[MS Sql] Data Type Nvarchar

Jul 9, 2006

Hi everybody,

I'm using SQL Server Management Studio Express.
I'm trying to create a field which contains a text entered by the user. So, it should be able to contain at least 500 characters.

I used the type "nvarchar(MAX)". The problem is that the type contains about 50 characters max!!
I couldn't find out where and how to fix that.
If you have any idea :)

Thanks a lot

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

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!

Pass NVARCHAR (or Other String-type) Var As A Column Or Table Name In SQL

Jun 21, 2004

Hey folks, the question is fairly simple, unfortunately the answer has proven rather elusive.

Is it possible to declare a variable which would then be used to identify either a column or table in an SQL statement?

Here's a basic idea of what I'd like to do:

DECLARE @myVar AS NVARCHAR(50)

SELECT *
FROM @myVar

or

DECLARE @myVar AS NVARCHAR(50)

SELECT @myVar
FROM MyTable



I'm probably looking for some sort of built in function that will accept an argument here... like COLUMN(@myVar) or something of the like. I just don't know where to look...

To do this Ichange the data type in SQL Server, then I change the parameter code inthe calling procedure, as per below:cmd.Parameters.Append(cmd.CreateParameter("@title", adVarWChar,adParamInput, 255, title));becomes:cmd.Parameters.Append(cmd.CreateParameter("@title", adLongVarWChar,adParamInput, 1073741823, title));However, when I do this, for some reason, the field is still limited to255 characters - when I try to update the field with 256 characters,the error 'Application uses a value of the wrong type for the currentoperation.' occurs.Why is this? I've checked that the correct data is contained in theparameter. When I look at the data in the database, the column inquestion shows the content, whereas the next column, which has alwaysbeen of type text, shows '<LongText>' - does this mean anything? Do Ineed to do something special to convert the column from nvarchar totext?Many thanks,Iain

Index Creation Causes Error The Conversion Of A Char Data Type To A Datetime Data Type Resulted...

Jul 23, 2005

Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error. Dropping the index solves theproblem.Can anyone tell me why an index would cause a query to fail?Thanks a lot in advance,AmirCREATE TABLE [PTRANS] ([CHL#] [varchar] (100) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[CHCENT] [numeric](2, 0) NOT NULL ,[CHYYMM] [numeric](4, 0) NOT NULL ,[CHDAY] [numeric](2, 0) NOT NULL ,[CHTC] [char] (2) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]GOCREATE VIEW dbo.vwTransactionsASSELECT CONVERT(datetime, dbo.udf_AddDashes(REPLICATE('0', 2 -LEN(CHCENT)) + CONVERT(varchar, CHCENT) + REPLICATE('0', 4 -LEN(CHYYMM))+ CONVERT(varchar, CHYYMM) + REPLICATE('0', 2 -LEN(CHDAY)) + CONVERT(varchar, CHDAY)), 20) AS TransactionDate,CHL# AS AssetNumber,CHTC AS TransactionCodeFROM dbo.PTRANSWHERE (CHCENT <> 0) AND (CHTC <> 'RA')*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
