I've created a script that adds user data to a database, however, I'd like to check the email entered is unique within the database.
I've already started the query at comm2 but not sure how to progress the script so it tells the user if the email address is already taken.

My ASP.NET MVC web app has a weird issue. In VS debugging mode it works as expected, but when I publish it to dedicated web server (windows 2003, IIS6) a sql query returns previous data even though underlying data was already updated through the same connection. It looks like as if a query returns cached data. What might be the problem?
View 2 RepliesI am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.
I have a SQL Data Source that displays records after going through the Query Builder and select "Test Query" yet when I save it, go back to the design mode and select View in Browser I get nothing but a blank screen.
View 3 Repliesi have been having trouble trying to find out what is wrong with my sql select query... i wanted to select a sessionID by comparing the tourID and dates. the dates datatype at the database is datetime and the value of itemSessionDate is in string. i tried to convert itemSessionDate to date and dateAndTime but it gave me mm/dd/yyyy while the date in my database is dd/mm/yyyy hh:mm:ss. so i thought i can try using the itemSessionDate string as it has the same value as the one return from the database. but it keeps on goin to the if not reader.hasRows and quit the statement

I have been utilising a SELECT query such as the following:
SELECT SRFILE.SR_GROUP, SRFILE.SROWNERSHIP, SRFILE.SRCONMAE, BSFLBWF_1.Incidentx,
BSFLBWF_1.Severityx, BSFLBWF_1.Openx, BSFLBWF_1.Closex, BSFLBWF_1.Closurex, BSFLBWF_1.Customerx, BSFLBWF_1.Availabilityx, BSFLBWF_1.KPIx,
CONVERT(Decimal, BSFLBWF_1.Minsx) AS Expr1, BSFLBWF_1.Unusedx, BSFLBWF_1.FirstIntx, BSFLBWF_1.RepeatIntx, BSFLBWF_1.Corex,
BSFLBWF_1.OffPeakx, BSFLBWF_1.NonCorex, BSFLBWF_1.DedTypex, CONVERT(money, BSFLBWF_1.SchoolChargex) AS Expr2, CONVERT(money,
BSFLBWF_1.LANMLEChargex) AS Expr3, BSFLBWF_1.KPIFailx, BSFLBWF_1.Overridex, BSFLBWF_1.Reasonx, BSFLBWF_1.Contactx,
SRFILE.SR_CLOCK, SRFILE.SR_BACK_REASON, CONVERT(int, BSFLBWF_1.Minsx) / CONVERT(decimal, BSFLBWF_1.FirstIntx)
* 100 AS PERCENTAGE
FROM support.SRFILE INNER JOIN
BSFLBWF AS BSFLBWF_1 ON BSFLBWF_1.Incidentx = SRFILE.SRONUMBER
WHERE (BSFLBWF_1.Closex IS NULL) AND (BSFLBWF_1.DedTypex = 'School' OR
BSFLBWF_1.DedTypex = 'LAN-MLE')
UNION ALL
The rest of the query continues as the above albeit selecting the same data from different tables and works fine.
The issue I have is that I want to Select some more data (another SELECT query) but with a different Where clause e.g. WHERE (BSFLBWF_1.KPIx NOT LIKE 'KPI%' OR
BSFLBWF_1.KPIx NOT LIKE 'Proactive%') AND (BSFLBWF_1.Availabilityx LIKE '')
The problem is that this WHERE clause returns data which the above in bold has null values for (and thus doesnt work). Im still selecting the same data its just the WHERE Clause has changed. Is it possible to run such a query? If so, can it be done via a sub query?
I have an SQL 2005 db with a table named "industry_suppliers."
I've created a query to enable someone to search this table using 3 parameters.
The results need to be grouped by "product_description" (which is essentially a category). When displayed on an .aspx page, for example, the results need to look like this:
Apples
Acme Apple Company
Bradbury Orchards
Oranges
A1 Citrus Company
Belfast Growers, Inc
Bradbury Orchards
Notice how "Bradbury Orchards" is repeated under both categories. This is the result I want, EXCEPT in cases where someone wants to filter the search results by category. Let's say someone wants to search just for apple suppliers. The problem I'm having is that any record that appears under apples will also get listed again under any other categories associated with that record. So, searching for apple suppliers, the results are this:
Apples
Acme Apple Company
Bradbury Orchards
Oranges
Bradbury Orchards
I'm having trouble figuring out how to revise my query to avoid this problem.

I have partitioned a table and it has been partitioned according to an account id. ie also rows that have accountid =1 will be in A partition and all rows that have accountid = 2 will be in B partition. so now if i execute a query with where condition accountid =1 sql server will search only in A partition. Suppose if i add another condition to it ie where accountid=1 and place="aaa" will this query search only A partition or the entire table?
View 3 RepliesI have stored procedure which selects records from an SQL table based on a bunch of user-input parameters.Just discovered that if a record in the table has null values in some of the columns (I haven't figured out which ones yet), then the SELECT is not returning the record (even if it satisfies all the parameters).The SELECT statement is supposed to allow for nulls, and I've been over it a bunch of times and am not sure what I'm doing wrong.Or do I need to get rid of all the null values in the SQL table, and prevent new ones from being introduced?

I have an asp.net site which includes a "search" page that queries an SQL table, then redirects the user to a "results" page where the results of the query are displayed. The parameters for the query are assembled into a string which is the SELECT statement. I've been asked to add additional functionality that requires a secondary search which takes place on the "results" page. How can I pass the parameters from the "search" page to the "results" page so that I can access those parameters in the code behind? Here's the first page code behind (I inherited most of this from another developer):
[Code]....
And the second page--it would be on line 51 that I would need to insert the parameters from the search above:
