This includes character and numeric values. Otherwise, with the normal conditions, you can still save values in a single variable. You can use conditions to filter the variable values using a where statement if you'd like to do so. Select variable_name into: macro_variable_name separated by ',' Macros and SQL are a strong combination, and using them together can go a long way.įor example, if you have a list of values you'd like to store in a macro variable, you can use the Proc SQL statement to create a macro variable. Having said this, it's imperative to be able to store values in an SQL variable for further use. SQL is one of the most commonly used languages within SAS for data manipulation and data processing. ![]() Related: Cool Microsoft Excel Macros for Sorting Data 3. Microchip Technology is a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions that also offers outstanding technical support. Open this document in SAS Help Center and click on the version in the banner to see all available versions. ![]() out_ds: name of the resulting dataset, which will be created after the dataset is sorted SAS® Macro Language: Reference 2020.1 - 2023.09 This document might apply to additional versions of the software.It starts with a MACRO statement and ends. sort_var: variable to use while sorting the dataset Macro is a group of SAS statements that is referred by a name and to use it in program anywhere, using that name.Function macros tend to emulate SAS numeric or string functions. %sorting: macro variable name created in the macro statement SAS macros tend to fall in one of two general groups: function macros and statement macros.To call the macro, pass the macro statement in the following manner: %sorting (in_ds= test_example, sort_var = name, out_ds=test_example_new) In the %macro statement, you can define the name of the macro, along with the local variables, which would hold certain values when the macro is called.įinally, end the macro code block with the %mend statement. Once the data is available, you can create a macro statement within the %macro and %mend statements. In the first block of code, create a dataset with some dummy values. Proc sort data = &in_ds nodupkey out = &out_ds %macro sorting (in_ds=, sort_var =, out_ds=) The whole block of statements can be reused to perform various functions, as and when needed.įor example, suppose you want to sort an existing dataset based on certain criteria. ![]() create custom windows and menus that interactively gather and validate user-supplied parameter values.Macro parameters are rather helpful when you want to define the variables and steps within a set of macro statements directly.create a macro function that validates whether a selected variable exists in a selected data set and returns the variable's type. ![]() create macro functions that return the number of observations in a data set or a subset of a data set.exploit SAS I/O and external file functions.Syntactically speaking, while SAS programming loops or do-loops always reside within SAS data step, SAS macro loops or do-loops are located within SAS macros. search for all SAS programs in a directory and all subdirectories and automatically submit every program That makes SAS macro loops a powerful code generator tool allowing to produce multiple variations of SAS code snippets with actually writing them just once.search for all CSV, Excel, or Microsoft Access files in a directory and all subdirectories and automatically import each file, worksheet, or table into a SAS data set.automatically convert data set variables to macro variables.apply SAS or user-defined formats to macro variables.exploit stored compiled and autocall macro facilities.set in&name.temp After macro variable resolution, SAS sees this statement: SET INSALES.TEMP You can end any macro variable reference with a delimiter, but the delimiter is necessary only if the characters that follow can be part of a SAS name. create hierarchical, menu-driven macro applications The first is the delimiter for the macro reference, and the second is part of the text.
