c# - C# sql if 查询

Question

我试着做

var sql = String.Format("if ( {0} > (select sStrength from yCell where Cell_ID = '{1}')) begin UPDATE yCell SET sStrength = {0} WHERE Cell_ID = '{1}' end", inMaxStrength, inCellID);
                   SqlCeCommand myCommand = new SqlCeCommand(sql,connection);
                    myCommand.ExecuteNonQuery();

有一个错误：令牌行号= 1，令牌行偏移量= 1，错误中的令牌= if 但是在sql studio中它运行正常。

不能说为什么会失败，但我可以建议您尝试在一个命令中更新：

UPDATE yCell SET sStrength = {0} WHERE Cell_ID = '{1}' AND {0} > sStrength
