Proc SQL Log Messages

slolay — Fri, 13 Jan 2012 13:55:36 GMT

Hi All

Just started to use Proc SQL.

Is it possible to get more informative messages in the log when running proc SQL code. It only seems to give the number of obs in the final output dataset but I would also like to see values for the input tables esp. when using joins and where clauses when reading the datasets in....still a DATA STEP man!

Regards
Steve

There is the undocumented _METHOD option on the PROC SQL statement but that only describes the joins used not the number of input rows. I suspect it may not be possible....

You should check the documentation , there is lots of option to produce some more information at log.

e.g option feedback can let you know what SQL code generated by SAS.

Thanks for the replies.

Had a look at the SAS documetation: http://support.sas.com/documentation/cdl/en/sqlproc/62086/HTML/default/viewer.htm#a001360938.htm

but nothing there about getting information about how many input records were read in. I hope SASkiwi is not right and it is not possible..it would be useful to have this information in the log.

Hi.

Sorry. I also do not know there is an option can report such information.

Maybe you can talk with Technical Support.

I suspect that there is not such an option. PROC SQL does not necessarily even read all the rows, nor would the underlying data base engine. You could use the DESCRIBE statement to get some information about the underlying tables.

Thanks for all your help guys

I think SAS users could really benefit from log info regarding how many obs where read in for each input table as often where clauses are attached to them when reading in them in

Have a good day

If you do a Create View in SQL, and have a data step or other PROC reading that view, it will display no of input rows in the log.

Not very neat...
