SQL Server：为每个输出行生成不同的值

Question

我正在运行一个查询，其中我需要SCORE为每一行提供不同的输出。我能够按执行执行但是我没有运气，因为我从varchar转换为int错误。我需要在没有小数的范围内每次执行变量数。反正有没有这样做？任何帮助表示赞赏。

SELECT
    'Row_Number^FEED_date^database_id^station_id^Form_Type^FBCS_CLAIM_ID^FBCS_LINE_ID^Pay^SCORE^score_date^reason_code^reason_description'
UNION ALL
SELECT
    CAST(ROW_NUMBER() OVER ( ORDER BY ( SELECT 1 ) ) AS VARCHAR(20))  + '^' + 
          CONVERT(VARCHAR, getdate(), 112)+ '^' +  
          'FBCSTrans'+ '^' +  ---took off the 1 so if problems put it back
          stationnumber+ '^' +  
          case when claimtype = 0 then 'HCFA 1500' else 'UB 1450' end+ '^' + 
          CAST(Claims.claimid AS VARCHAR(50)) + '^' + 
          CAST(LineID AS VARCHAR(50)) + '^' + 
          'Y'+ '^' + 
          **RAND() * 100000 AS random_number** + '^' + 
          CONVERT(VARCHAR, getdate(), 112)+ '^' + 
          '' + '^' + ''
FROM 
    Claims 
JOIN 
    ClaimLines ON Claims.Claimid = Claimlines.Claimid 
JOIN 
    Facilities ON Claims.FacilityID = Facilities.FacilityID
WHERE  
    Claims.ClaimId IN (SELECT TOP(100000) ClaimId 
                       FROM CLAIMS 
                       WHERE Claims.RecordStatus = 55 AND facilityid = 40)
