SQL 服务器分割超过申报价值
SQL Server division over a declared value
我正在使用 SQL Server 2005，我想检查 "TypeHopper_0x" 值 if = 2，将 "CycleHopper_0x" 添加到 @nat_weight，这部分我是能够完成。现在@nat_weight = 1871。
现在我想除以 "cycleHopper_0x) by the @nat_weight and UPDATE the value to "HPR_x_PRCT" 的值，这就是我遇到问题的地方。我用这段代码定位索引 8000，但最终我需要运行 整个 table.
对于料斗 5，操作更新 E 177/1871 = 0.0149
