StandardSqlDataType

The data type of a variable such as a function argument. Examples include:

  • INT64: {"typeKind": "INT64"}

  • ARRAY:

{
  "typeKind": "ARRAY",
  "arrayElementType": {"typeKind": "STRING"}
}
  • STRUCT<x STRING, y ARRAY>:
{
  "typeKind": "STRUCT",
  "structType":
  {
    "fields":
    [
      {
        "name": "x",
        "type": {"typeKind": "STRING"}
      },
      {
        "name": "y",
        "type":
        {
          "typeKind": "ARRAY",
          "arrayElementType": {"typeKind": "DATE"}
        }
      }
    ]
  }
}
  • RANGE:
{
  "typeKind": "RANGE",
  "rangeElementType": {"typeKind": "DATE"}
}
JSON representation 
{
  "typeKind": enum (TypeKind),

  // Union field sub_type can be only one of the following:
  "arrayElementType": {
    object (StandardSqlDataType)
  },
  "structType": {
    object (StandardSqlStructType)
  },
  "rangeElementType": {
    object (StandardSqlDataType)
  }
  // End of list of possible types for union field sub_type.
}
Fields
typeKind

enum (TypeKind)

Required. The top level type of this field. Can be any GoogleSQL data type (e.g., "INT64", "DATE", "ARRAY").
Union field sub_type. For complex types, the sub type information. sub_type can be only one of the following:
arrayElementType

object (StandardSqlDataType)

The type of the array's elements, if typeKind = "ARRAY".
structType

object (StandardSqlStructType)

The fields of this struct, in order, if typeKind = "STRUCT".
rangeElementType

object (StandardSqlDataType)

The type of the range's elements, if typeKind = "RANGE".

TypeKind

The kind of the datatype.

Enums
TYPE_KIND_UNSPECIFIED Invalid type.
INT64 Encoded as a string in decimal format.
BOOL Encoded as a boolean "false" or "true".
FLOAT64 Encoded as a number, or string "NaN", "Infinity" or "-Infinity".
STRING Encoded as a string value.
BYTES Encoded as a base64 string per RFC 4648, section 4.
TIMESTAMP Encoded as an RFC 3339 timestamp with mandatory "Z" time zone string: 1985-04-12T23:20:50.52Z
DATE Encoded as RFC 3339 full-date format string: 1985-04-12
TIME Encoded as RFC 3339 partial-time format string: 23:20:50.52
DATETIME Encoded as RFC 3339 full-date "T" partial-time: 1985-04-12T23:20:50.52
GEOGRAPHY Encoded as WKT
NUMERIC Encoded as a decimal string.
BIGNUMERIC Encoded as a decimal string.
JSON Encoded as a string.
ARRAY Encoded as a list with types matching Type.array_type.
STRUCT Encoded as a list with fields of type Type.struct_type[i]. tabledata.list is used because a JSON object cannot have duplicate field names.
RANGE Encoded as a pair with types matching rangeElementType. Pairs must begin with "[", end with ")", and be separated by ", ".

StandardSqlStructType

The representation of a SQL STRUCT type.

JSON representation 
{
  "fields": [
    {
      object (StandardSqlField)
    }
  ]
}
Fields
fields[]

object (StandardSqlField)

Fields within the struct.
