When i run the same SQL (same SQL_ID) with the same binding in SQL Developer, SQL Plus or Quest SQL Optimizer (tried 8.x and 9.x) i have the result in 0.1 - 0.3 seconds.The SQL retrieve 1-300 rows, and also an another bind variable has no effect....
首先,分析 OracleHelper 类是否正确的添加了参数,参数名、类型、值等是否正确;问题依旧。 其次,测试 SQL 语句是否正确,并在 PL/SQL Developer 中使用 bind variable 的方法确认参数绑定是否正确;问题依旧。 最后,建立新的 WinForm 应用程序,使用 System.Data.OracleClient 命名空间提供的类,重新写段测试代码;终于查询...
What happens if you do use a bind variable (:var) in SQL*Plus? This is what PL/SQL Developer does. Marco Kalter Allround Automations Re: ora-01480: trailing null missing from STR bind value #1388504/07/0410:56 PM OP johnsok

今天用PL/SQL Developer往一个字段(VARCHAR(3000))里更新值时出错,报“ORA-01480: STR 赋值变量缺少空后缀”,查了一下英文定义为: ORA-01480: trailing null missing from STR bind value A bind variable of type 5 (null-terminated string) does not contain the terminating null in its buffer. ...
Fortunately Dave had just attended an IOUG conference. One of the presenters had demonstrated how queries that didn't use bind variable are vulnerable to SQL injection. This enables hackers to run arbitrary SQL statements and gain access to information that they should not be able to see. His...
b corresponding variable is a blob and will be sent in packets 二进制包 原理说明:为什么bind_param()可以防止SQL注入? 使用了占位符(“?”):无论传多少值都是安全的,因为她已经被定义成一个参数,而非一条语句的部分; 预编译模式:在数据库层已经被编译成特定的执行方式,如select、insert等,不会因为后续...
