Possibly the union of a left join and a right join? Smile | :)

LARGE database query

Hello,

I have two data tales in Access. One contais 2 million recors and the other contains 116000 records. The Customer name, street address, city and zip code fields need to be matched against each other across both tables in order to fin mismatches and exact matches.

Since one of the tales is very large, I am having a problem with the database program hanging every time I run the query. I tried doing this in SQL server 2005 as well, with no success.

Can anyone suggest a method for accomplishing this?

Regards.

You can create a non-clustered index for every condition and If you optimize your query that also will help you. Please post your query.

2 million records is not large in SQL server (although it may be in Access) so it has got to be your query. As suggested by others add some indexes and try optimising your query.

Open the Control Panel, go to the Administrative Tools and open the "Services" applet. From there you can start and stop the service.

Wha?

I learned here, we have to issue " netstat -an " to identify the port-1433 is configured or not..
I also checked and got the following screen,

Proto Local Address Foreign Address State
....
TCP 0.0.0.0:1433 0.0.0.0 Blush | :O

Listening
TCP MY SQL SERVER INSTALLED
MACHINE IP : 139 0.0.0.0 Blush | :O

Listening
...
and then for UDP.

And Iam not getting like the below,
TCP MY SQL SERVER INSTALLED
MACHINE IP : 1433 0.0.0.0 Blush | :O

Listening

So what I have to do? From where I have to troubleshoot? Also getting confusion, my domain only have static ip, this Sql server installed machine ip is not a static ip. Confused | :confused:

Any ideas please? Mad | :mad:

Thanks

Debugging Postgresql plpgsql [modified]

What a nightmare...
I'm currently writing pl sql for postgresql. I'm not a qualified DBA and pl sql is quite new to me. I've always rather used plain sql/linq and ADO.NET but for this specific problem it is better(I think) to write a stored procedure. The thing is that I can't seem to get debugging to work in postgresql. I'm running postgres v 8.4.(something). Is there a opensource ide that I can use to compile and debug postgresql stored procedures (Currently running dreamcoder and pgadmin III). I need help and google isn't giving me helpful answers. I have a logical error in my procedure and I can't step throught the code. I'm also using unidirect as my dataprovider in VS 2008 but guess what: No design time support for unidirect. Big up to corelab and my idiot boss for deciding on this so everything has to happen @ runtime(So much for RAD). VS 2008 would have allowed me to generate the SP if this worked...Please help me fellow programming mates. What is there to do

Help with optimization for searching a data table for a logical 'AND'

Spacix One6-Aug-09 18:03

6-Aug-09 18:03

I'm trying to search some data in a table I don't have control over and I need to figure out how to do an logical and between two specified search items.

I need to find all rows in a table that has the same value in collumn A and column B is equal to X or Y.

The is similar to the following, but it contains more than 600,000 records.

Tablename: data_table
id	record_id	parm_type	value
0	0	1001	10
1	0	1002	20
2	0	1003	30
3	0	1004	40
4	1	1001	15
5	1	1002	25
6	1	1003	35
7	1	1004	45
8	2	1005	20
9	2	1002	30
10	2	1003	40
11	2	1008	50
12	3	1007	20
13	3	1002	30
14	3	1003	40
15	3	1007	50
16	4	1001	20
17	4	1002	30
18	4	1007	40
19	4	1008	50

I want to get every value with the same record_id, that has a parm_type type of 1002 or 1003 and the value is greater than 20 for type 1002 and less than 40 for 1003.

Here is what I tried but it was taking very long and gets execution timeouts

SELECT id,record_id,parm_type,value FROM data_table
WHERE record_id IN
(
  SELECT record_id FROM data_table
  WHERE parm_type=1002 AND value > 20
)
AND record_id IN
(
  SELECT record_id FROM data_table
  WHERE parm_type=1003 AND value > 40
);

I know there have to be others ways to accomplish this, but I'm no DBA...

Couple of ideas,

1 - Create a temporary table. Execute each query separately and insert to temporary table. Finally, select the temporary table. Here is it

CREATE TABLE #temp
(
   /* your code */
);

insert into #temp
SELECT record_id FROM data_table  WHERE parm_type = 1002 AND value > 20

insert into #temp
SELECT record_id FROM data_table WHERE parm_type=1003 AND value > 40

SELECT * FROM #temp

2 - Use UNION[^]

SELECT record_id FROM data_table  WHERE parm_type = 1002 AND value &gt; 20
UNION
SELECT record_id FROM data_table WHERE parm_type=1003 AND value &gt; 40
