最初にテーブルの構造を知らなくても、SQL Server 2008 テーブルを HTML テーブル テキストに変換する方法はありますか?
私はこれを試しました：
USE [Altiris]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[spCustomTable2HTML] (
@TABLENAME NVARCHAR(500),
@OUTPUT NVARCHAR(MAX) OUTPUT,
@TBL_STYLE NVARCHAR(1024) = '',
@HDR_STYLE NVARCHAR(1024) = '')
AS
-- @exec_str stores the dynamic SQL Query
-- @ParmDefinition stores the parameter definition for the dynamic SQL
DECLARE @exec_str NVARCHAR(MAX)
DECLARE @ParmDefinition NVARCHAR(500)
--We need to use Dynamic SQL at this point so we can expand the input table name parameter
SET @exec_str= N'
DECLARE @exec_str NVARCHAR(MAX)
DECLARE @ParmDefinition NVARCHAR(500)
--Make a copy of the original table adding an indexing columnWe need to add an index column to the table to facilitate sorting so we can maintain the
--original table order as we iterate through adding HTML tags to the table fields.
--New column called CustColHTML_ID (unlikely to be used by someone else!)
--
select CustColHTML_ID=0,* INTO #CustomTable2HTML FROM ' + @TABLENAME + '
--Now alter the table to add the auto-incrementing index. This will facilitate row finding
DECLARE @COUNTER INT
SET @COUNTER=0
UPDATE #CustomTable2HTML SET @COUNTER = CustColHTML_ID=@COUNTER+1
-- @HTMLROWS will store all the rows in HTML format
-- @ROW will store each HTML row as fields on each row are iterated through
-- using dymamic SQL and a cursor
-- @FIELDS will store the header row for the HTML Table
DECLARE @HTMLROWS NVARCHAR(MAX) DECLARE @FIELDS NVARCHAR(MAX)
SET @HTMLROWS='''' DECLARE @ROW NVARCHAR(MAX)
-- Create the first HTML row for the table (the table header). Ignore our indexing column!
SET @FIELDS=''<tr ' + @HDR_STYLE + '>''
SELECT @FIELDS=COALESCE(@FIELDS, '' '','''')+''<td>'' + name + ''</td>''
FROM tempdb.sys.Columns
WHERE object_id=object_id(''tempdb..#CustomTable2HTML'')
AND name not like ''CustColHTML_ID''
SET @FIELDS=@FIELDS + ''</tr>''
-- @ColumnName stores the column name as found by the table cursor
-- @maxrows is a count of the rows in the table, and @rownum is for marking the
-- ''current'' row whilst processing
DECLARE @ColumnName NVARCHAR(500)
DECLARE @maxrows INT
DECLARE @rownum INT
--Find row count of our temporary table
SELECT @maxrows=count(*) FROM #CustomTable2HTML
--Create a cursor which will look through all the column names specified in the temporary table
--but exclude the index column we added (CustColHTML_ID)
DECLARE col CURSOR FOR
SELECT name FROM tempdb.sys.Columns
WHERE object_id=object_id(''tempdb..#CustomTable2HTML'')
AND name not like ''CustColHTML_ID''
ORDER BY column_id ASC
--For each row, generate dymanic SQL which requests the each column name in turn by
--iterating through a cursor
SET @rowNum=0
SET @ParmDefinition=N''@ROWOUT NVARCHAR(MAX) OUTPUT,@rowNum_IN INT''
While @rowNum < @maxrows
BEGIN
SET @HTMLROWS=@HTMLROWS + ''<tr>''
SET @rowNum=@rowNum +1
OPEN col
FETCH NEXT FROM col INTO @ColumnName
WHILE @@FETCH_STATUS=0
BEGIN
--Get nth row from table
--SET @exec_str=''SELECT @ROWOUT=(select top 1 ['' + @ColumnName + ''] from (select top '' + cast(@rownum as varchar) + '' * from #CustomTable2HTML order by CustColHTML_ID ASC) xxx order by CustColHTML_ID DESC)''
SET @exec_str=''SELECT @ROWOUT=(select ['' + @ColumnName + ''] from #CustomTable2HTML where CustColHTML_ID=@rowNum_IN)''
EXEC sp_executesql
@exec_str,
@ParmDefinition,
@ROWOUT=@ROW OUTPUT,
@rowNum_IN=@rownum
SET @HTMLROWS =@HTMLROWS + ''<td>'' + @ROW + ''</td>''
FETCH NEXT FROM col INTO @ColumnName
END
CLOSE col
SET @HTMLROWS=@HTMLROWS + ''</tr>''
END
SET @OUTPUT=''''
IF @maxrows>0
SET @OUTPUT= ''<table ' + @TBL_STYLE + '>'' + @FIELDS + @HTMLROWS + ''</table>''
DEALLOCATE col
'
DECLARE @ParamDefinition nvarchar(max)
SET @ParamDefinition=N'@OUTPUT NVARCHAR(MAX) OUTPUT'
--Execute Dynamic SQL. HTML table is stored in @OUTPUT which is passed back up (as it's
--a parameter to this SP)
EXEC sp_executesql @exec_str,
@ParamDefinition,
@OUTPUT=@OUTPUT OUTPUT
RETURN 1
しかし、プロシージャを実行すると
DECLARE @HTML NVARCHAR(MAX)
EXEC SpCustomTable2HTML 'Users', @HTML OUTPUT
SELECT @HTML
それは戻ってきnullます。
何か案は？
