Example 61 with LiteralParameters

use of io.trino.spi.function.LiteralParameters in project trino by trinodb.

the class VarcharToTimeWithTimeZoneCast method castToShort.

@LiteralParameters({ "x", "p" })
@SqlType("time(p) with time zone")
public static long castToShort(@LiteralParameter("p") long precision, ConnectorSession session, @SqlType("varchar(x)") Slice value) {
    checkArgument((int) precision <= MAX_SHORT_PRECISION, "precision must be less than max short timestamp precision");
    Matcher matcher = DateTimes.TIME_PATTERN.matcher(trim(value).toStringUtf8());
    if (!matcher.matches()) {
        throw new TrinoException(INVALID_CAST_ARGUMENT, "Value cannot be cast to timestamp: " + value.toStringUtf8());
    }
    try {
        long nanos = parseTime(matcher) * NANOSECONDS_PER_SECOND + parseFraction((int) precision, matcher, 9);
        nanos %= NANOSECONDS_PER_DAY;
        int offsetMinutes = parseOffset(session, matcher);
        return packTimeWithTimeZone(nanos, offsetMinutes);
    } catch (IllegalArgumentException e) {
        throw new TrinoException(INVALID_CAST_ARGUMENT, "Value cannot be cast to timestamp: " + value.toStringUtf8(), e);
