Products ----------------- idProduct as int, idPart1 as int, idPart2 as int, idPart3 as int
then other table, which is something like:
Parts: ---------------------- idPart as int, partName as VarChar(30)
Now, some products only take one part, but others will take as many as 3 parts. Since it's a relatively small number I thought it would be better to put 3 different idParts on the product table and have two of them allow nulls, instead of creating a Master / Detail kind of thing. My question is, how do I create a view with something like:
v_Products ----------------- idProduct as int, namePart1 as VarChar(30), namePart2 as VarChar(30), namePart3 as VarChar(30)
I'm using SQL Server 2005 (Express Edition, but the SQL is the same so...). I'm using this code:
SELECT dbo.products.idProduct, dbo.parts1.partName, dbo.parts2.partName, dbo.parts3.partName FROM dbo.products INNER JOIN dbo.parts AS parts1 ON dbo.products.idPart1=parts1.idPart INNER JOIN(...)
I've got a simple ( I think) question on views. I've got a view that has a table join in it. With this view, we want to be able to perform updates, inserts, and deletes. At this time we can do the updates and inserts, but not deletes. I've checked the permissions and the users have SELECT, INSERT, UPDATE, and DELETE. Am I missing something or are deletes just not possible in a view with a join?
CREATE VIEW update_bd_view AS select D.BD_ID, D.BD_DESC, T.BT_TYPE_TID, T.BT_TYPE_FID, T.BT_JOB_FID FROM BILLING_DESC D JOIN BILLING_TIME T ON D.BD_ID=T.BT_ID GO
I have a DB migrated from SQL Server 2000 to SQL Server 2005 and I have a strange problem that I don't find any reason.
I make a simple SQL Query with one table showing all the fields and everything goes well. But when I insert another auxiliar table and showing one field, then I can't change any field of the main table. SQL Server shows me the message Read Only Cell. Why this happens? This problem didn't happen in SQL Server 2000.
The select sentence that works:
SELECT Notas_Estructura.* FROM Notas_Estructura
The previous Select sentence modified that doesn't work:
SELECT Notas_Estructura.*, Alumnos.Apellido1, Alumnos.Apellido2, Alumnos.Nombre FROM Notas_Estructura INNER JOIN Alumnos ON Notas_Estructura.CodAlumno = Alumnos.CodAlumno
I am looking to create a constraint on a table that allows multiplenulls but all non-nulls must be unique.I found the following scripthttp://www.windowsitpro.com/Files/0.../Listing_01.txtthat works fine, but the following lineCREATE UNIQUE CLUSTERED INDEX idx1 ON v_multinulls(a)appears to use indexed views. I have run this on a version of SQLStandard edition and this line works fine. I was of the understandingthat you could only create indexed views on SQL Enterprise Edition?
Write a CREATE VIEW statement that defines a view named Invoice Basic that returns three columns: VendorName, InvoiceNumber, and InvoiceTotal. Then, write a SELECT statement that returns all of the columns in the view, sorted by VendorName, where the first letter of the vendor name is N, O, or P.
This is what I have so far,
CREATE VIEW InvoiceBasic AS SELECT VendorName, InvoiceNumber, InvoiceTotal From Vendors JOIN Invoices ON Vendors.VendorID = Invoices.VendorID
I created a query, which makes use of a temp table, and I need the results to be displayed in a View. Unfortunately, Views do not support temp tables, as far as I know, so I put my code in a stored procedure, with the hope I could call it from a View....
I compared view query plan with query plan if I run the same statementfrom view definition and get different results. View plan is moreexpensive and runs longer. View contains 4 inner joins, statisticsupdated for all tables. Any ideas?
I am receiving funny results from a query. To simplify, I have 2 tables (todayyesterday). Each tbl has the same 8 columns. My query joins the two tables then looks where either of two columns has changed. What is happening is that when checking one of the columns it seems as though sql is flipping the column, causing it to be returned in error.
result set
colA colB colC colD colE colF colG colG (from yesterday) 1 1 a b c d e m 1 1 a b c d m e
So what's happening is that the record above is actually the same record and should not be returned. There is a daily pmt column that changes but I am not using that in the query. Aside from that the two records are identicle.
