aws iot sql question

Yes, it is possible to convert hexadecimal numbers to decimal in AWS IoT SQL. Here is one way to do it:

Use the CAST function to convert the hexadecimal string to a BIGINT. This will interpret the hex string as a base 16 number and convert it to a decimal integer.

For example:

SELECT CAST('07e7' AS BIGINT) AS decimal_value

Would output:

decimal_value 2023

The CAST function handles strings of different lengths, so you can convert 1 byte hex values like '08' up to 8 byte values like '13a5'.

Some examples:

SELECT CAST('08' AS BIGINT) AS decimal_value

Would output:

decimal_value
8

SELECT CAST('19' AS BIGINT) AS decimal_value

Would output:

decimal_value 25

SELECT CAST('13a5' AS BIGINT) AS decimal_value

Would output:

decimal_value 5029
