Proc sql max case

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. Would appreciate some help with my syntx.

Solved: Hello all- Hope everybody had a good holiday! I have two tables (A) and (B). Oklahoma State University Yu Fu. Thank you for your suggestions, allan.

Now MAX ( CASE ) is working correctly. Now the problem is that the column name in the MAX sentence is not working. When storing a value in a single macro variable, PROC SQL preserves leading or trailing blanks.

The TRIMMED option can be used to trim the leading and trailing blanks from values that are stored in a single macro variable. Conditional sum using proc sql. Ask Question Asked years, months ago. In this case , either a PROC FREQ or better PROC TABULATE would do this directly,.

SQL MAX () on date value: Here we have discussed the usage of SQL MAX () function on date type of column of a table. SQL WHERE clause along with the SQL MAX () can be used as a subquery to find the maximum value of a column based upon some condition. For example, the following query returns the values of X and the percentage of the total for each row. Query on the other hand uses its CASE expression to evaluate the MAX () of the values in both coland col2. I am trying to generate a summary report using various aggregate functions: MIN, MAX , SUM, etc.

I am unable to get the MIN value of a field when I am using the case statement. This tutorial is designed for beginners who want to get started with PROC SQL. Also, it will attempt to compare the techniques of DATA Step and PROC SQL.

But it can be accomplished fairly straightforwardly with SAS proc sql as shown below.

Proc sql is first used to select distinct cities and to save them to a new dataset. It is used again to create all. In addition, Proc SQL always provides alternative ways to manage data, besides the traditional Data Step and procedures. SAS also supplies some goodies, such as its functions, to further strengthen SQL operation by Proc SQL.

Here are ten powerful functions for Proc SQL. The corresponding illustrations are given below for each function. Five reasons to use the DATA Step or PROC SQL. The DATA Step is a true workhorse. It allows you to create multiple datasets in one swift step.

PROC SQL requires several SELECT clauses to create multiple datasets. The ability of SAS to read virtually any data (text files, etc.) is outstanding. The CASE statement goes through conditions and returns a value when the first condition is met (like an IF-THEN-ELSE statement).

So, once a condition is true, it will stop reading and return the result. If no conditions are true, it returns the value in the ELSE clause. In case you are intereste the actual application of this technique (that is, why I needed it) in discussed in the article Annotate features of a schematic box plot in SGPLOT.

To goal of that article is to modify the output from PROC BOXPLOT in the case where the data set has no outliers or has only high outliers (or only low outliers). In this post, we explore the Case -Switch statement in SQL. Syntax: There can be two valid ways of going about the case -switch statements. The first takes a variable called case _value and matches it with some statement_list.

For example we have a table and three of its columns are of DATETIME type: UpdateByApp1Date, UpdateByApp2Date, UpdateByApp3Date. We want to retrieve data from the table and load it.