I have the following situation (with a site that already works and i cannot modify the database architecture and following CrossRef tables -- you will see what i mean by CrossRef tables below)
foreach hotel, there definitely is a crossRef entry in AddressCrossRef and Address tables respectively (since every hotel has an address)
however not all hotels have thumbnail image
hence i have hotel inner join AddressXReff inner join Address ..... however i must have left outer join mediaXref left outer join media
the problem is that if there is no entry in Media or mediaXref, I don't get any results
i tried to get over it by using where (media.mediaTyple like 'thumbnail' or media.mediaType is null) but then i started getting multiple results for each hotel because media's of type movie or full_image or etc... all got returned
I had given one of our developers create view permissions, but he wants to also modify views that are not owned by him, they are owned by dbo.
I ran a profiler trace and determined that when he tries to modify a view using query designer in SQLem or right clicks in SQLem on the view and goes to properties, it is performing a ALTER VIEW. It does the same for dbo in a trace (an ALTER View). He gets a call failed and a permission error that he doesn't have create view permissions, object is owned by dbo, using both methods.
If it is doing an alter view how can I set permissions for that and why does it give a create view error when its really doing an alter view? Very confusing.
CREATE VIEW dbo.vwFeat AS SELECT dbo.Lk_Feat.Descr, dbo.Lk_Feat.Price, dbo.Lk_Feat.Code, dbo.SubFeat.SubNmbr FROM dbo.Lk_Feat INNER JOIN dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
When ever I open using SQL Entreprise manager to edit it by adding or removing a field i inserts Expr1,2.. and I don t want that. The result I get is:
SELECT dbo.Lk_Feat.Descr AS Expr1, dbo.Lk_Feat.Price AS Expr2, dbo.Lk_Feat.Code AS Expr3, dbo.SubFeat.SubNmbr AS Expr4 FROM dbo.Lk_Feat INNER JOIN dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
I don t want Entreprise manager to generate the Expr fields since I use the real fields in my application. Thanks for help
I was looking through our vendors views, searching for something Ineeded for our Datawarehouse and I came across something I do notunderstand: I found a view that lists data when I use it in t-sql,however when I try to use the statement when I modified the view (viaMS SQL Server Management Studio) I can not execute the statement. I getThe column prefix 'dbo.tbl_5001_NumericAudit' does not match with atable name or alias name used in the query.Upon closer inspection, I found two ON for the inner join, which I dontthink is correct.So, how can the view work, but not the SQL that defines the view?SQL Server 2000, up to date patches:SELECT dbo.tbl_5001_NumericAudit.aEventID,dbo.tbl_5001_NumericAudit.nParentEventID,dbo.tbl_5001_NumericAudit.nUserID,dbo.tbl_5001_NumericAudit.nColumnID,dbo.tbl_5001_NumericAudit.nKeyID,dbo.tbl_5001_NumericAudit.dChangeTime,CAST(dbo.tbl_5001_NumericAudit.vToValue ASnVarchar(512)) AS vToValue, dbo.tbl_5001_NumericAudit.nChangeMode,dbo.tbl_5001_NumericAudit.tChildEventText, CASEWHEN nConstraintType = 3 THEN 5 ELSE tblColumnMain.nDataType END ASnDataType,dbo.tbl_5001_NumericAudit.nID,CAST(dbo.tbl_5001_NumericAudit.vFromValue AS nVarchar(512)) ASvFromValueFROM dbo.tbl_5001_NumericAudit WITH (NOLOCK) LEFT OUTER JOINdbo.tblColumnMain WITH (NoLock) INNER JOIN---- Posters comment: here is the double ON--dbo.tblCustomField WITH (NoLock) ONdbo.tblColumnMain.aColumnID = dbo.tbl_5001_NumericAudit.nColumnID ONdbo.tbl_5001_NumericAudit.nColumnID =dbo.tblCustomField.nColumnID LEFT OUTER JOINdbo.tblConstraint WITH (NOLOCK) ONdbo.tblCustomField.nConstraintID = dbo.tblConstraint.aConstraintID AND(dbo.tblConstraint.nConstraintType = 4 ORdbo.tblConstraint.nConstraintType = 9 ORdbo.tblConstraint.nConstraintType = 3)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CAST(CAST(vToValue AS decimal(19, 6)) AS nVarchar(512)) ASvToValue,nChangeMode, tChildEventText, 5 AS nDataType,nID, CAST(CAST(vFromValue AS decimal(19, 6)) AS nVarchar(512)) ASvFromValueFROM dbo.tbl_5001_FloatAudit WITH (NOLOCK)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CAST(vToValue AS nVarchar(512)) AS vToValue, nChangeMode,tChildEventText, 2 AS nDataType, nID,CAST(vFromValue AS nVarchar(512)) AS vFromValueFROM dbo.tbl_5001_StringAudit WITH (NOLOCK)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CONVERT(nVarchar(512), vToValue, 121) AS vToValue,nChangeMode,tChildEventText, 3 AS nDataType, nID,CONVERT(nVarchar(512), vFromValue, 121) AS vFromValueFROM dbo.tbl_5001_DateAudit WITH (NOLOCK)
A colleague of mine has a view that returns approx 100000 rows in about 60 seconds.
