1.基本方法是，编写函数fun：deletechar()。这个函数需要接受两个参数的传入，一个为该字符串str，另一个为想删除的字符c。通过对整个字符串的逐个遍历，凡是检测到字符为c，则删除此字符。具体实现代码如下：2.在主函数，只需要接受用户输入的字符串，然后调用deletechar()函数，最后输出结果即可。主函...

这里指的是char字符串变量,不是数组,此时使用: EXEC SQL for :delete_rows delete FROM table_name WHERE c= :c; 由于c只是一个变量字符串,此时delete_rows会失效,只会执行一次该语句,有多少条删除多少条记录。 总结: 1. 对于VARCHAR类型数组,Oracle会根据指定删除行数的整数,与array host数组变量的容量之间,...
