If a query or DML statement affects four or more database rows, then bulk SQL can significantly improve performance. Note: You cannot perform bulk SQL on remote tables. PL/SQL binding operations fall into these categories: Binding CategoryWhen This Binding Occurs In-bind When an INSERT, ...
This section provides an overview of bulk binds to help you decide whether to use them in your PL/SQL applications. For detailed information about using bulk binds, including ways to handle exceptions that occur in the middle of a bulk bind operation, see Oracle Database PL/SQL Langua...

批量添加的方法是生成一条SQL语句,和数据库只交互一次。那为什么图片中有多条Insert语句呢,当你使用BulkInsert时,如果数据达到4万之前,那在SQL的解释时,也是很有压力的,有多情况下会超时,当然这与你的数据库服务器有关,但为了性能与安全,将Bulk操作变为分批提交,即将上W的数据进行分解,分用1W数据量提交一次,这样...
BULK COLLECT子句在Oracle数据库中如何使用? BULK COLLECT子句能提高查询性能吗? 如何在PL/SQL中使用BULK COLLECT子句? BULK COLLECT 子句会批量检索结果,即一次性将结果集绑定到一个集合变量中,并从SQL引擎发送到PL/SQL引擎。通常可以在SELECT INTO、 FETCH INTO以及RETURNING INTO子句中使用BULK COLLECT。本文将逐一描...
