There are two naming conventions that can be used in DB2® UDB for iSeries™ programming: system (*SYS) and SQL (*SQL).
The naming convention used affects the method for qualifying file and table names and the terms used on the interactive SQL displays. The naming convention used is selected by a parameter on the SQL commands or, for REXX, selected through the SET OPTION statement. See Qualification of unqualified object names in the SQL Reference for more details.
In the system naming convention, tables and other SQL objects in an SQL statement are qualified by schema name in the form:
schema/table
In the SQL naming convention, tables and other SQL objects in an SQL statement are qualified by the schema name in the form:
schema.table
