How to fix SQL ROUND not working?

Firstly, make sure you are using the ROUND function in the correct context. The ROUND function is typically used in queries to round the value of a numerical expression. Its syntax usually consists of ROUND(column_name, decimal_places).

If you are sure the grammar is correct but the ROUND function is not working, there could be several reasons for this.

1. Decimal Point Precision Issue: Ensure that you provide the correct number of decimal places. If a negative number of decimal places is provided, the ROUND function will return an integer. If the number of decimal places is 0, the ROUND function will return the nearest integer.
2. Issue with data types: Make sure the column being rounded is of a numeric type, such as integer, float, or decimal. If the column is a character type, the ROUND function will not work.
3. Database configuration issue: Some databases may have different rounding rules and settings. Make sure your database settings are suitable for the ROUND function. For example, in some databases, the default rounding rule may be “round down” instead of the common “round half up” rule.
4. Data issue: Make sure that your data contains significant figures that need to be rounded. If the number is already an integer or at the desired precision, the ROUND function will not make any changes.

If the above solutions still do not work, you can provide specific SQL query statements and database types in order for us to help you more effectively with resolving the issue.
