SQL & PL/SQL :: Can't Exceed 1000 Expressions In Query
Nov 18, 2011
I am trying to run the following query below in Oracle:
Select Acct_Num, Customer_Name
From Database
Where Acct_Num IN (
1,
4,
104
..,
..,
192384,
200002
)
When I attempt to run the query, I get the error message: "ORA-01795 maximum number of expressions in a list is 1000"
Is there any way I can execute this query w/o having to break the 'IN' list up by 1,000 Acct_Num over numerous amount of times? I know the 50,000+ accounts I want the info on but they are not ordered and they mix ranges with accounts I don't want. Therefore I can't use a 'BETWEEN' clause. Also, I don't have the ability to create a temp table.
I am needing to select GUIDS from a table and for this, I need the Regular Expression. My Perl is not good and not good Regular Expression. My database is Oracle 11.2.0.2.0 and the Operating System of the Machine is Linux (Oracle Version 6).
I am trying to install and create an oracle 11gR2 database on windows 7 platform. Do we need to run exceed software while we create the database? I heard that we need exceed for unix and unix based servers. But do we need it for windows OS? While installing the oracle software, the DBCA could not startup. It didnt give any error, but it couldn't startup. I am unable to download exceed software in my office machine due to security reasons. Is there any other alternative so that I could complete the oracle installation along with creating the database successfully?
I have an Oracle Database 11gR2 installed on Windows 2008 server. But there is a kind of hang sometimes arise during work hours. while i am opening control panel i saw oracle process is around 15G even we configured SGA_MAX_TARGET=6g.
just wanted to know if i create a table with 1000 columns, and use only few of them and remaining are for future use, will it affect the performance and storage?
I have an app that reads records from a driver table in order to update another (account) table. The idea is that it runs quickly but does not impact other processes on the system. In total I have around 1M records to update.
Originally I wanted to BULK COLLECT and employ a LIMIT of 1000 with a FORALL. The problem with this approach though is that I make two updates. One to the target table but I also need to update the driver table showing that I have processed the record. Therefore I cannot use this option to commit every time I reach the LIMIT by having a COMMIT inside the LOOP.
So instead I I have a FOR LOOP and test the count, if it is 1000 then I want to commit. I thought this syntax would be fine but I get the 'Fetch Out of Sequence' error. Below is a copy of the code.. Is this being caused by the double update... as the format of the code looks correct to me (though it is late!!)?
PROCEDURE update_set IS CURSOR cur_get_recs IS SELECT account_num, ttw_active_flag, acct_rowid, rowid driver_rowid FROM driver_table FOR UPDATE OF processed; [code]...
I am having one table with 4 columns where some 1500 records are there. Now I created one new column with number data type and i want value to be updated for that column starts with 1000 onwards.
Next week I will be getting an input file which will contain over 1000 data columns to be loaded into ORACLE. It's about 6,400 characters in length.
My question is...has ever created a huge ctl file like this to be used for SQLLoader, using so many columns? I will be sending certain columns(data) to certain tables, so it's not just going into 1. It will be about 6 tables.
Table contains 10k records,we are going to insert data into another table with FORALL bulk collect limit 1000. if i use 10000 ,it's completed fast compared to 1000 limit.Can u tell me which one is better Limit.
I have inherited a query that union alls 2 select statements, I added a further field to one of the select statements ( a date field). However I need to add another dummy field to the 2nd select statement so the union query marries up I have tried to do this by simply adding a
select 'date_on' to add a field called date on populated by 'date_on' (the name of the column in the first query)
however when I run the union query i get the error Ora-01790 expression must have same datatype as corresponding expression.
I have a dynamic query stored in a function that returns a customized SQL statement depending on the environment it is running in. I would like to create a Materialized View that uses this dynamic query.
I have data in a table and another in XML file,I used SQL query to retrive the data placed on the table, and link this query with XML query that retrieves the data stored in the xml file. The data stored in the table and xml file sharing a key field, but the xml contents are less than what in the table.I want to show only the data shared between the two queries, how can I do that?
e.g.:
Table emp:
e_id | e_name | e_sal 023 | John | 6000 143 | Tom | 9000 876 | Chi | 4000 987 | Alen | 7800
I have the following four tables with the following structures Table A
ColA1 ColA2 ColA3 ColA4 ColA5 AA 100 CC DD EE
Table B
ColB1 ColB2 ColB3 ColB4 ColB5 AA 100 40452 A9 CDE
when these two tables were joined like the following:
Select colA1,ColA2, ColA3, ColA4, ColB3,ColB4, ColB5 from table A Left outer join (select ColB3, ColB4, ColB5 from table B where colB3 = (select max(colB3) from table B ) on (colA1 = colB1 and ColA2 = col B2)
I have a query that is pulling back more rows when I use the dblink than when I hit the linked database directly.
For example:
select x,y,z from mytable@dblink
returns 788,324 rows
while select x,y,z from mytable
returns 712,102 rows
It's the exact same query, with the only difference being the dblink. It's not pulling the data into a cursor or array, it's a simple, straightforward query on a remote database.
Is there a technique to getting a Top-N query to work as a sub-select in a larger query -or- is there another way to generate Top-N like results that works as a sub-select?
Background:
We have a large query that is being used to build an export from a legacy HR system to a new one. Amount the data needed in the export is the employees primary phone number.
The legacy HR system allows multiple phone numbers to be stored in a simple table structure:
SELECT emp_id, phone_type, phone_number FROM employee_phones
The new HR system does allow for multiple phone numbers, however they need a primary phone number identified and stored with the employee master information. (Subsequent phone numbers get stored in alternate table.)
From a business perspective, we have decided that if they have a HOME phone in the legacy system that should be the primary in the new system, if no HOME phone, then WORK, if no WORK then CELL.
That can be represented as:
SELECT * FROM employee_people_phones WHERE emp_id = '46021' ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')
SELECT * FROM (SELECT * FROM employee_people_phones WHERE emp_id = '46021' ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results WHERE ROWNUM = 1
SELECT phone_number FROM (SELECT phone_number FROM employee_people_phones WHERE emp_id = '46021' ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results WHERE ROWNUM = 1
phone_number ------------------- 1111111111
However, when the Top-N query is added as a sub-select in a larger query using the employee id from the larger query (WHERE emp_id = export.emp_id), it fails saying that �export.emp_id� is not a valid id.
(SELECT phone_number FROM (SELECT phone_number FROM employee_people_phones WHERE emp_id = export.emp_id ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results WHERE ROWNUM = 1)
1.Any way around this? Is it possible to put a Top-N (with a WHERE clause using data from the main query) in a sub-select?
2.Any alternatives (other than Top-N) to delivering a ROWNUM=1 result with a �custom� ORDER BY statement?
Other Notes: Yes, we know we could do two queries in the data conversion first deliver the bulk data to the target table, and then update with the phone numbers. However, for multiple reasons, that is less than desirable.
I am having a Select query(below Query1) and I want to use one column(sum(col4)) from this Select query to be displayed in another Select query(Query 2). how to display this.
Query 1 :- select a.col1,a.col2,b.col3,sum(b.col4) from tab a, tab b where a.key1=b.key1 and a.key2=b.key2 group by a.col1,a.col2,b.col3
Query 2 :- select a.col1,a.col2,b.col3,sum(b.col6) from tab a, tab b where a.key1=b.key1 and a.key2=b.key2 group by a.col1,a.col2,b.col3,b.col5
I am facing problem with a select query in oracle 10g database from vb.net.It was working for oracle 9. The select statement I have written is as follows
