TSQL:一行中所有字段的值为一个字符串

时间:2011-08-22 09:33:21

标签: sql tsql

我需要将单行的所有值(而不是空值)放入一个字符串中,例如

表:

CustomerName  Address Zip
Alex          Moscow  1234

结果:

CustomerName: Alex
Address: Moscow
Zip: 1234

重要说明 - 我不知道字段名称/类型,因此它应该遍历所有字段,并且所有非空值都添加到列表中。

看起来它可以使用xquery执行此操作,但无法找到正确的语法。 任何提示?

谢谢!

select T2.N.value('local-name(.)', 'nvarchar(128)')+': '+
       T2.N.value('.', 'nvarchar(max)')
from (select *
      from YourTable
      for xml path(''), type) as T1(X)
  cross apply T1.X.nodes('/*') as T2(N)

select 'CustomerName: ' + isNull(CustometName, '') + 'Address: ' 
+ isNull(Address, ''), + 'Zip:' + isNull(Zip, '') from [TableName]

也许您需要将一些值转换为varchar

不像Mikael的解决方案那么优雅。但我还是想把它包括在内。

DECLARE @yourtable nvarchar(128)
DECLARE @sql as nvarchar(2100)
DECLARE @col as nvarchar(2000)

SET @yourtable = '<tablename>'

SELECT @col = coalesce(@col, '' ) + '+'''+t2.column_name+': '' + cast([' + t2.column_name + '] as varchar) + char(32)'
FROM INFORMATION_SCHEMA.TABLES t1 join 
INFORMATION_SCHEMA.COLUMNS t2 on t1.table_name = t2.table_name
where t2.is_nullable = 'NO' and t1.table_name = @yourtable
and t1.table_type = 'BASE TABLE' and t1.table_schema = t2.table_schema
and t2.table_schema = 'dbo'
SET  @sql = 'select ' + stuff(@col, 1,1,'') +' from ' + @yourtable
EXEC (@sql)
