That Table?

Feb 22, 2011

if a table contains two columns and both are part of the primary key of that table (Kind of obvoius).

should i opt for a index organized tbale in this case ?Or should i opt for another running sequential colum which would serve as a primary key of this table and define the actual two columns of the system as unique keys.

there is a drawback if a most of the tables of a database contain composite primary keys?

Performance Tuning :: Update Columns Of One Table Using Another Table

Feb 6, 2011

I am trying to update columns of Table A with the columns of Table B. Both these tables have 60,000 rows each. I tried this operation using following 2 queries:

Query 1

Update TableA A
set
(A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3
from TableB
where A.CODE=B.CODE)

Query 2
Update TableA A
set
(A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3
from TableB
where A.CODE=B.CODE)
where exists
A.code = (select B.code
from TableB B
where A.code=B.code)

When i execute these two above queries, it keeps executing indefinitely.

Append Columns From One Table To Another

Nov 14, 2011

Perhaps this is a common request : I have 2 tables:

Table A
-------
ID Value
1 a
2 b
3 c

Table B
-------
ID AnotherValue
1 x
2 y

I am hoping to append a column from Table B to Table A based on a simple sql join (e.g:

Table A

ID Value AnotherValue
1 a x
2 b y
3 c (null)

)

I would rather stay away from the standard update statement since it takes far to long and I'd prefer not to use create table as I don't want to duplicate any data...is this possible to do ? (e.g: just insert the columns into this table ?) - or if it's possible the performance overhead just wouldn't make it worth it ?

Joining Two Columns In Same Table?

Jan 30, 2007

We have a table for reports. If user A submits a report ...and say the sequence # is 242. When this report goes to Admin ...he submits this request then in same table we add another row with say sequence # 245. THEN we update column called 'Asctd ID' for 242 and add 245 in there. and then update Asctd ID for 245 and add 242 in there.

(This table has many fields, one of which is report Name field)

Now i am running a query like this...

SELECT b.JOB_ID, a.DESC, TO_CHAR(a.CREATE_DATE,'MM/DD/YYYY'),
DECODE(a.DLVRY_TYPE,'','PDF',a.DLVRY_TYPE), DECODE(a.FLG,'','N/A',
a.FLG), ((TO_DATE(a.CREATE_DATE,'DD-MON-YY')) + 21) -
TO_DATE(SYSDATE, 'DD-MON-YY'), c.STATUS_DESC, a.SIZE_NUM,
b.PRVDR_ID, a.asctd_id, d.NM
FROM REQUEST_DIM a, PROVIDER_DIM b, STATUS_DIM c, DIM d
WHERE a.FLAG = 'P' and RTRIM(a.RPT_RQST_USER_ID) = 'TEST02' AND a.RPT_RQST_TYPE = 'D'
AND a.RPT_RQST_ACTIVE_IND = 'A' and a.asctd_id is not null and a.RPT_RQST_ID = b.RPT_RQST_ID
and b.JOB_ID = c.JOB_ID and b.PRVDR_ID = d.PRVDR_ID
AND c.CREATE_DT = (SELECT MAX(d.CREATE_DT)
FROM STATUS_DIM d
WHERE d.RPT_RQST_ID = b.RPT_RQST_ID and d.JOB_ID = b.JOB_ID )
ORDER BY a.RPT_RQST_ID, a.CREATE_DATE

Now this query is run by the admin (job 245) ...it returns a bunch of stuff and also the name of the report that the admin gave this. But when admin sees this we want to be able to displace the report name that user A gave it (asctd ID 242). so the row 245 HAS a asctd ID 242. and there is a row 242 from which we can get the name easily. But i dont know if this is possible in ONE QUERY??

Search All Columns In A Table

Jan 15, 2009

I have an application which deploys the data to Oracle database. It has more than 25 tables and many columns. It does not have any document explaining the deployment, so I am kind of doing reverse engineering here.

I need a script which will fetch the column name or at least table names which will match with either some string or number? I found few examples on net to find out number. But I am struggling to make it work for string.

I can not work on stored proc, as I do not have access to create that on server. So, any script will work.
