Is it not possible to put table aliases inside a string and then execute it?

I would have done them as joins rather than inner queries.

Yes, you can use table aliases inside dynamic SQL.

Table aliases are fine within dynamic SQL.
What is the error message? Try adding PRINT @Stringer after this code and before the EXEC or sp_executesql that you are using to run it.

Stupid Stupid Stupid. Turns out I had set the varchar for the string to 500 and it query had just about reached that so the string was missing the FROM section of the query.
Thanks anyway though

Is there anybody who has a merge module or any other way of deploying SQL Server 2005? The InstallShield site says they still don't have it, and that the users should make their own custom setup procedures, and Microsoft still does not show the way of easily deploy SQL server 20005 Express with any installation. But they did ban the MSDE from Vista, so any installation that includes MSDE and is targeting Vista needs to be changed.
Thanks.

Hello
I have an application writing Japanese characters to the database. When I use MS SQL 2000, it works fine - the complete string is stored, but when I use MSDE, the strings seems to be truncated 
Any ideas? Is there any setting in MSDE that I'm overlooking?
Thanks for any help

Hi Guru's,
What's the trim command on SQL?
Thanks
Dom;)
|
|

|

Hi,
Using trim in SQL 2000 - ltrim() and rtrim() as given below: removes trailing and leading blanks. Hope this helps you. 
For Example:
------------
use pubs
go
select ltrim(rtrim(fname)) from
employee
go
- Harini

I have a table that stores two types of update records. At the moment I'm using a bit field to determine the update type, e.g. IsStatusUpdate. This value is 0 for comment updates and 1 for status updates. It has been bothering me recently that this could be made a char(1) field, with the more readable 'S' for status updates and 'C' for comment updates.
My only misgiving here though is the use of a literal value that is seemingly arbitrary to the user. With 'IsStatuUpdate bit, not null', I know I must store 1 for a status update. With 'UpdateType char(1), not null', I don't know that I must store 'S' for a status update. Any thoughts on this?
|
|

|

Bit fields will required less storage.
Also better when using with code (C# for example) because you'll need to deal with true,false. not magic values (S,C).
In the GUI, you can use a check box.
I think it's always better to separate how you display data from how you store it.

If I have a DataRow and a foreign key constraint (1:N), is there a way to get a DataTable with all of the childs of the relationship?
e.g. if I have
DepartmentDataTable dep = ...
EmployeeDataTable emp = ...
ForeignKeyConstraint fk = new ForeignKeyConstraint(dep.IDColumn, emp.DepartmentIDColum);
DepartmentRow hq = dep.FindByID(666);
EmployeeDataTable allHQEmployees = magic</>(hq, fk);
?

Have you tried using the DataRow.GetChildRows() method? If you define a DataRelation instead of a ForeignKeyConstraint (which will be added along with the DataRelation) you can use DataRow.GetChildRows() to get a DataRow[] reference. Once you have DataRow[] you could instantiate a new EmployeeDataTable and copy DataRow[] into the new data table using the DataTable.ImportRow() method.
You could alternatively do something using a DataView, sort by DepartmentID and call DataView.FindRows(), then perform the same copy operation I mentioned above.
But other than creating a new table object and copying rows from one table to the next there is no way to return a new data table based on a "filter" of an existing table.

If I call GetData() on an System.Data.OleDb.OleDbAdapter, does that actually read all data from the database?
Or does it just open the rowset, and the data is read only when I access the actual rows?

System.Data.OleDb.OleDbAdapter doesn't exist, but System.Data.OleDb.OleDbDataAdapter does. But it doesn't have a GetData() method, it has a fill method which loads a disconnected dataset or datatable will all the results of the query and then disconnects (if the connection was closed before Fill() was called.

Is it possible to have a constraint that depends on a column value? For instance, I would like my DocUpdate table to require NewDocStatus is not null when IsStatusUpdate = 1, but allow NewDocStatus to be null in other records.
|
|
|
|
|
Using a check constraint you can do the following:
<br />
CREATE TABLE myChkTable (IsStatusUpdate BIT, NewDocStatus VARCHAR(25))<br />
go<br />
<br />
ALTER TABLE myChkTable ADD CONSTRAINT chkTblConstraint CHECK (<br />
(IsStatusUpdate = 1 AND NewDocStatus IS NOT NULL) OR IsStatusUpdate = 0<br />
)<br />
go<br />
<br />
--the first three will succeed<br />
INSERT INTO myChkTable VALUES (0, null)<br />
INSERT INTO myChkTable VALUES (1, 'status')<br />
INSERT INTO myChkTable VALUES (0, 'not update')<br />
<br />
--this will fail<br />
INSERT INTO myChkTable VALUES (1, null)<br />
<br />

I don't mean to sound stupid.
But what does the term "MRD" stands for in SQL Server?
Does anybody know?