He wants to use the data returned from that view in an OLE DB Source component.
When he selects the view from the drop-down list of available tables then SSIS seems to hang without any data being returned (he waited for about 15 mins).
He then changed the OLE DB Source component to use a SQL statement and the SQL statement was: SELECT * FROM <viewname>
In this instance all the data was returned in approx 60 seconds (as expected).
This makes no sense. One would think that selecting a view from the drop-down and doing a SELECT *... from that view would be exactly the same. Evidently that isn't the case.
...when I started this endeavor. I have a previously developed Lotus Notes App. The idea was simple; as I am sefl taught on Lotus Script, I figured I'd be able to stumble my way through VB.Well, it started OK. I used VB Express to get familiar with the stuff, but decided to go with a full version of VS 2005 and try and get this thing properly developed as a web app. I purchased several reference books etc., and have become relatively familiar with the forums here.First issue I have is that I simply want to use code to update or add records to an SQL DB. I know about datagridview etc., but I want to update the DB using forms, not the tabular view those controls provide. I thought it would be relatively straight forward, but found my ignorance runs deeper than I thought. When I tried to do so I am finding I am not really clear on where to make declarations etc. in the web app. If anyone could point me in the right direction that would be great. The issue with searching these forums is most posts deal with datagridview or something similar.I have spent a ton of time trying to find relevant posts or articles, but have had no luck yet.Again, all Ireally need is a nudge in the right direction. I am more than willing to plod through reference materials or articles/posts to find what I need to know, I just can't find where to even start on the info I need. Regards, Joe
Hi I have a problem with my sql WHERE query, if i manually type ([Area] = 'The First Area') then it is okay but if i try and pass the variable 'The First Area' using the
([Area] = @Area) it doesnt work.

I'm relatively new to SQL7 but I did use 6.5 a fair bit. I'm trying to test the restore of the Transaction log backup and having a bit of difficulty. The idea is that I make a complete database backup at 1am backup the transaction log every 30 minutes between 7am and 7pm. I need to be able to restore the database to a known state between 7am and 7pm with a max data loss of 30 minutes.
What I am trying to achieve is (as a test):
1)Create a small test database with a test table 2)Add some data to the test table 3)Back up the transaction log 4)Restore the transaction log to 'undo' the data added in step 2
Should be simple I think !!! The problem I am encountering is that in step 4 it won't let me restore only the transaction log (a tick automatically appears in the database backup as well). Bah !
Can someone please tell me what simple steps are required to get this to work. I need specifically on what options to chose during the backup and restore processes.
Hi, I have a table with two columns. I need to find distinct value of col1 and the correspondin repeated value of col2 for that col1 value with comma seperated list. Is there any function for this in MS SQL? I need somethgn like a 1,2,3 b 4,5 c 7 d 5,55,5

I'm trying to find out if a particular column in a table has more than 10 digits. for example: the TN column. How can I write this query? The data type for this column is bigint. Also, would it be better to change this data type to char(10) instead as it's used primarily for phone # lookups? Thanks in advance!
Hi, Im trying to create a simple search page to return a list of products from a table in a sql database. Id like to be able to search a product description column in a table I have called products using the contents of a text box. I was wondering how i can go about getting the search to check for all words the user types in rather than just a single word or an exact phrase. Im currently using the following sql query SELECT [product_title], [product_description] FROM [products] WHERE ([product_description] LIKE '%' + @product_search + '%') this works fine for single words and exact phrases but if i had product called 'fred w bloggs' and i enter 'fred bloggs' it will not return anything. Please could anyone suggest how i shoud go about this? Im not sure if my web hosting company will enable full text search or will this be required? Thanks for any help! pete_ (very new to asp.net!)
