Question

我有一个帮助程序，它通过将... axios.post('http://localhost:5000/users/register', body , config ) .then(res => dispatch({ type : ActionType.REGISTER_SUCCESS, payload : res.data })) ...替换为文字参数来返回分页的SQL查询：

{}

因此最终的SQL可能如下所示：

WITH CTE AS
(
    SELECT {InnerFields}, ROW_NUMBER() OVER (ORDER BY {OrderBy}) AS _RowNumber_
    FROM {SourceTable}
    WHERE {Filter}
)
SELECT {OuterFields}, (SELECT COUNT(*) FROM CTE) AS ID
FROM CTE
WHERE _RowNumber_ BETWEEN {From} AND {To}

然后将查询传递给Dapper，并包装其参数 WITH CTE AS ( SELECT OrderId, Date, Amount, ROW_NUMBER() OVER (ORDER BY OrderId) AS _RowNumber_ FROM Orders WHERE VID=@VID AND Date BETWEEN @From AND @To ) SELECT OrderId, Date, Amount, (SELECT COUNT(*) FROM CTE) AS ID FROM CTE WHERE _RowNumber_ BETWEEN 1 AND 20：

Dictionary<string, object>

这在本地和生产服务器上都可以正常工作。但是在生产中，当数据窗口是new Dictionary<string, object> { ["VID"] = 123, ["From"] = "2019-01-01T00:00:00", ["To"] = "2019-07-01T00:00:00" }而不是_RowNumber_ BETWEEN 101 AND 120或121 AND 140时，我遇到了一个奇怪的错误101 AND 110。谁能指出我为什么对范围如此挑剔？

更新：

SQL Server Profiler指示成功的查询会触发包含Must declare the scalar variable "@VID"和所有参数的RPC:Completed事件，而错误的查询会导致sp_executesql和SQL:BatchStarting事件，而没有参数。除了范围值，查询本身是相同的。

返回错误“必须声明标量变量”
