I get the following errors: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression. If the subquery only return one result,then it works fine,but if the subquery return more than one results, then the error occurred,how can I resolve this error?
View 3 RepliesI know this topic is all over the place, but I am not doing an INSERT, UPDATE, DELETE. My statement is a plain and simple SELECT statement and so far has worked with 116 different items in my database until I got to one.
I have a search engine and am going through every single product in our database to add information to it. This is all done through the website, but when I search for ProductID 331 and click on it, it goes to the error page that says Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
It doesn't make any sense to me that the website would error with only this one product. This is the statement I am using. Does anyone know why 1 product would be causing this error?

Here is my SQL query..
SELECT EqID, MakeID, Model, Description,
(SELECT MAX(EvDateEnd) AS MaxOfDateEnd
FROM tblEvent WHERE (EqID = tblEquip.EqID) AND (Event = 'REG')) AS RegExpire,

For example, I want to get the Max EvDateEnd from the Events table for each record in tblEquip, but not all records in tblEquip have the "REG" event, while others have multiple REG events.Some events (like EAE) I leave the tblEvent.EvDateEnd field blank to show the event is open and ongoing, such as issuing a vehicle to an employee(entity). when the vehicle is returned I enter the date in EvDateEnd essentially closing the event.

I wrote some code to update the count of a field in a table, but it is very slow. So I'm trying to do it in a subquery to speed things up, but I'm not very good with subqueries. I'm getting the error "Subquery returned more than 1 value".

I'm trying to query old Access database tables and compare them with SQL Server tables.They often don't have primary keys, or they have extra fields that had some purpose in the nineties, etc., or the new tables have new fields, etc.I need to find records - based on a set of fields specified at runtime - that are in one table but not another.So, I do this kind of query all the time in SQL, when I'm comparing data in different tables:
dim fields_i_care_about as string = "field1, field2, field3"
'This kind of thing gets set by a caller, can be any number of fields, depends on the
'table
dim s as string= ""

It tells me it can't convert a Boolean - Is there any way to do this without Linq expressions? They seem far more complex than what I'm trying to do here, and they take a lot of code, and also I can't seem to find examples of Expressions where we're comparing two fields in a subquery.Is there a simpler way? I know I could do the usual EXISTS query using JOIN or IN - in this case I don't need the query to be super fast or anything. And I don't need to use a DataTable or DataSet - I can put the data in some other kind of object.

View 3 RepliesHow to give another function's returned value in LINQ.[code]but in above query I should write code to store the return value of GetObjProperty Value(p) and add obj-p and returnValue combination to the dictionary.The last line below code is wrong. but please suggest me how to correct it. My intention is, I want output collection(say dictionary) of each fruitname and its color(returned by other function call) for all the fruits which the GetFruitColor is not nothing(it can be empty or valid string).[code]In above code last line is wrong.

I have a model that returns a dataset to a view and builds a list. The crazy thing is that I have tested this code with IE, Safari on Mac and Windows, Chrome and Opera and all return data. However, on the iPad or iPhone, zero rows are returned from the dataset object. It seems that the model is in fact passing the dataset to the view. I am using jquerymobile to render the view for the iOS devices and have taken that out of the mix to test and it still doesn't work.

As you can see an CrystalReport section is defined in the configSections.

I use in my Project the IfExistsTable function; in order to see the existence of a table.
For this purpose I use the Select statement as follows.
MASQLComm = New SqlCommand("SELECT COUNT(*) AS [RecCount] From sys.tables WHERE name Like '%" & tName & "%'", SQLConn)
RecCount = CInt(MASQLComm.ExecuteScalar)
After that I take the number which returned in RecCount. Until now the numbers was 1 and 0
And so I was turn the numbers in True or False.Now suddenly the returned number is 2 which I can't understand what it means.
I am using Enterprise block and not able to figure this out.
