Question

我似乎无法弄清楚为什么这在MS SQL Server中不起作用。它似乎没有分组线。具体来说，我看到了：

1036 SC

1036 S1

1094 VO

1094 V1

1094 V2

我希望看到：

1036 SC，S1

1094 VO，V1，V2

有人可以看到语法错误吗？

SELECT DISTINCT oa.acct_cd AS [Account], 
                STUFF((SELECT ',' + CASE WHEN o.trans_type like 'BUY%' then 'buy of ' else 'sell of ' end + s.ticker AS [text()]
                       FROM [dbo].[synCRtblTS_ORDER] o INNER JOIN [dbo].[synCRtblCSM_SECURITY] s 
                       ON o.SEC_ID = s.SEC_ID
                       WHERE o.ORDER_ID = oa.ORDER_ID AND o.status IN ('OPEN','WORK','PENDING')
                       FOR XML PATH('')), 1, 1, '') [buy/sell]
FROM [dbo].[synCRtblTS_ORDER_ALLOC] oa INNER JOIN tblPortfolio p
ON oa.ACCT_CD = p.Account INNER JOIN tblInvestmentObjective io
ON io.Code = p.InvestmentObjective
WHERE p.AsOfDate = (SELECT AsOfDate FROM tblDateAsOf) and io.CashMgmtStrategy IN ('SC','VO')
GROUP BY oa.ORDER_ID, oa.acct_cd
order by 1

Answer 1

您提供的信息不够......在您的STUFF中，您创建（并连接）应包含“buy of”或“sell of”的字符串。您在输出中缺少此信息。

猜测您的SC，S1，VO值是CashMgmtStrategy条目。你没有连接它们......

如果您对表格没有更深入的了解，我无法解决您的问题，但在此您可以通过FOR XML和STUFF

找到连接的工作示例

此代码将在逗号分隔列表中列出所有表的名称及其列。

SELECT DISTINCT tbls.name AS TableName,
                STUFF(
                    (
                     SELECT ', ' + cols.name
                     FROM sys.columns AS cols
                     WHERE cols.object_id  = tbls.object_id
                     FOR XML PATH('')
                     ), 1, 2, '')  AS ColumnList
FROM sys.tables AS tbls

这个FOR XML路径有什么错误
