MS Access can support even 2 million of records.
But considering other factors like
Feature SQL Server 2000 Access 2000
database size 1,048,516 TB 2 GB plus
linked tables size
objects in a database 2,147,483,647 32,768
user name length 128 20
password length 128 14
table name length 128 64
column name length 128 64
index name length 128 64
Number of concurrent users limited 255
columns per table 1024 255
table size limited 1 GB
number of indexes in a table 250 32
number of columns in an index 16 10
bytes per row 8060 2000
number of tables in a query 256 32
columns per SELECT statement 4096 255
nested subqueries 32 50
number of enforced relationships 253 32
(obtained from http://www.allinterview.com/showanswers/63402.html[^])
it is better to go with SQL SERVER.
However, cost is also a factor!
But if your requirement is not so high, you can go with SQL SERVER EXPRESS EDITION. which is free
But the license is limited.(hope 10 users)
Hope this answers your question.

Can v create permanent hidden tables in sql 2000 and how?
|
|
|
|
|
Hi,
Though the question is not very clear to me but if you mean that you want to give preference of View access over table access to the users,then the answer is
DENY SELECT ON TABLE TO USER
GRANT SELECT ON VIEW TO USER
If you want to hide the system tables in SQL SERVER 2000, follow this steps:
1) Choose a registered server
2) Right click on that and select Edit SQL Server Registration properties
3)Uncheck
Show system databases and system objects
Hope this helps

Hi everybody!
I have my own kind of server that for each client keeps an oledb connection opened. It also uses a thread pool for serving the clients. Now let's say the connection between my server and SQL server breaks for whatever reason. While it's down if my server attempts to do anything with the database it obviously fails. Then network issue gets solved.
If my server attempts to continue manipulate the same oledb connection - it still fails. If I reconnect it fails anyway as long as there are those other olddb connections for those other clients of mine. Only when all oledb connections are closed I can start connecting successfully to the SQL server. It seems that in multithreaded/same exe session environment all oledb connections must be closed and reopened in order to recover. Is that true? Or is there a better way to force oledb to revive connections?
Please help!
Thanks a lot in advance.

Hi guys,
I am having a weird issue, I am trying the following and for some reason varchar(50) value is set to null when I encrypt or decrypt it. If I change it from varchar to nvarchar it works. Our table in the database is already set to varchar to store the encrypted information and can't change it due to licensing issues. Please help, what am I doing wrong?
OPEN SYMMETRIC KEY DSBEncryptionKey DECRYPTION BY CERTIFICATE EncryptDsb
DECLARE @encryptedNum varchar(50) -- varchar doesn't work here, nvarchar works
SELECT @encryptedNum=EncryptByKey(Key_GUID('DSBEncryptionKey '), '111000614');
select CONVERT(varchar(50),decryptbykeyautocert(cert_id('EncryptDsb'), NULL, @encryptedNum))
FYI, my symetric key uses AES_256 algorithm.
Please help!

I have a query that is joining tables and calculating the SUM.
It seems to be working, however; the "SUM" is double what it should be.
Any ideas:
Select, spendaccount, spend.fromcode, spend.keyword,
spend.kwtype, SUM (Rev.trans)
Trans, SUM (rev.newaccounts)
newaccounts, SUM (rev.gross) Gross, SUM (rev.refunds)
Refunds, SUM (rev.net) Net, spend.clicks, spend.spend
From spend, Rev wherespend.fromcode=
rev.fromcode
group by spend.fromcode
Regards,
Hulicat

Hi,
Which SUM you are talking about?
SUM (Rev.trans)?
SUM (rev.newaccounts)?
SUM (rev.gross)?
SUM (rev.refunds)?
SUM (rev.net) Net?

Hello and thanks for the reply; I am not sure on the approach but here is what I am trying to do:
Spend table-> spend (SUM'd), clicks, kytype account
Rev table-> transactions, newaccounts, gross, refunds, net (SUM'd),
From spend, Rev wherespend.fromcode=
rev.fromcode
----all in one output--------

I am assuming certain things.
I have created both the tables and has inserted certain values. Please look into it whether you also have the same values or not!
tblSpend
COLUMN NAME DATATYPE
----------- -------
SPENDACCOUNT int

SPEND int
Values in tblSpend are
101 1 KeyWord1 1 1 10
102 2 KeyWord2 1 10 11
103 3 KeyWord3 2 21 15
104 4 KeyWord4 3 22 16

110 10 KeyWord10 1 2 3
tblRev
COLUMN NAME DATATYPE
----------- -------
NEWACCOUNTS int
GROSS int
REFUNDS int
NET int
TRANS int
FROMCODE int
Values in tblRev are
1 10 20 10 10 1
2 20 30 10 20 2
3 30 40 15 25 3
4 40 50 45 5 4

