I have tried specifying the joins as "inner" - it made no difference.
(My understanding is that MySQL interperts a join as "inner" unless otherwise specified.)

I have also tried being specific on the join member i.e. join on hangerID.

Also made no difference.

Thanks!

Have you tried selecting from the smallest table first?

Yes - I have tried all combinations I could think of. The Explain output is identical no matter what order I use.

Frustrating!

Thanks

Hello Mr. Member 4723455,
I always think it's better to put relational condition in "ON" clause of JOIN.
You can try:

select assemdata.AssemNum,innerpack.Descrip,hanger.Descrip
from hanger
join assemdata on assemdata.hangerID = hanger.HangerID
join innerpack on assemdata.InnerPackTypeID = innerpack.InnerPackID
where assemdata.Assemnum >=60000 and assemdata.Assemnum <=60050

Bye, (sorry for my bad English) Sniff | :^)

Suppaman,

I have tried it both ways i.e. using "join on table1.id=table2.id" & using "where table1.id=table2.id".

The results from an Explain Select are identical. But I agree the on method is easier to read.

Thanks!

You can try using views:
first create a view to filter out elements of assemdata with Assemnum >=60000 and Assemnum <=60050 (50 elems) then join this view with the other two table. In this way the query plan should be different and the query execution faster (I think).
Bye ^__^

I am trying to run windows application against SQL Server 2000 and get error message dot net 2005 is developement environment

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

Both app and SQL server are local

connection string is

""Data Source={m};Initial Catalog=dbname;Integrated Security = SSPI; Trusted_Connection=Yes;"

I have tried enabling TCPIP protocoll on 2005 server but it does not help.

Please help

Thanks
Manish

The error message says it all, your connection appears to think it should be connecting to SQL Server 2005.

You always pass failure on the way to success.

SELECT COUNT(*), TelephoneNumber
From MyTable
GROUP BY TelephoneNumber

You might want to put in an ORDER BY there too. If you are only interested in the highest value then:

SELECT TOP 1 COUNT(*), TelephoneNumber
From MyTable
GROUP BY TelephoneNumber
ORDER BY COUNT(*) DESC

What do you mean? I gave you an answer to your question.

If you don't know how to use a search engine to find answers to questions, I suggest you read this article[^]. Being able to use a search engine is pretty much a prerequisite for being a developer, so I suggest you learn fast.

Without seeing your C# code, it's hard to say what the problem could actually be.

You don't have anything in your code to tell it that you are using a stored procedure. You need to set the command type to CommandType.StoredProcedure. By default, it will try to execute this as a straight forward piece of SQL.
