INSERT语句用于向表中插入数据,而在PL/SQL中,可以将INSERT语句与其他语句结合使用,创建一个过程来实现特定的功能。 下面是一个示例,展示了如何在Oracle PL/SQL中使用INSERT语句创建过程: 代码语言:txt 复制 CREATE OR REPLACE PROCEDURE insert_data ( p_id IN NUMBER, p_name IN VARCHAR2, p_age IN NUM...
PL/SQL procedure successfully completed. Elapsed: 00:01:27.69 此时共用时1分27秒,大约是逐行提交方法一半的时间。由此可见,对于Oracle应该尽量以批量提交的方式来完成工作。 3、最后我们使用Oracle更高级的方法完成上面的任务,体验一下极限速度。 sec@ora10g> DECLARE 2 CURSOR cur IS 3 SELECT * FROM t_ref;...
最后,oracle数据库insert后获取insert数据的自增id值:(ADO.net中,可以直接调用该存储过程) createorreplaceprocedureusp_querysequence ( insrt_sqlinvarchar2, SEQ_NAMEinvarchar2,newidoutnumber)isstr_sqlvarchar(100);beginexecuteimmediate insrt_sql; str_sql :='select'||SEQ_NAME||'.CURRVAL from dual';exe...
PL/SQL_block | CALL procedure_name; 其中: INSTEAD OF 选项使ORACLE激活触发器,而不执行触发事件。只能对视图和对象视图建立INSTEAD OF触发器,而不能对表、模式和数据库建立INSTEAD OF 触发器。 FOR EACH ROW选项说明触发器为行触发器。行触发器和语句触发器的区别表现在:行触发器要求当一个DML语句操走影响数据...

bypassing the buffer cache. Free space in the existing data is not reused. This alternative enhances performance during insert operations and is similar to the functionality of the Oracle direct-path loader utility, SQL*Loader. When you insert into a table that has been created in parallel mode...

may i know what is the syntax for the stored procedure if i want create table and insert into statements at the same time. CREATE TABLE `db_license`.`aa` ( `key` VARCHAR(45) NOT NULL, `dfds` VARCHAR(45) NOT NULL, `sfsda` VARCHAR(45) NOT NULL ) insert into aa (day...
