Even though Oracle Database has a TO_CHAR(number) function that allows us to format numbers, it doesn’t provide a format element for the percentage sign.
Therefore, if we want to format a number as a percentage in Oracle Database, we need to concatenate the percentage sign and the number.
Here are two ways to format a number as a percentage in SQLite.
In SQLite, we can use the PRINTF() function or FORMAT() function to format numbers with leading zeros.
Azure SQL Edge uses a limited version of the SQL Server Database Engine. One of the limitations of Azure SQL Edge, is that it doesn’t currently support CLR-dependent T-SQL functions, such as the FORMAT() function.
This can be a problem when trying to format numbers.
However, there are often ways around such limitations. Here are examples of how we can pad numbers with leading and trailing zeros in SQL Edge.
MariaDB has the FORMAT() function, which formats a number based on the given format string.
It returns the number as a formatted string, with thousands and decimal separators in the appropriate position and rounds the result to the specified decimal position.
You can optionally specify a locale value to format numbers to the pattern appropriate for the given region.
In PostgreSQL, we can use the TO_CHAR() function to format numbers in a given format. This includes formatting numbers with commas in the relevant location.
PostgreSQL also has a money data type, which outputs the value using the current locale. This can include commas in the appropriate place, based on the locale being used.
