where is SQLDATA?

given the following scenario, how do I extract the values from SQLDATA?

exec sql
prepare s1_select from :g_sqlstmt;

exec sql
declare c1 scroll cursor for s1_select;

exec sql open c1;

exec sql fetch first from c1;


My attempt is...


exec sql include sqlda;
exec sql describe s1_select into :sqlda;

for i = 1 to sql_num;

sqlvar = sql_var(i);
if sqlname = ' ';
leave;
endif;

SQLDATA???? contains null when the fetch did indeed fetch a record.
