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.

Deja View - the feeling that you've seen this post before.

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'.

Inserting Leading Zero for datepart(MM and datepart(dd

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)

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.

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

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.

Use SQL Server Service Area Configuration Manager to allow remote connections. Also allow both TCP/IP and Named Pipes protocols. That should solve your problem.

Open management studio, right click on the server and properties. Then under security you can change it to mixed mode.

In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties.

On the Security page, under Server authentication, select the new server authentication mode, and then click OK.

In the SQL Server Management Studio dialog box, click OK, to acknowledge the need to restart SQL Server.

Make sure you restart the server. and remember "If Windows Authentication mode is selected during installation, the sa login is disabled. If you later change authentication mode to SQL Server and Windows Authentication mode, the sa login remains disabled. To enable the sa login, use the ALTER LOGIN statement."

Why have you posted this question? The link I sent you in response to your previous question also explained how to get a list of fields for an Access table.

You should learn to search Google for answers to your questions before posting. Otherwise it looks like you can't be bothered to search for a solution to your problem yourself.
