请使用 create schema CREATE SCHEMA Purpose Use the CREATE SCHEMA to create multiple tables and views and perform multiple grants in a single transaction. To execute a CREATE SCHEMA statement, Oracle executes each included statement. If all statements execute successfully, Oracle commits the transaction. If any statement results in an error, Oracle rolls back all the statements. --------------------------------------------------------------------------------Note: This statement does not actually create a schema. Oracle automatically creates a schema when you create a user (see CREATE USER). This statement lets you populate your schema with tables and views and grant privileges on those objects without having to issue multiple SQL statements in multiple transactions. --------------------------------------------------------------------------------
Prerequisites The CREATE SCHEMA statement can include CREATE TABLE, CREATE VIEW, and GRANT statements. To issue a CREATE SCHEMA statement, you must have the privileges necessary to issue the included statements. Syntax Keyword and Parameters schema Specify the name of the schema. The schema name must be the same as your Oracle username. create_table_statement Specify a CREATE TABLE statement to be issued as part of this CREATE SCHEMA statement. Do not end this statement with a semicolon (or other terminator character). See Also: CREATE TABLE
create_view_statement Specify a CREATE VIEW statement to be issued as part of this CREATE SCHEMA statement. Do not end this statement with a semicolon (or other terminator character). See Also: CREATE VIEW
grant_statement Specify a GRANT object_privileges statement to be issued as part of this CREATE SCHEMA statement. Do not end this statement with a semicolon (or other terminator character). See Also: GRANT
The CREATE SCHEMA statement supports the syntax of these statements only as defined by standard SQL, rather than the complete syntax supported by Oracle. The order in which you list the CREATE TABLE, CREATE VIEW, and GRANT statements is unimportant. The statements within a CREATE SCHEMA statement can reference existing objects or objects you create in other statements within the same CREATE SCHEMA statement. Restriction: The syntax of the parallel_clause is allowed for a CREATE TABLE statement in CREATE SCHEMA, but parallelism is not used when creating the objects. See Also: the parallel_clause of CREATE TABLE
Example CREATE SCHEMA Example The following statement creates a schema named blair for the user Blair, creates the table sox, creates the view red_sox, and grants SELECT privilege on the red_sox view to the user waites. CREATE SCHEMA AUTHORIZATION blair CREATE TABLE sox (color VARCHAR2(10) PRIMARY KEY, quantity NUMBER) CREATE VIEW red_sox AS SELECT color, quantity FROM sox WHERE color = 'RED' GRANT select ON red_sox TO waites;
要不開始設置自動提交為OFF
即為sql>set autocommit off關閉自動提交功能,或為on ,immediate打開。
因为执行的时候就是从sql脚本中读取执行的。
感觉编程去自动drop创建过的对象,思路不怎么清晰,谁给点意见?
