T-SQL (SS2K8) :: How To Find All Empty Files In A Database
May 4, 2015
I need to find all empty files in the database (SQL Server 2008R2 SP2) The files become empty after the archival of a partitioned tables.
I was trying this:
select f.name, *
from sysfiles f (nolock)
left join sys.filegroups fg (nolock)
on f.name = fg.name
left join sys.indexes i (nolock)
on i.data_space_id = fg.data_space_id
left join sys.all_objects o (nolock)
ON i.[object_id] = o.[object_id]
where i.name is NULL and o.name is NULL
Did not work.
My file names are the same as the filgroup names containing the file, this is why I was joining by name.
I have a database which gets its daily feed from a ftp file. Now is there any way i can figure out the empty tables in the databese which doesnot get any data on the feed.
I would like to add to it the actual file size in mb or gb of each file to the results.
select sd.name,mf.name as logical_name,mf.physical_name, case when dm.mirroring_state is null then 'No' else 'Yes' end as Mirrored from sys.sysdatabases sd JOIN sys.master_files mf on sd.dbid = mf.database_id join sys.database_mirroring dm on sd.dbid = dm.database_id
The sp_spaceused procedure does a nice job on it's own giving me what I want (only one db though), plus a bonus allocated space column. How can I combine this sp with my other query, or is there a better way to ad this information?
Hi! I'm using replication with two database on SQL 2000,when begin, the log files size is 50mb and the data files size is 150mb. But now the log files size is 2Gb and the data files size is 4Gb. I would like to decrease the log files and the data files ??? How do i do this??? (I using Truncate and shrink doesn't change ) Thanks!!!
I added a new field to an existing ETL process which uses SSIS to ingest a CSV file. The new field in the file, Call_Transaction_ID, will not always be populated for every record and so can be NULL or empty for certain records.
Here's the problem:After the file is extracted into a staging table, the Call_Transaction_ID field is showing blank or empty when it has no ID for that particular record. The problem is when I try to then ETL this data into a fact table - I'm trying to set the Call_Transaction_ID field to -1 if it is NULL or empty, however SQL Server doesn't see the field as empty even though there is no value in the field so -1 will NEVER return.
Using a WHERE DATALENGTH(Call_Transaction_ID) = 0 returns 0 records, again because SQL Server doesn't see the field as empty or NULL.
What do I do now to get around this? How do I fix it?
declare @user varchar(30) = '' if(@user is not null or @user <> '') BEGIN print 'I am not empty' END ELSE BEGIN print 'I am empty' ENd
The output should be 'i am empty' but when i execute this i am getting ' i am not empty'. even i did browse through but i don't find the difference in my logic.

SELECT DISTINCT S.EnrollNo ,S.Name ,ET.Descriptions AS EventName ,SA.Name AS AttendStudent ,'' AS AttendFaculty FROM StudentEvent SE INNER JOIN SStudent S ON SE.PresentatorID = S.StudentID
I have a SQL Server table with nvarchar type column which has not null constraint. I am inserting empty string ("") from Java to the table column. When I export this table into .csv file using bcp tool, empty string gets written as NUL character. Is there any way I can bcp out empty string as empty string itself instead of NUL to the file?
Has anyone find solution for this problem. i also checked http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=298056&SiteID=1 and http://blogs.conchango.com/kristianwedberg/archive/2006/02/22/2955.aspx
Suppose have a Dimension table
DimColor ---------------------------- ColorKeyPK(smallint) ColorAlternateKey(nvarchar(30)) -1 UnknownMember 1 2 Blue 3 Red 4 Black
Color with the ID 1 is empty string
FactOrders --------------------------- OrderID Date Color Quantity
OrderID = 1 Color = 'Black' Quantity = 10 OrderID = 2 Color = 'Red' Quantity = 20 OrderID = 3 Color = '' Quantity = 10 OrderID = 4 Color = 'Blue' Quantity = 5 OrderID = 5 Color = Black Quantity = 10
When i use the Lookup transform it cannot find the ColorKeyPK
The result of the Lookup transform is. ------------------------------ OrderID = 1 Color='Black' ColorKey=4 OrderID = 2 Color='Black' ColorKey=3 OrderID = 3 Color='Black' ColorKey=NULL ----> This is the problem Lookup cannot find empty string. It should be 1. OrderID = 4 Color='Black' ColorKey=2 OrderID = 5 Color='Black' ColorKey=4
I have created some dynamic sql to check a temporary table that is created on the fly for any columns that do contain data. If they do the column name is added to a dynamic sql, if not they are excluded. This looks like:
If (select sum(Case when [Sat] is null then 0 else 1 end) from #TABLE) >= 1 begin set @OIL_BULK = @OIL_BULK + '[Sat]' +',' END
However, I am currently running this on over 230 columns and large tables 1.3 mil rows and it is quite slow. How I can dynamically create a sql script that only selects the columns in the table where there is data in a speedier manner. Unfortunately it has to be on the fly because the temporary table is created on the fly.
I have a Transactional table containing IDs that relate to each other. The table highlights the transactions that move one ID to another, by storing an ID and a IDNew (Basically from ID to ID).
My requirement is to create a Inline Table Valued Function that will efficiently return a single ID column to show all related IDs by looking at the ID and the IDNew fields. I need to pass in a single ID to get all relations or a list of IDs through xml.
I have managed to achieve this by making use of two recursive cte's and then combining the results with union statements to create a distinct list of values.
