condition_de_recherche in user_constraints

Hello!

I would like to know how to do a select statement as follows:

SELECT * FROM USER_CONSTRAINTS WHERE SEARCH_CONDITION = 'PASS BETWEEN 0 AND 15';

I'm using Oracle 11 g Enterprise Edition Release 11.2.0.2.0.

If you can afford some time waiting for the result, you can use this:

select *
from xmltable(
      '/ROWSET/ROW'
      passing dbms_xmlgen.getXMLType('select constraint_name, search_condition from user_constraints where search_condition is not null')
      columns constraint_name  varchar2(30)   path 'CONSTRAINT_NAME'
            , search_condition varchar2(4000) path 'SEARCH_CONDITION'
     )
where search_condition = 'my string'
;

invalid column user_constraints

Hi all

What is the use of invalid, View_related columns in the user_constriants table. Can you tell me an example.

Select invalid, View_related from user_constraints;

I can give an example of "view_related" but I can't reproduce anything related to the column "invalid."

Need to retrieve the names of columns with PK

Hi all

guys I need to get two columns (PK information and secondly with the column name) for the table. I see that's not so easy with Oracle ;(

I have this for now:

SELECT all_tab_cols.column_name,user_constraints.constraint_type
FROM   all_tab_cols, user_cons_columns, user_constraints,user_ind_columns, user_indexes
 WHERE  all_tab_cols.column_name = user_cons_columns.column_name (+)
   AND  all_tab_cols.table_name = user_cons_columns.table_name (+)
   AND  user_cons_columns.constraint_name = user_constraints.constraint_name (+)
   AND  user_constraints.constraint_type (+) = 'P'
   AND  user_ind_columns.column_name (+) = all_tab_cols.column_name
   AND  user_ind_columns.table_name (+) = all_tab_cols.table_name
   AND  user_indexes.uniqueness (+) = 'UNIQUE'
   AND  user_indexes.index_name (+) = user_ind_columns.index_name
   AND  all_tab_cols.table_name = 'MYTABLE'

but, if KP is then take result duplicate me lines and there is not a simpler way? just need to list all columns of the table with information about the PK

SELECT acc.column_name,
  ac.constraint_name
FROM all_constraints ac,
  all_cons_columns acc
WHERE ac.owner        =acc.owner
AND ac.constraint_name=acc.constraint_name

UNION
SELECT column_name,NULL FROM all_tab_columns WHERE table_name='MY_TABLE';

Large partition table with the primary key referenced by several child tables

I tested this procedure and it works perfectly. Although when children tables refer to the key column, after execution of dbms_redefinition.finish_redef_table they all are referring to table exercised. In test I deal forced FK droped on tables children and recreated them. What could be the best way to do this in this scenario?
Thanks for all comments/opinions!

Are you sure? You should end up with the original FK constraint (disabled and renamed to have a prefix of $$ TMP) pointing to the staging table (which is of course the famous original table), and allowed a new constraint with the correct name, pointing to the new version of the table. so all you need to do to bring order to the top is to remove the constraint of renamed.

This running-in of the SCOTT schema clearly indicates:

create the table deptint in select * from dept where 1 = 2;

exec dbms_redefinition.start_redef_table (user, 'dept', 'deptint')

n number of var

exec dbms_redefinition.copy_table_dependents (user, "dept', 'deptint', DBMS_REDEFINITION.") CONS_ORIG_PARAMS, TRUE, TRUE, TRUE, TRUE,: n)

Print n

Create procedure upsert (name of the existing table, incoming table name)

Is it possible to create a procedure that makes a merge (upsert) with only two parameters:
1. Existing Table name - name of table that will have data merged into it.
2. Incoming Table name - name of the table that has developed data day/news.
The method would be:
1. Use primary keys on the "existing" table as the condition links
2. Fact and update if exists and insert new
3. no record
4. no clues
5. no removal clause

Online syntax to create Foreign key with Alter Table statement

I am a pretty meticulous reader. That being said, from the 4 texts that I read to start to learn SQL, I do not remember and do more that probably not, find a syntax online for the creation of a CF with the statement alter table.
Just something I thought while I was reading.
Is there a such syntax?
And if so someone can give me direction on my code?
ALTER table emp4 change employee_id key foreign employees of references (employe_id);
It gives me the option error invalid alter table.
Any idea would be appreciated.
Thank you.

