SQL & PL/SQL :: Get Row Counts Of Tables In Schema Without Using Num_rows
Aug 9, 2010
I am trying to get a row count(*) for all the tables in my schema. The NUM_ROWS column in DBA_TABLES is not appropriate in this case because they are as good as the last analyze. So I need to get real time counts.
I tried the following code but I can't seem to catch my error.
DECLARE
l_sql varchar2(150);
cursor tablelist is
select table_name from dba_tables where owner = 'ME';
[Code]....
My expected results are :
TABLE_NAME ROW_COUNT

SELECT COUNT(*) FROM APP.Big_table; Number of record--222653402
This is a big table to get the it's taking 8 minutes time, so that I tried the following SQL to get the count quickly.
SELECT num_rows FROM all_tables WHERE table_NAME='BIG_TABLE'
and owner='APP'; --Number of records 237213998
But I got the different count for the two SQLs. Why there is a difference in the count. Which one is correct.

Our stats are collected at the schema level as follows:
EXEC DBMS_STATS.gather_schema_stats('schema', estimate_percent => 15, degree => 8 )
However, when I compare the num_rows in user_indexes to the num_rows in user_tables, for some indexes I am getting zero rows but over 100k rows in the table.I can see from the last_analyzed col on user_indexes that stats were gathered within seconds of the stats being collected on the tables.

I have created 2 different databases and each have their own schema user for eg we have database ALIVE with user allive and the other database RLIVE with user rllive , actually we have implemented new module in ALIVE database and in the process we created many tables , synonyms , index and other objects now we want to list out all the tables ,sequences as scripts which are not present in RLIVE and create them in RLIVE as new objects.

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit
i'm trying since some hours to get information from inside a trigger from another table of the same schema.My trigger table is PSE_BKB.NUM_PHANTOM_BP
First i tried simple solution ...
CREATE OR REPLACE TRIGGER PSE_BKB.NUM_TR_PHANTOM_BP
BEFORE DELETE OR INSERT OR UPDATE
ON PSE_BKB.NUM_PHANTOM_BP
REFERENCING NEW AS NEW OLD AS OLD
[code]...
The last version i tried was with a cursor definition inside the trigger as in the code-block below.For debugging purposes i've inserted a RAISE_APPLICATION_ERROR in the inner loop - see below. The variable v_obj_key is never set, like in all other variations i tried - i alway see the predefined 'gugus' from the declare section.
It seems oracle cannot read from other tables at this point. The :old.phantom_key is set (in this simple example there should come one obj_key back).
trigger:
CREATE OR REPLACE TRIGGER PSE_BKB.NUM_TR_PHANTOM_BP
BEFORE DELETE OR INSERT OR UPDATE
ON PSE_BKB.NUM_PHANTOM_BP
REFERENCING NEW AS NEW OLD AS OLD
[code]...

We have an application is must be connected to our database for specific requirements in our company but this application has a very bug thing as we must write the super DB password "Like HR password as example" clear in some files and these files must be shared so developers can use the HR password to do any action !!! I know that this application is a problem but we have to install
I can do this by creating trigger on each table will restrict DML. As example: if the operating system user is XXX, the trigger restrict the action. But not logic at all to create more than 1000 triggers on schema (This will impact badly on DB performance).
So, i need to create one trigger to fire before doing any DML on all schema tables. As example: If "MMM" the administrator operating system user trying to do insert action, he can do the action. BUT If "DEV" the developer operating system user trying to do insert action, the trigger must fire here to restrict this action.
Be noted also, i need this trigger not depend on any specific tool like Toad as any user can simply rename the exe file for toad then he can pass the trigger. At least, trigger must depend on (Operating system user & Action_type)

User1 is having 10000 tables in his schema...How can i grant "select" on a all tables of a user1 to another schema(user2) so that in future when user1 will create tables , the user2 will have "select" access on those tables automatically.
I dont want user2 to have "select any table" privillege.
User2 should not have "drop" privillege on his own tables.

I want to take backup of selected data from tables of a schema (as huge data, that is not used, causing slow query performance) I planned to create a seprate backup schema and tablespace to store the data from these tables. Then write procedures that can move the data to and fro among table of those schema. And create partitioned index on those backup tables.

