Prevent Insert && Update If Field &&"archived&&" = True
Hi,
I've got a table containing calculated values, so i created a field named "archived" (bit datatype) on this table, to prevent the values to be updated if this field is set to true.
Is it possible to created a constraint, to prevent the row to be updated if ARCHIVED=true ? How can i do it ?

Insert True/False Into Boolean Field
When I enter a a true or false value into a boolean field, what is the proper way to enter it? I'm using: INSERT INTO tblTable (IsSomething) VALUES (False) I've heard that a better way is to use 1 and 0, or something.

Can I Insert/Update Large Text Field To Database Without Bulk Insert?
I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.

Update/Insert Date Field, Which Did Not Import From Access
First off, it has been a few years since I have done extensive work with SQL and that was using Oracle. But I am trying to develop a simple asset database for work, as we have nothing in place. I started out with Access, and decided to move to SQL express for many reasons. What I have now is that I imported my data from my access 97 database to Excel, only my AssetTable did not import dates, I assume because Access and Sql Express handle dates differently... so a the time I just ignored that column. Is it possible to insert the dates into the now populated SQL Express database AssetTbl where the AssetID's match? Here is what I have. Sql Express Database Name: BAMS Table Name: AssetTbl fields: AssetID, SerialNum ...(many other fields)... DateAcq <- currently Null Excel file: AssetDateAcq.xls fields: AssetID, DateAcq (in format 07/12/2007) To me it sounds like I need to do a short script/program to loop through the file read an AssetID from the excel file, and the DateAqcuired and then have it do an update on the DateAcq field, but it has been so long since I've done any work with SQL that I am finding there is a lot of "Dust" to blow off, and I don't know if I'm heading down the right track... or completely off course. Thank you.

Trying To Insert Checkbox True/false Into Db
Hi there, I've tried googling this (and looking at the many questions on the forum :) but I've not managed to find a decent tutorial / guide that describes a method for using checkboxs to insert true/false flags in a MS SQL db. The db field i'm setting has type set to "bit", is this correct? And secondly (its been a long day!) I just cant figure out the code to assign the bit 1 or 0 / true or false. This is what I've got so far but it's not working........Function InsertProduct(ByVal prod_code As String, ByVal prod_name As String, ByVal prod_desc As String, ByVal prod_size As String, ByVal prod_price As String, ByVal prod_category As String, ByVal aspnet As Boolean) As Integer Dim connectionString As String = "server='server'; user id='sa'; password='msde'; Database='dbLD'" Dim sqlConnection As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(connectionString) Dim queryString As String = "INSERT INTO [tbl_LdAllProduct] ([prod_code], [prod_name], [prod_desc], [prod_size], [prod_price], [prod_category],[aspnet]) VALUES (@prod_code, @prod_name, @prod_desc, @prod_size, @prod_price, @prod_category, @aspnet)" Dim sqlCommand As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand(queryString, sqlConnection) sqlCommand.Parameters.Add("@prod_code", System.Data.SqlDbType.VarChar).Value = prod_code sqlCommand.Parameters.Add("@prod_name", System.Data.SqlDbType.VarChar).Value = prod_name sqlCommand.Parameters.Add("@prod_desc", System.Data.SqlDbType.VarChar).Value = prod_desc sqlCommand.Parameters.Add("@prod_size", System.Data.SqlDbType.VarChar).Value = prod_size sqlCommand.Parameters.Add("@prod_price", System.Data.SqlDbType.VarChar).Value = prod_price sqlCommand.Parameters.Add("@prod_category", System.Data.SqlDbType.VarChar).Value = prod_category If chkAspnet.Checked = True Then sqlCommand.Parameters.Add("@aspnet","1") Else sqlCommand.Parameters.Add("@aspnet","0") End If Dim rowsAffected As Integer = 0 sqlConnection.Open Try rowsAffected = sqlCommand.ExecuteNonQuery Finally sqlConnection.Close End Try Return rowsAffected End Function Sub SubmitBtn_Click(sender As Object, e As EventArgs) If Page.IsValid then InsertProduct(txtCode.Text, txtName.Text, txtDesc.Text, ddSize.SelectedItem.value, ddPrice.SelectedItem.value, ddCategory.SelectedItem.value, aspnet.value) Response.Redirect("ListAllProducts.aspx") End If End SubAny help would be appreciated or links to tutorials.ThanksBen