The script that creates the table is:

)
;
ALTER TABLE FA_SITES_NEW ADD)
CONSTRAINT FA_SITES_NEW_CHK
CHECK (validdate_from < = validdate_to));
Now the problem is - except that the constraint appears several times(let's leave it for now) - replacement is not done.
In other words, the constraint is "validdate_from < = validdate_to ' and I want to be replaced as FA_SITES_NEW.validdate_from < = FA_SITES_NEW.validdate_to (that's why I use l_str: = replace (l_str, l_allCols (i) .c_name, p_prefix | l_allCols (i) .c_name);).
Instead, the chain remains validdate_from < = validdate_to.
I also tried to do the replacement in a sql stmt ' select replace (l_str, l_allCols (i) .c_name, p_prefix |)» "l_allCols (i) .c_name) in double l_str", but to no avail.
Is it possible this minor change to the result?
NOTE: I use oraDb 11.2.
Thank you very much
SIM

I don't understand. Why do you want to include the name of table to the columns that are used inside the check constraint? This will make the invalid constraint if you rename the table. It seems much better to have the name of the column without a name to additional table.

The problem could be that the expression within the constraint uses lowercase column names, while your system column names select uppercase letters in the data dictionary. This is why replacing is not picking up the names.

id_aa number (1).
id_bb number (1).
descr varchar (20));
ALTER table z
Add constraint z_pk key (aa) primary;
ALTER table z
Add constraint z_fk1 foreign key (id_aa)
references a (aa);
ALTER table z
Add constraint z_fk2 foreign key (id_bb)
references b (aa);
So, I want to choose the names of the tables in such an order so as
deleting records will succeed...
I built the following sql query (using the recursive subquery factoring):
[p]
with q (r_constraint_name, table_name, constraint_name, lvl) as
(select table_name, constraint_name, r_constraint_name 1 lvl
from user_constraints one
where a.constraint_type = 'P '.
Union of all the
Select b.table_name b.constraint_name, b.r_constraint_name, q.lvl + 1 lvl
from user_constraints b
Join q
on (q.constraint_name = b.r_constraint_name)
where b.constraint_type = 'R '.
)
Select f.table_name, f.constraint_name, f.r_constraint_name, f.lvl
q f
[/ p]
I want the results as the following list:
Table-name
----------------
B2
A2
Z
A
B
C
The table - B2, A2, Z - (in any order) must first referred in the list
because they are based on the other three tables - A, B, C. Thus, in order to remove the
A, B, C table records the B2, A2, table Z records must be beleted first.
The query I posted above has the problem that it displays tables A2, B2 twice
(1 because they have a pk and 2 because they have fk referring A, B relatively tables).
Is there a solution for this problem?
Note: I use db11g v2
I wrote not all relationships of tables user_constraints (only argument constraint_name = r_constraint_name)
Thank you

I have a requirement to remove the records from the tables in the order according to

the existing foreign keys.

. . .

The table - B2, A2, Z - (in any order) must first referred in the list

because they are based on the other three tables - A, B, C. Thus, in order to remove the

A, B, C table records the B2, A2, table Z records must be beleted first.

Is there a solution for this problem?

Yes - the 'solution' is to use ON DELETE CASCADE, as appropriate or write a procedure that removes tables in the proper order.

The solution is NOT to try to use dynamic sql statements to do so.

You already know the good parent/child relationships. Simply create a procedure that uses the correct order.

Analyses are necessary in any case to determine the proper order AND press the appropriate values to use to remove the appropriate lines

Your DDL for tables and constraints must be in a version control system

Update the procedure when / if new constraints or tables are added to the application

IMHO, you must use dynamic SQL NOT to try to adjust automatically if a new constraint appears. New constraints should not appear by accident - they appear ONLY as part of a well planned release.

