Hi
Im using VS 2005 and C# and the Enterprise Library 2.0. I want to design an application that can't be affected by the Database engine i used (SQL Server, Orcale, My Sql, Postegree) how can i acheive that since MySql and Postegree is not supported in Ado.net as
provider.
Thanks for your help

I already install the MySql Connector Net 1.0.7 but the problem is that i can't configure the MySql database through the Enterprise Library configuration, since My Sql is not listed as factory provider, i also can't use something like that:
Database db=DatabaseFactory.CreateDatabase();
the above line can work with Sql server and Orcale but how to work with MySql.
My purpose is to unify the code regardless of the database engine.

Ah, so you're using the Microsoft Data Access Application Block? You're quite right, it only supports SQL Server, Oracle and DB2 out of the box. You need to modify the code if you want to support MySQL and Postgres as well. The source code for Enterprise Library is supplied in the installation package, so you can inspect that.
There's a connector here[^] which may help, but note that it already says it's outdated and the original author hasn't fixed it. Still, it may give you a start.
Stability. What an interesting concept. -- Chris Maunder

probably you should use IN operator
SELECT f1 FROM table2 WHERE table2.f2=4 AND table2.f3 in (121034,1,41)

insert into table1 (f1,f2,f3)
select f1 from table2 where table2.f2=4 and table2.f3=121034,1,41
hi,
Are u supplying 3 values to query?? then u might be thinking like
(select f1 from table2 where table2.f2=4 and table2.f3=121034),1,41
if this is rite then u confirm - Is that query returning only one value??
After u shud write something like this :
select f1,1,41 from table2 where table2.f2=4 and table2.f3=121034

Your post could use a better subject line. A better subject line would briefly describe the problem. For example: "Syntax error in SELECT statement"

Hi All!
I had two table in SQL Server: tblNew_Details and tblNews. They were connected over pass by two fields: New_DetailsID in tblNew_Details with New_DetailsID in tblNews.

I only display a field that have the same New_DetailsID(in tblNews). But I have a problem which display two fields with the same New_DetailsID.
Please help!

Hi,
Can someone please tell me why the following SELECT statement is bring back no results:
SELECT
WineryID_PK,
WineryName,
WineryEstablishedYear,
WineryOwner,
WineryDescription,
CountryID_PK,
CountryName,
RegionID_PK,
RegionName,
WineryDateInserted,
WineryDateUpdated,
(MemberFName + ' ' + MemberLName) AS WineryUpdatedBy,
WineryStatus,
WineryHasImage
FROM
Winery
LEFT OUTER JOIN Members
ON Winery.WineryUpdatedByID_FK = Members.MemberID_PK
INNER JOIN Region
ON Winery.RegionID_FK = Region.RegionID_PK
INNER JOIN Country
ON Region.CountryID_FK = Country.CountryID_PK
WHERE
Members.MemberUsername = 'Serasmus'
AND WineryID_PK = 20;
If I remove the Members.MemberUsername = 'Serasmus' then it bring back just the winery details, otherwise nothing. Username Serasmus does exist in the members table.
Regards,
Brendan

U are doing a left join with the winery table on the left side..
so the query will return 'Serasmus' only if this member's id is present in
the WineryUpdatedByID_FK column of winery table..is it?
so ur statement of "Username Serasmus does exist in the members table" is not really helpful
try executing this query part by part ... u may get a solution faster..

Thanks, but I was not thinking clearly.
I changed it to the following and it works fine:
SELECT
WineryID_PK,
WineryName,
WineryEstablishedYear,
WineryOwner,
WineryDescription,
CountryID_PK,
CountryName,
RegionID_PK,
RegionName,
WineryDateInserted,
WineryDateUpdated,
(m2.MemberFName + ' ' + m2.MemberLName) AS WineryUpdatedBy,
WineryStatus,
WineryHasImage
FROM
MemberInWinery
INNER JOIN Winery
ON MemberInWinery.WineryID_FK = Winery.WineryID_PK
INNER JOIN Members AS "m1"
ON MemberInWinery.MemberID_FK = m1.MemberID_PK
LEFT OUTER JOIN Members AS "m2"
ON Winery.WineryUpdatedByID_FK = m2.MemberID_PK
INNER JOIN Region
ON Winery.RegionID_FK = Region.RegionID_PK
INNER JOIN Country
ON Region.CountryID_FK = Country.CountryID_PK
WHERE
MemberInWinery.WineryID_FK = 20
AND MemberInWinery.MemberID_FK = 12;
Thanks for your help!!

hi all,
I am copying a table to another table using
select * into targettable from sourcetable .
The new table named "targettable" is created but the primary key (constraints) and default values for the table are not coming as "sourcetable".
Is there any way to have a table copy with the same table structure and design??????.

Currently there is no such method to copy the constraints from the source to target table during table creation. For applying the constraints you must Alter the table.
