我正在尝试编写一个存储过程来执行文件夹中的所有.sql
个文件,然后将结果输出到CSV文件。
我的代码:
DECLARE @Table table(
[FileName] varchar(100),
depth int,
isFile int
)
DECLARE @Result int
DECLARE @FileName VARCHAR(100)
DECLARE @exportFile VARCHAR(100)
DECLARE @ExportPath VARCHAR(100)
DECLARE @SQLText VARCHAR(MAX)
DECLARE @FilePath VARCHAR(100)
DECLARE @FULLPATH VARCHAR(200)
DECLARE @BULKEXEC NVARCHAR(MAX)
DECLARE @Cmd nvarchar(1000)
SET @FilePath = 'c:\temp'
SET @ExportPath = 'c:\temp\output'
INSERT INTO @Table
EXEC master..xp_dirtree @FilePath,1,1
DELETE FROM @Table WHERE isFile=0
DECLARE FileList CURSOR STATIC FOR SELECT [FileName] FROM @Table WHERE FileName LIKE '%.sql'
OPEN FileList
FETCH FIRST FROM FileList INTO @FileName
WHILE @@Fetch_Status = 0
BEGIN
SET @exportFile = REPLACE(@FileName,'.sql','.csv')
SET @FULLPATH = @FilePath + '\' + @FileName
SET @BULKEXEC = 'SELECT @SQLText = BulkColumn FROM OPENROWSET(BULK ''' + @FULLPATH + ''', SINGLE_BLOB) as x'
EXEC sp_ExecuteSQL @BULKEXEC, N'@SQLText VARCHAR(MAX) output ', @SQLText output
EXEC (@SQLText)
SET @Cmd = 'bcp "SELECT * FROM ##Temptable" queryout "' + @ExportPath + '\' + @exportFile + '" -c -t, -T'
EXEC @Result = master..xp_cmdshell @cmd
FETCH NEXT FROM FileList INTO @FileName
END
CLOSE FileList
DEALLOCATE FileList
目前执行这些文件,但我错过了将结果上传到##Temptable
的中间位。
有人能帮忙吗?

看一下下面的例子。它使用@sqltext
中的查询,这是一个非常通用的查询,用于从INFORMATION_SCHEMA
架构(tables
和columns
)中选择信息。
然后修改此查询以将结果插入到全局临时表##tt
中,方法是查找第一个FROM
关键字并在适当的位置插入INTO ##tt
。执行修改后的查询以将查询结果插入临时表中。
最后,使用带有xp_cmdshell
命令的BCP
过程将结果写入文本文件。
DECLARE @i INT=1;
WHILE @i<10
BEGIN
DECLARE @sqltext NVARCHAR(MAX);
IF @i%2=1
SET @sqltext='SELECT*FROM INFORMATION_SCHEMA.tables';
ELSE
SET @sqltext='SELECT*FROM INFORMATION_SCHEMA.columns';
DECLARE @ii INT; SET @ii=CHARINDEX('FROM',@sqltext);
SET @sqltext=LEFT(@sqltext,@ii-1)+' INTO ##tt '+SUBSTRING(@sqltext,@ii,LEN(@sqltext));
EXEC(@sqltext);
DECLARE @bcp_cmd NVARCHAR(4000);
SET @bcp_cmd='BCP "SELECT*FROM ##tt" QUERYOUT "c:\temp\tt'+CAST(@i AS NVARCHAR)+'.txt" -c -t, -T -d ' + DB_NAME() + ' -S '+ @@SERVERNAME;
EXEC xp_cmdshell @bcp_cmd;
DROP TABLE ##tt;
SET @i=@i+1;
END
如果无法格式化.sql
文件中的查询,因为它们是复杂的脚本,sqlcmd实用程序将更容易使用。您可以使用-i
指定输入文件(SQL脚本),使用-o
指定输出文件(CSV文件)。 -s
用于列分隔符,依此类推。

如果其他人想要做类似的话,我的工作代码如下:
DECLARE @Table table(
[FileName] varchar(100),
depth int,
isFile int
)
DECLARE @Result int
DECLARE @FilePath VARCHAR(100)
DECLARE @FileName VARCHAR(100)
DECLARE @Fullpath VARCHAR(200)
DECLARE @exportFile VARCHAR(100)
DECLARE @ExportPath VARCHAR(100)
DECLARE @FullExportPath AS VARCHAR(200)
DECLARE @Cmd nvarchar(1000)
SET @FilePath = '\\192.168.7.111\c$\temp'
SET @ExportPath = '\\192.168.7.111\c$\temp\output'
INSERT INTO @Table
EXEC master..xp_dirtree @FilePath,1,1
DELETE FROM @Table WHERE isFile=0
DECLARE FileList CURSOR STATIC FOR SELECT [FileName] FROM @Table WHERE FileName LIKE '%.sql'
OPEN FileList
FETCH FIRST FROM FileList INTO @FileName
WHILE @@Fetch_Status = 0
BEGIN
SET @exportFile = REPLACE(@FileName,'.sql','.csv')
SET @FullExportPath = @ExportPath + '\' + @exportFile
SET @Fullpath = @FilePath + '\' + @FileName
SET @cmd = 'sqlcmd -i "' + @Fullpath + '" -o "' + @FullExportPath + '" -h-1 -s"," -W'
EXEC @Result = master..xp_cmdshell @cmd
FETCH NEXT FROM FileList INTO @FileName
END
CLOSE FileList
DEALLOCATE FileList
