I'm trying to build a simple forum. I want to display a list containing the forum names and last post date and last post author. I can view the date, but can't figure out a way to see the author. Here's the query i use:
SELECT ForumID, ForumTitle, ForumDesc, ForumTopics, ForumReplies, (SELECT MAX(AddedDate) FROM (SELECT ForumID, AddedDate, Author FROM dbo.Forums_Topic UNION ALL SELECT ForumId, AddedDate, Author FROM dbo.Forum_Reply) AS dates WHERE (ForumID = dbo.Forums.ForumID)) AS ForumLastPostDateFROM dbo.Forums
Any suggestion on how to show the author of the last message as well? Thanks in advance.
I keep receiving the following error whenever I try and call this function to update my database.
The code was working before, all I added was an extra field to update.
Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near the keyword 'WHERE'
Public Sub MasterList_Update(sender As Object, e As DataListCommandEventArgs)
Dim strProjectName, txtProjectDescription, intProjectID, strProjectState as String Dim intEstDuration, dtmCreationDate, strCreatedBy, strProjectLead, dtmEstCompletionDate as String
Dim myConnection As New SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("connectionstring")) Dim cmdSQL As New SqlCommand(strSQL, myConnection)
Forgive the noob question, but i'm still learning SQL everyday and was wondering which of the following is faster? I'm just gonna post parts of the SELECT statement that i've made changes to:
INNER JOIN Facilities f ON e.Facility = f.FacilityID AND f.Name = @FacilityName
OR
WHERE f.Name = @FacilityName
My question is whether or not the query runs faster if i put the condition within the JOIN line as opposed to putting in the WHERE line? Both ways seems to return the same results but the time difference between methods is staggering? Putting the condition within the JOIN line makes the query run about 3 times faster?
Again, forgive my lack of understanding, but could someone agree or disagree and give me the cliff-notes version of why or why not?

how can you convert it to sql syntax
I need to have a nested If statment which I can't do in sql (in sql I have to have select and from Together for example ( I can't do this in sql): select ID, FName, LName if(SUBSTRING(FirstName, 1, 4)= 'Mike') Begin Replace(FirstNam,'Mike','MikeTest') if(SUBSTRING(LastName, 1, 4)= 'Kong') Begin Replace(LastNam,'Kong,'KongTest') if(SUBSTRING(Address, 1, 4)= '1245') Begin .........

Case Statement might be the solution but i could not do it.

I'm a 3GL guy not familiar with SQL that much. What I try to add a record to shopping cart and assign a line number for each record. If the same item already exist, instead of adding a new line I'd like to add to existing line. I use to following code and I got two lines created even I was only adding the very first first. The following are the code I wrote, would anyone please give some hints. Thx.
ALTER PROCEDURE dbo.AddItemToCart ( @Cart nvarchar(50), @ItmID int, @Qty int, @ItmTyp char ) As
Declare @AllItmCount Int SELECT @AllItmCount = Count(ItmID) FROM ShoppingCart WHERE Cart = @Cart
IF @AllItmCount = 0 /*new shoppong cart*/ INSERT INTO ShoppingCart ( Cart, Qty, ItmID, ItmTyp, Line ) VALUES ( @Cart, @Qty, @ItmID, @ItmTyp, 1)
ELSE /*some item entered */
DECLARE @CountItems int
SELECT @CountItems = Count(ItmID) FROM ShoppingCart WHERE ItmID = @ItmID AND Cart = @Cart AND ItmTyp='R'
IF @CountItems > 0 /* same item entered before then add together */
UPDATE ShoppingCart SET Qty = (@Qty + ShoppingCart.Qty) WHERE ItmID = @ItmID AND Cart = @Cart AND ItmTyp='R'
ELSE /* Find the last line number */
Declare @LastLine Int SELECT @LastLine = Max(Line) FROM ShoppingCart WHERE Cart = @Cart
I am trying to create a view, but I am having trouble with the syntax (go figure!). It seems that as I reference more and more tables, my result set becomes smaller. For example, I want to return the state for all my customers then everything is fine, but when I want the state plus the site type (home, office, etc.) then I return fewer results. What is would be the correct syntax to use to return all the rows even if some of the columns have NULL?
SELECT TimeZone.LongZone, SiteMain.SiteNumber, SiteType.SiteTypeDescription FROM SiteType INNER JOIN TimeZone ON SiteType.id = TimeZone.id INNER JOIN SiteMain ON TimeZone.id = SiteMain.TimeZone AND SiteType.id = SiteMain.SiteType

Excuse my ignorance. I have been reading and studying this stuff but still some questions.
Table Datatest Table B ID Q1 Q2 Output ID Field1 Field2 1 Y N 2 Y Y 3 N N
Everytime someone adds a record to Table Datatest I want that ID automatically added to Table B. What is the best way to do that? Is this were I use a trigger and an update or is there an easier way? Also case expressions again. How do I add the results from a case to the same table using a trigger?
Like: 100 for ID 1 223 for ID 2
SELECT ID, CASE WHEN Q1 = 'Yes' THEN 100 ELSE 0 end + CASE WHEN Q2 = 'Yes' THEN 123 ELSE end as Output, FROM Datatest

Hello members, I have a trouble in retrieve correct query by SQL syntax. Ok I have use
SELECT * FROM tableOne WHERE UserID = 'mugun' AND First_Name LIKE '%tom%' OR Last_Name LIKE '%tom%' ORDER by First_Name ASC
Ok the probem is lets say, we have name TomCruise in our DB in First_NAme and Last_Name column. It return a correct value which is TomCruise. But if we change the syntax like this:
SELECT * FROM tableOne WHERE UserID = 'mugun' AND First_Name LIKE '%tomcruise%' OR Last_Name LIKE '%tomcruise%' ORDER by First_Name ASC
There is no result for the above statement. Why? Please help me . Thanx in advanced.
Here is the scenario: Table A has customer info (name and address)
Table B is a phone log table...a new row is created for each new call. In the table is a Date (when the customer was called) and a column named 'stage' that will be filled out either with the word 'follow up', 'dead', or null.
So the relationship from Table A to B is 1 to many, respectively.
I want to ask the two tables this question: Give me name and address (from Table A) and LATEST date customer was called, but ONLY if the 'stage' column says 'follow up'.
Here is the problem...Dr. Jones has three rows in Table B, his latest call was today, but stage is set to 'dead'. His second line in the table was called yesterday, with the designation of 'follow up'.
When I run my query, I pull out the row from yesterday, since it meets the criteria of 'follow up'....but this is wrong, as I only want the latest designation of 'follow up' IF its the lastest date for this customer.
Here is my syntax: SELECT DISTINCT MAX(tableB.date) AS latestdate, tableA.CONTACT, tableA.ADDRESS1, FROM tableB INNER JOINTableA ON TableB.ACCOUNTNO = TableA.ACCOUNTNO GROUP BY tableA.CONTACT, CONTACT1.ADDRESS1 HAVING (tableb.stage = 'follow-up')
Table A has three columns (aaa1, aaa2, aaa3) Table B has three columns (bbb1, bbb2, bbb3)
Common field is aaa1 = bbb1
I write a query that retrieves 3 rows out of table a (select aaa2, aaa3 from table a where (aaa2 = green) and (aaa3 = yellow)) ---------------------------------------------------------- When I now create a left outer join onto Table b, and add one more additional criteria to the where exisiting ones(aaa2=green,aaa3=yellow) which is bbb2='white', I expect to at least see my original three rows of data (since of my left outer join), but now only receive 2 rows of data, since the third row does not have bbb2 as white.
Im confused...I was expecting to see three rows of data, with the bbb2 column being null for the third row....but instead I only get two rows of data...how can I write my query that will give me what I expected ?
Can someone tell me why the first example will work, but not the second ??? ------------------------------------------------------- SELECT RIGHT(name, CHARINDEX(',', name) +1) FROM Sheet1 ------------------------------------------------------- SELECT RIGHT(name, CHARINDEX(',', name) -1) FROM Sheet1 -------------------------------------------------------
I get an error message "Invalid length parameter passed to substring function"...
If I place additional ( ) around "CHARINDEX() -1", SQL Server parses them out...
Forgive me (once again!) for not knowing this, but could someone tell me how I can BCP data from one table in a database to another table within the same database? Say my database is TEST. I want to copy the data from the table TESTING into JUSTATESTTABLE. (There are probably only 27 lines in the table)
Is it possible to have a better syntax for the following? IF(SELECT dbo.udf_Validate ((SELECT ID FROM # temp WHERE RowID=@RowID),(SELECT CodeConfirm FROM # temp WHERE RowID=@RowID),(SELECT GROUP FROM # temp WHERE RowID=@RowID),GETDATE()))=1

I'm trying to create a chart using asp. The data is stored on the sql server and it is binded to a custom made chart control.
my sql syntax fails to provide the result. well thats why i think.
To get an idea of what i would like, the X-axis of the chart should have 12 Jan and the y-axis should show a count of "2" as there are only 2 records for 12 jan on the database.
what happens now is, the chart spits out two lots of 12 Jan and draws them twice with a 1 showing on the y-axis. I want both 12 jan together on x axis with a count showing 2 on y-axis.
i hope i havent confused no one. below is the source code. any help is appreciated. TIA
