Hi all, I am currently moving from access queries to SQL and am using the query Builder In Visual web developer
to help me with the SQL Code..This has been easy while just querying the one table adapter but Now I am stuck..
I have a table adapter that links to an SQL Server database through a connection in web.config.
I have another table adapter that links to DB2 through a different Connetion in web.config.
My question is ..How do you query from one table adapter to another.
Each table adpater can only query based on the 1 connection ?
I'm trying to use a sub query in the SQL statement for a table adapter but am not getting the desired results. My Query is such: SELECT ItemTitle, ItemSize, ItemType,ItemUserOwnerID, (SELECT Displayname FROM tblUsers WHERE (tblEventItems.ItemUserOwnerID = UserID)) AS DisplayName FROM tblEventItems The Query runs fine and in the Table Adapter view of Vis. Studio the 'DisplayName' field is part of the adapter. However the problem is when I try to access it via a new instance of a table adapter it returns <DBNULL> when it shouldn't....
Im looking through this articlehttp://msdn2.microsoft.com/en-us/library/ms364060(VS.80).aspx What Im doing is this:I have a table that I need to add records to. The table has 85 or so columns and I dont want to have a stored procedure with 85 parameters! So I was thining of passing in xml to the stored procedure, when someone suggested using a table adapter. All the columns of the table (except the key field) allow nulls and the web form ive built only collects data for about 30-40 fields. I have a few questions about using a table adapter- How do I use a connection string I have in my web.config ?- How do I hook up my web form to use this table adapter ?
1) I have added new fields to the database, now seeems I need to remove method from table adapter and add it again. Is there any simple way to have table adapter refreshed after adding a field to the stored procedure? 2) Also I have noticed that when I try to edit existing method (configure option), it tells me that method name can not be the same for fill and get. any idea? It is the same now... 3) Also How do I remove the default method? Delete option is greyed out... Thanks a lot
I was trying to create a simple SP that return a single value as follows:CREATE PROCEDURE IsListingSaved@MemberID INT,@ListingID INTASIF EXISTS (SELECT [Member_ID] FROM [Member_Listing_Link] WHERE [Member_ID] = @MemberID AND [Listing_ID] = @ListingID) Return 1ELSE Return 0GOWhen I try it out in the Tableadapter's preview table, I get the correct result (1, where the entries exist). However, in the BLL, I tried to get the value as:Dim intResult as IntegerintResult = CType(Adapter.IsListingSaved(intMemberID, intListingID), Integer). However, this always returns 0 (when it should be returning 1). P.S. Curiously, breakpoints skipped the VS generated code for the adapter. What could be the problem? Thanks,Wild Thing
I have a table (tbl_a) with 2 columns: itemNames | Date . ItemNames can have duplicates. I have another table (tbl_b) with date ranges in 2 columns: startDate | endDate.
what I would like to do is: query tbl_a where date between startDate and endDate of tbl_b.
I have 2 tables Staff and Class which are as follows
Staff ID (Primary Key) FirstName MiddleName Surname Etc. . .
Class ID (Primary key) LessonTemplateID TeacherID TermID AssistantID
LessonTemplateID and TermID link to other tables which i don't need right now.
The Class.TeacherID and Class.AssistantID both link to the Staff.ID
I am trying to create a query where i can say i want to select a class.ID of lets say 12 and display both the Teachers name and the Assistants Name.
If i do just one join between Staff.ID and lets say Class.TeacherID all is fine and i can display the teacher.FirstName for a particular class.ID. However my problem is when im trying to display both teacher and assistant. Every time i try to create a query to do this the query comes back blank.
Im really stuck on this and just can't figure it out (is it even possible?).
Hello I am writing a stored procedure and instead of "hard coding" the size of the procedure parameters I would like to set them to the size of fields in my database. for example instead of declaring a parameter like this: @ProjectDescription varchar(500)
I would like to do something like this:
@ProjectDescription varchar(Select size of "ProjectDescription" From Projects);
I am working on an application with a number of tables (which I can't change) that have data of the form a1, b1, c1... a2, b2, c2...a3, b3, c3... The tables contain 5 to 10 sets of data in each row.
I want to create a stored procedure to return a cursor with a row for each set of data for a row of the table. I know I can use unions:
select a1 as a, b1 as b , c1 as c... from sometable where pk=@pk
union
select a2, b2, c2... from sometable where pk=@pk
union
select a3...
Is there a way that is more efficient (eliminates requerying the table and all the unions)?
Can any one tell me the difference between Select Query and SelectCommand in data adapters?
