+# The `SQLinDS` package, version: `2.4.0`;
+

+ 
+
+The **SQLinDS** package is an implementation of 
+the *macro-function-sandwich* concept introduced in the 
+*"Use the Full Power of SAS in Your Function-Style Macros"*,
+the article by *Mike Rhoads (Westat, Rockville)*.
+
+The article is available at:
+[https://support.sas.com/resources/papers/proceedings12/004-2012.pdf](https://support.sas.com/resources/papers/proceedings12/004-2012.pdf)
+
+Copy of the article can also be found in *additional content* directory.
+
+Package provides ability to *execute* SQL queries inside a data step, e.g.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  data class;
+    set %SQL(select name, age from sashelp.class);
+  run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+See the help for the `%SQL()` macro to find more examples. 
+
+### Content ###################################################################
+
+SQLinDS package contains the following components:
+
+1. `%SQL()` macro - the main package macro available for the User
+2. `dsSQL()` function (internal)
+3. `%dsSQL_inner()` macro (internal)
+4. Library `DSSQL` (created as a subdirectory of the `WORK` library)
+5. Optional KMF-abbreviations `sqlinds`

+## `dssql` libname <a name="dssql-libname-1"></a> ######
+ 
+The `dsSQL` library stores temporary views 
+generated during the `%SQL()` macro execution.
+
+If possible a sub-directory of the `WORK` location is created, like: 
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+LIBNAME dsSQL BASE "%sysfunc(pathname(WORK))/dsSQLtmp";
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+if not possible, then redirects to the `WORK` location, like:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+LIBNAME dsSQL BASE "%sysfunc(pathname(WORK))"; 
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+
+

+ 
+## `%dssql_inner()` macro <a name="dssqlinner-macro-2"></a> ######
+ 
+The `%dsSQL_Inner()` macro is an **internal** 
+macro called by `dsSQL()` function.
+
+The macro generates a uniquely named SQL view on the fly
+which is then stored in the `dsSQL` library.
+
+The `%dsSQL_Inner()` is *not* designed to be 
+called on its own. 
+ 
+Recommended for *SAS 9.3* and higher.

+ 
+## `%sql()` macro <a name="sql-macro-3"></a> ######
+ 
+The `%SQL()` macro is the **main** 
+macro in the package. The macro allows 
+to use SQL queries in the data step.
+ 
+Recommended for *SAS 9.3* and higher.
+ 
+Implementation is based on the article:
