STUFF (<character_expression1>, <start_ position>, <length>,<character_expression2>) 如果起始位置为负或长度值为负,或者起始位置大于character_expression1 的长度,则返回NULL 值。如果length 长度大于character_expression1 中 start_ position 以右的长度,则character_expression1 只保留首字符。 7,CONCAT(s1,...
游标是SQL Server的一种数据访问机制,它允许用户访问单独的数据行。用户可以对每一行进行单独的处理,从而降低系统开销和潜在的阻隔情况,用户也可以使用这些数据生成的SQL代码并立即执行或输出。 1.游标的概念 游标是一种处理数据的方法,主要用于存储过程,触发器和 T_SQL脚本中,它们使结果集的内容可用于其...
