在 SQL 值中插入随机名称
Inserting Random Names in as SQL values
所以我创建了一个数据库，它是一个银行，里面有客户；但在该数据库中，我编写了一个函数 returns 50 个客户（或者在我的例子中，50 个 John Smiths）
...因为我在该代码中硬编码了我客户的姓名 John Smith 和他的电子邮件地址。现在我想找到一种方法来替换我用硬编码的名字和姓氏的变量，该变量将仅 return 随机名称。像 James Doe、Sally Fields 等...
请指出正确的方向，可以正确地用随机名称替换 John Smiths。
这是我的函数的代码，因此您可以了解我在说什么以及我在寻找什么。
BEGIN
DECLARE @loopCount tinyint
DECLARE @tableCount tinyint
DECLARE @randomSSN int
SELECT @loopCount = 1
WHILE (@loopCount <= 50)
BEGIN
SELECT @randomSSN = RAND()*(999999998)+1
SELECT @tableCount = COUNT(*) FROM Customer WHERE SSN = @randomSSN
IF @tableCount = 0
INSERT INTO Customer (FirstName, LastName, Email, SSN) VALUES ('John', 'Smith', 'JohnSmith@gmail.com', @randomSSN)
SELECT @loopCount = @loopCount +1
END
END
你可以使用这样的东西
