The the following storage types are defined in libgda:
null
bigint
biguint
binary
blob
boolean
date
double
geometric_point (point)
gobject
integer
list
money
numeric
single
smallint
smalluint
string
time
timestamp
tinyint
tinyuint
type
uinteger
unknown
Not all storage types are implemented (yet) and/or supported in all the various providers libgda can link with.
Within the ProLinga 4GL environment, only the basic data storage types are defined:
Character
Integer
Long (Integer)
Single (Precision Number)
Double (Precision Number)
Date
