Hi all,
Anyone here ever used the Informix database and can give me some differences between Informix and SQL.
One of our users is thinking about purchasing a COTS product that only supports an Informix database. I need to convince the user to evaluate other rival applications that can support SQL and need some arguments in favor of not going with Informix.
Any ideas appreciated,
Faustina
Hi ,
I am an Informix user who has shifted to SQL Server,,,,I just wanted to know the equivalent of 'ISOLATION TO DIRTY READ' as in Informix in SQL SERVER....
Thanks,

Hi,
Could anyone tell me how the data can be ported from informix to sql server ?
Is there a way to run the informix query from sql server ?
Thanks,

Hi,
I am considdering to link a Informix database (running on SCO Unix) to a SQL Server 2005. Only problem is ... I have no idea how to do this! The reason I'm attempring this is to try and see if it would fix a problem I'm experiencing when using Reporting Services to generate reports from a Informix data source. I've been told that setting up a linked server might fix the problem. If anyone could perhabs guide me through setting up the linked server I would be very grateful! The ODBC credentials for setting up a connection to the Informix DB as follows:
Servername : pal_tli
Hostname : server_name
Service : pal_ser
Protocal : sesoctcp
Database : db_name
Username : user_name
Password : pword
:confused:
Hi,
I want to know how to connect to informix from SQL server and how can I run queries for the tables in Informix from sql server.
Thanks

Our entire sales database sits on an Informix server and users run their reports directly to this server.
Because of the volume of data - upwards of 7 million rows in some tables we are finding performance is becoming an issue. We realise that Informix is not the best for running queries and so are looking to replicate to a SQL server and use that as a reporting server.
My chosen method is DTS using ODBC which works fine. However due to the sheer volume of data to be downloaded each night (over a 512K wan link) we only want to download changed data.
Is there any way we can get SQL2000 to download only change data - i.e a differential download or something? We don't have a unique field in the table (for whatever reason) such as sales date or transaction ID (shops might upload old / back-dated transactions for example due to a systems failure).
If I do have to download all the data every night is my method the most efficient or is there some other approach I could use?
Ultimatly the aim here is to relieve the Informix server of the reporting overhead so any alternative ideas are welcome!
Many thanks
I need to transfer seven tables from Informix DB to SQL Server every night. Any suggestions for the best way of doing it? Is DTS the best way? How about through replication?
Thanks in advance.
Can anyone halp me with this?
I want to link/access informix database to Sql Server stored procedure.
we r doing some application and SQL server as backend DB Server. this sql server has to be updated continiously 24*7 with data from 3 external sources Cache DB, Iformix and Oracle DB servers. How to handle this in such away that all changes at 3 external sources to be updated to SQL server and this data will use by our application at frondend.
we though of ODBC., but ODBC is very very slow. It should lke Shadowing.
How to handle this?. any help will greatly appreciated.

I need help setting up replication between my SQL Server (data warehouse) database and a linked informix database.
Does anyone know the best to accomplish this. I can provide any additional information you require to help you, help me ;-)
What can be the reason(s) why I can't get data from a linked server using an ODBC datasource that works fast & fine from MS Access?
I have an ODBC connection (System DSN) configured for an Informix ODBC driver.
The Test button (belonging to this driver-setup) reports a successfull connection test.
Getting data from this database by linking tables in MS Access works fast and easy.
But I have tried for many days now to setup a linked server from SQL Server (2005)
Creation goes fine, but as soon as I issue a query, (e.g. 'select * from infrem723...remotetable' or using 'openquery')
I get the following error:
---
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "infrem723" reported an error. The provider did not give any information about the error.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "infrem723".
---
Why is Access able to read what "MSDASQL" cannot?
I am desperate - can anybody help?Thanks a lot!
Hi all,
we are about to purchase new database servers and have been offered a good deal on 64-bit Xeon machines. At present we run SQL 2000 on Windows Server 2003 both of which are 32-bit versions.
Is there any problem using our current 32-bit Server software on the 64-bit machines (apart from not being able to utilise its full power)? I'm assuming the SQL 2005 licenses are the same price regardless of 32-bit or 64-bit version. If we buy a 64-bit SQL Server version license are we going to get the best out of it on a 32-bit Windows Server edition?

I have Informix 9.4TC6 and SQL Server 2005.DB_LOCALE in Informix DB is en_US.utf8 (en_US.57372).First, I created DSN to Informix. Then tried to get data with WinSqltool and it works fine.But when I created linked server in SQL Server 2005 I have problemswith languages other than English.I get a string like:è 'å· åŒ-å|å·¥æ¥æ ªå1/4 ä1/4šç¤3/4It seems to me that SQL Server splits 2-byte characters in 2 1-bytecharacters.If in options of linked server we set Collation Name to exactlanguagewe want --then string data will be correct (of course only oflanguage that we choose).Do you have any suggestions?????????P.S. I don't want to use SSIS (DTS) for extraction from Informix DB

Hi there,
Don't know if anyone can help,
There used to be a Whitepaper on the Microsoft website comparing SQL server (2000?) against Pervasive SQL or 2000, the link was http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechnol/sql/.
But it's not working anymore.
Does anyone have a copy of this paper, or know where it's now located? I've been looking for hours and can't find it.
Thanks in advance.

hi guys,
I am joining IT industry in august,my main intrest is in database(readed some stuff of warehousing oracle 9i and sql).
However to move my career in that direction i need certification.
So here is the point,should i get MCTS(in sql server 2005) or OCP(oracle associate 10g).
My main goal is to become DBA. which of the above is more benificial.
I mean more oppurtunites.
please reply.
I have this posted in the VFP section of the forums but the more I find out about the issue the more I think there is an SQL Server security issues.
What I am doing is trying to connect to a LinkedServer of my SQL Express 2005 database running on windows vista. I have the linked server set up to connect to a local FoxPro table using the VFPOLEDB provider. If I log in as the 'sa' account I am able to do my query. But if I log into the server using a trusted connection it doesn't work. I get the error [The OLE DB provider "VFPOLEDB" for linked server "sys" reported an error. The provider did not give any information about the error.]
So I went in and set the BUILTINUser login as the sysAdmin. I also made sure that all of the security settings in SQL server were set up the same between the trusted user and the 'sa' user.
My question is, What am I missing? Is there something that I need to set on windows or is there a setting in SQL server?
Hi,
I'm using ComponentArt's Callback grids with Manual Paging.
The CA example grid uses Access:(http://www.componentart.com/webui/demos/demos_control-specific/grid/programming/manual_paging/WebForm1.aspx)
That SQL syntax produced is invalid in SQL Server 2005.
Example:
"SELECT TOP " & Grid1.PageSize & " * FROM (SELECT TOP " & ((Grid1.CurrentPageIndex + 1) * Grid1.PageSize) & " * FROM Posts ORDER BY " & sSortColumn & " " & sSortOrderRev & ", " & sKeyColumn & " " & sSortOrderRev & ") ORDER BY " & sSortColumn & " " & sSortOrder & ", " & sKeyColumn & " " & sSortOrder
So...This is what I have (simplified), and it appears return incorrect rows on the last few pages:
SELECT top 15 * FROM Posts where & sFilterString & " and Postid in (SELECT TOP " & ((Grid1.CurrentPageIndex + 1) * Grid1.PageSize) & " Postid FROM Posts where " & sFilterString & " ORDER BY " & sSortColumn & " " & sSortOrder & ") " & " ORDER BY " & sSortColumn & " " & sSortOrderRev
What other approaches has anyone used besides the "ID in (...)"?The examples I have included show the available variables: sort asc and desc, current page, number of rows on a page, etc.
I created a thread 2 days back on a performance problem RE non-trusted check constraints and foreign key constraints. We are planning to make them trusted to see if it works. On the other hand, we see about 50+ clustered/non-clustered indexes with >90% fragmentation but the page counts for all these indexes are in the range between 500-900. I'm reading in the whitepaper that index fragmentation with less than 1000 pages is not a concern.
View 7 Replies View RelatedHello All,
I would like to compare the MSCS with Polyserve's solution and thus wondering if anyone has an experience using both or knows -
What are the major differences between the two?
What are the limitations?
What are the advantages and disadvantages?
Which is advisable to use as a HA solution?
Any other information which may help me to make this decision would be appreciated.
Thanks in advance for your help!

Hi, I'm trying to set up a linked server in sql server 2000 (in both win2k an NT) with informix. I've tried using the informix cli driver to ODBC and the OLE DB driver provided by IBM, but I always get errors.
When I try to set the linked server with ODBC the error is : 7399 , It says that the provider did not give any information about the error (..??...) I tested the DSN with the dbping tool and it works fine. I also testet it linking tables with access and also works.
When I try to set up the server using OLE DB, the erro message is Error: 7303 Could not initialize data source object of OLE DB provider "ifxoledbc".OLEDB erro trace [OLE/DB Provider 'Ifxoledbc' IDBInitialize::Initialize returned 0x80040e21: [PROPID=unknown PROPERTY ID VALUE = " .... and so on.....
In both machines, sql server have sp3, the latest MDAC.
The curious thing is that in another machine running windows NT (it's almost a twin of the trouble machine) the linked server works fine and I even can run querys.
I'm desperate!! could anybody help me please!!!!!!!!!!
PD: Attached is an image that shows the error message
I am looking for a way to show how I can have a result set that shows a record with one item and the number of records where it was purchased or sold. Below is my sample data.
Use tempdb
go
create table #ItemLedgerEntry
(
ENTRYNO INT NOT NULL
, ITEMNO VARCHAR (50) NOT NULL
, POSTINGDATE DATETIME NOT NULL
, ENTRYTYPE INT NOT NULL
[code]....
I know something like this will give me results but I'd like to run one query.
select itemno, count(*) from #ItemLedgerEntry where entrytype = 0
group by itemno
order by count(*) desc
Would anyone really use ASPNET2 Membership Services with its built in Sql Server Express database for a major, heavy traffic website? How well would sql server express handle 1 million members?

I am trying to drag data from Informix to Sql Server. When I kick off the package
using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP
errors on two fields from Informix which are date data ....no timestamp part
I tried a couple of things:
Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.
Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them
as datetime but it failed.
What options do I have that will work?
I recently purchased a copy of Visual Studio 2005 Professional last month and it came with SQL Server Developer Edition. However, I noticed it also installs the express edition. If I choose not to install the Developer Edition (Im quite new to SQL) can I deploy a database I develop in the express edition on a regular SQL server?

We have reports in SharePoint integrated mode which are really slow when compared to native mode. I have been asked to research and give info on what exactly causes the delays.
Any articles which give me information as to what happens when a report is run from SharePoint server and where does it log.
I have an ODBC connection string that is working fine with the following properties:
Database="XXXXXXX",Network="YYYYYY"; strangely no server is specified in the string, but it is specified in the ODBC Connection file.
I am trying to do a new server registration in SSMS for this database.However, I don't understand where the network spec is placed.
Under Registered server name I've tried:
YYYYYYXXXXX
When I browse the server for the database instance list, I receive "network path was not found".
I even tried:"XXXXXXX",Network="YYYYYY" for the registered server name.Same error message.
What am I doing wrong ?
