String datatypes

The transformation string datatypes include Nstring, Ntext, String and Text. Although the Nstring, Ntext, String, and Text datatypes support the same precision up to 104,857,600 characters,

Data Integration

uses String to move string data from source to target and Text to move text data from source to target.

Because some databases store text data differently than string data,

Data Integration

needs to distinguish between the two types of character data. If the source displays String, set the target column to String. Likewise, if the source displays Text, set the target column to Text, Long, or Long Varchar, depending on the source.

In general, the smaller string datatypes, such as Char and Varchar, display as String in the source, Lookup transformation, and SQL transformation, while the larger text datatypes, such as Text, Long, and Long Varchar, display as Text in the source.

Use Nstring, Ntext, String, and Text interchangeably within transformations. However, in the source, Lookup transformation, and SQL transformation, the target datatypes must match. The database drivers need to match the string datatypes with the transformation datatypes, so that the data passes accurately. For example, Nchar in a lookup table must match Nstring in the Lookup transformation.
