Options for the ACCESS Procedure

Depending on which options you use, the PROC ACCESS statement performs several tasks.
You use the PROC ACCESS statement with database-description statements and certain procedure statements to create descriptors or SAS data files from DBMS data. See Invoking the ACCESS Procedure for information about which procedure statements to use for each task.
specifies an access descriptor.
ACCDESC= is used with the DBMS= option to create a view descriptor that is based on the specified access descriptor. You specify the view descriptor's name in the CREATE statement. You can also use a SAS data set option on the ACCDESC= option to specify any passwords that have been assigned to the access descriptor.
The ACCDESC= option has two aliases: AD= and ACCESS=.
specifies which database management system you want to use. DBMS= can be used with the ACCDESC= option to create a view descriptor, which is then named in the CREATE statement.
specifies the SAS data file to which DBMS data are written. OUT= is used only with the VIEWDESC= option.
specifies a view-descriptor that accesses the ADABAS data. VIEWDESC= is used only with the OUT= option. For example:
proc access dbms=adabas viewdesc=vlib.invq4 out=dlib.invq4;
The VIEWDESC= option has two aliases: VD= and VIEW=.
Altering a DBMS table can invalidate descriptors.
Altering the format of a DBMS table that has descriptor files defined on it might cause these descriptors to be out-of-date or no longer valid. For example, if you add a column to a table and an existing access descriptor is defined on that table, the access descriptor and any view descriptors that are based on it do not show the new column. You must re-create the descriptors to be able to show and select the new column.
