Question

CREATE PROCEDURE SPCheckDirectoryExists
  (
     @chkdirectory as nvarchar(4000)
  )
  AS
  SET NOCOUNT ON
  BEGIN
     DECLARE @folder_exists as int
     DECLARE @file_results table(file_exists int,file_is_a_directory int,parent_directory_exists int)

    INSERT INTO @file_results
    (file_exists, file_is_a_directory, parent_directory_exists)
    EXEC MASTER.dbo.xp_fileexist @chkdirectory

    SELECT @folder_exists = file_is_a_directory
    FROM @file_results

    --script to create directory        
    IF @folder_exists = 0
     BEGIN
        EXECUTE master.dbo.xp_create_subdir @chkdirectory
        PRINT @chkdirectory +  ' created on  ' + @@servername
     END       
    ELSE
    PRINT 'Directory already exists'
END

使用上述存储过程

EXEC SPCheckDirectoryExists '\\SampleNetworkpath\Test\Test1'

它将在测试文件夹中检查并创建Test1文件夹，

如果\\SampleNetworkpath\Path投掷错误，

中没有测试文件夹

如何解决此问题，在此先感谢，

您还需要检查该目录。这样的事情，使用相同的逻辑......

CREATE PROCEDURE SPCheckDirectoryExists
  (
     @chkdirectory as nvarchar(4000)
  )
  AS
  SET NOCOUNT ON
  BEGIN
     DECLARE @folder_exists as int
     DECLARE @file_results table(file_exists int,file_is_a_directory int,parent_directory_exists int)

     DECLARE @folder_results table(file_exists int,file_is_a_directory int,parent_directory_exists int)
     DECLARE @chkdirectory2 nvarchar(4000) = reverse(right(reverse(@chkdirectory),len(@chkdirectory) - charindex('\',reverse(@chkdirectory))))
     DECLARE @folder_exists2 int

    INSERT INTO @file_results
    (file_exists, file_is_a_directory, parent_directory_exists)
    EXEC MASTER.dbo.xp_fileexist @chkdirectory

    INSERT INTO @folder_results
    (file_exists, file_is_a_directory, parent_directory_exists)
    EXEC MASTER.dbo.xp_fileexist @chkdirectory2

    SELECT @folder_exists = file_is_a_directory
    FROM @file_results

    SELECT @folder_exists2 = file_is_a_directory
    FROM @folder_results

    --script to create directory        
    IF @folder_exists = 0 and @folder_exists2 = 1
     BEGIN
        EXECUTE master.dbo.xp_create_subdir @chkdirectory
        PRINT @chkdirectory +  ' created on  ' + @@servername
     END       
    ELSE
    PRINT 'Directory already exists or parent directory was invalid'
END

使用您的逻辑的动态脚本。

CREATE PROCEDURE SPCheckDirectoryExists
(
    @chkdirectory as nvarchar(4000)
)
AS
SET NOCOUNT ON
BEGIN
    DECLARE @pos INT,@NewPath AS NVARCHAR(256) 
    WHILE(charindex('\',@chkdirectory) > 0)
    begin
        select  @pos  = CHARINDEX('\',@chkdirectory,0)  
        IF (@NewPath <> '')
            SET @NewPath = @NewPath + '\'
        SET @NewPath =ISNULL(@NewPath,'') + SUBSTRING(@chkdirectory,0,CHARINDEX('\',@chkdirectory,@pos-1)) 

        DECLARE @folder_exists as int
        DECLARE @file_results table(file_exists int,file_is_a_directory int,parent_directory_exists int) 

        INSERT INTO @file_results
        (file_exists, file_is_a_directory, parent_directory_exists)
        EXEC MASTER.dbo.xp_fileexist @NewPath

        SELECT @folder_exists = file_is_a_directory
        FROM @file_results

        --script to create directory        
        IF @folder_exists = 0
            BEGIN
            EXECUTE master.dbo.xp_create_subdir @NewPath
            PRINT @NewPath +  ' created on  ' + @@servername
            END       
        ELSE
            PRINT 'Directory already exists'

        SET @chkdirectory = SUBSTRING(@chkdirectory,@pos+1,len(@chkdirectory))
    END
END

在使用SQL xp_create_subdir中创建目录
