SQL Server has many different data types and it is not always a given as which data type to use, so this outline gives you a quick overview of the different data types you can use in SQL Server. Solution Following are commonly used data types organized by category with a brief description...
Theintdata type is the primary integer data type in SQL Server. Thebigintdata type is intended for use when integer values might exceed the range that is supported by theintdata type. bigintfits betweensmallmoneyandintin the data type precedence chart. ...
In large-scale applications with a massive influx of data, an integer-based identifier might approach its positive limit faster than anticipated. One approach to circumvent this limitation, without immediately switching to theBIGINTdata type, is to utilize the negati...
