# Data Types

The following data types are supported in Upsolver.

This type captures boolean values

`true`

and `false`

.A 64-bit signed two’s complement integer with a minimum value of

`-2^63`

and a maximum value of `2^63 - 1`

.A double is a 64-bit inexact, variable-precision implementing the IEEE Standard 754 for Binary Floating-Point Arithmetic.

A fixed precision decimal number. Precision is supported up to 18 digits.

The decimal type takes two literal parameters:

**precision**- total number of digits**scale**- number of digits in fractional part. Scale is optional and defaults to 0.

Example type definitions:

`DECIMAL(10, 3)`

, `DECIMAL(18)`

Example literals:

`DECIMAL '10.3'`

, `DECIMAL '1234567890'`

, `1.1`

Variable length of characters.

Calendar date (year, month, day).

Example:

`DATE '2001-08-22'`

Instant in time that includes the date and time of day without a time zone. Values of this type are parsed and rendered in the session time zone.

Example:

`TIMESTAMP '2001-08-22 03:04:05.321'`

Span of years and months.

Note that creating columns of this type are not supported. This is usually used when to create a time interval for filtering purposes.

Example:

`WHERE partition_date > DATE '2022-08-01' - INTERVAL '3' MONTH`

Span of days, hours, minutes, seconds and milliseconds.

Note that creating columns of this type are not supported. This is usually used when to create a time interval for filtering purposes.

Example:

`WHERE $commit_time BETWEEN run_start_time() - INTERVAL '2' DAY and run_end_time()`

An array of the given component type.

Note that arrays that only contain null values are treated as

`null`

; while for arrays that contain both null and non-null values, Upsolver ignores those null values when working with the array.Examples:

`ARRAY[1, 2, 3], [1, 2, 3]`