I would like to be able to sort through a schema's tables to find if particular vendor numbers exist. The decode cross tab works fine, except that it needs static data for each table. How can I code a PL/SQL to populate the table_name and give a count for each row? See example below:
col table_name format a15
set numwidth 10
set lines 1000
set pages 50
select b1.table_name,
count(case when a.vendor='86444' then 1 else null end) "86444",
count(case when a.vendor='86445' then 1 else null end) "86445",
count(case when a.vendor='86469' then 1 else null end) "86469",
count(case when a.vendor='86470' then 1 else null end) "86470",

I'm trying to export a relatively large database but it's a bit more complicated than that.For one schema I need a full export / import (data included).
For another 10 schemas I need them empty, with the exception of a table in some of them which needs to be exported / imported with all data inside.Is it possible to do this with datapump utility (impdp, expdp)?
Afterwards I will be running some scripts to populate the DB instance with critical data / metadata.

I've got a schema that I've truncated all tables. I have a full schema export I took awhile back, and I'm wanting to import this into the schema to basically 'reset' it.
First time run, I got the :
ORA-39151: Table "xyz.tablename" exists. All dependent metadata and data will be skipped due to table_exists_action of skip
I've been reading through, and see suggestions to add to the par file:
CONTENT=DATA_ONLY TABLE_EXISTS_ACTION=APPEND
And I've seen others use the option for:
table_exists_action=replace
I basically want to put the data back into the tables, and have the indexes rebuilt.....

I want to create a block of code that would search in all tables in a schema for a column_name where its data_length is like 4000 let's say. This data_length is actually dedicated for a comment column. If found, all not null column with like 4000 data_length will be changed by string "Comment has been removed". I have the following script below but it seemed lacking.
begin
for rec in (select table_name, column_name from user_tab_columns where column_name like ?data_length? = 4000 order by 1,2) loop
begin
execute immediate 'update '||rec.table_name||' set '||rec.column_name||' = ''Comment has been removed'' where '||rec.column_name||' is not null';
commit;

efficient & fast method for Audit trailing tables in a Schema for any insert /update /deletes for a table. I do not want to use db triggers because of performance issues.
presently we have as system which does audit trail as below:
1. If a user changes a column value for a table ( update/insert/delete) then we call a db package and pass the parameters like table name,col name,user, operation (ins/update/delete),old value, new value,date modified,user modified etc
2. the called package will insert a record in the audit trail table with the parameters passed
3. The audit trail table is used for report generation .

how to logically connect two tables. Here is an example of what I'm trying to do:
HOSTS TABLE CPU TABLE
----------- ---------
ID HOST ID CPU
01 host1 01 proc01
02 host2 01 proc02
03 host3 02 proc01
02 proc02
02 proc03
02 proc04
03 proc01
Based on the above, I can see that 'host1' has 2 CPUs, 'host2' has 4 CPUs, and 'host3' has 1 CPU. What I'd like to do is create a query that would output:
HOST CPU
----------
host1 2
host2 4
host3 1
I'm looping through the hosts and passing the them into another query as bind variables. That's slow and cannot be the best way to do this. I'm aware that I need to using a GROUP BY HAVING COUNT, but that doesn't seem to be working. It tends to return the total count of all CPUs rather than CPUs per host.

I have taken the export backup of a table using the following command
userid=system/manager@DBATEST
file=abc.dmp
log=abc.log
Tables=X.S_ORG_EXT_X
feedback=100000
buffer=10000000
[code]......
but on querying the table it shows the number of rows as
select count(*) from X.S_ORG_EXT_X;
COUNT(*)
----------
25656051
Explain why there is a mismatch in the count of the rows in the table.

I have a UNION query having 3 parts, 1st gets date, 2nd data and 3rd displays the formatted data count :WHERE clause of 2nd and 3rd queries are same.
Problem is that I an getting different record counts when I select the overall count of records given by the whole UNION query and when I run to count the records given by each query individually.First count. Here I am selecting the overall count of records given by the query :
select count(1)
from (
SELECT SUBSTR ( '0'
|| TO_CHAR (SYSDATE, 'MM/DD/YYYY')
|| TO_CHAR (SYSDATE, 'HH:MI:SS')
|| LPAD (' ', 180)
[code]...
This count is : 1751525 Second count. Now when I run to count the records given by each query individually, here is the result
select count(1) a
from (
SELECT SUBSTR ( '0'|| TO_CHAR (SYSDATE, 'MM/DD/YYYY') || TO_CHAR (SYSDATE, 'HH:MI:SS')
|| LPAD (' ', 180)|| chr(13), 1, 200 ) dtl_record from dual
select count(1) b from (
SELECT '1'
[code]...
why there is difference of 1 (1751526 - 1751526) in the count results.

Managed to confuse myself significantly. I essentially want to write a query to determine when two counts are the same using a subquery.
Eg:
R(x,y)
Select count(x)
from R
group by x;
Then I want to run another query to determine which x's have the same count value and output these corresponding x's.

