​
Base
​
kind
string
The resource type. Will always be "variable".
uri
string
The fully qualified reference to this upload, for use in generating calls to this API. 
For example, /tables/imathews.example:123.test:456/variables/var1
url
string
The variable's discoverable url through a web browser interface.
name
string
The variable's name. Will always be unique to the variable's table.
type
string
The variable's type. Will be one of: 
"boolean","integer","float","string","date","dateTime"
index
integer
A zero based counter for the variable's ordinality for its table.
label
string
A user-provided label for the variable. May be null.
Get
​
description
string
A user-provided description for the variable, typically longer than the label. May be null.
valueLabels
array<object>
An array of value labels. Value labels are used to provide mappings between the data content of a cell and human-readable meaning of that content.
valueLabels.value
string
The value associated with a given valueLabel
valueLabels.label
string
The human-readable label for the associated value.
statistic
object
An object containing univariate summary statistics about the variable.
​
If the statistics have not yet been computed on the variable, statistic.status will running and many (or all) of the statistic fields will be missing until status is completed.
statistic.status
string
The current status of the statistic's computation. Will be one of completed, running, or failed. If the statistic is failed, it can only be recomputed in the UI.
statistic.count
string(int64)
The number of non-null values for this variable. 
statistic.numDistinct
string(int64)
The number of distinct values for this variable.
statistic.min
number|string(int64)
The minimum value of this variable. 

Will be null for variables of string and boolean type. For integers, will be a string(int64). For all other variable types this will be a number.
​
If the variable is of type date or dateTime, this number represents the number of milliseconds since the epoch (1970-01-01). If the variable is of type time, this number represents the number of milliseconds since 00:00:00.
statistic.max
number|string(int64)
The maximum value of this variable. 

See statistic.min for information about different variable types.
statistic.mean
number|string(int64)
The average value of this variable. 

See statistic.min for information about different variable types.
statistic.approxMedian
number|string(int64)
The approximate median of this variable. Uses the BigQuery APPROX_QUANTILES function.​
​
See statistic.min for information about different variable types.
statistic.stdDev
number
The sample (unbiased) standard deviation of this variable.

Will be null for variables of string and boolean type. For all other variable types this will be a number.
​
If the variable is of type date , time, or dateTime, this number measures the standard deviation in milliseconds.
