Proc Sql Case When Else End

If no conditions are true it returns the value in the else clause.

Proc sql case when else end. If no else expression is present and every when condition is false the result of the case expression is a missing value. If every when condition is false then proc sql executes the else expression and its result becomes the case expression s result. If there is no else part and no conditions are true it returns null.

If every when condition is false then proc sql executes the else expression and its result becomes the case expression s result. If every when condition is false proc sql executes the else expression and its result becomes the case expression s result. If no else expression is present and every when condition is false then the result of the case expression is a missing value. If no else expression is present and every when condition is false then the result of the case expression is a missing value.

However the begin end is required for the if else statements while statements etc where you need to wrap multiple statements. The sql case statement. If no else expression is present and every when condition is false then the result of the case expression is a missing value. A missing value is assigned to a case expression when an else expression is not specified and each when condition is false.

You can use a case expression as an item in the select clause and as either operand in an sql expression. We often use the begin end at the start and end of a stored procedure and function. Every value that s greater than 1 05 turns to 1 05 but everything else turns to. If every when condition is false then proc sql executes the else expression and its result becomes the case expression s result.

The case statement goes through conditions and returns a value when the first condition is met like an if then else statement. Points case when points 1 05 then end as newpoints. When i run the code above i get kind of close. So once a condition is true it will stop reading and return the result.

But it is not strictly necessary. You can use case expressions in the select update and insert statements.
