Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025.
If you would like to use Python UDFs, create the UDFs prior to that date.
Existing Python UDFs will continue to function as normal. For more information, see the

STRTOL function
Converts a string expression of a number of the specified base to the equivalent integer value. The converted value must be within the signed 64-bit range.
Syntax
STRTOL(num_string, base)
Arguments
- num_string
-
String expression of a number to be converted. If num_string is empty (
''
) or begins with the null character ('\0'
), the converted value is0
. If num_string is a column containing a NULL value, STRTOL returnsNULL
. The string can begin with any amount of white space, optionally followed by a single plus '+

'. - base
-
INTEGER
between 2 and 36.
Return type
- BIGINT
-
If num_string is null, the function returns
NULL
.
Examples
To convert string and base value pairs to integers, use the following examples.
SELECT STRTOL('0xf',16);
