Question

我正在运行一个查询，其中需要SCORE为每一行提供不同的输出。我能够在每次执行时执行此操作，但是由于从varchar转换为int错误，因此RAND运气不佳。我需要每次执行时在不带小数的范围内使用可变数字。反正有这样做吗？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

                       WHERE Claims.RecordStatus = 55 AND facilityid = 40)

    USE [DATABASE NAME]
