Converting DataType=TEXT to DataType=STR

Hi,

I have an input text file which contains line(s) which can have more than 8000 characters.

I am able to read the lines in this file by specifying that the input column is data type = Text Stream [DT_TEXT] and I can then write the lines to another text file.

But, what I want to do is to use only the right-most 8000 characters. When I try to convert the input column to data type = String [DT_STR] using the Data Conversion transformation then I get the error:-

The conversion returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.

I cannot use the string manipulation functions e.g. RIGHT or SUBSTRING in a Derived Column transformation because these functions do not work with DT_TEXT data.
Any Ideas?!

Thanks.You'd only need *1* line of custom code in a Script component transformation to extract your rightmost 8000 characters before moving on to the data type conversion.

-Doug|||Thanks Doug ... Did you mean a Script Component which looks something like:-

Public Class ScriptMain

Inherits UserComponent

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)

Dim ascii As Text.Encoding

Dim asciiChars(10) As Char

ascii.GetChars(Row.InputColumn.GetBlobData(1, 1), 0, 1, asciiChars, 0)

Dim asciiString As New String(asciiChars)

MsgBox(asciiString)

End Sub

End Class

When I run the package it fails at the ascii.getchars line with the following error message:-

Error: 0xC0047062 at Data Flow Task, Script Component [106]: System.NullReferenceException: Object reference not set to an instance of an object.

All I am trying to do is extract the first byte and convert it to an ascii char (before I go on to work out the lengths to extract the right-most 8000 chars etc.)

Is this what you had in mind? Or, is there another way to do it?

Many Thanks.

|||This should do what you want. You will need to import System.Text.Encoding.

Dim Start As Integer = Max(0, CInt(Row.InputColumn.Length) - 8001)
Dim Length As Integer = Min(8000, CInt(Row.InputColumn.Length))
Dim asciiString As String = ASCII.GetString(Row.InputColumn.GetBlobData(Start, Length)

|||Just to confirm that Jay's suggestion works. Many Thanks.sqlsql

Convert MS Excel to XML and then insert all data records into MS SQL

Hi,

I am developing a web page for users to input data records. I am seeking the fastest way that users can upload their MS Excel files and the system can help data insertion into one data table. I know XML can insert data records into SQL database easily. Could any one give me some ideas how to perform this issue? Thanks a lot.

If you are using excel, you don't need to transform to xml. You can load data directly from excel file.

INSERT YourTable(...)

SELECT ...
FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:\YourExcelFile.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[YourSheetName]

|||

1) Save your excel file in XML format

2) create YourTable(xml_excel xml)

3) Run

INSERT YourTable(xml_excel)

select cast(x as xml) from openrowset(bulk 'dir_path_to_excel_xml_file', single_blob) as t(x)

|||

Thanks a lot! Could there be any sample code somewhere? I hardly find one suit into my case. The process should be:

1) Upload Excel file (Will be grateful if users can directly import.)

2) System Import data from specific data column in Excel to MS SQL table

A pre-define Excel workbook is provided for users.|||

I would like to convert the MS Excel file to XML on the server, rather than training users to export in XML format. Also, users may not all have Excel 2003.

Is there a way to convert on a server?

Thanks

Kenneth,

Another method is to use a third party tool, like the FarPoint Spread control (www.FarPointSpread.com) to load the Excel file on your web server, without needing access to Excel. Then, you have the data and formatting inspreadsheet format that you can do what you need to with. From here, I would suggest creating a DataSet object with the data and then opening a connection to the Sql database to write your DataRows from the DataSet you created.

Hi can u please tell me where this code should be written in an excel sheet.I am using macros to select data from sql and want to export the updated data from excel to sql database.

convert input parameter into field

create procedure [dbo].[findtext]
(
@.fieldname nvarchar(50),
@.searchtext nvarchar(50)
)
AS
SELECT * FROM tablename WHERE @.fieldname = @.searchtext
it doesn't work!Hi Joe,
Use dynamic SQL to build the SQL statement, something like this:
DECLARE @.sql nvarchar(200)
Set @.sql = 'SELECT * FROM tablename WHERE ' + @.fieldname + ' = ''' +
@.searchtext + ''''@.searchtext '''
EXEC(@.sql)

You will have to use dynamic SQL

since that could open you up to SQL injection attacks.
