formatShort

public static String formatShort(short myShort)

formatString

public static String formatString(String myString)

formatNull

public static String formatNull()

formatByte

public static String formatByte(byte myByte)

formatBoolean

public static String formatBoolean(boolean myBoolean)

formatDate

public static String formatDate(Date date,
                                TimeZone timeZone)

formatTime

public static String formatTime(Time time,
                                TimeZone timeZone)

formatTimestamp

public static String formatTimestamp(Timestamp time,
                                     TimeZone timeZone)

formatUUID

formatBigInteger

public static String formatBigInteger(BigInteger x)

formatLocalDate

public static String formatLocalDate(LocalDate x)

formatLocalDateTime

public static String formatLocalDateTime(LocalDateTime x)

formatLocalTime

public static String formatLocalTime(LocalTime x)

Formats a LocalTime as "HH:mm:ss". There isn't any dedicated ClickHouse data type for times, so this is the most straightforward thing to do. It would be wrong for the JDBC driver to construct an artificial DateTime representation using a dummy date, e.g. 1970-01-01.

Parameters:

x - a LocalTime parameter

Returns:

x formatted as "HH:mm:ss"

formatOffsetTime

public static String formatOffsetTime(OffsetTime x)

formatOffsetDateTime

public static String formatOffsetDateTime(OffsetDateTime x,
                                          TimeZone timeZone)

formatZonedDateTime

public static String formatZonedDateTime(ZonedDateTime x,
                                         TimeZone timeZone)

formatInstant

public static String formatInstant(Instant x,
                                   TimeZone timeZone)

formatBitmap

public static String formatBitmap(ClickHouseBitmap bitmap)

formatMap

public static String formatMap(Map<?,?> map,
                               TimeZone dateTimeZone,
                               TimeZone dateTimeTimeZone)

                                  TimeZone dateTimeZone,
                                  TimeZone dateTimeTimeZone)
