Unicode Vs Non Unicode Ssis
to vote Yes, string fields in Excel are treated as Unicode string fields by the driver. Here is some content written about moving data in the other direction that applies here too:Data types. The Excel driver uses only six data types, which Integration Services maps as follows: Numeric – double-precision float (DT_R8) Currency – currency (DT_CY) Boolean – Boolean (DT_BOOL) Date/time ole db source cannot convert between unicode – date (DT_DATE) String – Unicode string, length 255 (DT_WSTR) Memo – Unicode text stream (DT_NTEXT) Data type and length conversions. The Excel driver recognizes only a limited set of data types, as listed above. For example, all numeric columns are interpreted as doubles (DT_R8), and all string columns (other than memo columns) are interpreted as 255-character Unicode strings (DT_WSTR). Integration Services does not implicitly convert data types. As a result, you may need to use Derived Column or Data Conversion transformations to convert Excel data explicitly before loading it into non-Excel destinations. In this case, it may be useful to create the initial package by using the Import and Export Wizard, which configures the necessary conversions for you. Some examples of the conversions that may be required include the following: From Unicode Excel string columns to non-Unicode destination string columns with specific codepages From 255-character Excel string columns to shorter destination string columns From double-precision Excel numeric columns to integer destination columns Thursday, July 28, 2005 10:18 PM Reply | Quo

In other words the source column should be DATETIME column and the excel column should be a DATE format too. This should help you avoid the regional/locale issues that rear their head so often in ETL.HTH Kindest Regards,Frank Bazan Post #770955 Mahesh BoteMahesh Bote Posted Monday, February 1, 2016 1:18 AM Ten Centuries Group: General Forum Members Last Login: Monday, August 29, 2016 8:08 AM Points: 1,104, Visits: 1,274 Or even what you can try is, making a use of "DATA CONVERSION" Transformation.

VARCHAR fields. Usually, project managers and lazy team leads make simple decision of using Unicode (NVARCHAR) for SQL Server fields. As a result, Accounts, Social Security http://slavasql.blogspot.com/2015/08/ssis-conversion-from-unicode-to-non.html Numbers, and all other 100% non-unicode character fields take double space on https://forums.asp.net/t/1896979.aspx?Error+at+Data+Flow+Task+OLE+DB+Destination+36+Column+Name+cannot+convert+between+unicode+and+non+unicode+string+data+types disk and in memory. Their arguments are simple: It is easier/faster/cheaper to have all unicodes, than deal with unicode conversion problems. As a SQL Server consultant, who makes money on performance troubleshooting, I appreciate their intention to make their databases and SQL Server slower. That might be my place of work error at in the future to make their system more reliable and faster. However, as Database architect I have to make sure that all columns have appropriate data type and that data type uses minimum storage. For that purpose I have to do conversion of unicode strings to non-unicode. In this blog post for simplicity I will use SQL server as a data source, but it error at data can be MySQL, Oracle, Text or Excel file or anything else. Disclaimer: In my assumption, if you are reading this blog you have pretty good SSIS skills and I do not have to explain how to create a package, data flow task, connection and add script component to your task. Preparation. At first, in TestDB database (NON-PRODUCTION) we will create source table "tbl_Test_Unicode", target table "tbl_Test_NonUnicode" and insert some bad data into the source: USE TestDB GO CREATE TABLE tbl_Test_Unicode(UColumn NVARCHAR(10)); GO CREATE TABLE tbl_Test_NonUnicode(NUColumn VARCHAR(10)); GO INSERT INTO tbl_Test_Unicode(UColumn) SELECT N'ABC' + CAST(0xC296 AS NVARCHAR) + N'DEF'; GO SELECT * FROM tbl_Test_Unicode GO As a result of that script we will see following: Then will create Simple SSIS package with only one data flow task: Problem 1. Will create OLE DB Source and OLE DB Destination for tables "tbl_Test_Unicode" and "tbl_Test_NonUnicode": As you can see we immediately have a problem: "Validation error. Data Flow Task 1: Data Flow Task 1: Columns "UColumn" and "NUColumn" cannot convert between unicode and non-unicode string data types." That was expected and we will easily solve that problem: Problem 2. We solve pro
