Check if ODBC connection is created or not

Hello, 

 

I created ODBC connection from Startthen selectControl Panel then selectSystem and Securitythen selectAdministrative Toolsthen selectData Sources (ODBC).

In SAS code i created the connection as follow: 

proc sql;

connect to odbc as mydb (dsn=&dsn);

execute
(set nocount on) by mydb;

 

i need to check if mydb object is actually connected to DB or not. so please help me to implement this in SAS 

 

i think it will be like that: 

if not mydb then  -- if the connection isn't created, then create the connection

    proc sql;

    connect to odbc as mydb (dsn=&dsn);

    execute
    (set nocount on) by mydb;

endif

Re: Check if ODBC connection is created or not

An ODBC connection in SAS SQL only lasts as long as the SQL step boundary (the QUIT statement or another DATA or PROC statement) then it is automatically disconnected. Why do you want to check your connection? If it doesn't work then you get appropriate messages in your SAS log. 

 

proc sql
  connect to ODBC as mydb (....); <== creates connection

  SQL statements

quit; <== removes connection

Re: Check if ODBC connection is created or not

You should be able to assign a library to the odbc connection and then use any of the SAS tools for examining the contents of the library.

 

Something like:

libname test odbc noprompt="dsn=&dsn";

 

If the library gets assigned you should see data there.

Check function libname() or libref()  .

 

%if (%sysfunc(libref(sashelp))) %then %put ERROR ;
