    Sometimes your computer may display a message saying that converting between unicode and non-unicode is not a possible bug in ssis. This problem can have many causes. The only difference between Unicode and non-Unicode alternatives is whether the OAWCHAR type is char for character data files or char for personal data. Length arguments always specify a new number of characters, not a sequence of bytes.

    When data is transferred from one system to another, there are usually different types of data between and the split target cause. In this data warehouse task, the source is an nvarchar ray, and each of our targets is a varchar. The warehouse data creator decided to use a different data variant for performance reasons. The only issue in SQL Server Integration Services (SSIS) regarding this case becomes apparent only when the highly matched source column is actually stored as a target in a target OLE DB component column. Once

    If you create an OLE source in an SSIS database and add T-SQL for most of the data retrieval, the data type can be retrieved from the source table and also stored in the /exit input column properties. You can use the SSIS Conversion Data Component to convert a large nvarchar to varchar. But let’s consider another option for moving a data type. In this experiment, you will learn about the properties of I/O source components.

    This example table explores the products usedTransactions used in the AdventureWorks information and the Evidence Warehouse version of the Product Evaluation Table. You can download these lists from codeplex.

    Preparing a program is very simple. First, the hold table for a simple dimension is truncated. The data is then transferred to an intermediate table. The figure shows a SQL execution task (truncation of the intermediate table) and an additional data flow task (ordering the price measurement data).

    The data flow task in fig. 2 has a source OLE DB component that passes statistics to the target OLE DB component.

  • Simple T-SQL pass 3) for (original component image. OLE DB source is the component that defines columns 7 Production.Product which in SQL is a property of the with statement, not directly into the game. Since we only need these columns, 5 packages will work better if we practice and stick to best practices like T-SQL To make sure you are joining directly on a table, all columns will be SELECTed with *.Figure < /p> selected

    What is Unicode and non-Unicode in SQL?

    A single Unicode character takes more bytes to store all of the database input. On the other hand, non-Unicode code pages, as well as many other Asian languages, specify layout storage in double-byte character systems (DBCS). Therefore, for these languages ​​now there is almost no difference in storage, almost no Unicode and Unicode.

    Miscellaneous – T-SQL to collect products from source database.

    After tSince we decided to inject T-SQL into the original OLE DB component (Figure 4), the input data definitions from the source section are used to define each transform path to. In this position, nvarchar from production is used. The Product table can be used as a data type. Nvarchar evidence types are converted to a non-Unicode model in SSIS for input columns and results.

    In the table layout in fig. 5a uses the varchar data style for ProductName, ProductAlternativeKey, Color Size, and. nvarchar source. So if we 6)(map the content of this image to the SSIS service, we’ll get a nice error.

    CREATE TABLE dbo.stageProducts( [product id] integer, [product name] varchar(50), [ProductAlternateKey] varchar(25), [color] varchar(15), [ListPrice] money, [size] varchar(5), [ProductSubcategoryID] integer)

    After clicking OK, my error appears “ProductName column may not convert where the specified Unicode and non-Unicode string types come from”, as shown in Figure 1-3. 7.

    Now, instead of placing a data transformation component between the source and target components, T-SQL in all source components OLEDB is overridden to use the CAST function to finally convert source nvarchar columns to varchar. See fig. 8.

    SELECT [ProductID], CAST([Name] AS VARCHAR(50)) AS product name     ,CAST([ProductNumber] AS VARCHAR(25)) AS productalternatekey    ,CAST( [color] AS AS varchar(15)) color ,[list price]        ,CAST( [size] AS VARCHAR(5)) AS size         ,[Product Subcategory ID]  OUTPUT [Production].[Product]

    By placing a CAST to copy the nvarchar data type with “as varchar(xx)”, our custom component will cast the data to the appropriate channel. Considering that the data types were originally extracted from the original T-SQL, additional parameters of the original OLE DB component need to be changed. We need help to do it manually.

    Right-clicking the actual component on the source component (Fig. 9) activates a special menu for selecting Show in Advanced Editor…

    Once there, go to the input and output properties and just select the output columns. ProductName, Color productalternatekey, and Size should be changed from a Unicode string (DT_WSTR) to a string (DT_STR) as shown in the figure 10 and 11.

    After repeating the previous all nvarchar messages for this, the error disappears, as shown in Figure 12.

    How can I resolve the Unicode and non-Unicode data issue while importing Excel data into SQL Server?

    Select the product column for which you are looking for an error.Its data type must be “String[DT_STR]”.thisChange the data type so that String[DT_WSTR]” can use “unicode.

    While it is possible to find data bean conversion to convert data types, this method helps to keep the logic on top of T-SQL. Not only is this approach an alternative to data bean data conversion, but it also gives you the opportunity to learn about more advanced options of the original component.

    How do I convert Unicode to SSIS?

    We need to add the task of converting our SSIS data between the Excel source and these OLE DB targets. This converts the original Unicode data to non-Unicode. If you double-click the Transform item, your requirements can now tell it what you actually want to convert.