Using SelectCommand:
string selectSQL = "SELECT CustomerID, CompanyName FROM Customers WHERE Country = @Country AND City = @City"; SqlConnection nwindConn = new SqlConnection("Data Source=localhost;Integrated Security=SSPI;Initial Catalog=northwind");SqlDataAdapter custDA = new SqlDataAdapter(); SqlCommand selectCMD = new SqlCommand(selectSQL, nwindConn);custDA.SelectCommand = selectCMD; // Add parameters and set values.selectCMD.Parameters.Add("@Country", SqlDbType.NVarChar, 15).Value = "UK";selectCMD.Parameters.Add("@City", SqlDbType.NVarChar, 15).Value = "London"; DataSet custDS = new DataSet();custDA.Fill(custDS, "Customers"); Using Select Query:
SqlDataAdapter da = new SqlDataAdapter("select P_UID,P_EMIAL,P_NAME from p_users where p_email=@p_email and p_pwd=@p_pwd", con);
da.SelectCommand.Parameters.Add("@p_pwd", SqlDbType.VarChar, 50).Value = pwdtex.Text; Can you plz tell vat is the need for giving custDA.SelectCommand and adding parameters to that command instead of directly giving Select Query in Data Adapter? Similarly Update Command: custDA.UpdateCommand.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID") custDA.UpdateCommand.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName")Dim myParm As SqlParameter = custDA.UpdateCommand.Parameters.Add("@OldCustomerID", _ SqlDbType.NChar, 5, "CustomerID")myParm.SourceVersion = DataRowVersion.Original[C#]custDA.UpdateCommand.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID"); custDA.UpdateCommand.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName"); SqlParameter myParm = custDA.UpdateCommand.Parameters.Add("@OldCustomerID", SqlDbType.NChar, 5, "CustomerID");myParm.SourceVersion = DataRowVersion.Original; instead of above process, y cant v do above method in below procedure?
I need help with a query, and I haven't seen anything like this in a SQL book.
I will use the Northwind database for this example. The tables I am using are Products, Order_Detail, and Orders. There is a many to many relationship between Products and Orders, that is resolved by the Order_Detail table. Suppose I want to find out which products are related to each order. How would I query the tables?
Folks,While I still have some hair left, can someone help me with thisquery?I have a table "TestRunInfo". Amongst other fields there are"TestRunIndex" (Pri Key), "TesterID", "Duration", and "Status".The Status field links to a Status table, which links the index valueto a more meaningful label "Pass", "Fail" etc...As you may have guessed, there is a record for each test that anindividual tester runs, and with that record is a duration, and status(1,2,3 etc).What Im trying to do, is create a datasheet view, with a single rowfor each testerID, summarising that Testers work as follows:TesterID, Total Duration, Count of passed tests, Count of failed testsSo far I have:Select TesterID, sum(Duration), count(Status) FROM TestRunInfo GROUPBY TesterIDBut this of course purely gives the total number of tests run by thatengineer as the count. I need to break it down. Help? Someone?Please?!?!?TIASteve
I wonder how the query will be executed when querying to views.Is database engine will be extract the tables that are used to create the view and query for the result ?
I have a Fact Table with a ID column as Primary key and clustered index is created. And also I have 4 dimensions FK's of data type INTEGER. And finally, I have one aggregation measure in the Fact Table.
Now, my situation is How can I improve the speed of querying the fact table by creating any of the below indexes?
I have a table (we will cal DateTable) with several (20) columns, each being a date type. Another table's (Project) PK is referenced in the DateTable.
I am trying to write a query that will pull all dates for a specific project from the DateTable if they meet certain criteria(i.e. if the date is <= 7 days from now.
I started with a normal select statement selecting each column with a join to the project and then a where clause using
(DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()) OR (DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE())) ...
The rest of the columns(all with OR between them).
The problem with this is that because I am using OR once one of the dates meets the criteria it selects all the dates that are associated with the project. I ONLY want the dates that meet the criteria and don't care about the rest.
Obviously because I have all the columns in the select statement... So I need something like
Select ALL Columns from DateTable d Join Project p where p.ProjectID = d.ProjectID AND only dates BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()))
I'm trying to run a query on a SQL Server 2005 table which has a WHERE clause that requires a query from my SQL Compact table.
SELECT * from RemoteDB.TESTDB.dbo.Objects
WHERE Last_Updated > '2008-05-21 10:51:00'
AND Object_PARENT IN (select Object_CODE from LocalDB.PDADB.dbo.Objects)
Basicallly on a linked system, this query would find all new objects in my main database where the same objects exist in my local database. This would work just perfectly, no problems.
Now, the local database is actually on a PDA running SQL Server Compact Edition. There is currently no support for creating a linked environment. I have the option of pulling the table off the local db and pushing it to the remote db and then running the above query from within the single db and then retrieving the list of new entries and pulling them down to the local db but that is a HUGE amount of bandwidth, even if I just used the single primary key column.
