3. 编写Oracle存储过程,包含 TRUNCATE TABLE 操作 以下是一个示例存储过程,它使用 EXECUTE IMMEDIATE 来执行 TRUNCATE TABLE 操作: sql CREATE OR REPLACE PROCEDURE truncate_table_proc (p_table_name IN VARCHAR2) IS BEGIN EXECUTE IMMEDIATE 'TRUNCATE TABLE ' || p_table_name; END truncate_table_proc; /...
可以使用用户u1创建存储过程, create procedure u1.stgtruncate(table_name in varchar2) as begin execute immediate 'truncate table '||table_name; end; 然后将该存储过程的权限赋予u2, grant execute on u1.stgtruncate to u2; 现在登录u2,通过执行如下sql即可truncate u1下的表test1a call u1.stgtruncate('...

-- oracle中truncate其他用户的表必须要有drop any table权限,如果没有此权限,可以采用下面的方法 -- 1.创建存储过程 create or replace procedure truncate_tbl (table_name in varchar2)authid definer as cursor_id integer;begin cursor_id := dbms_sql.open_cursor;dbms_sql.parse(cursor_id,...

TRUNCATETABLEstudent RESTARTIDENTITY; As you can see, the TRUNCATE TABLE statement is pretty simple to use. In most cases, you can just run the “TRUNCATE TABLE tablename” command. Truncate Table in a Stored Procedure Are you trying to run a TRUNCATE TABLE statement inside astored procedure?
Truncate语句是Oracle SQL体系中非常有特色的一个。Truncate直接的效果是进行数据表数据的清理,深层次是一种典型的DDL语句。 Truncate语句是Oracle SQL体系中非常有特色的一个。Truncate直接的效果是进行数据表数据的清理,深层次是一种典型的DDL语句。Oracle中,delete语句是一种标注动作。在执行过程中,数据...
当MySQL 5.7 使用规范配置启动时,从debug-trace过程来看,在row_drop_single_table_tablespace、row_drop_table_from_cache函数执行期间根本没有耗时,所以实施优化方案后,没有效果; 耗时的过程在que_eval_sql: query: PROCEDURE DROP_TABLE_PROC ---> dict_drop_index_tree; ...
If you would change something in the package body (a line of code, not simply a comment), you will find that LAST_DDL_TIME changes. LAST_DDL_TIME changes for CREATE OR REPLACE ... 1. When the source of the procedure changes.
