PL/SQL Variables Naming Convention - Shikshaglobe

When creating variables in PL/SQL, it is important to follow a naming convention in order to make your code more readable and easier to maintain. A good naming convention for variables is to use lowercase letters and underscores to separate words, for example: my_variable. Another convention that is sometimes used is to use CamelCase, where each word in the variable name is capitalized except for the first word, for example: MyVariable.In the Oracle PL/SQL programming language, variables can be either scalar (holding a single value) or composite (capable of holding multiple values). In either case, variables must be given a name before they can be used. According to the Oracle documentation, there are two main guidelines for naming PL/SQL variables:1. Variable names must begin with a letter (a-z, A-Z).2. Variable names can contain letters, numbers, and the underscore (_) character.There are also a few other restrictions on variable names: they cannot exceed 30 characters in length and they cannot be the same as any keywords in the PL/SQL language.Variables in PL/SQL can be named using any combination of letters, numbers, and the underscore character. However, there are a few rules and conventions that you should be aware of when choosing a name for your variables.First, variable names must begin with a letter. This is different from some programming languages, which allow variables to begin with an underscore character.Second, variable names can be no longer than 32 characters. This limit is imposed by the Oracle database.Third, variable names are case-insensitive. This means that the variable name MYVAR is the same as myvar. However, it is generally considered good programming practice to use all lowercase letters for your variable names.Finally, there are a few words that you cannot use as variable names because they are reserved for other purposes in PL/SQL. These words are:ALL ALTER AND ANY AS ASCWhen creating variables in PL/SQL, it is important to follow a naming convention in order to make your code more readable and understandable. The mostcommon naming convention is to use all lowercase letters for the variable names. Another popular convention is to use camel case, which means using both upper and lower case letters, with each new word beginning with a capital letter. For example, the variable name “employeeName” would be written as “EmployeeName” using camel case.
