dateColumnMappingUsingSqlDate

@Deprecated
public static ColumnMapping dateColumnMappingUsingSqlDate()

Deprecated.

This method leads to incorrect result when the date value is before 1582 Oct 14. If driver supports LocalDate, use dateColumnMappingUsingLocalDate() instead.

dateReadFunctionUsingSqlDate

@Deprecated
public static LongReadFunction dateReadFunctionUsingSqlDate()

Deprecated.

If driver supports LocalDate, use dateReadFunctionUsingLocalDate() instead.

dateWriteFunctionUsingSqlDate

@Deprecated
public static LongWriteFunction dateWriteFunctionUsingSqlDate()

Deprecated.

If driver supports LocalDate, use dateWriteFunctionUsingLocalDate() instead.

dateColumnMappingUsingLocalDate

public static ColumnMapping dateColumnMappingUsingLocalDate()

dateReadFunctionUsingLocalDate

public static LongReadFunction dateReadFunctionUsingLocalDate()

dateWriteFunctionUsingLocalDate

public static LongWriteFunction dateWriteFunctionUsingLocalDate()

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)

timeReadFunction

public static LongReadFunction timeReadFunction(TimeType timeType)

timeWriteFunction

public static LongWriteFunction timeWriteFunction(int precision)

timestampColumnMappingUsingSqlTimestampWithRounding

@Deprecated
public static ColumnMapping timestampColumnMappingUsingSqlTimestampWithRounding(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). This mapping also disables pushdown by default to ensure correctness because rounding happens within Trino and won't apply to remote system. If driver supports LocalDateTime, use timestampColumnMapping(io.trino.spi.type.TimestampType) instead.

timestampColumnMapping

public static ColumnMapping timestampColumnMapping(TimestampType timestampType)

timestampReadFunction

public static LongReadFunction timestampReadFunction(TimestampType timestampType)

longTimestampReadFunction

public static ObjectReadFunction longTimestampReadFunction(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). If driver only supports LocalDateTime, use timestampWriteFunction(io.trino.spi.type.TimestampType) instead.
