How to interpret the DBINFO entry in the data dictionary file

Problem or error: What does the DBINFO entry in the data dictionary (.dct file) mean?

Solution: The DBINFO entry stores field definition information from the database. When creating a new table in the same database, Campaign uses the DBINFO values to create the table with the correct field definitions.

The DBINFO definition is:

(Source type / native type / data type / precision / scale)

Unica does not support any customer modifications to the DBINFO fields.

Here is a sample .dct file.

CUSTID, ASCII string, 25, 0, DBINFO(1/1/17/-2147483647/-2147483647),
