Setting Code Attribute UNICODE
To be able to store the application data [Page 125] in UNICODE [Page 152], the database
must be UNICODE-enabled and you must set the code attribute [See SAP DB Library]
UNICODE for the required application data (Installing a UNICODE-Enabled Database [Page
91]). You can set the code attribute in the following ways:
• Database parameter DEFAULT_CODE [Page
81] is not set to value UNICODE.
In the column definition, make sure you enter code attribute UNICODE. Application data
is then only stored in UNICODE for these column values.
If you do not enter a code attribute, the code entered in the parameter DEFAULT_CODE
(that is to say, not UNICODE) is used for these column values.
• Database parameter DEFAULT_CODE is set to value UNICODE.
In the column definition, enter code attribute UNICODE. Application data is stored in
UNICODE for these column values.
If you do not enter a code attribute, the application data is stored in UNICODE for these
column values, because the parameter DEFAULT_CODE is set to UNICODE.
Database parameter DEFAULT_CODE is set to value UNICODE.