We have a partitioned transaction table in our Datawarehouse environment which has the following partition strategy
SCHEME=DATE-HASH
GRAIN=DAILY
SUBGRAIN=NONE
HASH=8
FROM=31/12/2011
We recently had to delete data from the table. This was a simple delete statement with a where clause and without taking into consideration any partition/subpartition clauses. Post committing the delete we have a count mismatch problem with two queries in particular
select count(0) count_without_parallel FROM TRANSACTION_TABLE t;
--THIS RETRIEVES *15774811* ROWS
select /* parallel(t,default) */count(0) count_with_parallel FROM TRANSACTION_TABLE t+
--THIS RETRIEVES *15777617* ROWS WHICH IS THE ACTUAL EXPECTED COUNT.
I also ran the following just to summarize
select (select count_with_parallel from (
select /* parallel(t,default) */count(0) count_with_parallel FROM TRANSACTION_TABLE t))+
-
+(select count_without_parallel from (+
select count(0) count_without_parallel FROM TRANSACTION_TABLE t)) as false_difference
from dual;
The difference in *2806* rows as expected.To re-affirm my counts I ran
select /*+ parallel(t,default) */
'count_on_t',count(*) from TRANSACTION_TABLE t
group by 'count_on_t'
order by 1;
--THIS RETRIEVES *15777617* ROWS
Removing the parallel hint reverts back to the lesser count. Not sure what is wrong but something prevents the query from parsing the whole table and/or partitions and subpartitions.

I wish to list each student's name with the number of summer courses he has completed and the number of winter courses he has completed. I am trying this :
select u.name, count(*)
from user u, course_user cu
where u.id=cu.user_id and cu.summer_course_completed = 'y'
group by u.id;
but I can get only the number of summer courses OR the number of winter courses that each student has completed, but never both simultaneously, through a single query. Is there a way to do that ?

I have got another curly one with regard to Sql Loader. My original issue via [message #513696] was resolved. In summary, SQL Loader opens a comma delimited csv file and it is able to successfully populate the appropriate Oracle table. However, during the run to process each unique csv file, SQL Loader produces a both a .log file (indicating what transpired during the load) and a .bad file of the records from the csv file that where rejected by SQL Loader.
the users have requested that "is it possible to update a separate table of the summary results of what went wrong and what was right?" It just so happens that the csv file contains some summary records (rows) with processing audit infor...as the following .bad file wrote out....
___________________________
ModuleID,ModuleSN,Lat,Lon,GMT Time,Tag Count,GMT Date,Client,Farm,Field,Variety,Machine
No Module ID ,No SN ,-30.178958,149.63844,9:55:58,0,21/04/2011,101,Widgen ,9,71BRF ,5987

,,,,,,,,,,,
Total Modules,1602,,,,,,,,,,
Mis-reads,1,,,,,,,,,,
Mis-read %,0.06,,,,,,,,,,
1. The first record (starting in the 1st postion is "ModuleID") is a heading record in the csv file and can be disregarded.
2. The secord record (starting in the 1st postion is "No Module ID") is an error record in the csv file and can be disregarded.
3. The third record (starting in the 1st postion 3500B9880611170260179BFB, ) is a valid record, however, is was rejected as it is a duplicate of a preceeding record ...and the log indicates ...
Record 124: Rejected - Error on table PTLIVE.MODULE_CSV_LOADS.
ORA-00001: unique constraint (PTLIVE.MODULE_SERIAL_NUMBER_UK) violated
4. The fourth record (starting in the 1st postion is ,,,,,,,,,,,
) is a blank record in the csv file and can be disregarded.
5. The fifth record (starting in the 1st postion is "Total Modules" has a value of 1602 which I need to capture to write into a separate table.
6. The sixth record (starting in the 1st postion is "Mis-reads" ) has a value of 1 which I need to capture to write into a separate table.
7. The last record in the csv file and can be disregarded.
The summary Oracle table is
CREATE TABLE PTLIVE.SUBMODULES_SUMMARY
( IMPORT_CSV_FILE_NAME VARCHAR2(256 ),
TOTAL_SUBMODULES_LOADED NUMBER (5),
TOTAL_SUBMODULES_MIS_READ NUMVER (5),
DATEIMPORTED DATE default SYSDATE
)
Now I would like to trap the value 1602 and load that into the Oracle column TOTAL_SUBMODULES_LOADED and the value 1 and load this into TOTAL_SUBMODULES_MIS_READ.
The name of the csv file is known and I can (as the previous [message #513696] resolved) simply use a SQL Loader control file command > IMPORT_ CSV_FILE_NAME CONSTANT "Batch_2011Jun29_TEST.csv".