Need help with Ora-00001: constraint Unique voilated in catalog synchronization

Hi Experts...
Has got some problem in the catalog... desperately need help...
Oracle: 11 GR 2
Here is a detail of the error.
from full resynchronization of the recovery catalog
RMAN-00571: ===========================================================
RMAN-00569: = ERROR MESSAGE STACK FOLLOWS =.
RMAN-00571: ===========================================================
RMAN-03009: failure of command resync to the default channel on 26/11/2013 18:01:34
ORA-01403: no data found
ORA-00001: unique constraint (DNKF_GRIP. BRL_U1) violated
========================++++++++++++++++=========================
Kind regards

Hei,

Cool... I have also encountered this kind of error long back... Follow and fortunately we it will be solved.

A problem with the constraint or the Index after the upgrade of the catalogue in 11 GR 2

Remove the constraint, if available, otherwise check index, if found the drop... Rest is history...

First, check the BRL_U1... It can be constrained or an index on the catalog database.

May be it's problem... the compulsion was abandoned during the catalog migration process, but the corresponding index has not been abandoned.

The catalog DB:

-Removal of the index

SQL > connect rman.

SQL > select * from user_constraints where constraint_name = "BRL_U1";

SQL > select * from user_indexes where index_name = "BRL_U1";

SQL > drop index BRL_U1;

Once it will be deposited now connect to the production database to connect to the catalog and re-synchronize... It should work like that...

RMAN target / catalog rman/password@catalog_db_name

RMAN > catalog resync;

from full resynchronization of the recovery catalog

full complete Resync

RMAN > exit

======================================

Kind regards

Need to request so that the data dictionary

Hi all

I need an application that can show all the details of the tables in my database

request to see the... : table name, type of name of column data, constraints, default value, etc...

I found two tables in the database that showa all this information... Here are the 2 quiries:

Select table_name, column_name | » ('|| DATA_TYPE | (' ('| data_length |')) "column_name from all_tab_columns

where OWNER = "UBSPROD."

Select constraint_name, constraint_type, table_name, search_condition_vc, index_name

From user_constraints where owner = "UBSPROD";

but when I join them I get a lot of records... I mean I think he's going to cartiantion products

I used query below:

	Select at.table_name, at.column_name \|' ('\| at.data_type \|') ('\|\| at.data_length\|\|')) "column_name,
	UC.constraint_name, uc.constraint_type, uc.table_name, uc.search_condition_vc, uc.index_name from all_tab_columns to, uc user_constraints
	where at.owner = 'UBSPROD. '
	and at.table_name = uc.table_name

Please, help me to display information with all tables of database related...

Thank you

The reason you see too many lines is because one table lists columns and a list of constraints and want to join the table name. So if you have a table with 3 constraints and 5 columns, you get 15 lines, which probably makes no sense.

Have a reflection on what data you actually want to display for each table. There is a many-to-many relationship between columns and constraints (each column can contain zero or more constraints, each constraint can use more than one column), is without doubt better to keep the two separate, for example

COL1

COL2

COL3

COL4

COL5

CONSTRAINT1

CONSTRAINT2

CONSTRAINT3

This would be achieved either with two separate queries, or you can use a UNION ALL operation, as appropriate. If you want to display the columns used in a constraint, you must query the synonym ALL_CONS_COLUMNS.

Also, make sure you are compatible by using the ALL_ or synonyms USER_ - do not mix the two.

question about how to combine the two scripts.

I have another script that allows to display the newly created tables (table, table names) in the last 24 hours.
SET SERVEROUTPUT ON;
DECLARE
CURSOR tmp_cur IS
SELECT master, object_name
FROM dba_objects
WHERE object_type in ('TABLE', 'SEE') and the owner not in ('SYS', 'SYSTEM', 'GENERAL', "XDB", "OUTLN", "SYSMAN") and last_ddl_time > sysdate - 1;
tmp_rec tmp_cur % ROWTYPE;
BEGIN
FOR tmp_rec IN tmp_cur LOOP
DBMS_OUTPUT. PUT_LINE)
tmp_rec. Owner | ' ' || tmp_rec.object_name);
END LOOP;
END;
/
The gap of the first script (validate_table.sql) is that it can only check table one by one by manual entry, then how can I combine these two scripts, to make a scipt that can check all newly created tables (not a table) in the last 24 hours?
I thank very you much in advance!

