SAS/ACCESS Interface to Sybase IQ

Naming Conventions for Sybase IQ

For general information about this feature, see SAS Names and Support for DBMS Names.

Since SAS 7, most SAS names can be up to 32 characters long. SAS/ACCESS Interface to Sybase IQ supports table names and column names that contain up to 32 characters. If DBMS column names are longer than 32 characters, they are truncated to 32 characters. If truncating a column name would result in identical names, SAS generates a unique name by replacing the last character with a number. DBMS table names must be 32 characters or less because SAS does not truncate a longer name. If you already have a table name that is greater than 32 characters, it is recommended that you create a table view. For more information, see SAS Names and Support for DBMS Names.

The PRESERVE_COL_NAMES= and PRESERVE_TAB_NAMES= options determine how SAS/ACCESS Interface to Sybase IQ handles case sensitivity. (For information about these options, see Overview of the LIBNAME Statement for Relational Databases.) Sybase IQ is not case sensitive, so all names default to lowercase.

Sybase IQ objects include tables, views, and columns. They follow these naming conventions.

A name must be from 1 to 128 characters long.
A name must begin with a letter (A through Z), underscore (_), at sign (@), dollar sign ($), or pound sign (#).
Names are not case sensitive. For example, CUSTOMER and Customer are the same, but object names are converted to lowercase when they are stored in the Sybase IQ database. However, if you enclose a name in quotation marks, it is case sensitive.
A name cannot be a Sybase IQ reserved word, such as WHERE or VIEW.
A name cannot be the same as another Sybase IQ object that has the same type.

For more information, see your Sybase IQ Reference Manual.
