Detailed Description

OCILIB encapsulates Oracle :

SQL timestamp data type within OCI_Timestamp structure
SQL interval data type within OCI_Interval structure

Basically, the OCI_Timestamp and OCI_Interval routines are wrappers around the Oracle OCIDatetime and OCIInterval APIs

Examples: #include "ocilib.h"

#define SIZE_STR 260

int main(void)

{

OCI_Timestamp *tm;

OCI_Interval *itv;

char str[SIZE_STR+1];

if (!OCI_Initialize(NULL, NULL, OCI_ENV_DEFAULT))

return EXIT_FAILURE;

tm = OCI_TimestampCreate(NULL, OCI_TIMESTAMP);

itv = OCI_IntervalCreate(NULL, OCI_INTERVAL_DS);

OCI_TimestampSysTimeStamp(tm);

OCI_TimestampToText(tm, "DD/MM/YYYY HH24:MI:SS:FF3", SIZE_STR, str, 3);

printf("%s\n", str);

OCI_IntervalSetDaySecond(itv, 1,1,1,1,0);

OCI_IntervalToText(itv, 10, 10, SIZE_STR, str);

printf("%s\n", str);

OCI_TimestampIntervalAdd(tm, itv);

OCI_TimestampToText(tm, "DD/MM/YYYY HH24:MI:SS:FF3", SIZE_STR, str, 3);

printf("%s\n", str);

OCI_Cleanup();

return EXIT_SUCCESS;

}
