Sas Sql Macro Example
This provides a synopsis and edits of PROC SQL by Example, a book you can purchase online from SAS Books. The Essential PROC SQL Handbook for SAS Users and PROC SQL: Beyond the Basics Using SAS, Second Edition are also available for more assistance. Is it possible to use a macro variable for proc sql like condition? Sign so that SAS doesn't think you want to call macro. Using macro variable for proc sql. SAS does read the code inside the macro and it finds errors. Your statements inside the macro are not SQL statements and so they don't work inside of SQL.

How to use macros in SQL? (for every thing, that was selected)
I mean something like this:
The INTO clause for the SELECT statement can assign the result of a calculation or the value of a data column (variable) to a macro variable. If the macro variable does not exist, INTO creates it. You can check the PROC SQL macro variable SQLOBS to see the number of rows (observations) produced. When you specify a range of macro variables, the SAS Macro Facility creates only the number of macro variables that are needed. For example, if you specify:var1-:var9999 and only 55 variables are needed, only:var1-:var55 is created. The SQLOBS automatic variable is useful if a subsequent part of your program needs to know how many variables.
&VarTable is a table, which have two variables: (for example) Lib and Table
Each observation in &VarTable is the name of table: Lib.Table
I want to do things for every table:
1) exist?
2) sort it
and last condition: each table, if it exist, have a variable &VarField.
how to do this with sql and macros?

Do you have to use sql and macros? A simple data step and call execute would do what you need here. My free mp3.
Below is an example that takes a data set that has a list of tables to process, checks to see if the table exists and if it does, sorts it by &VarField. This could be easily extended to sort each table by a custom set of variables if desired.
If the table does not exist, it generates a warning message.

Call execute is a good solution, however if the data step code being 'executed' is complicated (which it is not in this example), I find it hard to debug. Igi 3 free download for windows 10.
Another method is to put all the variables into macro variables and then loop through them in a macro do-loop;
