​
Parameters

<value>The value to convert or an expression that results in a value to convert.Any

Example

The following example returns 1 as an integer: 
SELECT CAST('1' AS INTEGER) AS level;
level int
1

Rows: 1Execution time: 4.93ms

CAST can also be done by writing the format before the object, for example - SELECT DATE '2022-01-01' , SELECT TIMESTAMP '2022-01-01 01:02:03'.
CAST can also be done by using the :: operator. For more information, see :: operator for CAST.
