Shrink DB And Create Backup Thru VB.NET Code
Jun 14, 2006
Hi,
Is it possible to shrink a DB thru .NET.
Presently I have to go into the SQL server 2005 studio to shrink the DB.
To shrik the DB I right click on the DB and select all tasks -> Shrink -> DB
How would I do this thru SQL codse?
I would like to do it thru my VB.NET code as you would compact an ACCESS DB.
The reason I want to set it thru my code is :
The clients that use my program have no clue of
SQL or for that matter computer itself.
I just want them to click on a button on my application which should
do the shrinking.
Similarly for backup of the DB.
Tnx

I am a bit confused. I was told that backing up the TLog cleared out all the commited transactions which shrinks the log. Is this true, becuase I started with a 72 gig transaction log and the created a maint plan to back it up as a .trn. After this was successful the 72gig .ldf was still the same size. What am I doing wrong to get this log size down?
Thanks!

Hi,
I am in the process of migrating databases from a SQL Server 2000 server to a 2005 server.
I have taken full backups and restored without recovery on the 2005 server. I now need to take transaction log backups and restore with recovery tonight to complete the operation. My question is this:
Some of the transaction logs have grown very large. Is it safe practice to perform a backup tran with truncate only and then run dbcc shrinkfile to reduce the size before I back up? This would make the process much quicker.
Thanks.

I'm running full recovery mode and doing log shipping so changing to simple mode is not an option.
I'm running BACKUP LOG right before and when I check it says my log is 99% free (on a 180GB log).
When I do DBCC LOGINFO('dbname') right before and after I see a dozen entries and they are all over the file and not just at the starting offset areas. The BACKUP LOG doesn't clean out the file completely.
Is there any explanation for this? Even though I'm doing this at off hours, is it possible that someone on the site in that split second is putting new entries in the log? Why are they spread out though? If they just put entries at the beginning I could shrink the file to a normal size still.

Help,I have a database that has a data file of 2GB and a log file of 31GB.In enterprise manager, when I choose shrink it says there is 30GB ofunused space. When I shrink the database, it does not shrink,(however it says it has completed).I've done a complete backup, tried shrink again, no dice. I thenbacked up the database (which the backup was 1.9GB), deleted thedatabase and made a new database with 2,048MB for the data and samefor the log file.When I restore, the log file jumps up to 31GB again. When I check thespace when I use the shrink, it again says I have 30GB of unusedspace.How on earth do I get this file to shrink?I've been able to shrink other databases, but not this one.TIARob

Hi, I want to create a database setup on a server. I've scripted my database from sql server express. I've tested the code in the query window and it worked.

Here is a chunk of the script.USE [master]GO/****** Object: Database [estate_management] Script Date: 09/13/2006 09:19:32 ******/CREATE DATABASE [estate_management] ON PRIMARY ( NAME = N'estate_management', FILENAME = N'D:MSSQLestate_management.mdf' , SIZE = 2048KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB ) LOG ON ( NAME = N'estate_management_log', FILENAME = N'D:MSSQLestate_management_log.ldf' , SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%) COLLATE SQL_Latin1_General_CP1_CI_ASSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOIF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[admin]') AND type in (N'U'))BEGINCREATE TABLE [dbo].[admin]( [admin_id] [int] IDENTITY(1,1) NOT NULL, [log_in_id] [varchar](20) NOT NULL, [password] [varchar](50) NOT NULL, CONSTRAINT [PK__admin__07020F21] PRIMARY KEY CLUSTERED ( [admin_id] ASC)WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF, FILLFACTOR = 1) ON [PRIMARY], CONSTRAINT [IX_admin] UNIQUE NONCLUSTERED ( [admin_id] ASC)WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]) ON [PRIMARY]END Thanks for your time.

Hi
I wonder if it is possible to create a dataset in code and then feed it to a Reporting Svcs (RS) report and have it rendered on the data from this dataset.
My collegues does this with Crystal and it would break my heart if I cant do this with (RS)...
I have tried to find a solution but so far, no luck.
Anyone have any ideas?

I have some SQL code as inline SQL (bad habit, I know). Now I want to convert this to an sproc, but I'm pretty much out of ideas here. The code looks like this:
string SQL = "SELECT * FROM MyDBTable WHERE 1=1";
if (txtMyField1.Text != "")
{
SQL = SQL + " AND MyField1 = @MyField";
}
if (txtMyField2.Text != "")
{
SQL = SQL + " AND MyField2 LIKE '%'+ @MyField2 + '%'";
}
if (txtMyField3.Text != "")
{
SQL = SQL + " AND MyField3 LIKE '%' + @MyField3 + '%'";
}
I have an search page built on ASP.NET 2.0. Based on what the user has entered to the form fields, the SQL in constructed on the fly. Since this is now inside codebehind file (aspx.cs), I want to get rid of it and move it to an sproc. But the question is how ? Some simple SQL clauses are easy to convert to an sproc but this is causing me lots of issues.

