Exporting SAS dataset to MS Access: Specify Numeric Field Size as Long Integer Instead of Double

[jcis7]

G'day.

Appreciate any help you can give.

I realized it saves space in MS Access if a numeric field has a length of 'Long Integer' instead of 'Double'.

When I use the following code, SAS exports numeric fields into MS Access as 'Double' instead of 'Long Integer'.  Is it possible to ask SAS to specify the field size as 'Long Integer' instead of 'Double'?  Thanks!

PROC EXPORT DATA= WORK.want
OUTTABLE= "Want" 
DBMS=ACCESS REPLACE;
DATABASE="W:\Databases\&database"; 
RUN;

This link documents the default data type conversions:

Given Long Integer is not listed you would need to use the DBTYPE dataset option to specify such a conversion:

Appreciate your help! For the example I copied and pasted from one link you included, I've a few questions:

1) If I wanted the type to be long integer, do I use LONGINT instead of SMALLINT?

2) What does the '9(5)' mean?

Thank you!



Example 3: Specify a Data Type for a Column in a New Table
This example creates a new Teradata table, NEWEMPLOYEES, and specifies a data type and attributes for the EMPNO column. The example encloses the Teradata type and attribute information in double quotation marks. Single quotation marks conflict with single quotation marks that the Teradata FORMAT attribute requires. If you use single quotation marks, SAS returns syntax error messages.
data mydblib.newemployees(dbtype= (empno="SMALLINT FORMAT '9(5)'
CHECK (empno >= 100 AND empno <= 2000)"));
set mydblib.employees;
run;

I suggest you give it a try with LONGINT and see how you get on. 9(5) means a decimal with 5 decimal places and a total length of 9 digits.

Thank you! One last question:  Is there anyway to change it in an existing table?

This isn't really a SAS question. I suggest you Google Microsoft Access modify table column type.
