Re: question on using transaction Selahattin Bostanci20-Jul-05 22:35 Selahattin Bostanci 20-Jul-05 22:35  sure necessary especially if your writing operation has several steps. think about if you get an error while inserting or deleting a record related to several tables. there would sure remain some unnecessary data in tables. (records that have been deleted or inserted before getting the error.) Re: question on using transaction ppp00121-Jul-05 3:38 ppp001 21-Jul-05 3:38  Thanks for your reply. But my program is not for enterprise application, just for desktop single user. Is this still necessary coz the addition of transaction into my program will cause a lot of effort ? So are application like MSWord,...also adopts transactions ? Re: question on using transaction Selahattin Bostanci21-Jul-05 4:13 Selahattin Bostanci 21-Jul-05 4:13  its up to you but if i were you i would use transaction.

Re: question on using transaction Rob Graham21-Jul-05 5:33 Rob Graham 21-Jul-05 5:33  MSWord is not a database, so it neither supports not needs transactions. If you are making multiple related changes to multiple taples (for example: insert new row in main table, insert new row(s) in detail table using foreign key from new row in main table) you should always enclose these in a single transaction, so that if one of the dependant changes fails (an unexpected null value, an out of range value, etc. ) you can easily cancel the preceding changes (rollback the transaction). Adding the transaction support is relatively easy, and should not take much code, Transactions really have nothing to do specifically with multi-user scenarios, instead the have to do with keeping changes consistent - preventing partial updates that could corrupt the data.

Eric Hoffer How to create item that could be null in access? rushing19-Jul-05 22:50 rushing 19-Jul-05 22:50  When creating table in access, the default item is not null. How to create item which could be null? Thanks! Re: How to create item that could be null in access? Rob Graham20-Jul-05 3:39 Rob Graham 20-Jul-05 3:39  Open the table in design view. Select the field in which you wish to allow nulls set the "Required" entry to "no". If the field is a text or memo type, you may also want to set "allow zero length" to yes (this allows an empty string as a value, not the same as a null).

Thought to let you know! Al Re: sql log file Rob Graham20-Jul-05 8:01 Rob Graham 20-Jul-05 8:01  What is the recovery model set to? Unless it is 'simple', the log file will not be automatically truncated, but will continue to grow until you truncate it either by issuing a 'backup log with truncate only' or by making a full backup and truncating the log as part of the backup command. Otherwise all changes are saved for possible use in restoring the database changes since the last backup. The 'simple' recovery model says you are only going to depend on backups and won't use logs for restore, so the log will be truncated as soon as changes are commited.

Eric Hoffer Getting actual size of a DataType Narly19-Jul-05 16:31 Narly 19-Jul-05 16:31  Hi Folks, Using MS-SQL Server 2000 Windows XP Pro VB 6 I need to find the actual data size for a nvarch, datefields, money etc.. using a SQL Statement. When I use the 'sp_column' command in SQL Server it doesn't tell me the actual field length that has been defined for the Table. Does anyone have a SQL Statement that can give me the correct field size. If you look at the table definition is Enterprise Manager it shows me the correct values. Just need to replicate this info into a sql statement. Cheers, Narly..

Edmund Burke DatePart and User Defined Function samoore19-Jul-05 12:10 samoore 19-Jul-05 12:10  I want to know if you can call a store procedure in a datepart function. I am trying to pass the datepart dates that are created by a stored procedure. I am not sure that this is even possible. My main goal is to count work days between two given dates. I thought I could use the datepart function to count the 6th and 7th day. Than I could subtract their totals from the final count. The code I am trying is below. select datepart(weekday, dbo.sp_work_day_count '45') Scott Moore Developer Urgently need help for inserting value from .net CF to SQL CE database Member 193588019-Jul-05 8:39 Member 1935880 19-Jul-05 8:39  Hi, I currently faced a problem on inserting decimal value from vb .net into SQLCE which declared as money data type.

Migrating SQL Server to access database using DTS Martin@captivasystems19-Jul-05 6:00 Martin@captivasystems 19-Jul-05 6:00  How can I use DTS to migrate some tables and views from SQL server to a new access database? I want to be able to do this programmatically, so that the windows application user can create an access database from an existing SQL server. Thanks, Martin Re: Migrating SQL Server to access database using DTS Yulianto.19-Jul-05 16:45 Yulianto. 19-Jul-05 16:45  Search for "creating package dts" or see the samples in SQL Server manual. Or google for it. I found this[^] and this.[^]. Is this help? <italic>Work hard, Work effectively. Re: Migrating SQL Server to access database using DTS Selahattin Bostanci19-Jul-05 21:36 Selahattin Bostanci 19-Jul-05 21:36  Just create your dts package with sql server and then have look at this article. http://sqldev.net/DTS/DotNETCookBook.htm[^] Article is about calling dts packages programatically with .NET.

There will be a defined instance in each case, so all servers to be found will be of the form "machinename\myinstance" - I just need to find possible values for 'machinename'. (pretty much like the facility in Enterprise Manager for finding a new server registration). We are using C# (.NET 2003) but I can translate from other methods if required.
