Question

使用Sql Server 2005和tsql，我正在寻找一种方法将任何查询的结果（例如select * from Person.Address）转换为大字符串，例如：

AddressID       AddressLine1            AddressLine2
1               1970 Napa Ct.           NULL        
2               9833 Mt. Dias Blv.      NULL        
3               7484 Roundtree Drive    NULL        
4               9539 Glenside Dr        NULL        
5               1226 Shoe St.           NULL

光标是否可行？ 我希望机制是通用的，以便它可以将任何查询的结果转换为字符串。

<强>查询：

SET NOCOUNT ON;

DECLARE 
       @SQL NVARCHAR(MAX)
     , @TableName SYSNAME = 'Person.Address'

SELECT @SQL = 'SELECT STUFF((SELECT CHAR(10) +
' + STUFF((
     SELECT [text()] = CHAR(10) + '+ CAST(' + c.name + ' AS CHAR(' + CAST(
                    CASE WHEN c.max_length = -1 OR TYPE_NAME(c.system_type_id) = 'uniqueidentifier' 
                              THEN 150 
                              ELSE (c.max_length / 2) + 5
                    END AS VARCHAR(10)) + '))'
     FROM sys.columns c
     WHERE c.[object_id] = OBJECT_ID(@TableName)
          AND c.user_type_id = c.system_type_id
FOR XML PATH('')), 1, 2, ' ') + ' 
FROM ' + @TableName + '
FOR XML PATH('''')), 1, 1, '''')'

DECLARE @temp TABLE (t VARCHAR(MAX))

INSERT INTO @temp
EXEC sys.sp_executesql @SQL

DECLARE @SQL2 VARCHAR(MAX)

SELECT @SQL2 = t
FROM @temp

PRINT @SQL2

Answer 2

使用STUFF（）。试试这个

  SELECT STUFF((SELECT  ' ' + (cast(AddressID  as varchar(10))+','+
                              cast(AddressLine1   as varchar(500))+','+
                              cast(AddressLine1   as varchar(500)))
  FROM Person.Address
  FOR XML PATH('')), 1, 1, '')

将任何查询结果转换为字符串
