SQL Datum Formatting

SQL Datum Formatting refers to the process of converting data in different formats into a standard format, which can be easily understood and managed by SQL queries.

Data formatting is an essential part of the data extraction and analysis process in SQL. It helps minimize errors, enhances data accuracy, and improves query performance.

Date Formatting

Dates are one of the most commonly formatted data types in SQL. To format a date, use the CAST or CONVERT function. The following code demonstrates formatting a date in ISO format:

--------------
14:10:10

Currency Formatting

Currency formatting refers to the process of converting numeric values into currency format with proper symbols and decimal points. The following code formats a currency value with the FORMAT function:

SELECT FORMAT(1234567, 'C0') AS 'Formatted Currency';

Output:

Formatted Currency
------------------
$1,234,567
