The value type in Scala of the data type of this field(For example, Int for a StructField with the data type IntegerType) Also, two fields with the same name are not allowed. Note: The default value of valueContainsNull is true. Note: The default value of containsNull is true. nullable is used to indicate if values of these fields can haveįind full example code at "examples/src/main/scala/org/apache/spark/examples/sql/SparkSQLExample.scala" in the Spark repo. The data type of a field is indicatedīy dataType. The name of a field is indicated by name. StructField(name, dataType, nullable): Represents a field in a StructType.StructType(fields): Represents values with the structure described by.Is used to indicate if values of a MapType value can have null values. The data type of keys isĭescribed by keyType and the data type of values is described by valueType.įor a MapType value, keys are not allowed to have null values. Represents values comprising a set of key-value pairs. MapType(keyType, valueType, valueContainsNull):.containsNull is used to indicate ifĮlements in a ArrayType value can have null values. ArrayType(elementType, containsNull): Represents values comprising a sequence ofĮlements with the type of elementType.INTERVAL '100 10:30:40.999999' DAY TO SECONDĭayTimeIntervalType(HOUR, HOUR) or DayTimeIntervalType(HOUR)ĭayTimeIntervalType(MINUTE, MINUTE) or DayTimeIntervalType(MINUTE)ĭayTimeIntervalType(SECOND, SECOND) or DayTimeIntervalType(SECOND) Supported day-time interval types are: Day-Time Interval TypeĭayTimeIntervalType(DAY, DAY) or DayTimeIntervalType(DAY) Valid values of startField and endField are 0 (DAY), 1 (HOUR), 2 (MINUTE), 3 (SECOND). StartField is the leftmost field, and endField is the rightmost field of the type. SECOND, seconds within minutes and possibly fractions of a second ,. ![]() DayTimeIntervalType(startField, endField): Represents a day-time interval which is made up of a contiguous subset of the following fields:.YearMonthIntervalType(MONTH, MONTH) or YearMonthIntervalType(MONTH) YearMonthIntervalType(YEAR, YEAR) or YearMonthIntervalType(YEAR) Supported year-month interval types are: Year-Month Interval Type Valid values of startField and endField are 0(MONTH) and 1(YEAR). Individual interval fields are non-negative, but an interval itself can have a sign, and be negative. YearMonthIntervalType(startField, endField): Represents a year-month interval which is made up of a contiguous subset of the following fields:.DateType: Represents values comprising values of fields year, month and day, without a.Hour, minute, and second, with the session local time-zone. ![]() TimestampType: Represents values comprising values of fields year, month, day,.BooleanType: Represents boolean values.BinaryType: Represents byte sequence values.Char type column comparison will pad the short one to the longer length. Reading column of type CharType(n) always returns string values of length n. CharType(length): A variant of VarcharType(length) which is fixed length.Note: this type can only be used in table schema, not functions/operators. Data writing will fail if the input string exceeds the length limitation. VarcharType(length): A variant of StringType which has a length limitation.StringType: Represents character string values. ![]() A BigDecimal consists of an arbitrary precision integer unscaled value and a 32-bit integer scale.
