DIGITS

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The DIGITS() function allows for turning numbers to 0-padded string that makes sorting those strings according to numeric values easier when concatenated to other strings. The padding depends on the number's data type, precision, and scale.

SELECT digits(cast(1234.5 as decimal(8, 2)));
create.select(digits(cast(val(1234.5), DECIMAL(8, 2)))).fetch();

The result being

+----------+
| digits   |
+----------+
| 00123450 |
+----------+

Dialect support

This example using jOOQ:

digits(cast(val(1234.5), DECIMAL(7, 2)))

Translates to the following dialect specific expressions:

Access

(replace(space(7 - len(cstr(cdec(abs((cdec(1.2345E3) * 100)))))), ' ', '0') & cstr(cdec(abs((cdec(1.2345E3) * 100)))))

ASE

(replicate(
  '0',
  (7 - char_length(CAST(CAST(abs((CAST(1.2345E3 AS decimal(7, 2)) * 100)) AS decimal(7)) AS varchar(7))))
) || CAST(CAST(abs((CAST(1.2345E3 AS decimal(7, 2)) * 100)) AS decimal(7)) AS varchar(7)))
