Sql 联接时筛选，但仍返回所有行

我不知道该怎么解释。我所能解释的最好的情况是，我想做一些类似于左联接的事情，只想返回与联接表的条件匹配的主表的子集，但仍然返回所有左联接行。我希望这有点道理

我有4张桌子：

公司

服务

服务贸易

公司服务

一个公司可以有很多服务，一个服务可以有很多翻译。 我想在ServiceTranslation表中筛选给定搜索词

我能让它工作的唯一方法是在下面的SQL中，但我觉得也许有更好更干净的方法来做这件事，或者我的解决方案可以吗

        DECLARE @defaultLanguage NVARCHAR(5)

        SET @defaultLanguage = (SELECT LanguageCode FROM LANGUAGE WHERE IsDefault = 1)

        SELECT
            c.Id,
            c.Name,
            c.OrgNr,
            c.UserId,
            c.Address,
            c.PostalArea,
            c.County,
            c.Country,
            c.Description,
            c.DescriptionFull,
            c.Telephone,
            c.Email,
            c.Website,
            c.IsApproved,
            s.Id,
            ISNULL(tr.Name, def.Name) Name

          FROM Company c

          INNER JOIN CompanyService cs on cs.CompanyId = C.Id

          INNER JOIN Service s on s.Id = cs.ServiceId 

          LEFT OUTER JOIN ServiceTranslation tr
            ON s.Id = tr.ServiceId AND tr.LanguageCode = @userLanguage
          -- join default language of the service:

          LEFT OUTER JOIN ServiceTranslation def
            ON s.Id = def.ServiceId AND def.LanguageCode = @defaultLanguage 

          WHERE c.IsApproved = 1 

          AND
          c.Id IN 
          (
              SELECT c1.Id FROM Company c1

              INNER JOIN CompanyService cs1 on cs1.CompanyId = c1.Id

              INNER JOIN Service s1 on s1.Id = cs1.ServiceId 

              INNER JOIN ServiceTranslation tr1
                ON s1.Id = tr1.ServiceId AND tr1.LanguageCode = @userLanguage
              -- join default language of the service:

              INNER JOIN ServiceTranslation def1
                ON s1.Id = def1.ServiceId AND def1.LanguageCode = @defaultLanguage



               AND s1.IsApproved = 1 AND  ISNULL(tr1.Name, def1.Name) LIKE '%' + @searchQuery + '%'
          )

提前谢谢

编辑：

我认为需要作出一些澄清。我不知道如何以可读的格式添加表数据，所以我附上了一些表的图像和所需的结果

公司表：

服务表：

服务翻译表：

公司服务表：

所需结果（@userLanguage='nb NO'和@searchquery='Transport'）：

有两家公司的服务中有“运输”一词。我要把这两家公司连同他们的其他服务一起退回

正如您从结果图像中所看到的，im过滤了拥有匹配服务但仍希望返回匹配公司及其所有服务的公司

我希望这能让事情更清楚一点：）

使用CTE：

;WITH Comps AS
(
    SELECT DISTINCT c.CompanyId FROM CompanyService  C 
    LEFT JOIN  ServiceTranslation tr ON tr.ServiceId = C.ServiceId AND tr.LanguageCode = @userLanguage AND tr.Name LIKE '%' + @searchQuery + '%'
    LEFT JOIN ServiceTranslation def ON def.ServiceId = C.ServiceId AND def.LanguageCode = @defaultLanguage AND def.Name LIKE '%' + @searchQuery + '%'
    WHERE tr.ServiceId IS NOT NULL OR def.ServiceId IS NOT NULL
)

    SELECT
        c.Id,
        c.Name,
        c.OrgNr,
        c.UserId,
        c.Address,

我认为样本数据和期望的结果会很有帮助。您想返回哪个子集？您在主SELECT语句=>`c.Website，c.IsApproved，s.Id，ISNULL（tr.Name，def.Name）Name`@J.D.中的s.Id后面缺少一个逗号。很抱歉，这是一个拼写错误，我现在已经修复了它，谢谢。我认为示例数据和所需的结果将非常有用。您要返回哪个子集？您在主SELECT语句=>`c.Website，c.IsApproved，s.Id，ISNULL（tr.Name，def.Name）Name`@J.D.中的s.Id后面缺少一个逗号。很抱歉，这是一个拼写错误，我现在已经修复了它，谢谢。我已经尝试过了，但这只返回与搜索参数匹配的公司和服务行。我添加了更多的细节来解释我想要什么。非常感谢你，我知道必须有更干净的方法！这很有见地！我已经试过了，但只返回与搜索参数匹配的公司和服务行。我添加了更多的细节来解释我想要什么。非常感谢你，我知道必须有更干净的方法！这很有见地！
