If data has a data type that is not convertible to an Integration Services data type, an error occurs. Some data flow components convert data types between the Integration Services data types and the managed data types of the Microsoft.
NET Framework. For more information about the mapping between Integration Services and managed data types, see Working with Data Types in the Data Flow.
The following table lists the Integration Services data types. Some of the data types in the table have precision and scale information that applies to them. If the data in a column does not require the full width allocated by the source data type, you might want to change the data type of the column.
Making each data row as narrow as possible helps optimize performance when transferring data because the narrower each row is, the faster the data is moved from source to destination. Integration Services includes a complete set of numeric data types, so that you can match the data type closely to the size of the data.
Use an expression to implicitly convert data types. Use the cast operator to convert data types. Use the Data Conversion transformation to cast the data type of a column from one data type to a different data type. For more information, see Data Conversion Transformation. Use the Derived Column transformation to create a copy of a column that has a different data type than the original column. For more information, see Derived Column Transformation.
When you use the cast operator or the Data Conversion transformation, the date or time type data type will be converted to the corresponding string format. When you want to convert from a string to a date or time data type, the string must use the string format that corresponds to the appropriate date or time data type.
There is a space between the time element and the time zone element. The following table provides guidance on mapping the data types used by certain databases to Integration Services data types. These mappings are summarized from the mapping files used by the SQL Server Import and Export Wizard when it imports data from these sources.
These mappings are not intended to represent strict equivalency, but only to provide guidance. In certain situations, you may need to use a different data type than the one shown in this table. You can use the SQL Server data types to estimate the size of corresponding Integration Services date and time data types. For information on mapping data types in the data flow, see Working with Data Types in the Data Flow. You jump right in.
Give some back ground to what your environment is, what you are trying to do at the begining, and clearly state what you are asking. I suspect my question is a bit technical.
It deals with direct access to OleDB, not high-level access. I highlighted the issue I want to fix by putting it in bold, updated the source code, and asking a direct question in the last paragraph. Hope it's easier to understand. I will admit, I hardly skimmed over it, it was long, no clue how to answer it, no idea what you are even talking about, and have never written a line of Delphi ever. I have made offense where I meant none. I am Ashamed. Add a comment. Active Oldest Votes.

The column expression is one of the values you define when we use the Derived Column transformation to create a column.
Figure 5 shows how to configure the other values. As the figure shows, a new column named NewProdID is being added to the data flow. However, you might want to first verify the columns in your data flow. When you open the editor, go to the Metadata page, as shown in Figure 6. As you can see, all columns and their data types are listed in the editor.
That includes the two columns that have been converted, both before and after that conversion. If precision and scale are factors in any of your columns, those too are included. As you can see, not all the SSIS types correlate directly to those of the target columns. When you retrieve or load data, SSIS tries to automatically convert it to the correct types. For the most part, however, you should find that the SSIS types provide you with the versatility you need to retrieve data from a variety of sources and load it into a variety of destinations.

The data types supported by SSIS can be divided into the following categories: Numeric : Types that support numeric values formatted as currencies, decimals, and signed and unsigned integers.
SSIS supports more numeric types than any other kind. Binary : Types that support binary and image values. Boolean : A type to handle Boolean values. USE AdventureWorks ;. AWProducts ;. ProductID ,. Name ,.
