No, if I host one test database each, TestDB1 and TestDB2, and a master test database, TestDBM, on the same server, DML changes we individually make will apply to TestDB1 and TestDB2, not affecting each other, and DDL changes we make to TestDBM will always be able replicate to the other two because their availability will practically always be the same as TestDBM.

The point I am trying to get across is where are you going to be making the changes initially? Surely not to a test database? You should always develop against a development installation, and then replicate your changes across to the test environment. This is where the issue lies - not in synchronising between test databases, but synchronising between development and test databases.
In general, your development environment should be kept well away from your test environment.

I want us each to have a personal dev environment, as well as a personal test environment, the latter preferably hosted together with the master test environment.
DDL changes will be made locally, in our individual dev environments, yes, but will be manually deployed to the master test, from which they should propagate back to our individual test environments.

|

So, isn't an automated approach a better choice then? Remove the danger that changes are missed between the dev and test environments.

It is and will be, but for this release an untested, automated approach seems a bit risky. I would like to move toward that though, using November to verify the the automated tasks before a December and future releases.

I wouldn't worry too much about it in a testing/development environment like what's being intended here. It's not production and whatever error that comes out of using DDL triggers are traceable and rectifiable.

I always worry whenever I hear people comment that consistency between dev and testing isn't too big a deal. The issue you have here is that you introduce something else into your testing process that doesn't need to be there. Why is this an issue?
Well, you have a development environment, which may or may not be different to a testing environment, which may or may not be different to your production environment. How do you ensure that what you did in the development phase makes it into the production phase?
Testing should replicate the production environment as much as is practicable, and should really be done up front. It shouldn't need manual intervention to ensure that "script A is run and then script B and then script C, and oh yes, we've got to run script D as well - mustn't forget that because it recreates the views that only get hit once a week, but are absolutely vital".

I agree with your point that the test env and the production env must be as similar as possible. But I can still write "intelligent" triggers that check for db existence, schema mismatches etc beforehand.
Our products go through QA in a lot of separate teams and it's impossible to replicate the production environment in all the QA setups. We neither have ownership of the test beds nor can we dictate anything. We just put in our own mechanism that gives us better insight that what the blunt test results which the QA gives us.
Triggers are not a bad thing to have. It's just plain stupid to have them in an OLTP table. But in a situation where it's fired only rarely, they can reduce a lot of code needed for a workaround.

hi All
Am migrating from SQL2000 to SQl2005. the database had been migrated. i would like to know if i migrate, the Constraint in my table like "Primarykey", does it get shipped on the migration Process or they get lost? must i start create a Primary key for each table?
Thanks

If you've used the setup migration wizard, everything usually works fine. But in case you used DTS/SSIS, the PK's may not have been replicated and you need to add constraints manually.

Very good. What have you tried so far? Plus, what database is this query in.
We don't do homework for you, and we don't do your thinking for you. We do help you if you've tried something and can't get it to work.
Hint - if you are using SQL Server, take a look at Common Table Expressions (CTEs) to accomplish this.

Trying to be a bit more helpful
But the solution has to do with CTEs, at least if your using SQL Server as this is not standard SQL:
<br />
with tmp(parent, son) as (<br />
select <br />
tab.parent, tab.son from tab<br />
where <br />
tab.parent='A'<br />
<br />
union all<br />
<br />
select <br />
tmp.super, tab.son<br />
from <br />
tmp join tab on tmp.son=tab.parent<br />
Beware of loops! In that case you need to introduce a recursion counter or a condition that restricts son<>'A'.

Hi all,
I Have the following statement...
SELECT convert(varchar,convert(varchar,datepart(yyyy,GetDate())) + case Len(datepart(MM, GetDate())) when 2 then convert(varchar,datepart(MM,GetDate()),101) when 1 then '0' + convert(varchar,datepart(MM,GetDate()),101) end + case Len(datepart(MM, GetDate())) when 2 then convert(varchar,datepart(dd, GetDate())) when 1 then '0' + convert(varchar,datepart(dd, GetDate())) end) AS [TodayDate]
Now what i planned this to do is add the leading zero in front of the day and month figure if the length is 1 to make the length 2... like this...
20071105 (notice the zero in front of the 5)
BUT it is still showing it like this...
2007115
How do i go about getting the zero in front of the 5 ??? My output needs to look like YYYYMMDD

Never Mind....
i have made this a bigger problem then it actually is... SORRY about that...
The easiest way to do this is:
CONVERT(CHAR(8), GetDate(), 112)

better you can use like...
CONVERT(CHAR(8), GetDate(), 112)
/*101-12/17/2006
102-2006.12.17
103-17/12/2006

105-17-12-2007
106-17 Dec 2006

108-00:00:00

111-2006/12/17

Hi,
Problem with converting varchar into Numeric
select DEFINITION_DETAIL_DATA.SMID, Cast(Data_Value as Numeric)as Val from DEFINITION_DETAIL_DATA
inner join DEFINITION_MST on DEFINITION_MST.SMID = DEFINITION_DETAIL_DATA.SMID Where DEFINITION_MST.MPID = 176
and Convert(Numeric,Data_Value) > 10000
Value without where condition shows like.
1 2500
2 3500
3 5000
4 10000
5 15000
6 20000
but when i add Convert(Numeric,Data_Value) > 10000 in query then its give me
an error.
Error converting data type varchar to numeric.

plz try this
select DEFINITION_DETAIL_DATA.SMID, Cast(Data_Value as Numeric)as Val from DEFINITION_DETAIL_DATA
inner join DEFINITION_MST on DEFINITION_MST.SMID = DEFINITION_DETAIL_DATA.SMID Where DEFINITION_MST.MPID = 176
and val > 10000

still no working
but i write like this
select DEFINITION_DETAIL_DATA.SMID, Convert(Decimal,Data_Value) as Val from DEFINITION_DETAIL_DATA
inner join DEFINITION_MST on DEFINITION_MST.SMID = DEFINITION_DETAIL_DATA.SMID Where DEFINITION_MST.MPID = 176 AND DEFINITION_DETAIL_DATA.SMID = 204
and Convert(Decimal,Data_Value) > 1
then it works
but i want like this
select DEFINITION_DETAIL_DATA.SMID, Convert(Decimal,Data_Value) as Val from DEFINITION_DETAIL_DATA
inner join DEFINITION_MST on DEFINITION_MST.SMID = DEFINITION_DETAIL_DATA.SMID Where DEFINITION_MST.MPID = 176
and Convert(Decimal,Data_Value) > 1

Your query is absolutely right. But “Data_Value” column contains invalid data, so this error occurs. Invalid data means column contains the following data:
-Null
-Empty
-Special Characters
-Spaces
Please check the data if contain invalid data then remove & run query, your required result obtained.
|
|
|
|

it contains following data.
SMID Data_Value
1 2500
2 3500
3 5000
4 10000
5 15000
6 20000

HI,
I am doing a project (.net) in which i have added a folder named data and added a ms access database mdb file to it ..........
So when ever i am running my project a copy of data folder is getting stored in the
debug folder and the updates and manipulations which i am doing are getting reflected in the database which is present in the debug folder
and at the time or retrieving data is coming from the data folder which i created
So please tell me a way such that the mdb file must be at a single place
