Name Resolution
Most database objects (tables, views, etc.) can be addressed using a qualified name, by prefixing the name of the object with the name of its containing schema, separated by a dot; e.g.:
|
|
For the full list of schema-contained objects, see CREATE SCHEMA.
If these objects are referenced without a schema, they will be looked for in the user's default schema, if one has been assigned.
The default schema can be overridden within an ODBC/JDBC session by issuing the SET CURRENT SCHEMA command. Once set, the new schema will be used to resolve unqualified names instead of the default schema--the user's default schema will be ignored for the purposes of name resolution.
Naming Criteria
Each database object is identified by a name, which will have the following SQL validation applied:
- Between 1 and 200 characters long
- First character is alphabetic, _, or #; if the object name is double-quoted, it can start with a number
- Each subsequent character must be alphanumeric, _, or #; if the object name is double-quoted, the following symbols, including spaces, can be used: { } [ ] ( ) : -
- Unique within its containing schema--cannot have the same name as another object of the same type in the same schema (two credentials can't have the same name in the same schema); tables & views are of the same "type" for this rule (a table can't have the same name as a view in the same schema)
Column names must meet the following criteria:
- Between 1 and 200 characters long
- First character is alphabetic or _; if the object name is double-quoted, it can start with a number
- Alphanumeric, including this symbol: _; if the object name is double-quoted, the following symbols can be used: { } [ ] : .
Note
Names that begin with a digit or contain a special character may need to be double-quoted when referenced. For example:
