Integration Services :: Error Converting Nvarchar (512) To Varbinary (max)
Aug 27, 2015
I am using rowVersion to detect rows that need to be re-extracted for my ETL. The first step in the ETL is to get MIN_ACTIVE_ROWVERSION() from the database, as well as the rowVersion from the last successful ETL run. Both of these values are saved in variables in SSIS. Since SSIS doesn't have an associated data type, these values are converted to nvarchar(512) before getting sent to SSIS.
I'm now trying to create a stored procedure to grab the data out of the source system. The sproc takes RowVersionMin and RowVersionMax as input parameters. Those parameters are then converted to varbinary(max), and I use them in a query to select the appropriate rows.
When I run the sproc in SSMS, it runs without a problem. However, when I try to use the sproc as a data source in SSIS, I get the following error: "Error converting data type nvarchar to varbinary". Why SSIS has a problem with this, but SSMS does not? The sproc code looks like this:
ALTER PROCEDURE [dbo].[dw_DimComment_DataLoad]
@RunType varchar(3),
@RowVersionMin nvarchar(512),
@RowVersionMax nvarchar(512)

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!

Hi,
I used to work with Sql 2000 and I could easily import a text file into my database and then convert the fields (all nvarchar) to appropriate data types. However, this procedure does not work with Sql 2005.
After I import a text file to Sql 2005 and when I convert nvarchar to numeric, I get "Error converting data type nvarchar to numeric".
Could you please let me know how can I fix this issue. Thanks in advance for your reply.

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!

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),

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,

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.

It would be nice if SQL Server Everywhere could support NVARCHAR(MAX) and VARBINARY(MAX), even if they would just be alias' for NTEXT and IMAGE. This would somewhat simplify the interoperability with SQL Server 2005 (i.e. no need to have different scripts for each database type).

Hi,
I can't seem to fix the following error in my stored procedure.
Error Message: Conversion failed when converting the nvarchar value '1007-001' to data type int.
The line of code in my stored procedure that seems to be the problem is the following:
CASE WHEN [Order Details].[Job No] IS NULL THEN [Orders].[Order No] ELSE [Order Details].[Job No] END
Order No has a data type of INT and Job No has a data type NVARCHAR(8). In the above case statement i'm not trying to convert anything but just display a column depending on the out come of the case statement. If anyone knows how to get around this error you help would be very welcome.

I'm currently loading a package that does a lookup on a column of data type nvarchar(4).The values itself are (A+, A, B+, B, C, D, /). The strange lookup behaviour is happening for each of the cases, so it's not related to a specific value. After trying to put the cache on NO CACHE, the lookup works perfectly. When using the default FULL CACHE the strange behaviour happens. Could it be related to the data type? I have not yet tried to use a CHAR instead of a NVARCHAR but it looks like people have similar issues using CHAR.

On the ntext, text, and image (Transact-SQL) page at
http://msdn2.microsoft.com/en-us/library/ms187993.aspx
it states
"Important:
ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead. For more information, see Using Large-Value Data Types."
Considering this warning, is VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) support going to be implemented in SQL Server Compact Edition?

I have a csv file and I would like to load this file by SSIS in SQL Server.
One column of this file contains xml infos (it is about 60000 charachter), and I would like to have an xml column in Table in SQL Server.
From here the only ssis types, which able to contain so much character are DT_NTEXT and DT_TEXT.
If I want to have xml type in the target table in sql server, these both DT_NTEXT and DT_TEXT should be converted to DT_WSTR.
The Problem is: DT_WSTR can only contains 4000 charcters. In my situation with this infos, I can't have an xml column in target table in sql server.

I'm editing an SSIS package. The source column has datatype float and the data is stored like 1,2 instead of 1.2. To change this into a period instead of comma there is a derived column step in the ssis package. The expression in this derived column step to change this goes as:<o:p></o:p> (DT_STR ,32,1 252)(REPLACE((DT_STR,32,1252)SUBSCHAAL_SCORE,",","."))<o:p></o:p>
where SUBSCHAAL_SCORE is the name of the column. As you see the data is converted into a string. I need it to be converted into a numeric datatype (18,6) instead of string/varchar but it must also handle the first issue with changing the comma into a period. <o:p></o:p>

I have a SSIS package which is reading from an Excel file.
The Excel is created from a report from another system and sometimes the date of birth formats as a Date and sometimes as string.
I've added a data viewer so I can see how the columns are read as soon as SSIS reads the file.
When the cell in Excel is set as text its read correctly - I can then convert to a date as necessary
When the cell in Excel is set as date its read in US format! i.e. if it was 01/13/2014 in excel its read as 13/01/2014
How can I get round this? Its not an option to manually force the column to be text once exported from the system as my package picks this up automatically.
I have tried
-Regedit set typeguessrows = 0
-IMEX = 1 in connection string
-Set LocaleID = UK in the data flow task to read from Excel

