timeColumnMappingUsingSqlTime

@Deprecated
public static ColumnMapping timeColumnMappingUsingSqlTime()

Deprecated.

This method uses Time and the class cannot represent time value when JVM zone had forward offset change (a 'gap') at given time on 1970-01-01. If driver only supports LocalTime, use timeColumnMapping(io.trino.spi.type.TimeType) instead.

timeWriteFunctionUsingSqlTime

@Deprecated
public static LongWriteFunction timeWriteFunctionUsingSqlTime()

Deprecated.

This method uses Time and the class cannot represent time value when JVM zone had forward offset change (a 'gap') at given time on 1970-01-01. If driver only supports LocalTime, use timeWriteFunction(int) instead.

timeColumnMapping

public static ColumnMapping timeColumnMapping(TimeType timeType)

timeWriteFunction

public static LongWriteFunction timeWriteFunction(int precision)

timestampColumnMappingUsingSqlTimestamp

@Deprecated
public static ColumnMapping timestampColumnMappingUsingSqlTimestamp(TimestampType timestampType)

Deprecated.

This method uses Timestamp and the class cannot represent date-time value when JVM zone had forward offset change (a 'gap'). This includes regular DST changes (e.g. Europe/Warsaw) and one-time policy changes (Asia/Kathmandu's shift by 15 minutes on January 1, 1986, 00:00:00). If driver only supports LocalDateTime, use timestampColumnMapping() instead.

timestampColumnMapping

@Deprecated
public static ColumnMapping timestampColumnMapping()

Deprecated.

timestampColumnMapping

public static ColumnMapping timestampColumnMapping(TimestampType timestampType)

timestampReadFunction

public static LongReadFunction timestampReadFunction(TimestampType timestampType)

timestampWriteFunctionUsingSqlTimestamp

@Deprecated
public static LongWriteFunction timestampWriteFunctionUsingSqlTimestamp(TimestampType timestampType)

Deprecated.

This method uses Timestamp and the class cannot represent date-time value when JVM zone had forward offset change (a 'gap'). This includes regular DST changes (e.g. Europe/Warsaw) and one-time policy changes (Asia/Kathmandu's shift by 15 minutes on January 1, 1986, 00:00:00).

longTimestampWriteFunction

public static ObjectWriteFunction longTimestampWriteFunction(TimestampType timestampType)

toPrestoTimestamp

public static long toPrestoTimestamp(TimestampType timestampType,
                                     LocalDateTime localDateTime)

toLongTimestamp

public static LongTimestamp toLongTimestamp(TimestampType timestampType,
