BOOLEAN data type
Informix®
Informix supports the BOOLEAN data type, which can store 't' or 'f'
values.
BOOLEAN data type in a different way: A
BOOLEAN variable stores integer values 1 or 0
(for TRUE or FALSE). This type is designed to hold the result of a
boolean expression.IBM® DB2®
IBM DB2 does not
provide a BOOLEAN SQL type.
Solution
The DB2 database interface converts
BOOLEAN type to CHAR(1) columns and stores '1' or
'0' values in the column.
The
BOOLEAN type translation can be controlled with the
following FGLPROFILE
entry:dbi.database.dsname.ifxemul.datatype.boolean = { true | false }
