DATE

Syntax

DATE( expression [ , timezone ] )

Description

Warning

For ClickHouse data sources, numeric expression values less than or equal to 65535 are interpreted as the number of days (not seconds, like in all other cases) since January 1st 1970. This is the result of the behavior of available ClickHouse functions.

One way to surpass this is to use the following formula: DATE(DATETIME([value])). The result is more consistent, but is likely to be much slower.

Converts the expression expression to date format.

The date must be in the format YYYY-MM-DD.

If expression is a number, then the timezone option can be used to convert the date to the specified time zone.

Argument types:

  • expression — Date | Datetime | Fractional number | Integer | String
  • timezone — String

Return type: Date

Note

Only constant values are accepted for the arguments (timezone).

Note

Argument timezone is available only for ClickHouse sources.

Example

DATE("2019-01-23") = #2019-01-23#

Data source support

ClickHouse 21.8, Microsoft SQL Server 2017 (14.0), MySQL 5.7, Oracle Database 12c (12.1), PostgreSQL 9.3, YDB.
