Date Class
Summary of Date Methods
The following code example demonstrates a Date column value being retrieved
from the database, a bind using a Date object, and a computation using a
standalone Date object:
/* Create a connection */
Environment *env = Environment::createEnvironment(Environment::DEFAULT);
Connection *conn = env->createConnection(user, passwd, db);
/* Create a statement and associate a DML statement to it */
string sqlStmt = "SELECT job-id, start_date from JOB_HISTORY
where end_date = :x";
Statement *stmt = conn->createStatement(sqlStmt);
/* Create a Date object and bind it to the statement */
Date edate(env, 2000, 9, 3, 23, 30, 30);
stmt->setDate(1, edate);
ResultSet *rset = stmt->executeQuery();
/* Fetch a date from the database */
while(rset->next())
{
Date sd = rset->getDate(2);
Date temp = sd; /*assignment operator */
/* Methods on Date */
temp.getDate(year, month, day, hour, minute, second);
temp.setMonths(2);
IntervalDS inter = temp.daysBetween(sd);
.
.
.
}
