How to Convert SQL Float Values from Scientific Notation to Normal String Format

Attempting to change a SQL float column from scientific notation to a regular string format. My conversion attempt fails. For example:

UPDATE RecordsTable
SET StrValue = CONVERT(varchar(15), CAST(NumValue AS decimal(15,2)))
WHERE NumValue IS NOT NULL;
2

In my experience, the behavior of converting floats to strings with a specific formatting might vary between SQL Server versions. I ran into a similar issue and solved it by using the built-in STR() function instead of CONVERT. For example, I updated my query to construct the string directly with an appropriate precision: UPDATE RecordsTable SET StrValue = LTRIM(STR(NumValue, 15, 2)) WHERE NumValue IS NOT NULL. This method neatly handles the trailing spaces and converts the numbers without using scientific notation. It is important to adjust the parameters to match the expected width and decimals.
