Aggregate Operation Cannot Take A Nvarchar Data Type

Oct 5, 2002

I recently upsized my acess 2000 db to SQL 2000, but I am now having errors . . .

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E07)
[Microsoft][ODBC SQL Server Driver][SQL Server]The sum or average aggregate operation cannot take a nvarchar data type as an argument.
/data_count.asp, line 4


The code within the asp file:
<% dataSQL = "SELECT SUM(filesize) FROM DL where show=1"
Set datacount = my_Conn.Execute(dataSQL)
anBytes = datacount(0)
%>

Can someone point me to a solution?

Error Converting Data Type Nvarchar To Int

Feb 28, 2008

Hi,


I get "Error converting data type nvarchar to int." It is some kind of SQL exception. This is the code in my application.

SqlConnection sqlConnection1 = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

SqlCommand cmd = new SqlCommand();



Object start;



string activityID = Session["activitygroupID"].ToString();

cmd.Parameters.AddWithValue("@ActivityGroupID", activityID);

cmd.CommandText = "get_startdate";

cmd.CommandType = CommandType.StoredProcedure;

cmd.Connection = sqlConnection1;

sqlConnection1.Open();



SqlDataReader reader = cmd.ExecuteReader(); //The code stops here!!!

start = reader["StartDate"];

sqlConnection1.Close();


The stored procedure on the SQL-server looks like so. StartDate is of DateTime type.


ALTER PROCEDURE [dbo].[get_startdate]

-- Add the parameters for the stored procedure here

@ActivityGroupID int

AS

BEGIN

SELECT StartDate

FROM dbo.CurrentGroup

WHERE ActivityGroupID = @ActivityGroupID

END


I appreciate any help!

Error Converting Data Type Nvarchar To Numeric

Dec 12, 2014

I am using MS SQL Server 2008R2 along with VB 2010.The first question is: why is it even trying to convert anything to numeric? I have NO numeric data types. And I don't have any nvarchar data types either. I'm very confused.Doesn't nchar include any and all characters, in any combination? Should I change everything to text data type? Maybe something else? Some values are going to be blank. The Lab/Source Lots have numbers, letters and dashes.

My stored procedure:

ALTER PROCEDURE dbo.MChemsInsert
(
@LabLot nchar(10),
@Chem nchar(50),
@Source nchar(50),
@SourceLot nchar(10),

[code]....

Transact SQL :: Converting Data Type Nvarchar To Bigint

Apr 17, 2015

This is a common error for SQL Server, but I got it in a uncommon way.I have a table called - tblIDNumber where there are two columns - IDN_Number [NVarchar(200)] and Temp [BigInt]

If I run,
SELECT  *
FROM    dbo.tblIDNumber
WHERE   IDN_IDNumberTypeStaticValue = 33
        AND IDN_Removed = 0
        AND CAST(IDN_Number AS BIGINT) = 1

SQL Server give me the error:
Msg 8114, Level 16, State 5, Line 1
Error converting data type nvarchar to bigint.

I first thought IDN_Number in type 33 has characters, but it doesn't, becasue the below query works!!!

UPDATE dbo.tblIDNumber
SET Temp = CAST(IDN_Number AS BIGINT)
WHERE  IDN_IDNumberTypeStaticValue = 33
        AND IDN_Removed = 0

To workaround, I ran the query,

UPDATE dbo.tblIDNumber
SET IDN_Number = '123'
WHERE  IDN_IDNumberTypeStaticValue = 33
        AND IDN_Removed = 0

and then I ran the first query, and SQL Server does NOT give me the same error - Msg 8114, Level 16, State 5, Line 1 Error converting data type nvarchar to bigint.

Second query approved there is nothing wrong from converting the value in IDN_Number to a BigInt, but the third query gave the hint that data might be the cause?????

finally, I found the root cause to be an index that the first query uses :

CREATE NONCLUSTERED INDEX [IX_tblIDNumber_Covering] ON [dbo].[tblIDNumber]
(
[IDN_Removed] ASC,
[IDNumberCode] ASC
)
INCLUDE ( [IDN_Number],
[IDN_Reference]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 85) ON [PRIMARY]
GO

If I remove the index, the first query works without the error.

