In SQL Server, you can use the
FORMAT function or the
CONVERT functions to display a specific number of digits after the decimal point. Here’s how you can do it:
Using the FORMAT Function:
FORMAT function allows you to format values in various ways, including specifying the number of decimal places.
SELECT FORMAT(column_name, 'N2') AS formatted_number
In this example,
column_name is the column you want to format, and
'N2' specifies that you want to format the number with two digits after the decimal point.
Using the CAST or CONVERT Functions:
You can also use the
CONVERT functions along with the
DECIMAL data type to achieve the same result.
SELECT CAST(column_name AS DECIMAL(10, 2)) AS formatted_number
SELECT CONVERT(DECIMAL(10, 2), column_name) AS formatted_number
In both examples,
10 represents the total number of digits in the number (including digits before and after the decimal point), and
2 represents the number of digits after the decimal point.
column_name with the actual column name from your table and
your_table with the actual table name you’re working with.
Remember to adjust the data type and precision (the first parameter in the
DECIMAL type) according to your needs and the existing data type of the column.
