EXAMPLE #1

5

Header = Yes / No• If the worksheet does not have a header row with variable names, header=no

has SAS apply the default variable names F1, F2, F3

Dbsaslabel = Compat / None• causes names from Excel column headers to be assigned as SAS variable labels.

SAS variable names are automatically converted from the column headers into SAS name rule compliant names.

Scan_time = Yes / No• specifies whether to scan all row values for a DATETIME data type field to

determine the TIME data type based on the setting.

Stringdates = Yes / No• specifies whether datetime values are read from the data source as character

strings or as numeric date values

Datetime = Yes / No• specifies whether to assign the DATE. or DATETIME. format for datetime

columns in the data source

COMMON LIBNAME OPTIONS

6

Mixed = Yes / No

• No: scans first 8 records (default) and makes best guess whether to designate a column as numeric or character

• Yes: convert such mixed columns to character, thus preserving character entries occurring deep in the data

• Problem: 8 records does not cut the mustard!!!!

• Solution: change a key on the computer’s registry

COMMON LIBNAME OPTIONS (CONT.)

• In the registry tree, select HKEY_LOCAL_MACHINE ► Software ►Wow6432Node ►Microsoft ► Office ► 14.0 ► Access Connectivity Engine ► Engines.

• Double-click the Excel node.

• In the right panel, double-click the TypeGuessRows entry.

• Change the value data from 8 to 0.

• Click OK.

• Select File ► Exit to exit the Registry Editor window.
