+<section><p>Use the CREATE SYNONYM statement to provide an alternate name
+for a table or a view that is present in the same schema or another schema.
+You can also create synonyms for other synonyms, resulting in nested synonyms.
+A synonym can be used instead of the original qualified table or view name
+in SELECT, INSERT, UPDATE, DELETE or LOCK TABLE statements. You can create
+a synonym for a table or a view that doesn't exist, but the target table or
+view must be present before the synonym can be used.</p><p>Synonyms share
+the same namespace as tables or views. You cannot create a synonym with the
+same name as a table that already exists in the same schema. Similarly, you
+cannot create a table or view with a name that matches a synonym already present.</p><p>A
+synonym can be defined for a table/view that does not exist when you create
+the synonym. If the table or view doesn't exist, you will receive a warning
+message (SQLSTATE  01522). The referenced object must be present when you
+use a synonym in a DML statement.</p><p>You can create a nested synonym (a
+synonym for another synonym), but any attempt to create a synonym that results
+in a circular reference will return an error message (SQLSTATE 42916).</p><p>Synonyms
cannot be defined in system schemas. All schemas starting with 'SYS' are considered system
schemas and are reserved by <ph conref="refconrefs.dita#prod/productshortname"></ph>.</p><p>A
synonym cannot
+be defined on a temporary table. Attempting to define a synonym on a temporary
+table will return an error message (SQLSTATE XCL51).</p></section>