Hi all,My program is a central data processing application built in ASP.We have different companies that use different web pages on another webapplication (from different countries) to load some inventory data(merchandise - clothes).Here is my requirement: Load different types of data (in differentformats) into a common set of tables, to do this I have to firstfilter, do lookup's, use cross-reference tables on this data and thenload it into a couple of tables.Since data is so different everytime, I want to have one main storedprocedure in which I can build the table (I know the format of thisdata so I know what columns/types to create) into which I will feed thedata.After this I will create other stored procs/udf's that reference thistable (probably from the same main stored proc) 'cleanse' the databefore loading into the actual tables.How feasible is my approach? (if you can call it one :-) I do not wantto have seperate tables for each country, that will be too many and sothis plan...If not any other ideas will be really helpful.thanks much

I have been reading up on everything I can find on this subject and I am not clear if this is allowed within the SQL Server 2005 CLR. My function calls work within a Windows form project, but don't run when invoked from a SQL function. I don't get any errors or warnings when creating the assembly and functions within SQL Server, but when running via a select statement, the spid just hangs and I have to stop & restart the service to kill the process. I have been investigating the security settings for this assembly, but I think I have that covered via the RunTime Security Policy settings in the .NET Framework 2.0 Configuration tool.
Any insights, knowledge, or thoughts would be greatly appreciated.

My Execute SQL Task will store the file name into a variable(mFile) of type string datatype.
Now I wanted a script task (C# code) to create a filename from the variable (mFile) value.
Since it is a common issue I tried a lot in the internet but none of the queries worked.

Below is code I am using to create a heatmap in SSRS. THe code seems to be working well except for one glitch. Sometimes numbers in the "middle of the pack" are white. Obviously they should be one the of colors listed below. Why numbers would be white when I declared only white for IsNothing.Â
 Public Function GetHeatmapColor(ByVal textBoxValue, ByVal minDataSetValue, ByVal maxDataSetValue) As String
    Dim colours As String() = New String() {"White","DarkGreen","Green","ForestGreen","LimeGreen","YellowGreen","Yellow","Gold","Orange","DarkOrange","OrangeRed","Red"}
        If IsNothing(textBoxValue) = True Then
      Return colours(0)

3) HO20150624.txt
2015-06-24 00:00:00.000Â HOÂ 20150701Â 43
And so on..
But the requirement is to have a dynamic query where we can have more number of Codes or less number of codes and similarly the package should generate dynamic text files, one .txt file per code. What is the best way to create a package which can meet the above requirement?

If you have problems shrinking a transaction log no matter what commands you issue, here's a way to shrink the tranlog:
1. Right click on the properties of the database and go to the options tab.
2. Change the recovery mode to simple.
3. Right click again on the database - go to all tasks - shrink database.
4. Shrink the database.
5. Change the recovery mode back to what you had it as.
I found this out by trial and error as I could not find any documentation on it and no matter what I tried, I could not get the transaction log to shrink.

Hi GuysOff late, I've grown with programming that requires more than a number of tables that has foreign keys with other tables' primary keys. It takes a really cumbersome coding to retrieve the code from another table with the other table having foreign keys. My question is, how do we program VS 2005 such that it does all the retrieval of the data from the database instead of us writing the code all by ourself?Is it really good database technique to bend the normalcy rules and have one to two columns having redundant data?Can anyone tell me how to write code that retrieves the foreign key data when the data from the other table is called?Thanks

Hi,
I was wondering if someone could help me. I'm having problems using backup in Enterprise Manager, the backup continually fails and points to a hardware problem. However, I have been able to backup files using different software to tape which rules out hardware.
I'm trying to create a new backup device incase the problem lies there but I receive the error 'error15061: Add device request denied. A physical device named '%s' already exists'
Any ideas?
Cheers

Hi,
I am trying to create a script that will create a backup (or copy) of an sdf database.
I have a database already in my application working nicely and want the user to have the option to backup that file so if anything goes wrong they will be able to click a button and it will restore all the data to the database. I am not sure which options are best for me. there are 3 main ones i have considered, these are:
1) Create a text file with all the data in it.
2) Create a HTML file with the data in it.
3) Create an xml file with the data in it.
Help would be appreciated. Thanks =]

I know this is easy but I am having trouble creating a database from a backup file.
I created a database (Test).
Then I selected 'Test', went to Tasks and selected 'Restore Database'.
I selected 'Device' browsed to the backup file.
I choose the destination database to be 'Test'.
There is no backup sets listed to restore. The 'OK' button is disabled.
How do you get the backup list to display? This is a new database. I don't need a backup.
