I need some advice.
I have 2 tables. They are not related in any way except that they are in the same DB. Now I need to write a select query where it returns the columns from table1 and columns from table2.
How can I achieve this?
My Query at the moment is:
SELECT Table1.Column1, Table1.Column2, Table2.Column1 AS EXPR1 FROM Table1 CROSS JOIN Table1 AS Table2
Thank you in advance!!

Since the tables are not related in any way it probably makes sense to return multiple result sets. If you are calling a stored procedure, which I highly suggest, you could just do this:
Select column1, column2 from table1
select column1 as expr1 from table2
Then you would get two results sets to work with.
Hope that helps.

Hi
Anybody know how to reset/increase the connection timeout settings for Replication
By Default it is 15, I am getting time out error "When connecting to Subscriber"
[Since our network is very poor in speed it take more than 15 to connect even with Management Studio to Login/connect to a database from client machine. In case of Login/connect we could reset time in connection properties. For Replication the connection timeout is disabled]

I think you can specify in the connection string the timeout length.

You can't do this. You have to build a string that represents your SQL statement and execute it using the EXEC statement.

SQl Server does not do a parameter substitution for Table Names in the SQL statement. To acheive this you need to build a dynamic sql and execute using sp_executesql or EXEC command.
try something like this...
DECLARE @SQLQuery AS NVARCHAR(500)
DECLARE @ParameterDefinition AS NVARCHAR(100)
DECLARE @appId AS INT
SET @appId = 10
SET @SQLQuery = 'SELECT * FROM ' + @AnswerDetailTable + ' WHERE appId = @appId'
SET @ParameterDefinition = '@appId INT'
EXECUTE sp_executesql @SQLQuery, @ParameterDefinition, @appId

I have a data source that returns rows to me. If any row is already present in the destination database (based on the primary key value)it should get updated with the content of the data source row.
Rows that are not present in the destination database should get inserted.
Can u pls tell me how to achieve this in a SSIS package.

Hello there,
I have a huge spreadsheet which I have to load into SQL server every month for reporting purposes.
The structure of this sheet is totally different from the SQL server table, otherwise I would have simply used a datareader to load the data fron the spreadsheet and 'bulk copy' it into the server.
Ther procedure I'm currently following is that I create a user table (dataset) in memory similar to the SQL table structure, and then use Table.addRow method to populate this dataset from the Excel sheet. There are around 180,000 rows in each spreadsheet, but filling the data set does not take more than 15-20 seconds max.
My real problem is when I save this table to my server, it take ages because it has to check the status of each row (new, modified, deleted,...obvoiusly they are all new in my case) before inserting it to the SQL table.
If I apply 'AcceptChanges' on the dataset, nothing gets saved, which is understandable.
Unless you have a better solution, I have two options in mind:
1) Read the user table in a datareader and use 'BulkCopy' to copy the entire data in one go, but I'm not sure if a datareader can read a dataset? If it's possible, then this will definitely solve the problem.
2) The other alternative is to save the dataset into a temp XML file and then use a DTS package to import the XML file into the server.
Your help and advice are greatly appreciated,
Hani

You can open the excel sheet as if it were a database table (either in a dataset or a datareader) using the System.Data.Oledb classes and the appropriate connection string.
This article[^] has most of the necessary details.

Thanks Rob for your advice and quick reply.
I'm sorry if I didn't explain my case well.
I'm alraedy accessing the Xls file with a datareader, using OleDB reader. The problem is after opening the Xls file and then populating it in a dataset in a different order from the spreadsheet, I then have to copy the dataset into my SQL server.
As I mentioned earlier, there are around 180,000 rows and the dataset, and this takes long time for copying into the server, since the dataadapter has to check the rows one by one to see if it is new, modifie, deleted or unchanged, and accordingle will issue the respective command: Insert, update, delete, or ignore.
What I'm looking for is a way for bulkcopying the 180,000 rows into the server in one go.
My problem would be solved if I can find a way to populate the 180,000 rows in a data container that can be later retrieved by a datareader and use the bulkcopy command of the datareader. Is that possible.
Thanks again for your support.

In my library I have a routine that takes a DataReader, cobbles up the appropriate Insert statement, and passes the Command and the DataReader to a wrapper for ExecuteNonQuery.
public virtual ulong
InsertData
(
string TableName
,
PIEBALD.Data.DataReader TheData
)
{
System.Text.StringBuilder columns = new System.Text.StringBuilder() ;
System.Text.StringBuilder values = new System.Text.StringBuilder() ;
string comma = "(" ;
for ( int runner = 0 ; runner < TheData.FieldCount ; runner++ )
{
columns.Append ( comma + this.WrapName ( TheData.GetFieldName ( runner ) ) ) ;
values.Append ( comma + "@" + TheData.GetFieldName ( runner ) ) ;
comma = "," ;
}
return ( ExecuteNonQuery
(
"INSERT INTO " + this.WrapName ( TableName ) + columns.ToString() + ") values" + values.ToString() + ")"
,
TheData
) ) ;
}

You've searched the whole Internet twice over? Blimey, that's pretty impressive...
Have a look at this article[^]. It explains how to use the ASP.NET GridView control to display repeating text and image data.

Hi.
How can I get script from my DB in SQL Server?
(a script for run it on another computer to generate my tables, views, relations, stored procedures and ...)
Best wishes

If you have Management Studio, right-click the database node in Object Explorer and select Tasks -> Generate Scripts. Follow the wizard instructions.

Hi all
I've got a problem that's driving me a bit mad, so any help gratefully received!
I've got a Data Transformation Task that is calling a parameterised stored procedure:
exec [myDB].[dbo].[vlGetOutputFile] 'Sep 28 2007', 6, 86
Within that stored procedure, I'm creating and dropping a couple of temporary tables and then returning the result set. If I click preview, I get the first 200 lines I'd expect, but as soon as I go to transformations I get the error 'Invalid object name #temp' and no columns to select from.
What am I doing wrong?
Thanks in advance
Ben

Presumably SQL Server.
The temp tables are created in the stored proc correct?
If so why are you dropping them?
|
|
|
|
|
Yes, SQL Server.
Fair point, just my natural tidiness 
Anyway, dropping the drops doesn't solve the issue....
Cheers
Ben

The reason you are getting this error is because you cannot use temp tables with DTS packages.
This is because DTS packages cannot resolve temp tables in design time.
This is a 'feature' of SQL Server 2000.
My advice is not to use temp tables with the DTS package.
What I do is pipe the result of the stored procedure to a table then call the DTS package from within a stored procedure (using the freshly populated table in the DTS package).
You can then drop the table or delete the rows once the DTS package has been run.
Alternatively if you really want to use temp tables check out this link where I explain how to get around this problem.
The solution is not pretty.
Basically my advice is to avoid temp tables with DTS packages - this is a documented 'feature'.
I hope this helps.

You always pass failure on the way to success.

Thanks for the pointer. Seems most odd that that this isn't supported - is there a reason they opted not to allow this?

Yes this is what we call a 'bug' and microsoft calls a 'feature'
What I tend to do nowadays is always pipe the results into a table then run the DTS from one table.
This has a tendency to simplify things a lot as processes, including file copying etc, are visible within the stored procedure and not hidden within the DTS package (I avoid the DTS vb scripting feature as although it looks good - try debugging a DTS package with all that code hidden away in various places).
You always pass failure on the way to success.

How can we reset the start of an identity column.
|
|
|
|
|
Use DBCC CHECKIDENT (tablename, RESEED, 9999). This would reset the next identity to 10000 on the table in question.
