In another case, while the expression statement returns a false value or in some situation to be NULL for the WHEN clause, it returns the else false statement. The next ELSE statement is not evaluated. The above syntax compares the given expression statement to value of WHEN clause and displays the first true statement after the successive comparison. This is the syntax for a single case when statement.ĬASE WHEN expression statement THEN ELSE END And below displays the generic form of Syntax. Nevertheless, the Ternary operator of SQL has a similar Case expression which is very flexible. This expression checks with each row in the table to meet the conditions true. Default component is SELECT in which CASE goes pretty well. IF(Statement expression, Result for true, result)Ĭase Expression: It is a simple statement with at least using One WHERE and THEN statements in the query and should end finally with END Statement. Based on the value of the respective condition is selected. Some versions would use case, if, when, then. There are two different cases where ternary operator logic can be implemented. Let’s see this topic in detail in the following Section. How does Ternary Operator works in SQL?Īs Ternary Operator Alternative is CASE Statement and IF (), Let’s Go with that. Where condition implies the expression when the condition is evaluated if the statement is true first statement will be executed.

(condition)? (First statement): (Second Statement) The basic Syntax of Ternary operator is given below: It comes with Select statement along with Where, Group By, Order By clause. It is called ternary as it takes three elements (condition, true statement and false statement) which takes one condition and produces two results true or False and it takes up any data type as a value. In other words, I can say that it is a shorthand way of using If-Else and nested if-else statement in a query. Case Expression can be expanded as a generalization of Ternary Operator. Ternary Operator in SQL also be termed as Conditional Operator can be defined as a unique decision-making operator found in many programming languages. A ternary operator with conditional expression performs real-life scenario like for different conditions different actions are performed. In this article, we will see how to use ternary Operator which is unfortunately not supported in SQL so then we are going to see an alternative of a conditional operator to work with SQL.
