SQL Server CASE Statement And CASE WHEN Examples

About Proc Sql

I ran the below to create a computed column and everything worked fine. I then tried to edit this same code in working with data in different data set requiring multiple conditions to be met - meaning when x 1 and y 1 and z 1 and aa 1, then the computed column quotWorkquot but having trouble. How t

The following two PROC SQL steps show two equivalent CASE expressions that create a character column with the strings in the THEN clause. The CASE expression in the second PROC SQL step is a shorthand method that is useful when all the comparisons are with the same column.

I'm using proc sql, and using multiple case when statements to add columns with either a 0 or 1 if the condition is met. It's a big bottleneck right now since it has to scan through each id for eac

This paper presents the power, and simplicity, of using case expressions to perform conditional processing in the SQL procedure. Two forms of case expressions will be illustrated for users to consider when confronted with conditional logic scenarios simple and searched along with brief explanations, guidelines and quotsimplequot coding techniques.

The CASE WHEN statement in SAS is a powerful and convenient tool used to control the flow of a program by allowing you to apply different conditions to a statement. This statement evaluates an expression and returns a result depending on the condition. It is similar to an IF-THEN-ELSE statement, except with CASE WHEN, you can use multiple conditions and you can specify different results for