Error Converting Data Type Nvarchar To Datetime

Jun 2, 2008

Hi,

I'm pretty desperat after trying solving the above problem in several days. I hope somone here can help me :-)

I have this stored procedure. When I try to Execute the storedprocedure where I have a date as parameter I get the above error.

I checked (many times), that the input parameter is a datetime format (30-05-2008) and also I checked the tabel and it is datetime format. I checked the table to see if it was english datetime format - but all the datetimes that are listet are listed in danish datetime format DD-MM-YYYY.

In the stored procedure I try this:


fProjectSkuTimeStamp >= @ReducedTime

I can't figure out where it gets that nvarchar from?

My stored procedure look like this:


set ANSI_NULLS ON

set QUOTED_IDENTIFIER ON

set NOCOUNT ON

go

ALTER PROCEDURE [dbo].[GetProjectSkuList]

@fProjectFId AS INTEGER = null, --ProjektId

@ReducedTime AS DATETIME --Tidsrum fra



AS

BEGIN

SELECT tProjectSku.fProjectSkuPId, tProjectSku.fCompanyFId, tProjectSku.fProjectFId,

tProjectSku.fProjectSkuDate,

tProjectSku.fOurContactFId, tProjectSku.fOurContactF2Id, tProjectSku.fOrderFId,

tProjectSku.fProjectSkuTimeStamp,

tProjectSku.fProjectSkuNote1, tProjectSku.fProjectSkuNote2, tProjectSku.fContactFId,

tProjectSku.fStoreTransactionsFId,

tProjectSku.fProjectSkuSalesPrice, tCompany.fCompanyName, tProject.fProjectName,

tOurContact.fOurContactFirstName + ' ' + tOurContact.fOurContactLastName AS CreatedBy,

tOurContact_1.fOurContactFirstName + ' ' + tOurContact_1.fOurContactLastName AS Responsible,

tContact.fContactFirstName + ' ' + tContact.fContactLastName AS ContactFullName,

tStoreTransactions.fStoreTransactionsCostPrice,

tStoreTransactions.fStoreTransactionsSerialNo





FROM tOurContact AS tOurContact_1 RIGHT OUTER JOIN

tContact RIGHT OUTER JOIN

tProjectSku LEFT OUTER JOIN

tStoreTransactions ON tProjectSku.fStoreTransactionsFId = tStoreTransactions.fStoreTransactionsPId ON

tContact.fContactPId = tProjectSku.fContactFId LEFT OUTER JOIN

tOrder ON tProjectSku.fOrderFId = tOrder.fOrderPId ON tOurContact_1.fOurContactPId = tProjectSku.fOurContactF2Id LEFT OUTER JOIN

tOurContact ON tProjectSku.fOurContactFId = tOurContact.fOurContactPId LEFT OUTER JOIN

tProject ON tProjectSku.fProjectFId = tProject.fProjectPId LEFT OUTER JOIN

tCompany ON tProjectSku.fCompanyFId = tCompany.fCompanyPId



WHERE

(tProjectSku.fProjectFId = @fProjectFId) AND

--fProjectSkuTimeStamp >= CONVERT(datetime, @ReducedTime, 120)

fProjectSkuTimeStamp >= @ReducedTime

ORDER BY tProjectSku.fProjectSkuPId DESC

END

Problem With Converting The Nvarchar Value 'xxxxxID' To A Column Of Data Type Int.