IF OBJECT_ID (N'tempdb..#Trans', N'U') IS NOT NULL BEGIN DROP TABLE #Trans END CREATE TABLE #Trans ( TranID int identity(1,1),
We have over 200 variants of the above, but following the same syntax (@step_name, Dbname, @Command etc...
Rules:
1) Note the unique identifier "~Z0x5F4F7B0688825E7544AC46CFD664F98AC". I would like it replaced for whatever is between "@step_name = N'" , and @command = N'DTSRun ; (this will form a filename).
2) Note the 'DTSRun /' string. I'd like that replaced with Dtexec /F "D:MyFileLocationFolderHere" (this folder remains constant).
I'm trying to find if the Saturdays worked in Bi-Weekly period is first or second, based on the Saturday occurrence the CODEID column value changes from 01 to another #, for example if it's first Saturday then CODEID changes from 01 to 02 and it's second Saturday then the CODEID changes from 01 to 03.
Below is my table, current result and desired results.
My Table:
WITH SampleData (PERSON,[HOURS],[RATE],[CODEID],[DOW],[DATE]) AS ( SELECT 1234,7.00,40.00,01,'Thursday','05/01/2014' UNION ALL SELECT 1234,8.0,40.0,01,'Friday','05/02/2014' UNION ALL SELECT 1234,3.5,40.0,01,'Saturday','05/03/2014' UNION ALL SELECT 1234,3.5,40.0,01,'Monday','05/05/2014' UNION ALL SELECT 1234,8.0,40.0,01,'Tuesday','05/06/2014' UNION ALL SELECT 1234,3.5,40.0,01,'Wednesday','05/07/2014' UNION ALL SELECT 1234,3.5,40.0,01,'Thursday','05/08/2014' UNION ALL SELECT 1234,7.0,40.0,01,'Friday','05/09/2014' UNION ALL SELECT 1234,3.0,40.0,01,'Saturday','05/10/2014' ) SELECT * FROM SampleData

What index would be best for these three queries? With best I mean the execution time, I don't care about additional space.
This is the index I currently use: create nonclustered index Ix_Data on Data (StateId, PalletId, BoxId, Id) The execution plan is SELECT (0%) - Stream Aggregate (10%) - Index Scan (90%).
Can this be optimized (maybe to use Index Seek method)?
create table isin_code ( code varchar(5), code_desc varchar(255) ) go insert into isin_code values ('aaa','aäsas') go insert into isin_code values ('aaa','as╚as') go insert into isin_code values ('aaa','aâsas') go insert into isin_code values ('aaa','asas') go
I want to identify the list of alt codes available in the table.
insert into #temp (Cabstamp,account,Document, origin, debit, credit, datalc) select 'ADM12345',111,'CMP-01','FO',1000,0, '20150110' union select 'ADM12345',112,'CMP-01','FO', 500, 0,'20150110' union select 'ADM12345',6811,'CMP-01','DO',0,1500,'20150110' union
I want to find previous date from selected date. below is the sample data.
DECLARE @StartDate SMALLDATETIME = '1/11/2016'
declare @tempdat table(repdate smalldatetime) insert into @tempdat values ('10/26/2015') insert into @tempdat values ('10/29/2015') insert into @tempdat values ('11/1/2015') insert into @tempdat values ('11/27/2015') insert into @tempdat values ('11/25/2015') insert into @tempdat values ('11/20/2015') insert into @tempdat values ('11/10/2015') insert into @tempdat values ('11/10/2015') insert into @tempdat values ('11/11/2015') insert into @tempdat values ('11/11/2015')
Now if i pass the date '10/26/2015' then i want select prev date of passed date. in this example no prev date is available, so result set would be nothing.
if i pass the date '11/10/2015' then result should be '11/1/2015' which is prev small date available in table.
I have a table with data in two columns, item and system. I am trying to accomplish is we want to compare if an item exists in 1, 2 or all systems. If it exists, show item under that system's column, and display NULL in the other columns.
I have aSQL Fiddle that will allow you to visualize the schema.
The closest I've come to solving this is a SQL pivot, however, this is dependent on me knowing the name of the items, which I won't in a real life scenario.
select [system 1], [system 2], [system 3] from ( SELECT distinct system, item FROM test where item = 'item 1' ) x pivot ( max(item)
There are plenty of scripts to do this on a per-DB level, but any that will allow me to generate a script for all DB's at once? Mine are split across dozens and it would be much easier to do a loop (using MS_ForeachDB ? )
I have three databases and 40 tables within each database on my server, for each of the tables I want to know which SSIS package generates that table. Is there a script that can do this?
If the SSIS package does not create or populate a table on the server I then want to check if there is a stored procedure that populates this.
I have created a database on SQL Express using SQL Server Manager Express. However, when I try to connect to it in Visual Studio 2005, I cannot find the .mdf file so cannot create the project datasource. Can someone tell me where it is? Searching through the files does not find it. Knowing it cannot be obtained directly and needs to be rebuilt some other way would be helpful.
I have to download the files from SFTP server, for which i am using WINSCP and i am able to successfully automate the process to download the files. But it is downloading all the files instead of only current day's files. Ihave searched for WINSCP documentation for time query parameter to pass to the get command. But its not working.
My source file name contains Datefield as "Filenameexample_150120_N001.txt".
Here 150120 mean Jan 20 2015.
Winscp has no functionality to query the files to parse using datefield. how to look for files which are from today's date.
Currently i am downloading files which contain *.* (meaning all files).
When you create data files and filegroups, you specify a size. Myquestion is -- how do you know how full they are? Is there a storedprocedure for that?
