Passing Variables

  • Hi,

    I have become a bit stuck with this script I am building, any help would be appreciated.

    DECLARE @Date nvarchar (100),

    @sql nvarchar (4000),

    @SQL2 nvarchar (4000)

    Set @Date = 'IRR_HBDE_PRD'+'_db_' + convert(varchar, getdate(), 102)

    IF OBJECT_ID('tempdb..#DirectoryTree') IS NOT NULL DROP TABLE #DirectoryTree;

    CREATE TABLE #DirectoryTree (id int IDENTITY(1,1),subdirectory nvarchar(512),depth int,isfile bit);

    INSERT #DirectoryTree (subdirectory,depth,isfile)EXEC master.sys.xp_dirtree 'O:\MSSQL10_50.LIVE910MSSQL\MSSQL\Backup\SQLRestores\IRR_HBDE_PRD',1,1;

    set @sql = 'SELECT subdirectory FROM #DirectoryTree WHERE isfile = 1 AND RIGHT(subdirectory,4) = ''.BAK''

    AND subdirectory LIKE '''+@Date+'%'''

    PRINT @sql

    SET @SQL2 = 'RESTORE DATABASE [IRR_HBDE_PRD1] FROM DISK = N''O:\MSSQL10_50.LIVE910MSSQL\MSSQL\Backup\SQLRestores\IRR_HBDE_PRD\'+@SQL+''' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10'

    PRINT @SQL2

    The output I get is below but the part in bold should be the backup file name, how can I correct this?:

    SELECT subdirectory FROM #DirectoryTree WHERE isfile = 1 AND RIGHT(subdirectory,4) = '.BAK'

    AND subdirectory LIKE 'IRR_HBDE_PRD_db_2014.01.19%'

    RESTORE DATABASE [IRR_HBDE_PRD1] FROM DISK = N'O:\MSSQL10_50.LIVE910MSSQL\MSSQL\Backup\SQLRestores\IRR_HBDE_PRD\SELECT subdirectory FROM #DirectoryTree WHERE isfile = 1 AND RIGHT(subdirectory,4) = '.BAK'

    AND subdirectory LIKE 'IRR_HBDE_PRD_db_2014.01.19%'' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10

  • Bit hard for me to check if this works, but what you're looking to do is populate a variable with the returned result from the query. At the moment you're just populating the variable with the statement

    DECLARE @Date nvarchar (100),

    @sql nvarchar (4000),

    @SQL2 nvarchar (4000)

    Set @Date = 'IRR_HBDE_PRD'+'_db_' + convert(varchar, getdate(), 102)

    --Add wildcard to end of variable

    SELECT @Date = RTRIM(@Date) + '%';

    SELECT @Date;

    IF OBJECT_ID('tempdb..#DirectoryTree') IS NOT NULL DROP TABLE #DirectoryTree;

    CREATE TABLE #DirectoryTree (id int IDENTITY(1,1),subdirectory nvarchar(512),depth int,isfile bit);

    INSERT #DirectoryTree (subdirectory,depth,isfile)EXEC master.sys.xp_dirtree 'O:\MSSQL10_50.LIVE910MSSQL\MSSQL\Backup\SQLRestores\IRR_HBDE_PRD',1,1;

    --set @sql = 'SELECT subdirectory FROM #DirectoryTree WHERE isfile = 1 AND RIGHT(subdirectory,4) = ''.BAK''

    --AND subdirectory LIKE '''+@Date+'%'''

    --Populate variable with result not statement

    set @sql = (SELECT subdirectory FROM #DirectoryTree WHERE isfile = 1 AND RIGHT(subdirectory,4) = '.BAK'

    AND subdirectory LIKE @Date)

    PRINT @sql

    SET @SQL2 = 'RESTORE DATABASE [IRR_HBDE_PRD1] FROM DISK = N''O:\MSSQL10_50.LIVE910MSSQL\MSSQL\Backup\SQLRestores\IRR_HBDE_PRD\'+@SQL+''' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10'

    PRINT @SQL2

    This get you roughly where you want?

  • you my friend are a hero!

    For some reason I couldn't get my head around it.

    Thank you.
