INT , UNSIGNED BIGINT ,
or NUMERIC
Adaptive Server IQ does not allow scaled integers, such as
INT(7,3). Data in the form INT(precision,scale) is converted to
NUMERIC (precision,scale). This differs from Adaptive Server
IQ versions prior to 12.0, and from Adaptive Server Enterprise,
in which
int datatypes can be values between -2,147,483,648
and 2,147,483,647, inclusive.
To handle larger integer values, you can use a BIGINT , an
unsigned integer ( UNSIGNED INT ), or an UNSIGNED BIGINT
datatype. With UNSIGNED INT , the last bit is used as part of the
value. There is no positive or negative indication; all numbers
are assumed to be positive, so the value can go up to
4,294,967,295.
numeric DECIMAL or NUMERIC
with appropriate precision
If the precision of the Adaptive Server IQdatatype you define
is too small to store the Adaptive Server Enterprise value, the
value converts to NULL.
decimal DECIMAL or NUMERIC
with appropriate precision
See above.
smallint SMALLINT or NUMERIC Adaptive Server IQ SMALLINT does not allow precision and
scale. Adaptive Server Enterprise smallint(precision,scale) is
converted to NUMERIC(precision,scale) See INT above.
tinyint TINYINT Adaptive Server IQ TINYINT columns do not allow precision
and scale. Adaptive Server Enterprise tinyint(precision,scale) is
converted to NUMERIC(precision,scale) . See INT above.

float (precision) FLOAT (precision) IQ supports greater precision for FLOAT
HNG indexes do not allow FLOAT , REAL , or DOUBLE data.
