I am trying to find records in table A that don't have any corresponding records in table B
select a.ID,a.templatenames from cbe a where not exists (select 1 from cbe_child b where a.ID=b.cbe_id)
Both tables have about 100 mil rows. And there is no Parent/Child relationship here, A.ID is a PK column.how can i write this select to perform better.
I am using the SQL-Developer to access and manipulate a database. I am not very sure about the format of the database (I'm new to databases), but I had to setup the TNS-folder.
Anyway, I guess the problem is the same for any database.
I am having a table with the BOM (bill of material) positions of certain articles and I want to change the BOM quantities of some of the articles. What happens is that I can only change some of the rows. For other rows I get the message like (it is in German, so I try to translate it):
"data was commited in another/the same session already. row cannot be updated"
This error message looks like there is somebody else locked on the database and manipulating it, correct? Is that possible to see somewhere which processes/people are currently accessing to the database?
I saw that there is one process/another database, which is having the authorization to access to the database. But where can I check if this process is accessing to the database?
BTW: I used to do this process before, and it worked. I had been able to manipulate arbitrary entries on the database. I guess that the process or the person, mentioned above, hasn't been accessing to the database at that time.
I have the task that I have to determine the number of parts that need to be produced based on the number of products sold for the day (each product consists of many parts).
I am using SQL 11g Express.
The report would look something like this:
{OrderDate PartID PartDesc NumOfParts(Total for that day) 10-24-2011 2001 12" X 12" Solid Shelf 108 10-24-2011 2003 12" X 24" Solid Shelf 32 10-24-2011 3001 96" Side Panel 50
[code].......
My issue is, I can't get the equation right to produce the total number of parts. I think I need to multiply ProductPart.NumOfParts by SUM(CustOrder.Qty) Group by CustOrder.SKU.
Below I have what the calculations should look like
How to select last 10 days rows only (from sysdate)
Error
1) SQL> select * from Test where to_date(start_ts, 'DD-MON-YYYY HH24:MI:SS') > to_date(sysdate, 'DD-MON-YYYY HH24:MI:SS')-10 ; (or)
2) SQL> select * from Test where to_date(start_ts, 'MM/DD/YYYY HH24:MI:SS') > to_date(sysdate, 'MM/DD/YYYY HH24:MI:SS')-10 ; ORA-01858: a non-numeric character was found where a numeric was expected
When I use the below code in my perl script (it is oracle database):
$query = "select a.sub_id, b.name from subscribertable a, invitationBin b where a.subscriberid=b.subscriberid"; $sth = $dbh->prepare($sub_query) or die "SELECT-Query failed";
everything is ok... and when I try to add a third table...
$query = "select a.sub_id, b.name, c.phone from subscribertable a, invitationBin b, personalDet c where a.subscriberid=b.subscriberid and b.subIdx=c.subIdx"; $sth = $dbh->prepare($sub_query) or die "SELECT-Query failed";
this fails... it seems like it doesnt let me add 3 tables in the SELECT query through perl script. The strange is that when I test this query with Oracle SQL Developer, it works fine...!
i work on oracle 8i with around 950 tables in my database. when i export or import it gives me the no of rows exported / imported from each table. is it possible to take a print out of the no of rows in each table through a single query .
select count(*) from each table takes a long time , since there are 950 tables.
We have two tables, TableA and TableB that contain list of accounts and balances.The requirement is to compare the balances of accounts in both the tables, and if there is a difference, then record that difference with account number in another table.
Both TableA and TableB contain more than 10 million rows.What is the best way to do this task in PL/SQL? A join on TableA and TableB to know the differences has become very slow due to large volume.
Here the SUB1 and SUB2 are "tables" and are similar in their structure. The "Main_Table" will be update dynamically and the no of rows in this table will vary.
Now my question , i need to create a view which will have all the rows from these tables ,in the current case it is something like
create or replace view sample as select * from SUB1 union all select * from SUB2
How can this be achived. I tried as shown below:
spool file_to_exe.sql select 'select * from ' || AA ||' union all ' from Main_table; spool off
i will end up in a union all "extra" , if i do like this.
I would like to know how to increase the result set of a 'Select' statement? I did a 'Select' that should have returned 36,000 rows and got only 5000 rows. What access level do I need to change this and what do I need to change? I am trying to do a migration of data from a delimited file to a table in Oracle. Yet, the data has to be filtered out prior to loading to the table?
SQLSELECT MIN(major_zipcode) FROM TEMP WHERE MAJOR_CITIES IN (select distinct major_cities from temp);
My table has the follwoing 3 columns (in addition to others)
Col Name = active ; type=number ; values=1 (true) or 0 (false) col name start_date ; type=date; format=dd-mmm-yy col name end_date ; type=date; format=dd-mmm-yy
I need to select all rows where all active=1, start_date=<today and end_date=>today
my sql is: SELECT id, start_date, end_date FROM offers WHERE (active='1' AND start_date<='14-SEP-09' AND end_date>='14-SEP-09');
However the results are not right. Example, the first row returned is: Offer5000312 01-JAN-09 11-DEC-08
This is not correct. Due to the end_date this row should not be part of the results.
There are two tables like I posted below.I want a SQL query which selects all the rows from TABLE A which are not present in TABLE B. Also the select statement should pick all those rows which has updated value of COL_A2 in TABLE A.
TABLE A COL_A1COL_A2
AAAMOBILE BBBTABLET CCCDESKTOP DDDUNKNOWN
TABLE B COL_B1COL_B2
AAAMOBILE BBBUNKNOWN CCCDESKTOP
The select statement should return following rows from TABLE A
I have a column COL1 in table TAB1 which is varchar2. I want select only rows which has number and not alphanumeric value? I don't want to use regexp for this since
FOOTBALL PLAYERS < ID, NAME, ATTRIBUTE> 100-JIM-TALL 101-BOB-STRONG 102-MARK-SMART ...etc
I want to form a query that regardless of the total returned records, I will be able to specify how many of each "kind" of players I want returned. There are several good reasons that it has to be one query and not many.
I'm having trouble with some SQL code regarding count and an outer join.
Here is my code.
SELECT o.salespersonid, Count(*) from salesperson s, Ord o Where s.salespersonid(+) = o.salespersonid Group By o.salespersonid;
Where salesperson is a salesperson table and ord is a table containing orders.
The orders table contains a FK to salespersonid in the salesperson table.
I want it to return all salespersons along with the amount of orders they are on. It works but does not show the ones that do not appear on any orders hence the outer join.
DECLARE L_DE_TGUP_ID BBP_ALLOC.DATA_ELEMENT.DATA_ELEMENT_ID%TYPE; L_ZERO_EXP EXCEPTION; L_DATA NUMBER; BEGIN SELECT DATA_ELEMENT_ID INTO L_DE_TGUP_ID FROM BBP_ALLOC.DATA_ELEMENT WHERE DATA_ELEMENT_CD = 'TGUP'; SELECT DECODE(UPPER('0.0028'),'',0,'0',0,'NULL',0) INTO L_DATA FROM DUAL; [code]......
Here the relationship between the source and target tables is one to one. but still i am getting "unable to get the stable set of rows from the source tables" error. Source query retrieves only 2 rows which are distinct. but still getting this error.
A block shouldn't have rows from multiple tables... Is that true? I read in one of the OTN thread (i don't exactly remember the thread name) that a block can have data from multiple tables. If it doesn't have, what's the table directory in block signifies?
