将您的行标准移动到外部选择

SELECT * FROM (SELECT ROW_NUMBER() OVER (ORDER BY hrl.Frn) as Row,
     ...
               WHERE hc.Entity_Type = 'L'  AND hrl.LicenseStatusId IN (1)
              ) T
WHERE T.Row >=1 and T.Row <= 20)

您可以使用CTE执行此操作:

WITH NumberedRows AS
(
    SELECT 
        ROW_NUMBER() OVER (ORDER BY hrn.Frl) AS RowNum,
        ...
    WHERE 
        hc.Entity_Type = 'L'
        AND hrl.LicenseStatusId IN (1)
)
SELECT
    *
FROM
    NumberedRows
WHERE
    RowNum <= 20

检查您使用的是哪个版本的sql server数据库。 row_number是从sql server 2005开始添加的。它不支持sql server 2000

您不能在where子句中为列使用别名,因为where子句是在Select子句之前处理的。

已编辑:

您也可以在where子句

中添加子查询
Where ((SELECT ROW_NUMBER() OVER (ORDER BY hrl.Frn)) < 20,

或根本不使用Row_Number,

Where (Select Count(*) 
From dbo.sbi_f_HldrRgstrtnLcns 
Where Frn < hrl.Frn) < 20