Prevent Duplication On UPDATE
Hello I noticed a spelling mistake in the data in a column of several tables, I used the following syntax to alter the spelling: UPDATE [dbo].[Prod_Cat] SET [ProdName]=N'merseyside' WHERE ProdName = 'mmserseyside' The above code correctly updated the spelling error, but it also inserted a new row with the corrected data. So I found myself with two Identical rows containing the corrected information. I had to manually delete the extra row. Because if I had put in a DELETE statement, I would have then lost both rows. What do I need to do to prevent this happening next time. As I find that I need to update the names of some products, but I don't want to duplicate them. Thanks Lynn

Prevent DELETE And/or UPDATE
Hi all!Are there any other way than using rights or Triggers to prevent aDELETE or an UPDATE on a specific column.The "problem" with rights is that they dont apply to all DB-usersThe "problem" with triggers is that they generate lots of extraSQL-codeI would like a solution something like below. If there are anyprimitives like this or other more neat solutions I would be glad toknowCREATE TABLE some_table NO DELETE/* ^^^^^^^^^*/(some_column SOME_TYPE NO UPDATE/* ^^^^^^^^^*/)For clarity, here is a trigger that currently solves the problemCREATE TRIGGER check_updateable_columns ON some_tableFOR UPDATEASIF UPDATE(some_column)RAISERROR(...)GOorCREATE TRIGGER delete_not_allowed ON some_tableINSTEAD OF DELETEASRAISERROR(...)GO

Update Trigger: COLUMNS_UPDATED Evaluates To True For All String Fields
I have a trigger that writes changes to an audit table. In the case of Updates, I only want to write out the fields that have actually changed. My code for COLUMNS_UPDATED evaluates to true for all varchar fields, even when they haven't changed. All other scenarios appear to be working correctly. WHILE @field < @maxfield BEGIN SELECT @field = min(ORDINAL_POSITION) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @TableName AND ORDINAL_POSITION > @field SELECT @bit = (@field - 1 )% 8 + 1 SELECT @bit = power(2,@bit - 1) SELECT @char = ((@field - 1) / 8) + 1 IF ((@TriggerType = 'I') OR (@TriggerType = 'D') OR (@TriggerType = 'U' AND substring (COLUMNS_UPDATED(),@char, 1) & @bit > 0)) BEGIN.......... END END Ideas? Thanks!

How To Restore An Archived Filegroup On Another Server
Hello,I have several archived filegroups that have data in them partitionedbased on the date. These filegroups have been removed from databaseafter archival. For example two months ago. Meantime my productiondatabase is populating everyday.Now I would like to restore one of my old archived filegroups. In orderto do that I would like to backup and restore the current Primaryfilegroup to another server, and also restore the archived filegroupinto that server. The backup commands to backup the archived filegroupand also backing up the primary are:BACKUP DATABASE [DB1]FILEGROUP = 'PRIMARY'TO DISK = 'C:DB1PRIMARY.BAK'WITH INIT , NOUNLOAD , NAME = N'PRIMARY Filegroup backup',NOSKIP , STATS = 10, DESCRIPTION = N'PRIMARY Filegroup backup ofDB1',NOFORMATBACKUP DATABASE [DB1]FILEGROUP = 'DataGroup383'TO DISK = 'C:DB1DataGroup383.BAK'WITH INIT , NOUNLOAD , NAME = N'Filegroup backup',NOSKIP , STATS = 10, DESCRIPTION = N'Filegroup backup of DB1',NOFORMATLater I move the backup files to another server and use these commandsto do the restore on new server:RESTORE DATABASE [DB1]FILEGROUP = 'PRIMARY'FROM DISK = 'C:ArchivalBackupsPRIMARY.BAK'WITH FILE = 1, NORECOVERY,MOVE 'PRIMARY01' to 'C:MSSQLDataDB1PRIMARY01.mdf'RESTORE DATABASE [DB1]FILEGROUP = 'DataGroup383'FROM DISK = 'C:ArchivalBackupsDataGroup383.BAK'WITH FILE = 1, NORECOVERY,MOVE 'DataFile383' to 'C:MSSQLDataDB1DataFile383.ndf'At this point the database can not be used yet and it is on restoremode then I use this command to recover itRESTORE DATABASE [DB1] WITH RECOVERYBut I get an Error:"Server: Msg 4318, Level 16, State 1, Line 1File 'DataFile383' has been rolled forward to LSN 5848000000402600001.This log terminates at LSN 5848000000387700001, which is too early toapply the WITH RECOVERY option. Reissue the RESTORE LOG statement WITHNORECOVERY.Server: Msg 3013, Level 16, State 1, Line 1RESTORE DATABASE is terminating abnormally"I tried several other things as well: backing up the current log andrestore it but it didn't work.Please help or if this is not the right way to do this backup andrestore let me know how to do that. I really appreciate.

Can MsSQL Data File Be Archived And Made Smaller ?
Hi... We have application that connected to MSSQL 2000 database. The database file is getting bigger and bigger over the years. Recently the performance of the database and application is getting slower and slower, my senior oracle DBA told me that I should archive the MSSQL 2000 data file and export the old record to the archive DB. So that the number of record will be less and it will be faster. I would like to know whether MSSQL 2000 support archiving of the database file ? If yes, what is the way to do it ? I could not find it in Enterprise manager option at all.

Single Complex INSERT Or INSERT Plus UPDATE
Hello,I am writing a stored procedure that will take data from severaldifferent tables and will combine the data into a single table for ourdata warehouse. It is mostly pretty straightforward stuff, but there isone issue that I am not sure how to handle.The resulting table has a column that is an ugly concatenation fromseveral columns in the source. I didn't design this and I can't huntdown and kill the person who did, so that option is out. Here is asimplified version of what I'm trying to do:CREATE TABLE Source (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,ssn CHAR(9) NOT NULL )GOALTER TABLE SourceADD CONSTRAINT PK_SourcePRIMARY KEY CLUSTERED (grp_id, mbr_id)GOCREATE TABLE Destination (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,member_ssn CHAR(9) NOT NULL,subscriber_ssn CHAR(9) NOT NULL )GOALTER TABLE DestinationADD CONSTRAINT PK_DestinationPRIMARY KEY CLUSTERED (grp_id, mbr_id)GOThe member_ssn is the ssn for the row being imported. Each member alsohas a subscriber (think of it as a parent-child kind of relationship)where the first 9 characters of the mbr_id (as a zero-padded string)match and the last two are "00". For example, given the followingmbr_id values:1234567890012345678901123456789021111111110022222222200They would have the following subscribers:mbr_id subscriber mbr_id12345678900 1234567890012345678901 1234567890012345678902 1234567890011111111100 1111111110022222222200 22222222200So, for the subscriber_ssn I need to find the subscriber using theabove rule and fill in that ssn.I have a couple of ideas on how I might do this, but I'm wondering ifanyone has tackled a similar situation and how you solved it.The current system does an insert with an additional column for thesubscriber mbr_id then it updates the table using that column to joinback to the source. I could also join the source to itself in the firstplace to fill it in without the extra update, but I'm not sure if theextra complexity of the insert statement would offset any gains fromputting it all into one statement. I plan to test that on Monday.Thanks for any ideas that you might have.-Tom.

Get The Field Value After INSERT
Hi,Problem:I need to get the value of auto-incremented field from just insertedrecordIn Oracle this is INSERT .. RETURNING command.In SQL Server there are @@IDENTITY, IDENT_CURRENT, SCOPE_IDENTITY- @@IDENTITY returns the value from the very LAST insert on any tableinvolving in the insert process ( including triggers ) ,so this value may have nothing to do with my table- IDENT_CURRENT returns the last identity value generated for aspecific table in any session and any scope,so this value may come not from my session- SCOPE_IDENTITY returns the last identity value generated for anytable in the current session and the current scope , but from the veryLAST insert command ( that may be some INSERT in the audit tables)so it may have nothing to do with my tableQuestion :- Is there any trusted way I can get the value of auto-incrementedfieldin my table and in the scope of my session?Thanks, Eugene

How To Update Text Field
Hi all, I have a table with millions of records, table has three fields: case_id,line_no and notedata field, notedata field is 60 chars long, datatype varchar.for each case_id there could be as many as 2000 line_no meaning 2000 notes. I need to compress these notes into one note by case_no, For example case_no 1 could have 2000 lines of notes but my comressed table shoul have only one line containing all 2000 notes in line_no sequence. my compressed table contains two fields case_no and notetext, notetext is a text field. here is the script I am trying to use to accomplish the task but it does not append more than 8000 chars in one case, so my notes are chopping of, how should I do this, please let me know of any suggestions..

Update A Decimal Field To 0
Hello, I am updating three fields (defined as decimal(18,4) NULL) in a 1.7 million record table to 0. This table is also very wide (meaning lot of columns). A simple query like this - Update Table1 Set [Decimal Field1] = 0, [Decimal Field2] = 0, [Decimal Field3] = 0 is taking forever (1+ hours) to run. Either I may be doing something stupid here or I am missing something vital. Thanks for any help.

Hi, I'm trying to use the Update command to change a field value. I only know the field name at run-time, how do you write this command. This is what I have done which just sets the variable @cFieldName to the value and not the field within the table. UPDATE [Atable] SET @cFieldName = @aValue WHERE ([Id] = @Id_1) Thanks
