Have you executed the script in Query Analyzer?
|
|
|
|
|
This is for a SQL 2005 database. I'm using SSMS.
|
|
|
|
|
If what exists, the structure does not make sense, you are selecting a row and then ask if something exists. Change the script to:
DECLARE
@Count INT
SELECT @Count = COUNT(*)
FROM sys.dm_db_index_physical_stats
(DB_ID(N'Backdrop'), OBJECT_ID(N'DBO.table'), NULL, NULL , 'DETAILED')
WHERE [avg_fragmentation_in_percent] < 30
IF @Count > 0

Could it be the concatenated name in my FROM clause?
Also note that when it wasn't in dynamic sql it worked fine. We were fighting with the WHERE clause and needed that to be dynamic. I just couldn't find a way to make the Statement (SELECT AND FROM) static and the WHERE dynamic and have it work.
Any suggestions?
Thanks

Without attempting to run it myself if I get these errors with dynamic sql I always do a quick print @sql and see what I've got. Copy it into a new query window and run it. That should give you more of an idea.

This worked and it was the concatenation of the FirstName and LastName's
Thank you again for the time.

Yup, that was on Line 4 [of the dynamic part] - exactly as the error message prompted.

Pls is it possible to generate crystal report from dataset created in code at runtime?
Thanks.
|
|
|
|
|
Short answer is Yes.
Have your application create a dataset, then assign the dataset to the CrystalReportViewer and you're done.
There are lots of examples of using Crystal Reports here in Code Project, just search them out.

pls i have done this already, i get an error: this report does not have a table.
pls help.
thanks

Could I write this as a exists statement we use this quite often and I read it has very poor performance.
WHERE `cl_client_common`.`UniqueNumber-900` IN(5337, 4439, 4725, 4096, 8078, 5912, etc, etc)
We do not know what the values will be until the user selects the clients they want.
All of the examples I see are using a subquery for the EXISTS statement and the only way I can think to write that with a subquery would be to use an IN in the subquery.
Thank you any help is appreciated.

If you are storing the list of numbers in a temp table or similar, you could use
WHERE `cl_client_common`.`UniqueNumber-900` IN (select NUMBER from TEMPTABLE)
or simply by doing an inner join to the temp table...
Otherwise, the way you are doing it will have to do!!

Learn to use the sql profiler, it will take you query and give you an execution plan, it may even suggest what fields need indexes to optomise your query, it will certinaly give you the cost of each process. You can then decide on the best approach.
As DM said you have lots of options, temp table, table variable, sub query. Use and in() or an inner join or even exists as suggested earlier. I'm not sure if the exists is a better solution, I would be tempted to go with the table variable on a large table os just a sub query as you have done. Depends on the size of the data sets and the indexing.

I generally prefer to use a join.
I caution against IN unless the values are hard-coded (which is likely a bad design in its own right).
I especially dislike subqueries in WHERE clauses.
I used to have to use them with Oracle, but I don't recall ever doing them with SQL Server.

We are joining the tables.
The values are not really hard coded...
The user is presented with a grid with checkboxes they can choose one or as many "clients" as they want in the grid.
Then we use the primary key for the record on the grid to create the new sql statement.
So user selects primary key 1,2,3,4 then our IN statement will be `UniqueNumber IN (1,2,3,4)

Greetings, all...
I'm using Visual Studio 2008 Express with C# and SQL Server 2008 backend. I'm wanting to design a lookup table form where the user can select the table from a list of items on the left (probably a TreeView with a node for each entry), then have the grid on the right reflect the contents of that table (Users, Config settings, Security, etc.). But I don't have to have a table adapter for each table that could be on the form and would like to re-use the component by setting the properties on the fly. Has anyone done this before?
As a corrolary to this, if the user double-clicks on an entry in the grid, I would like to pop-up a form to allow the user to edit that entry. Again, I would like to use a single form to do this, without having a different form and table adapter, binding source, etc., for each possible table.
Has anyone done this before and can offer any suggestions? Or would the code to do it all run-time outweigh what it would take to just have separate table adapters and forms for each possible lookup table?
Thanks in advance!

This belongs in the design and architecture forum, certainly not the database forum, this has absolutely nothing to do with database.
Having said that, this is our standard design. First you need to chuck out the tableadaptor concept, you are using the MS widget/wizard crap things. Do some research into Data Access Layer, it will change the way you manage your data.
I have a utility that takes a datatable and binds it to a datagridview, formats the DGV and the various columns based on the data types of the datatable.
I have a giant switch statement that reacts to the node click event, gets the currentview (enum of all the tables to be displayed) from the node and decides what object to get a datatable from. The datatable is then passed to the DGV loader utility.
Then on the double click event of the DGV I already know what the currentview is from the loader so I know what form to display based on the currentview. I have the ID of the record clicked on (first filed always has the ID and is not visible in the DGV) so I pass the ID to the form in the constructor and pop a dialog.
The dialog gets the record (or an empty form for add) and saves the record back to the database. It returns a dialogresult to the main form.
If the main form get an Ok result it reloads the datatable from the database and refreshes the DGV with the new record in it.
As I said bog standard do it every day UI.

Thank you for the quick reply. I apologize for the posting in the wrong location. This crossed over to several areas, so I wasn't sure where it fit best.
I'm admittedly new to working with .NET and data access, having done most of my Windows coding in Delphi recently. Time to shift some paradigms, but that's just fine with me. 
Thanks again!

Hi:
I have data that looks like this:
iYear RecordID Group
2010 1 A
2010 2 A
2010 3 A
2010 4 D
2010 5 D
2009 6 C
2009 7 C
but I need to rank or apply row numbering on the Groups sorted by the RecordID to make the data look like this:
iYear RecordID Group Group Ranking
2010 1 A 1
2010 2 A 1
2010 3 A 1
2010 4 D 2
2010 5 D 2
2009 6 C 3
2009 7 C 3
Any help would be greatly appreciated.
Thx

I would think you could use a case statement to accomplish that but that is probably not the best way.

This will make interesting reading[^] for you. Also look into PARTITION and RANK, that will allow you to rank the records over the group

When I first started working at my job we maintained local DBs for development on our own machines...so there was alot of upkeep backing up production data restore etc.
Then we had a spare server laying around so we started to use it as the devDB.
Now the server is being used for other purposes so we are back to square one which takes alot of time.
Does anyone have any suggestions of a better way to do this?
FYI we are using mySQL.

Development servers. Every time.
programmervb.netc++ wrote: backing up production data restore
Never did that; always generated test data -- it's repeatable.
|
|
|
|

I would think it would take more time to generate the amount of test data we need than it would to do backup restore...
Are there tools for this?
Also one reason the data being REAL data matters is because we are converting all apps from Access to mySQL and VB6 to VB.NET so we are running our reports against old and new data to make sure we did not screw up a conversion or the new/better ways we are writing the SQL.