Hi,
For the life of me, I haven't been able to figure the following out and I hoping someone out there can offer some good advice.
I have an ASP page that lists a lot of manuals and their associated new features for that particular release.
For example:
Manual title New Feature
manual 1 new feature1
manual 1 new feature2
manual 1 new feature3
manual 2 new feature1
manual 3 new feature1
manual 3 new feature2
Rather than have the same manual listed consecutively with a different new feature association, I would like to list the results as such:
Manual title New Feature
manual 1 new feature1
new feature2
new feature3
manual 2 new feature1
manual 3 new feature1
new feature2
Is this possible using ASP and SQL?
Here's the stored procedure:
<code>CREATE PROCEDURE [docadmin1].[sp_view_nfprodrel]
@product nvarchar (250)
AS
SELECT distinct top 100 Percent doc_id, title, relnum, substring(dn,3,14) as DN, product, New_Feature FROM nf_prodrel_man WHERE product = @product order by Title
GO</code>
Here's the view being called from the stored procedure:
<code>CREATE VIEW dbo.nf_prodrel_man
AS
SELECT TOP 100 PERCENT dbo.Books.Title + ' ' + dbo.Books.Rel_Num AS title, dbo.PROD_REL.Product, dbo.DOC_RELATIONSHIP.Doc_ID,
dbo.New_Feature.NF_ID, SUBSTRING(dbo.New_Feature.New_Feature, PATINDEX('% %', dbo.New_Feature.New_Feature),
LEN(dbo.New_Feature.New_Feature)) AS New_Feature, dbo.Books.DN, dbo.New_Feature.Description, RIGHT(dbo.PROD_REL.Product, 3)
AS RELNUM
FROM dbo.PROD_REL INNER JOIN
dbo.NF_PROD_REL ON dbo.PROD_REL.Prod_Rel_ID = dbo.NF_PROD_REL.Prod_REL_ID INNER JOIN
dbo.New_Feature ON dbo.NF_PROD_REL.NF_ID = dbo.New_Feature.NF_ID INNER JOIN
dbo.DOC_RELATIONSHIP ON dbo.NF_PROD_REL.REL_ID = dbo.DOC_RELATIONSHIP.REL_ID INNER JOIN
dbo.Books ON dbo.DOC_RELATIONSHIP.Doc_ID = dbo.Books.Doc_ID
ORDER BY dbo.Books.Title + ' ' + dbo.Books.Rel_Num, dbo.PROD_REL.Product</code>
Thanks in advance!
Regards,
Jenn

It is possible to do this in SQL, but it is much easier to acheive in the ASP page (especially as it is a presentation thing). The structure would look a bit like:
lngOldBookId = -1
For Each objRec In arrBookList
Response.Write("<tr><td>")
If lngOldBookId <> objRec.BookId Then
Response.Write(objRec.Title)
lngOldBookId = objRec.BookId
Else
Response.Write(" ")
End If
'write other bits of result table.
NextSo you only print a book title when it is different from the previous record.
Hope that helps.
Andy

Thanks Andy. I will give a try and let you know how I fare.

I normalized a table in a database project I'm working on so that instead of having something like this:
Table: entities
-----------------
ID NAME RELATED_ITEM_ID_1 RELATED_ITEM_ID_2 ..... RELATED_ITEM_ID_40
1 Entity 1 1 24 67
2 Entity 3 14 NULL 45
I now have something like these two tables:
Table: entities
-----------------
ID NAME
1 Entity 1
2 Entity 3
Table: entity_items
-----------------
ENTITY_ID RELATED_ITEM_ID
1 1
1 24
1 67
2 14
2 45
I want to return a table that has a summary of the entities table returning the top three entity_items so that it will come back looking like the original (non-normalized) entities table.
I am using a MySQL database, but any help with the basic concepts and SQL here would be appreciated. I'm sure this is a common problem people deal with, but I didn't even know the terminology to use to find an answer on the web.
Thanks.
