ESQL/C data type constants

You assign the data type to a host variable in the program. The following table shows these constants.

Table 1. Constants for ESQL/C host-variable data types
ESQL/C data type	Constant	Integer value
char	CCHARTYPE	100
short int	CSHORTTYPE	101
int4	CINTTYPE	102
long	CLONGTYPE	103
float	CFLOATTYPE	104
double	CDOUBLETYPE	105
dec_t or decimal	CDECIMALTYPE	107
fixchar	CFIXCHARTYPE	108
string	CSTRINGTYPE	109
date	CDATETYPE	110
dec_t or decimal	CMONEYTYPE	111
datetime or dtime_t	CDTIMETYPE	112
ifx_loc_t or loc_t	CLOCATORTYPE	113
varchar	CVCHARTYPE	114
intrvl_t or interval	CINVTYPE	115
char	CFILETYPE	116
int8	CINT8TYPE	117
collection	CCOLTYPE	118
lvarchar	CLVCHARTYPE	119
fixed binary	CFIXBINTYPE	120
var binary	CVARBINTYPE	121
boolean	CBOOLTYPE	122
row	CROWTYPE	123

You can use these data types as arguments for some of the functions in the library. For example, both the rtypalign() and rtypmsize() functions require data type values as arguments.
