I am using SSIS to create some packages. I have gotten confused around the Data Conversion Transformation component and changing columns data types from Advanced editor
If I can go into the advanced editor and change the data type of my output, why would I need to input the Data Conversion Transformation?
Is this just down to preference or is there a difference between using both approaches?
Before showing the difference between both approaches, i will try to give an overview of the data conversion types.
There are 2 different type of data type conversion:
From the following Microsoft Grid you can see what data types can be converted with each approach:
If you need to know what are the SSIS data types relevant to the data types of SQL Server database engine (mentioned in the Grid above), then you can refer to the following documentation:
Use the Data Conversion transformation to cast the data type of a column from one data type to a different data type
