Macro and Proc SQL

iusing — Mon, 07 Nov 2011 12:09:32 GMT

I am trying to collect the data from the SQL server. Because, I would need to repeat it for many times, I have to write a macro like the following:

%macro _input (table=, input=);

PROC SQL;

CONNECT TO xxxx as xxxx (NOPROMPT= "DSN=xxxx;SERVER=xxxx;UID=;PWD=;

DATABASE=xxxx");

CREATE TABLE website.&table. AS

SELECT * FROM CONNECTION TO xxxx

(&input.);

QUIT;

%mend;

where xxxx is the connection information to the SQL server.

Table is just the table name and input would be sth. like

Select abc, sum(def) as ddd from abc where abc like '%bb%' group by abc

I put all the data into the table and try to run the macro but it fail.

I would like to know is it possible to put the whole SQL script as an input value of a macro.

One easier (I think) possibility would be to build a data _null_ datastep with two things: (1) a call execute statement to run your proc sql commands and inserting (2) the two variables (i.e., tablename and selectlist) that you would list in the datalines.

It would help if you posted your code and log.

%macro _input (table=, input=);

PROC SQL;

CONNECT TO xxxx as xxxx (NOPROMPT= "DSN=xxxx;SERVER=xxxx;UID=;PWD=;

CREATE TABLE website.&table. AS

SELECT * FROM CONNECTION TO xxxx

(&input.);

QUIT;

%mend;

Input_Table:

Table Input

bb Select abc, sum(def) as ddd from abc where abc like '%bb%' group by abc

dd Select abc, sum(def) as ddd from abc where abc like '%dd%' group by abc

data _null_ ;

set input_table;

call execute ('%_input (table='||Table||',input='||Input||')');

run;

I was suggesting something more like:

data _null_;

informat selections $100.;

input table $ selections &;

call execute('PROC SQL;

CREATE TABLE '||table||' AS '||

selections||'; QUIT;');

cards;

aa select name, sum(height) as ddd from sashelp.class where name like '%A%' group by name

jj select name, sum(height) as ddd from sashelp.class where name like '%J%' group by name

;

Maybe should like:

Input_Table:

Table Input

bb %nrstr(Select abc, sum(def) as ddd from abc where abc like '%bb%' group by abc)

dd %nrstr( Select abc, sum(def) as ddd from abc where abc like '%dd%' group by abc)

put only the create table statement in the macro

Make and break the connection outside the macro, like:

%macro _input (table=, input=);

CREATE TABLE website.&table. AS SELECT * FROM CONNECTION TO xxxx (&input.);

%mend;

PROC SQL;

CONNECT TO xxxx as xxxx (NOPROMPT= "DSN=xxxx;SERVER=xxxx;UID=;PWD=; DATABASE=xxxx");

%input( table= xxxxxxxxxxxxxx, input= yyyyyyyyyyyyyyyyyyyyy );

disconnect from xxxx ;

QUIT;
