原文地址:在PLSQL中编译复杂的java PLSQL中可以编译运行JAVA程序. 一个简单的例子: create or replace and compile java source named xxfnd as package xxfnd;public class Test{ public void Test(){ } public static String helloWorld{ return "success"; }} 但是如果真的想在PLSQ
nvarchar(max)长度测试:在使用convert强制类型转化之后 文本长度可以突破8000的上限.并且nvarchar(max)的最大长度可达到2^31以下为验证SQL: Declare @A nvarchar(max) set @A=replicate('*',9000); print len(@A) set @A=replicate(CONVERT(nvarchar(max),'*'),9000); print len(@A) set @A=replicate(CONVERT(nva
Write a program to print a histogram of the lengths of words in its input. It is easy to draw the histogram with the bars horizontal; a vertical orientation is more challenging. 统计输入中单词的长度,并且绘制相应的直方图.水平的直方图比较容易绘制,垂直的直方图较困难一些. /* This program was the
HTTP中的URL长度限制 首先,其实http 1.1 协议中对url的长度是不受限制的,协议原文: The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length
1)如果不指定number的长度,或指定长度n>18 id number not null,转换为pojo类时,为java.math.BigDecimal类型 2)如果number的长度在10 <= n <= 18 id number(n) not null,转换为pojo类时,为java.lang.Long类型 3)如果number的长度在1 <= n <= 9 id number(n) not null,转换为pojo类时,为java.lang.Integer类型
