php - 我尝试将其转换为与 Laravel 的 DB 类一起使用，但它没有返回任何内容

Question

我正在尝试将 Sql 查询转换为 Laravel 查询，但收到错误:？

SQLSTATE[HY000]: General error: 2809 General SQL Server error: Check messages from the SQL Server [2809] (severity 18) [(null)] (SQL: GetRegisteredUserData)

我的查询1:

SELECT * FROM  RegisteredUser WHERE DateCreated between '$startDate' AND  '$endDate' ORDER BY Yr DESC,MnthNo DESC

我的查询2:

SELECT * from  UserData where((Yr * 10000 + Mnth * 100 + 1) BETWEEN $startDate AND $endDate) ORDER BY Yr Asc, Mnth Asc

Answer 1

如果 $startDate 和 $endDate 是日期或日期时间。 此查询将对您有所帮助。

    SELECT * from  UserData where
    where cast(
    left(cast(yr*10000+mnth*100+day as varchar),4)+'-'+substring(cast(yr*10000+mnth*100+day as varchar),5,2)+'-'+right(cast(yr*10000+mnth*100+day as varchar),2)
    as datetime)
    between $startDate AND $endDate

我的建议是创建一个函数。

    create function fn_returndtae(@yr int,@mnth int,@day)
    returns datetime
    as
    return 
    (
    select
    cast(
            left(cast(@yr*10000+@mnth*100+@day as varchar),4)+'-'+substring(cast(@yr*10000+@mnth*100+@day as varchar),5,2)+'-'+right(cast(@yr*10000+@mnth*100+@day as varchar),2)
            as datetime)
    )

并在 WHERE 子句中使用。

    SELECT * from  UserData where
    where db_name.dbo.fn_returndtae(yr,mnth,day)
    between $startDate AND $endDate

谢谢
