Question

我在SQL Server中编写查询以显示上周收到的所有作业，该查询将成为Crystal Report中自动报告的基础，语法如下

SELECT TOP (100) PERCENT 
    DATENAME(yy, dbo.JOB.JOB_TAKEN_DATE) + '-' + DATENAME(wk, DATEADD(wk, - 1, dbo.JOB.JOB_TAKEN_DATE)) AS PERIOD,
    dbo.JOB.CUST_ORD_NO AS [ORDER NO],
    dbo.JOB.JOB_TAKEN_DATE AS RECEIVED,
    dbo.JOB.JOB_COMPLETION_DATE AS COMPLETED,
    UPPER(ISNULL(dbo.JOB.PROPERTY_LOCATION, ' ') + ' ' + dbo.JOB.PROPERTY_NAME + ' ' + REPLACE(REPLACE(REPLACE(dbo.JOB.PROPERTY_ADDRESS, CHAR(10), ' '), CHAR(13), ' '), CHAR(9), ' ') + ' ' + dbo.JOB.PROPERTY_POSTCODE) AS ADDRESS,
    REPLACE(REPLACE(REPLACE(dbo.JOB.WORKS_TO_BE_CARRIED_OUT, CHAR(10), ' '), CHAR(13), ' '), CHAR(9), ' ') AS [WORKS ORDERED],
    dbo.JOB.JOB_TARGET_DATE,
    dbo.['TMO properties$'].F2 
FROM
    dbo.JOB 
INNER JOIN 
    dbo.CUSTOMERPROPERTY ON dbo.JOB.CUSTOMER_PROPERTY_ID = dbo.CUSTOMERPROPERTY.CUSTOMER_PROPERTY_ID 
INNER JOIN 
    dbo.['TMO properties$'] ON dbo.CUSTOMERPROPERTY.EXTERNAL_REFERENCE = dbo.['TMO properties$'].F1 
WHERE
    DATENAME(yy, dbo.JOB.JOB_TAKEN_DATE) + '-' + DATENAME(wk, DATEADD(wk, - 1, dbo.JOB.JOB_TAKEN_DATE)) = DATENAME(yy, CURRENT_TIMESTAMP) + '-' + DATENAME(wk, DATEADD(wk, - 1, CURRENT_TIMESTAMP)) 
ORDER BY
    RECEIVED

运行查询时出现错误

在日期＆＃39;中添加值列导致溢出

谁能看到我做错了什么？

Answer 1

您提供的代码中唯一可能出现错误的地方是：dateadd(week, -1, j.job_taken_date)，select和where中都会显示错误。

您可以使用datepart()获取week整数并将其减少1而不是使用date调整convert(varchar(2),datepart(week,j.job_taken_date)-1)值来解决此问题。

看起来你的where条款意味着＆＃34;本周采取的工作＆＃34;。如果是这种情况，您可以简化where以比较截断到一周的日期，而不是现在正在构建的字符串比较，这可能会导致您的错误。

您还可以使用表别名使查询更容易阅读，而不是使用日期/时间操作的简写。

select top (100) percent 
    datename(year, j.job_taken_date) 
    + '-' 
    --+ datename(week, dateadd(week, -1, j.job_taken_date)
    + convert(varchar(2),datepart(week,j.job_taken_date)-1)
    ) as period
  , j.cust_ord_no as [order no]
  , j.job_taken_date as received
  , j.job_completion_date as completed
  , upper(isnull(j.property_location, ' ') 
    + ' ' + j.property_name + ' ' 
    + replace(replace(replace(j.property_address, char(10), ' '), char(13), ' '), char(9), ' ') 
    + ' ' + j.property_postcode
    ) as address
  , replace(replace(replace(j.works_to_be_carried_out, char(10), ' '), char(13), ' '), char(9), ' '
    ) as [works ordered]
  , j.job_target_date
  , tmop.F2
from dbo.job j
  inner join dbo.customerproperty cp
    on j.customer_property_id = cp.customer_property_id
  inner join dbo.['tmo properties$'] tmop
    on cp.external_reference = tmop.F1
where dateadd(week, datediff(week, 0, j.job_taken_date), 0)
    = dateadd(week, datediff(week, 0, current_timestamp), 0)
order by received

WHERE子句的问题
