CHAR(ROUND(RAND() * 9 + 48,0)) 写一个存储过程来应用上面这篇的SQL语句: up_RandomNumber CREATE PROCEDURE [dbo].[usp_RandomNumber] ( @Len INT = 1, --随机数位数 @Rows INT = 1 --随机笔数 ) AS BEGIN DECLARE @T AS TABLE([Random Number] VARCHAR(MAX)) DECLARE @L INT = 1, @R ...
Create random string using the function NEWID, this will give us a random 36 characters string. Clean the dash character, this will give us a random 32 characters string. Create a random number using the function NEWID, as the string length. Cut the string using the function LEFT...
SELECT RAND(@counter) Random_Number SET @counter = @counter + 1 END 2-3-2 行集函数 行集函数可以在Transact-SQL语句中当作表引用。下面的案例将通过行集函数OPENQUERY()执行一个分布式查询,以便从服务器local中提取表department中的记录。 select * from openquery(local, ‘select * from department’) 2...
) tORDERBYt.RandomID 关键在于调用了内置函数NEWID()生成的随机数,并排序,取前5行。 分页查询,需要查询Person.Address中按城市排序后的第50-200行,当然可以写一个存储过程来专门按参数来查询。 SELECT*FROM(SELECT*,ROW_NUMBER()OVER(ORDERBYCity)asRowNumberFROMPerson.Address )AStWHEREt.RowNumberBETWEEN50AND...

The script creates and loads table checkRank with relatively random data (see CreateCheckRank.sql in the Download file), but the stored procedure (see Listing 1) is more complex and uses a recursive algorithm, nested procedures calls, and nested subqueries to calculate the answer....
