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 }
For
more details see IBM Informix emulation parameters in FGLPROFILE.
