CREATE SYNONYM statement allows you to create an alternate name
for a table or a view.
An SQLIdentifier, which can optionally include a schema name. This is the new name you want to create for the view or table.
An SQLIdentifier that identifies the view for which you are creating a synonym.
An SQLIdentifier that identifies the table for which you are creating a synonym.
Currently, you can only use a synonym instead of the original qualified
table or view name in these statements:
Here are a few other important notes about using synonyms:
- Synonyms share the same name space 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.
- You can create a synonym for a table or view that does not yet exist; however, you can only use the synonym if the table or view is present in your database.
- You can create synonyms for other synonyms (nested synonyms); however, an error will occur if you attempt to create a synonym that results in a circular reference.
- You cannot create synonyms in system schemas. Any schema that starts
SYSis a system schema.
- You cannot define a synonym for a temporary table.