Jan 23, 2007

Hi,
I have a webform with a drop-down listbox, binded to a table and a GridView, binded to another table. My goal is when I select a value (country in my case) in the drop-down listbox to change what is shown in the GridView, based on the ID that I get from the drop-down listbox.
Here is the code (the important parts...):
Select a Country : <asp:DropDownList ID="CountriesDropDownList" runat="server" DataSourceID="SqlDataSource2" DataTextField="Name" DataValueField="CountryID" Width="220px" AutoPostBack="True">
</asp:DropDownList>
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>"
SelectCommand="SELECT [CountryID], [Name] FROM [DS_Country]">
</asp:SqlDataSource>
<asp:GridView ID="ProvincesGridView" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="ProvinceID,CountryID,Name,ShortName,Description" DataSourceID="SqlDataSource1" BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" HorizontalAlign="Left" >
<Columns>
..............................
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DineSelectConnectionString %>"
DeleteCommand="DELETE FROM DS_Province WHERE ProvinceID=@ProvinceID"
SelectCommand="SELECT ProvinceID,CountryID,Name,ShortName,Description FROM DS_Province WHERE CountryID=@ddlCountryID"
UpdateCommand="UPDATE DS_Province SET CountryID=@CountryID,Name=@Name,ShortName=@ShortName,Description=@Description WHERE ProvinceID=@ddlCountryID"
InsertCommand="INSERT INTO DS_Province (CountryID,Name,ShortName,Description) VALUES (@CountryID,@Name,@ShortName,@Description)">
<SelectParameters>
<asp:ControlParameter Name="ddlCountryID" ControlID="CountriesDropDownList" PropertyName="DataValueField" />
</SelectParameters>
</asp:SqlDataSource>
 
When I run it I get this error "Syntax error converting the nvarchar value 'CountryID' to a column of data type int.". If I specify the Type="Int" in <asp:ControlParameter>..</> I get "Input string was not in a correct format. "
This is supposed to be easy, but I can't make it work ! Any suggestions will be more than welcome.
Thanks.

Transact SQL :: Error Converting Data Type Nvarchar To Float

Sep 24, 2015

In the following code I want to compare 2 values: AccessVal and SQLVal. The values are stored as nvarchars, so I'm isolating the numeric values in a subquery. Notice I'm only selecting 1 row. The commented line, where I compare the values, is throwing the error.

SELECT QA_AutoID, AccessVal, SQLVal
,ROUND(ABS(CONVERT(float, AccessVal,1)),0) as AccessFloat
,ROUND(ABS(CONVERT(float, SQLVal,1)),0) as SQLFloat
FROM QA
WHERE QA_AutoID in (
SELECT TOP 1 QA_AutoID
FROM QA
WHERE ISNUMERIC(SQLVal) = 1 AND ISNUMERIC(AccessVal) = 1
)
--AND ROUND(ABS(CONVERT(float, AccessVal,1)),0) <> ROUND(ABS(CONVERT(float, SQLVal,1)),0)
ORDER BY ROUND(ABS(CONVERT(float, AccessVal,1)),0) DESC
,ROUND(ABS(CONVERT(float, SQLVal,1)),0) DESC

Here is the output with the comparison commented out...

Here's what I get with the comparison line activated:

I've tried converting to numeric, int and bigint instead of float. I've tried CAST instead of CONVERT. Nothing works.

Getting Server Error Syntax Error Converting The Nvarchar Value 'Sonoma' To A Column Of Data Type Int.