Hello

If you already know how to find the owner and all the tables created table_name recently. One thing you can do is to change all the WHERE clauses in validate_table.sql, so instead of things like

where object_name = upper ('& table_name') and owner = upper('&owner');

you say

WHERE (owner, object_name) IN

(

SELECT master, object_name

FROM dba_objects

WHERE object_type in ('TABLE', 'SEE')

AND owner NOT IN ('SYS', 'SYSTEM', 'GENERAL', "XDB", "OUTLN", "SYSMAN")

AND last_ddl_time > SYSDATE - 1

)

;

Here is another approach:

Validate_table. SQL is quite handy as it is. You may want to run this script for tables, even when you know that they are not new. Divide into 2 scripts: one called ask_and_describe_table.sql, which looks like this:

-Ask_and_Describe_Table.sql

accept invites owner "Enter table owner:

accept invites from TABLE_NAME "Enter object (table/View...) "name:"

-You can use any name path instead of d:\some_dir below:

@d:\some_dir\describe_table & owner, table_name

and the other one called Describe_Table.sql, which starts like this:

-Describe_Table.sql

DEFINE owner = & 1

DEFINE table_name = & 2

column owner format a10 column 'owner '.

...

and continues with the same exact content as validate_table.sql.

Now, to write another script (I'll call it Describe_Recent_Tables.sql):

-Describe_Recent_Tables.sql - create and run Describe_Many_Tables.sql

-Turn OFF the devices designed to help people to read the output:

SET ECHO OFF

SET FEEDBACK OFF

SET PAGESIZE 0

VERRIFY OFF SET

-Create a Describe_Many_Tables.sql:

COIL d:\some_dir\describe_many_tables.sql

SELECT ' @d:\some_dir\describe_table '

||      owner

||      ' '

||      object_name

FROM dba_objects

WHERE object_type in ('TABLE', 'SEE')

AND owner NOT IN ('SYS', 'SYSTEM', 'GENERAL', "XDB", "OUTLN", "SYSMAN")

AND last_ddl_time > SYSDATE - 1;

SPOOL OFF

-Features lighting designed to help people to read the output:

SET ECHO ON

SET FEEDBACK ON

SET PAGESIZE 50

SET VERRIFY ON

-Describe_Many_Tables.sql performance

@d:\some_dir\describe_many_tables

I guess that all of your tables have standard names (for example, start with a letter, no spaces in the name,...), which don't require quotation marks. If they could, then the same basic approach will work, but the details are a little messier.

When you want to see the information on a single table or view, no matter how old it is, driven

Ask_and_Describe_Table

or, if you do not need to question the owner of the table and the name, something like

Describe_Table SCOTT EMP

(You can find that you really need not Ask_and_Describe_Table.sql).

When you want to do this for all the tables created in the last 24 hours:

Describe_Recent_Tables

Generate the Sql Data model ER diagram

Hello
I want to use the Oracle Sql Developer Data Modeler to generate ER diagram for my schema. There are a lot of tables in this schema, so I would like to exclusively identify the tables that should be selected to generate my ER diagram.
Basically, I want these table that are related to other tables here. The reason being, if I select all the tables in the schema, and then I went to these tables in the ER diagram which have nothing to do with other tables.
Please can anyone suggest write queries that produce this data dictionary?
Thank you.
```
select uc1.constraint_name,
       uc1.table_name,
       uc1.constraint_type,
       uc2.constraint_name,
       uc2.table_name,
       uc2.constraint_type
from   user_constraints uc1,
       user_constraints uc2
where  uc1.constraint_type='R'
       and uc1.r_constraint_name=uc2.constraint_name
```
This gives you the relationship between the primary and foreign key

condition_de_recherche in user_constraints