I am reading a data source where all data in a given column is held as a string containing a percent value with 2 decimal points:
03.52%
12.32%
92.10%
80.05%
27.92%
100.00%
[...]
etc...
I need to convert these into decimal values with up to four decimal points, like this:
0.352
0.1232
0.9210
0.8005
0.2792
1.0000
I am trying to use the derived column editor but since I am fairly new to this, I am getting my wires crossed. c
1. Remove the % sign from the string -- not sure if I should use TRIM, or REPLACE
2. Divide the value by 100 -- but don't I need to do some sort of type casting first?
3. Do a cast to convert whatever I got into the correct decimals -- perhaps this isn't required if I did step 2 as a typecast to decimals already?

I have a stored proc that is being executed from an OLE DB Source component in my Data Flow. Takes one input parm, has several variables declared within, a derived table which is used in a join and all within a try catch block with transaction handling. No updates, just returning data, works great, except now I have been asked to replace these stored procs with inline queries.
ALTER PROCEDURE [dbo].[usp_Get_Test]
(
@numberOfMonthsint
)
AS
BEGIN
SET NOCOUNT ON
set transaction isolation level read uncommitted
[Code] ....
The problems I have run into so far are...
SQL command text in OLE DB Source Editor does not like:
- TRY/CATCH block
- Will not let me use my input parm (@numberOfMonths int)
- When I hard code in my input parm (select @BeginDate = dateadd(MONTH, -1, GETDATE())) I can parse query and run the step but no results are returned. So I am let to assume that it does not like the @TESTY derived table.
The query here as a sample has had pivots removed as well, but research suggests this should be an issue in the SQL command text.
Also, I know not even to try the Build Query... cause it will complain about any variable declarations (i.e., declare @BeginDate datetime).
For instance, can I pull this off with an Execute SQL Task? The problem is I don't see this available in the toolbox for the Data Flow.
Also, would my error handling be done in the Event Handlers tab now and if so, is there a good example of this?

Hi Gurus,
Here is my problem-:
I have a field in the SQL 2005 database with type varbinary(50). Now when i enter value to this field, I enter a value for example 111111101. The reason to enter such a value in varbinary(50) type is, that this value is meant to grow, as each 1 and 0 in this value is a permission or right my user would have to various features of the web application, I am designing. Now when I open the table to see the data in the database, it shows as <Binary data>. But that's okay, as binary fields are mostly meant to store pictures, files etc. But when I read this value into my ASP.Net code using c#, the value as returned as 069F6BBD. After some research I realized that for decimal value 111111101, the hex value is 069F6BBD.
All I need in my code is the same thing that I entered which is 111111101.
Can someone guide me a lil bit.
Thanks in advance..

Hi, I was wondering if any SQL Server gurus out there could help me...I have a table I'm trying to apply a full text catalog to, however no results are ever returned due to the text column being cataloged being of varbinary(max) that's being populated from a converted nvarchar(max) value - I've narrowed it down to this specifically, populating with non nvarchar text seems to work fine.To re-create the problem quickly...If I populate the column viaCONVERT(varbinary(max), 'test text')then there is no problem, I get results as expected.However if I populate the column viaCONVERT(varbinary(max), CAST('test text' as nvarchar(max)))no results are ever returned.Is this a bug with SQL Server 2005 Full Text Indexing? I'm happily creating full text catalogs when an nvarchar is not getting converted into a varbinary.I'm setting the Document Type column to '.html' (I've tried changing this to '.txt' in case it was a fault with the html ifilter but the problem persists so I believe I can rule this out).The reason I need to convert an nvarchar to varbinary is that the table holds multi-lingual text and I'm adding a html meta tag <META NAME="MS.LOCALE" CONTENT="ES"> to the beginning in order for the full text indexing word breaker to select the correct language to catalog the text with. The aim being to provide more relevant searches in users native languages (I've read a few articles that describe this technique, but it's the first time I've tried to apply it).Any pointers / suggestions would be greatly appreciated.

I have a very large database running in a production environment. The backup files are getting to be very difficult to manage. They are at 70gb as of now and growing at a rate of 10gb per month. This is due to document images being stored in the database in one table. I have read a little about a new feature in SQL Server 2012 called Filetable. Can we migrate to SQL Server 2012 and convert to the filetable structure, will this decrease the size of the backups? Would backup of the document images be taken care of by our nightly file system backups now?

I'm using SQL Server 2005. How can I convert a hex string to a varbinary or the opposite of that?
