SQL 在查询中哪里使用 LIMIT

Question

我试图将我的结果限制为 10。下面的查询 returns 所有结果都没有 'LIMIT 10' 但是当我添加 LIMIT 10 时它给我一个错误说

Incorrect syntax near LIMIT

我错过了什么？

SELECT dbo.Organizations.cmoName AS "Organizations not quoted"
    ,dbo.Calls.kbpCallID AS "kbpCallID"
    ,MAX(dbo.CallLines.kblCallLineID) AS "kblCallLineID"
FROM (
    (
        (
            (
                dbo.Organizations LEFT OUTER JOIN dbo.Quotes ON dbo.Organizations.cmoOrganizationID = dbo.Quotes.qmpCustomerOrganizationID
                ) LEFT OUTER JOIN dbo.OrganizationIndustryTypeLinks ON dbo.Organizations.cmoOrganizationID = dbo.OrganizationIndustryTypeLinks.cmdOrganizationID
            ) LEFT OUTER JOIN dbo.Calls ON dbo.Organizations.cmoOrganizationID = dbo.Calls.kbpOrganizationID
        ) LEFT OUTER JOIN dbo.CallLines ON dbo.Calls.kbpCallID = dbo.CallLines.kblCallID
    )
WHERE dbo.Quotes.qmpQuoteID IS NULL
    AND dbo.Organizations.cmoCustomerStatus = 1
    AND dbo.OrganizationIndustryTypeLinks.cmdIndustryTypeID = 'DRAFTING  '
    AND (
        dbo.CallLines.kblAddedDate < DATEADD(dd, - 60, GETDATE())
        OR dbo.CallLines.kblCallID IS NULL
        )
GROUP BY dbo.Organizations.cmoName
    ,dbo.Calls.kbpCallID
ORDER BY dbo.Organizations.cmoName ASC LIMIT 10

Answer 1

在 SQL 服务器中：您可以使用前 10 个而不是限制，如下面的查询所示。

SELECT TOP 10 dbo.Organizations.cmoName AS "Organizations not quoted"
    , dbo.Calls.kbpCallID AS "kbpCallID"
    , MAX(dbo.CallLines.kblCallLineID) AS "kblCallLineID"
FROM (
    (
        (
            (
                dbo.Organizations LEFT OUTER JOIN dbo.Quotes ON dbo.Organizations.cmoOrganizationID = dbo.Quotes.qmpCustomerOrganizationID
                ) LEFT OUTER JOIN dbo.OrganizationIndustryTypeLinks ON dbo.Organizations.cmoOrganizationID = dbo.OrganizationIndustryTypeLinks.cmdOrganizationID
            ) LEFT OUTER JOIN dbo.Calls ON dbo.Organizations.cmoOrganizationID = dbo.Calls.kbpOrganizationID
        ) LEFT OUTER JOIN dbo.CallLines ON dbo.Calls.kbpCallID = dbo.CallLines.kblCallID
    )
WHERE dbo.Quotes.qmpQuoteID IS NULL
    AND dbo.Organizations.cmoCustomerStatus = 1
    AND dbo.OrganizationIndustryTypeLinks.cmdIndustryTypeID = 'DRAFTING  '
    AND (
        dbo.CallLines.kblAddedDate < DATEADD(dd, - 60, GETDATE())
        OR dbo.CallLines.kblCallID IS NULL
        )
GROUP BY dbo.Organizations.cmoName
    ,dbo.Calls.kbpCallID
ORDER BY dbo.Organizations.cmoName ASC

Answer 2

在 SQL 服务器中，您按照@Zip 的建议使用 TOP。

从 SQL Server 2012 开始，您可以使用 OFFSET... FETCH Read more on Offset... Fetch

SELECT dbo.Organizations.cmoName AS "Organizations not quoted"
    ,dbo.Calls.kbpCallID AS "kbpCallID"
    ,MAX(dbo.CallLines.kblCallLineID) AS "kblCallLineID"
FROM (
    (
        (
            (
                dbo.Organizations LEFT OUTER JOIN dbo.Quotes ON dbo.Organizations.cmoOrganizationID = dbo.Quotes.qmpCustomerOrganizationID
                ) LEFT OUTER JOIN dbo.OrganizationIndustryTypeLinks ON dbo.Organizations.cmoOrganizationID = dbo.OrganizationIndustryTypeLinks.cmdOrganizationID
            ) LEFT OUTER JOIN dbo.Calls ON dbo.Organizations.cmoOrganizationID = dbo.Calls.kbpOrganizationID
        ) LEFT OUTER JOIN dbo.CallLines ON dbo.Calls.kbpCallID = dbo.CallLines.kblCallID
    )
WHERE dbo.Quotes.qmpQuoteID IS NULL
    AND dbo.Organizations.cmoCustomerStatus = 1
    AND dbo.OrganizationIndustryTypeLinks.cmdIndustryTypeID = 'DRAFTING  '
    AND (
        dbo.CallLines.kblAddedDate < DATEADD(dd, - 60, GETDATE())
        OR dbo.CallLines.kblCallID IS NULL
        )
GROUP BY dbo.Organizations.cmoName
    ,dbo.Calls.kbpCallID
ORDER BY dbo.Organizations.cmoName ASC OFFSET 0 ROWS

FETCH 10 ROWS ONLY;

如果您使用 SQL 服务器，您将使用 top(10) 而不是 Limit 10。
