To override the predetermined
legacy SAS data type, you can specify the DBSASTYPE= option in order
to specify the data type to which to convert. Note that some data
types are not supported.
For example, in the
following code, DBSASTYPE= specifies a data type to use for the column
MYCOLUMN:
proc print data=mylib.mytable (dbsastype=(mycolumn=char(20)'));
run;
