Supported Datatypes for Message Flow

RAP supports the following datatypes for message flow.

Supported datatypes for message flow

RDS datatype

Adaptive Server datatype

Sybase IQ datatype

uint8

tinyint

tinyint

uint16

unsigned smallint

unsigned int (IQ has no unsigned smallint)

uint32

unsigned int

unsigned int

uint64

unsigned bigint

unsigned bigint

sint8

smallint (Adaptive Server has no signed 8-bit integer)

smallint (IQ has no signed 8-bit integer)

sint16

smallint

smallint

sint32

int

int

sint64

bigint

bigint

decimal( p, s )

numeric( p, s ) or decimal( p, s )

Limited to precision 38. Precision must be the same on RAPCache and RAPStore.

numeric( p, s ) or decimal( p, s )

Limited to precision 38. Precision must be the same on RAPCache and RAPStore.

datetime

datetime for granularity to 1/300th of a second

timestamp

datetime2

bigdatetime for granularity to 6 decimal places

timestamp

date

date

date

time

time

time

time2

bigtime for granularity to 6 decimal places

timestamp

string

char(n) or varchar(n) n <255*

char(n) or varchar(n) n <255*

Note:
  • If you know that data for a column is always going to be shorter than a specific length, set n to a small as possible value for better performance.

  • For precisions up to 18 digits (approximately), to gain maximum performance , use pub_setDecimalFieldFromMantissa instead of pub_setDecimalto set decimal fields, if you can obtain the desired value in a format other than double precision.

  • For precisions up to 38, use pub_setDecimalFieldFromString to set decimal fields.
  • For RAPCache microsecond time granularity, as supported in RAPStore, your application must use the bigdatetime and bigtime datatypes that support it. When using these datatypes, you must use the pub_setDateTime2Field and pub_setTime2Field methods which operate on these types.
