As shown below, Connect CDC supports distribution of most Informix datatypes. In the tables of supported datatypes in the following pages, the Numeric Length column shows the maximum supported number of numeric digits, while Display Length is the maximum number of characters, or the numeric length plus an included sign, if any.
An asterisk (*) means the length is taken from the column definition in the DBMS catalog. For decimal numeric types, the length is the number of positions to the left of the decimal point. For example, a NUMERIC(10,2) column has a length of 8.