7 70 100 100 0 7
8 70 100 50 50 7
6 111 300 120 180 6
The Query is
SELECT
S.SPENDACCOUNT, S.KEYWORD,
S.KWTYPE,S.CLICKS,S.SPEND,
D.FROMCODE,D.TRANS,D.NEWACCOUNTS,
D.GROSS,D.REFUNDS,D.NET
FROM (
SELECT
T.FROMCODE,
SUM (R.TRANS) TRANS,
SUM (R.NEWACCOUNTS) NEWACCOUNTS,
SUM (R.GROSS) GROSS,
SUM (R.REFUNDS) REFUNDS,
SUM (R.NET) NET
FROM TBLSPEND T, TBLREV R
WHERE
T.FROMCODE= R.FROMCODE
GROUP BY T.FROMCODE
) D, TBLSPEND S
WHERE S.FROMCODE = D.FROMCODE
OUTPUT:
101 KeyWord1 1 1 10 1 1 10 20 10 10

Hello Niladri_Biswas, thanks for your help.
Actually I know what the problem is I am just can't figure out the query.
Example of data a problem.
Fromcode Spend.spend rev.gross
ABC 10 70
ABC 20 50
ABC 10 20
Results look like the following:
rev.gross sum'd + spend.spend
Fromcode spend.spend rev.gross
abc 140 (expected 90)
abc 160 (expected 100)
abc etc
I want the total for each column based on the fromcode but not joined sums if that makes sense.
Thanks and Regards

Hulicat

If you want to solve a problem like this; sometimes you can figure out what is going on by running a similar query to the one you do have but instead of using SUM use COUNT. This is just a debugging method, not the solution.
I suspect if you did that with your original query all of the lines that you saw double would come out with a count of 2 or higher.
Maybe you should try something more like this for your query:
select
spend.account,
spend.fromcode,
spend.keyword,
spend.kwtype,
(select sum(rev.trans) from rev where rev.fromcode=spend.fromcode) trans,
(select sum(rev.newaccounts) from rev where rev.fromcode=spend.fromcode) newaccounts,
(select sum(rev.gross) from rev where rev.fromcode=spend.fromcode) gross,
(select sum(rev.refunds) from rev where rev.fromcode=spend.fromcode) refunds,
(select sum(rev.net) from rev where rev.fromcode=spend.fromcode) net,
spend.clicks,
spend.spend
from spend
order by spend.fromcode
I don't have mysql running so I can't test it myself.

I am still trying to get it to work, this one didnot return any results
SELECT S.SPENDACCOUNT, S.KEYWORD, S.KWTYPE,S.CLICKS,S.SPEND, D.FROMCODE,D.TRANS,D.NEWACCOUNTS, D.GROSS,D.REFUNDS,D.NET FROM ( SELECT T.FROMCODE, SUM (R.TRANS) TRANS, SUM (R.NEWACCOUNTS) NEWACCOUNTS, SUM (R.GROSS) GROSS, SUM (R.REFUNDS) REFUNDS, SUM (R.NET) NET FROM TBLSPEND T, TBLREV R WHERE T.FROMCODE= R.FROMCODE GROUP BY T.FROMCODE ) D, TBLSPEND WHERE S.FROMCODE = D.FROMCODE
This one "hung" the database:
Thanks...for the help I think I am close
select spend.account,spend.fromcode,spend.keyword,spend.kwtype, (select sum(rev.trans) from rev where rev.fromcode=spend.fromcode) trans, (select sum(rev.newaccounts) from rev where rev.fromcode=spend.fromcode) newaccounts, (select sum(rev.gross) from rev where rev.fromcode=spend.fromcode) gross,(select sum(rev.refunds) from rev where rev.fromcode=spend.fromcode) refunds,(select sum(rev.net) from rev where rev.fromcode=spend.fromcode) net, spend.clicks, spend.spendfrom spend order by spend.fromcode

Hello,
I have to Update a Csv file into Sql Server DataBase, the file contains 200 000 records.
So how can i do to optimize the DbTransactions ?! because 200 000 is too big and i want not overload the Database Server.
Solution1: create a global DbTransaction with IsolationLevel=RaadUncommited
Solution2: create a DbTransaction foreach Record with IsolationLevel=RaadUncommited
Solution3: create a DbTransaction for a group of Records with IsolationLevel=RaadUncommited
Already Thanks.

What do you mean by "update" csv into database? You update records in place, or insert new ones?
Look at BULK INSERT at MSDN. It is very fast, you can insert all in temp table and then update records, if that is your goal.
|
|
|
|
|
thank you for you answer.
I update a record.
I know the BULK INSERT but the CSV file have to be in the same machine of Sql Server Data base!

i am using ms sql server 2005. i used full text search (fts) facility. now i want to know that does fts cares about sequence of a phrase. for example
("select * from news AS N INNER JOIN containstable(news,datacontent,'local' AND 'company') AS A ON N.[id]=A.[KEY] ORDER BY A.RANK DESC",connec)
this returns results that includes local and company but anywhere in the document. but i want it like "my local company is very big." so i mean the word "company" must come after "local" (at least 1 time) to have a result. how can i do this. i tried it as 'local company' but an error occured...
