The Developer tool treats the Uniqueidentifier data type as String. To move or change Uniqueidentifier data, connect the Uniqueidentifier column to a String column. To successfully move or change Uniqueidentifier data, ensure that the data is in the following format:

where

x

is a hexadecimal digit in the range 0-9 or a-f.

For example,

6F9619FF-8B86-D011-B42D-00C04FC964FF

is a valid Uniqueidentifier value.

The Developer tool can store 16 bytes of Uniqueidentifier data in 36 characters. However, since Uniqueidentifier data can be represented within two curly brackets, the Developer tool assigns two additional characters to the precision to accommodate the curly brackets. When you connect a Uniqueidentifier column to a String column, set the precision of the String column to 38 to successfully move or change Uniqueidentifier data.
