This section provides a detailed
reference to each of the SQL commands likely to be used by the DBA.
Each command is listed in one or more of its forms, with the exact
syntax of the command and its associated parameters, a short
explanation of the purpose of the command, an example, and usage
notes where applicable.
Note
Many statements allow you to specify a schema name. For example, if
you specify:
CREATE TABLE schema.table_name
the table is created in the specified schema. If you simply specify:
CREATE TABLE table_name
the table is created in the schema of the user executing the command.
