Multiple Tables Used In Select Statement Makes My Update Statement Not Work?
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Select Statement Is Very Slow - How Can I Speed This Up?
The following stored procedure is run whenever someone searches my database. When I first created the site, this search took less than 3 seconds. Now, there is more data in the system and the search is taking over 30 seconds. I am not very good with SQL and I'm sure I am doing some dumb things. Is there a better way to write this query to speed things up?

Using A CASE Statement Within A Select Query
Hi folks, Hope you are all well. I am using a CASE statement within a SELECT query to sum up values for different customers. SELECT CR_CUST.Customer_Code, 'General_01' = CASE WHEN CR_PROD.Part_Class_Code = '01' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END, 'General_07' = CASE WHEN CR_PROD.Part_Class_Code = '07' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END, 'General_08' = CASE WHEN CR_PROD.Part_Class_Code = '08' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END FROM CR_CUST INNER JOIN CR_INVOICE ON CR_CUST.Customer_Code = CR_INVOICE.Customer_Code INNER JOIN CR_PROD ON CR_INVOICE.Product_Code = CR_PROD.Product_Code WHERE (CR_PROD.Part_Class_Code = 1 OR CR_PROD.Part_Class_Code = 7 OR CR_PROD.Part_Class_Code = 8) GROUP BY CR_CUST.Customer_Code, CR_PROD.Part_Class_Code The above query produces the following results... Customer_Code General_01 General_07 General_08 ------------- ---------------- ---------------- ---------------- 02210 10074.30 .00 .00 02347 7606.49 .00 .00 02210 .00 12618.42 .00 02347 .00 13131.63 .00 02210 .00 .00 4505.44 02347 .00 .00 5018.03 My question is this - is it possible to expand my SQL Query into a Sub Query so that each customers data appears on the same line of the results?, like so... Customer_Code General_01 General_07 General_08 ------------- ---------------- ---------------- ---------------- 02210 10074.30 12618.42 4505.44 02347 7606.49 13131.63 5018.03 I can achieve this by writing my results into a temporary table and extracting the data with the following SQL Query, but I just thought it would be really cool if I could do it in one SQL Statement without using a temporary table. SELECT Customer_Code, SUM(General_01), SUM(General_07), SUM(General_08) FROM #MyTempTable GROUP BY Customer_Code Thanks in advance, Kev

Slow Query With Java Using Prepare Statement
We are using sql server 2005 with java and the last version of driver JDBC, some querys show bad performance when you send by application but if you use sql query analyzer the performance is excellent. We have take a profiler trace and saw that Java call SP_PREPEXEC when it makes a call of preparestatement. We taken the sentence from profiler (with SP_PREPEXEC) and saw the same problem, the query plan is bad, but if we avoid use the prepare statement the query works fine and the performance problem is overcome. Since we have the application with java and use every time the preparedstatement sentence from java, it is very expensive for us , change the code. Do you have any solution for these problem?

Select Statement
Hello, I have the following query: Dim sql As Stringsql = "SELECT Events.EventID, Events.VenueID, Events.EventName, Events.EventTypeID, Events.EventOnSale, Events.VALink, "sql = sql & "Venues.VenueID, Venues.Name, "sql = sql & "EventTypes.EventTypeID, EventTypes.Name as EventTypeName, "sql = sql & "EventDateTimes.UID, EventDateTimes.EventDateTime "sql = sql & "FROM Events "sql = sql & "INNER JOIN Venues ON Events.VenueID = Venues.VenueID "sql = sql & "INNER JOIN EventTypes ON Events.EventTypeID = EventTypes.EventTypeID "sql = sql & "INNER JOIN EventDateTimes ON Events.UID = EventDateTimes.UID " eThe EventDateTimes table can contain multiple records that match with the Events table. Is it possible to adjust this query so that only one record is returned per event? Right now, if there are like 3 records in the EventDateTimes table that match the UID in the Events table, then I will see the same event name outputed 3 times. Hope it makes sense... Thanks!