Would anyone maybe have a little advice for me on how I could possibly achieve the above result on SQL Server Compact please?
I'm fairly new to SQL and am just setting up a Windows 8 app using an Azure SQL server. The issue I have is looking up a part number supersession and getting the latest number. One part number can have multiple supersessions (ie RTC5756 > STC8572 > STC3765 > STC9150 > STC9191 > SFP500160 ).The data I am supplied monthly has both the superseeded items and the supersession information in both columns and is not easy to decipher - for example:
The newest part number is kept in a separate table - called "source" - which in this instance is SFP500160. I need access to the latest part number but also to the part's previous numbers, due to the fact that some people may still be stocking them as an old part number and for them to search by. Is there an easy and efficient way of doing both a lookup for the supersessions and a join on the two tables to minimize the queries on the database?
I am setting up extended events more or less just fine, however I am a bit confused as to how to read and load them into a table for querying. In particular the offset part - is there a way to load just a given dates worth in?
I've got the files configured to be 20MB before rolling over, the XE is running all the time.
So if i load in the full file now, say that covers 2.5 days worth, when I load it again tomorrow to get the updated data I'm also reloading today, which is a waste?
I presume I am going about this wrong, but lack an example that really goes into detail of practicalities of loading this data.
Can anyone tell me how to access data from Stored Procedures using data adapters? My task is to select a row which is valid with data particular value.

How can i bind data to dropdownbox of one field in the table using datasets and data adapters? How can i insert data in database using data adapters?Can any one solve this?
I'm a newbie to SQL and wanted to see if someone could help me write a query. I store historical options data in a SQL data base and I'm trying to create a query that will retrieve all ATM (at the money options).
For each unique stock symbol (STOCK_SYMBOL) in my database find the strike price (STRIKE) which is closest to the stock price (UND_LAST). This will be refined by the EXPIRATION and OPT_TYPE
The following query returns all options not just ATM options.
SELECT STOCK_SYMBOL, UND_LAST, STRIKE, EXPIRATION FROM DATA
WHERE EXPIRATION > '2007-02-01 00:00:00' AND EXPIRATION < '2007-02-28 00:00:00' AND OPT_TYPE = 'CALL'
I am using MS SQL Server 2005 Import and Export Wizard (.net framework Data Provider for mySAP Business Suite. )
as a interface between SAP and MS SQL 2005.
Once the connection is created i can use basic query to fetch the data from SAP tables ie., SELECT * FROM AFPO
But say I want to EXTRACT data just for month of July from AFPO.
AFPO does not have date field so you have to join AFPO to AUFK and AUFK to COEP to fetch the date as a criteria to restrict data for the month of July .
This can be done in ABAP by view or Interim Table, if you have Developer Key.
Can anyone please tell me if aforesaid is possible with MS SQL Server 2005 Import and Export Wizard query ?
Hello, I want to find all the entries where the date field is a specific date; so I may have 5 entries with the date 1/1/2006, and I want to find all of those. However, datetime fields in SQL Server also have the time, so how do you handle that? Can you just say where requestdate = getdate() to get all of the entries that have records for today? How does time affect this?

Hey, What is the best way to query two datetime values to see if they are alike? I need to determine if an [AccountEndDate] is today (both values are datetime). Using "Like" does not work. Thanks!
If you create a view such as CREATE VIEW TestView AS Select * FROM customers_table WHERE CustomerID between 213 AND 3443 Each time you want to select from the view - is the View going to perform the WHERE clause on the customers_table, or not? Or does the view already have the virtual rows?, meaning it does not have to perform a where clause (WHERE CustomerID between 213 AND 3443) on the customers_table, and just performs an inner join with the rows it already has?
I have a usage table Aaccessdate (datetime)useridpageidI need to write a sql that would do a report on a monthly basis. ( how many pagehits per month)All is fine - and my SQL looks likes thisselect count(pageid)from A.The twist here is , I do not want to count those records if the same user visits the page on the same day.For Eg02/03/2005 10:09:09.000 user1 page102/03/2005 15:09:09.000 user1 page102/03/2005 11:09:09.000 user2 page202/03/2005 16:09:09.000 user3 page3I want my count to give me back 3 instead of 4.Can this be done?ThanksRajini
I have a table containing prices. This table will be queried very often to provide quotes for clients.So to ease the burden on the server I want to cache the table and then just query the cached version.However it seems that I can only cache the table as a datatable. This means I have to query the datatable to get the prices for each quote.I'm not sure how to query a datatable. Is ther syntax similar to querying a SQL table?In fact is this best way to go about things?Any help would be appreciated.G