Apr 20, 2007

Hi, all
I'm getting this error at runtime when my page tries to populate a datagrid. Here's the relevant code.
First, the user selects his choice from a dropdownlist, populated with a sqldatasource control on the aspx side:<asp:SqlDataSource ID="sqlDataSourceCompany" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT [PayrollCompanyID], [DisplayName] FROM [rsrc_PayrollCompany] ORDER BY [DisplayName]">
</asp:SqlDataSource>
 And the dropdown list's code:<asp:DropDownList ID="ddlPayrollCompany" runat="server" AutoPostBack="True" DataSourceID="sqlDataSourcePayrollCompany"
DataTextField="DisplayName" DataValueField="PayrollCompanyID">
</asp:DropDownList>
Then, I use the selectedindexchanged event to bind the data to the datagrid. Here's that code:
 1 Sub BindData()
2
3 Dim ds As New DataSet
4 Dim sda As SqlClient.SqlDataAdapter
5 Dim strSQL As String
6 Dim strCon As String
7
8 strSQL = "SELECT [SocialSecurityNumber], [Prefix], [FirstName], [LastName], [HireDate], [PayrollCostPercent], " & _
9 "[Phone], [BadgeNumber], [IsSupervisor], [SupervisorID], [IsUser], [IsScout] FROM [rsrc_Personnel] " & _
10 "WHERE ([PayrollCompanyID] = @PayrollCompanyID)"
11
12 strCon = "Data Source=DATASOURCE;Initial Catalog=DATABASE;User ID=USERID;Password=PASSWORD"
13
14 sda = New SqlClient.SqlDataAdapter(strSQL, strCon)
15
16 sda.SelectCommand.Parameters.Add(New SqlClient.SqlParameter("@PayrollCompanyID", Me.ddlPayrollCompany.SelectedItem.ToString()))
17
18 sda.Fill(ds, "rsrc_Personnel")
19
20 dgPersonnel.DataSource = ds.Tables("rsrc_Personnel")
21 dgPersonnel.DataBind()
22
23 End Sub
24

 
I'm assuming my problem lies in line 16 of the above code. I've tried SelectedItemIndex, SelectedItemValue too and get errors for those, as well.
What am I missing?
Thanks for anyone's help!

I am reading multiple databases into a single dataset, putting each read into a new datatable in the set. Ultimately, I want to merge the multiple tables (they are all from different DB tables in different locations using the same schema). I am also combining this with data from an Oracle database which is in yet another table in the same dataset.

Here is my question:

I will not be propagating any changes to this data back to its original source, but I will be populating it out to Active Directory. (Don't worry; I'm not asking any AD questions here.) But I do want to run SELECT, DELETE, and UPDATE queries against the data in the dataset in memory without writing it out to a separate file. Based on that type of usage, would I be better to use a DataReader or a DataAdapter to do the read from the original database? If I use a DataReader, can I still update the data in memory? In either case, what's the correct methodology to update data in a dataset in memory?

Thanks!

Reporting Services :: Aggregate Function On Large Value Type

Apr 20, 2015

We are constrained to use a model that stores records in a main table and various attributes of the record in a second table. Something like this: main record table CAR, attribute table CAR_DETAILS with CAR_DETAILS have key value pairs like "color" "blue" and "doors" "4".

For reports we need to flatten the one to many nature of this to get CAR and color and doors by using an aggregate function like: 

car_id, max(car_detail.value) filtered on car_detail.key = "color", max(car_detail.value) filtered on car_detail.key = "doors". 

This works on other tables but the car_detail table (shall we say) appears to store its values as blobs. In any case when we attempt to aggregate we get "The query uses an aggregate function on a large value type expression. Large value type expressions can not be aggregated."

Since we can't change the model, we would need to use another function to change this to a smaller string (or date, these are actually mostly date), but none of the very limited set of functions available seems to work to make this aggregation possible (and there is no "first" or anything else similar). 

The list of functions available in Report Model Queries can be found at [URL] .....

Operand Type Clash: Nvarchar Is Incompatible With Image

Oct 4, 2006

I uploading an image from a web page into Sql Server 2000 database. I call a stored procedure with the parameter @Flag of type Image. When I tried to pass a null value to this parameter I got the error:"Operand type clash: nvarchar is incompatible with image".I was adding the parameter like this:sqlCmd.Parameters.AddWithValue("@Flag", DBNull.Value);After trying few different things I found a workaround using the following:sqlCmd.Parameters.Add("@Flag", SqlDbType.Image);sqlCmd.Parameters["@Flag"].Value = DBNull.Value;Possibly a bug in the SqlCommand.Parameters.AddWithValue method ?
