Context functions¶

This family of functions allows for the gathering of information about the context in which the statement is executed. These functions are evaluated at most once per statement.

Usage notes¶

Context functions generally do not require arguments.
To comply with the ANSI standard, the following context functions can be called without parentheses in SQL statements:
- CURRENT_DATE
- CURRENT_TIME
- CURRENT_TIMESTAMP
- CURRENT_USER
- LOCALTIME
- LOCALTIMESTAMP
Note

If you are setting a Snowflake Scripting variable to an expression that calls one of these functions (for example, my_var := <function_name>();), you must include the parentheses.

Examples¶

Display the current warehouse, database, and schema for the session:

SELECT CURRENT_WAREHOUSE(), CURRENT_DATABASE(), CURRENT_SCHEMA();

Copy

+---------------------+--------------------+------------------+
| CURRENT_WAREHOUSE() | CURRENT_DATABASE() | CURRENT_SCHEMA() |
|---------------------+--------------------+------------------+
| MY_WAREHOUSE        | MY_DB              | PUBLIC           |
|---------------------+--------------------+------------------+

Display the current date, time, and timestamp (note that parentheses are not required to call these functions):

SELECT CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP;

Copy

+--------------+--------------+-------------------------------+
| CURRENT_DATE | CURRENT_TIME | CURRENT_TIMESTAMP             |
|--------------+--------------+-------------------------------|
| 2024-06-07   | 10:45:15     | 2024-06-07 10:45:15.064 -0700 |
+--------------+--------------+-------------------------------+

In a Snowflake Scripting block, call the CURRENT_DATE function without parentheses to set a variable in a SQL statement:

EXECUTE IMMEDIATE
$$
DECLARE
  currdate DATE;
BEGIN
  SELECT CURRENT_DATE INTO currdate;
  RETURN currdate;
END;
$$
;

Copy

+-----------------+
| anonymous block |
|-----------------|
| 2024-06-07      |
+-----------------+

In a Snowflake Scripting block, attempting to set a variable to an expression that calls the CURRENT_DATE function without parentheses results in an error:

EXECUTE IMMEDIATE
$$
DECLARE
  today DATE;
BEGIN
  today := CURRENT_DATE;
  RETURN today;
END;
$$
;

Copy

000904 (42000): SQL compilation error: error line 5 at position 11
invalid identifier 'CURRENT_DATE'

The same block returns the current date when the function is called with the parentheses:

EXECUTE IMMEDIATE
$$
DECLARE
  today DATE;
BEGIN
  today := CURRENT_DATE();
  RETURN today;
END;
$$
;

Copy

+-----------------+
| anonymous block |
|-----------------|
| 2024-06-07      |
