What is the Difference Between if and if else?

The difference between an "if" statement and an "if else" statement lies in the structure and execution of the code based on the condition. Here are the key differences:

1. If statement: The if statement is executed if the condition inside the test evaluates to true. If the condition is false, the statements inside the if block are skipped, and the next statement after the if block is executed.

   if (condition) {
       // statements executed if the condition is true
   }

2. If else statement: The if else statement has an additional "else" block. If the condition inside the test is true, the block of code inside the if statement is executed. If the condition is false, the block of code inside the else statement is executed.

   if (condition) {
       // statements executed if the condition is true
   } else {
       // statements executed if the condition is false
   }

In summary, the if statement only executes the code inside the if block if the condition is true, while the if else statement provides an alternative block of code to execute if the condition is false.

Comparative Table: if vs if else

The main difference between "if" and "if else" control structures lies in how they handle the condition. Here is a table summarizing the differences:

In the context of SQL, the "IF" statement is used to control the flow and decide what has to be evaluated next, based on the condition. On the other hand, the "CASE" statement is a function that checks the condition and returns a value based on the result.
