Data types
ThoughtSpot supports all the common data types. Before you import data, compare the data types you want to load from the source with the ones we support. Then, convert your data before loading it. Typically, you would export the data, transform it to meet these type rules, and then load the data. This is known as an extract-transform-load process.
Supported data types
The tables you create to receive the data must have the same number of columns and data types as the data you will be loading. Choose a data type for each column from the list of supported data types:
- Character or Text
-
VARCHAR(n)
Specify the maximum number of characters, as in
VARCHAR(255)
.The size limit is 64MB for
VARCHAR
values.If you have VARCHAR
data that exceeds the 64MB limit, the entire load fails.
- Floating point or Decimal
-
DOUBLE
orFLOAT
We recommend that you use
DOUBLE
, because it has a range of 15 significant digits,1.7E +/- 308
.FLOAT
has a range of 7 significant digits,3.4E +/- 38
.
- Boolean
-
BOOL
Can be
true
orfalse
.
- Integer
-
INT
orBIGINT
INT
holds 32 bits. It has a range of-2,147,483,648
to2,147,483,647
.BIGINT
holds 64 bits. It has a range of-9,223,372,036,854,775,808
to9,223,372,036,854,775,807
.
- Date or time
-
DATE
,DATETIME
,TIMESTAMP
, orTIME
ThoughtSpot stores
DATETIME
,TIMESTAMP
, andTIME
at the granularity of seconds.TIMESTAMP
is identical toDATETIME
; we include it for syntax compatibility.
Geographical data types
ThoughtSpot supports geographical data.
How to import geographical data
Import your geographical data as text values. This ensures that the data defaults to the correct configuration, where the data type is VARCHAR
.
You can use DOUBLE
or VARCHAR
for latitude and longitude data. See the following example:
Here, the zipcodes were imported as text values. By default, the data type
is VARCHAR
, the column type
is attribute
, and additive
is no
.
|
Latitude and longitude
For latitude and longitude, you can use either VARCHAR
or DOUBLE
.
Latitude and longitude data must be in the form of positive and negative numbers, most commonly decimals, NOT in degree / minute / second notation. North of the Equator, latitude values are positive, and south of the Equator, latitude values are negative. East of the Prime Meridian, longitude values are positive, and West of the Prime Meridian, longitude values are negative. |
Designate geographical data
After loading the data, designate it as a geographical data type when you Edit the system-wide data model.
|
These data types can be designated as geographical data, which enables them to be visualized using the Geo chart types:
-
Sub-nation region, such as State, County, Zip Code, Province, Prefecture, District, and so on.
- Country
-
Countries, such as United States:
