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 ?
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.
If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName)
VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
SELECT FirstName, LastName, NULL
FROM MYOTHERTABLE
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.
View 6 Replies View RelatedFirst 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.
I want to update a field and in this field insert a increment count, for example:
When I make, "Select * from Users order by User" displays:
User1 | NULL
User1 | NULL
User1 | NULL
User2 | NULL
User2 | NULL
and I want to do this:
User1 | 1
User1 | 2
User1 | 3
User2 | 1
User2 | 2
how to do this?
I want to create a trigger that, when a field is updated or a record is inserted, counts the number of words in "field1", inserting this numeric value into another field in the same table. What would be the most efficient, fastest method for doing this?

When calling the RS SOAP API's CreateReport method, it doesn't seem like the report description is updated, unless I first delete the report and then recreate it.
Here's what my call looks like -
Warning[] warnings = rs.CreateReport(reportName, "/" + folder, true, buffer, null);
Is this a known issue?
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
Is it possible to create a trigger to prevent update of a row if no signifiant colums are updated
Example : I need to allow the update only if colums a,b or c have changes ?
how it should works to keep or discard the update according to condition ?
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

I'm trying to find a way to maintain the data that was UPDATEd in a table from being overwritten.
I used UPDATE in a table to include missing data. However, since I do not have access to the original table from where the data is derived, when I run my query, it knocks out the data in my table that was updated, because it is linked to the orginal table that has the blank fields. A few users do not have an employee email, and this has to be updated with a personal email account for now.
My update works fine, but is there a way I can use the statement in my query so that it updates each time it is run to maintain the user email address? This will solve the problem of not having to change the original table that I do not have access to.
if exists (select * test..dbo.Employee)
truncate TABLE
test.. dbo.Employee
insert into test.. dbo.Employee (EmployeeNumber
, EmplUsername

The number of files to retain for SQL Server Logs is set to 99. When I expand the SQL Server Logs node in SQL Server Mgt Studio it shows the current log file through Archive#49. The oldest archive file is dated 2015/05/26. If I select that archive in SQL Server Mgt Studio it shows me the details and entries of that archive file. Yet when I go to the directory on SQL Server for the log files there are only the 5 most recent files. I have searched for '.trc' files on the entire drive and have found no other files.
How can SQL Server Mgt Studio show archive files that have no corresponding archive file in the directory that is supposed to contain the log files?

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.

I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.

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.
