Is it possible to make a table (or set of tables) within a SQL Server database read only (still granting the db_datawriter fixed database role to database users) without dropping and recreating the db_datawriter database role?
View 1 RepliesHow would I find the last read/write dates for all the tables within a database.
View 6 Replies View RelatedI have a requirement to read a value from table and increment it by 1. There can be multi-threads doing the same operation and would need a ROW LOCK so that read and write both are atomic. How can i put an exclusive lock on the row before I read the value from the table.
CREATE TABLE [dbo].[tblOnboardingSequence](
[OnboardingSequenceID] [uniqueidentifier] NOT NULL,
[Name] [nvarchar](255) NOT NULL,
[NextNumber] [bigint] NOT NULL,
CONSTRAINT [PK_OnboardingSequence] PRIMARY KEY CLUSTERED(
[OnboardingSequenceID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
My Stored Procedure has below logic
DECLARE @NextNumber BIGINT
----------- Acquire row lock here
SELECT @NextNumber = NextNumber FROM tblOnboardingSequence WHERE Name = 'TPO'
UPDATE tblOnboardingSequence SET NextNumber = @NextNumber + 1 WHERE Name = 'TPO'
----------- Release row lock here
I would like to have a row lock for the row having Name "TPO" before SELECT query and release after UPDATE query.
What si the best way to deal with this?

View 1 Replies View RelatedI am setting up extended events more or less just fine, however I am a bit confused as to how to read and load them into a table for querying. In particular the offset part - is there a way to load just a given dates worth in?
I've got the files configured to be 20MB before rolling over, the XE is running all the time.
So if i load in the full file now, say that covers 2.5 days worth, when I load it again tomorrow to get the updated data I'm also reloading today, which is a waste?
I presume I am going about this wrong, but lack an example that really goes into detail of practicalities of loading this data.
Any easy way for a batch file or automated process to read from one db and table and what ever entry is missing out of another database + table it writes those missing entries to.
This is a simple table in one db that is filled with usernames, I want to see if there are missing usernames in another db and table and write those entries.
db1.usr_table.usr_name = jdoenew
If jdoenew is missing in the 2nd db I will need to write entries like:
db1.usr_table.usr_name = jdoenew
db1.usr_table.password = tmppassword
db1.usr_table.active = 1
Here is My requirement, I'm not sure if this is possible. Creating table called master like col1, col2 col3, col4 , col5 ...Where Col1, col2 are updatable - this can be done easily
Col3, col4 are columns in another table but these can be just a read only ?? Is this possible ? this is possible with View but not friendly with share point CRUD...Col 5 is a computed column of col 2 and col5 ? if above step can be done then sure this can be done I guess.
Hey ,
I have sql server 2000, and i am using Microsoft Application block.
I have Transaction Like...
SqlConnection conn = new SqlConnection(ASLConnectionString); conn.Open(); SqlTransaction Trans = conn.BeginTransaction(IsolationLevel.ReadUncommitted);
But If i have another process that try to read the Table if that old transaction running.. it wouldn't Allow me to read the DATA.
i tried Isolation level "snapshot" but that works under sql server 2005 only. so i can not use that. And i have some services that will run during day time.
So if anybody have solution to read the data from table...from sql server 2000 even if another transaction is running?
Please Give any guideline..Help will be appriciated.
thanks & regards,

i want read table name in database in sql while loop statement
I work on an MS Access project ( *.apd - file) that is linked with a
SQL-express server 2005 (local installed). On this server are 2 databases x
and y.
I linked some tables of database x to y and here's the problem: the linked
tables are read-only.
My authentication for the server is Windows authentication and I'm
administrator.
I say this because I think the problem is a security problem.
when I try to change data in the
linked table in Microsoft SQL Server Management Studio Express, I get now the follow error:
---------------------------
No row was updated.
The data in row 12 was not committed
Error source: .Net SqlClient Data provider.
Error Message: Transaction context in use by another session.
Correct the errors an retry or press ESC to cancel the change(s).
---------------------------------
All other programs are close, except MSE
thanks a lot!!!!!
Can somebody help me to make the linked tables are not read-only? What is
the problem, what did I wrong?
Thanks a lot!
Hi!
I have a table like this below and it doesn't only contain English Names but it also contain Chinese Name.
CREATE TABLE Names
(FirstName NVARCHAR (50),
LastName NVARCHAR (50));
I tried to view the column using SQL Query Analyzer, It didn't display Chinese Character.
I know that SQL Server 2005 is using UCS-2 Encoding and Chinese Character uses Double Byte Character Set (DBCS) Encoding.
I want to read the FirstName and LastName columns and display in Window Form Data Grid and ASP.NET Grid View.
I tried to use this code below and it didn't work. It convert some of the English Name to Chinese Character and it display the chinese character and some still in the original unreadable characters.
Does anybody know how to read those character from SQL Table and display the correct Chinese Character without converting the English Name into Chinese also?
Thanks

Hello
I'm working on a package which loops through each xml file in a folder.
The name of each xml file is put in variable.
The format of the filename is something like "part1_part2_part3.xml"
I need to store the 3 parts in three different columns of table A
The content of the xml file needs to be manipulated ("." needs to be replaced with ",", ....)and put in serveral columns in tableB
It's not clear to me yet how to start this but my main concern is read the three parts of the filename. I don't find any task in SSIS which could help me with that.
Could someone give me some pointers?
Many thanks!

Hi,
My Issue is that, I have to create a package which should read from multiple table from a RDBMS Source.
Right now I have different Source adapters for each table. I want to reduce the number of source adapters.
Can I
1) Create a connection manager and set the connection string from a variable. Set the variable from a script task. Put both of these into for loop container (no of tables).
Issues
a) Most of the table has same schema, but few have different, so all tables which has same schema will work.
For different schema anyway I have to create different data source.
b) Will Destination column mapping work.
If any one has already worked on it let me know.
Thanks

Is there a way to get the last read/write time of a table?
I want to have a few tables, but only allow them to exist if they have been used in the last 30 days. I want to set up a "purge" job to clear out any tables that have not been used in 30 days.
Declare @cmd varchar(255)
select @cmd = 'bcp "select * from mytable" queryout c:cptest.txt -Uasdfasdfasdf -Pasdfasdf'
when i run this it says "The command(s) completed successfully." but i don't see that file anywhere at all. why is that? is this the right way to do? please help.
The problem that I am having is that I am not getting the results from an entire table, just a small subset. The sql command is "Select * from login", which has always implied to me, get everything, to end of table, or, until I tell you to stop. I am getting exactly, 10 items as input, and then it stops. I am including the code below in the hopes that someone can spot what it is that I am doing wrong.
The purpose of the routine is to convert a user login database into a new, expanded format.
TIA, Tom

In a stored procedure, I am trying to create a table and then read it from within that SP or from another one (nestsed). When I run the below code (simplified version of my real SP), no records are returned even though I know that there is data. The table is created and records are inserted, I just cannot read the records from the SP or one that calls it with an EXEC.
Any ideas? My code is listed below. (When I get this to work, I plan to convert the code to manipulate a temporaty table).

I am using sql server 2000 to perform address cleansing. there is a point in my scripting when a table i pass values to becomes read/write.
i suspect this is when i run a cursor through the table.
Is anyone able to confirm for me whether running a cursor changes a table's properties?
Many thanks.

Ps as the table seems to be read/write it is harder to tell if NULLs are in the table and this is messing with joins I have further down the track.
I am quite new to MS SQL, and I want to read rows from a todo table, andwhen a row has been processed, I want to delete that row.Ages ago in MySQL I would probably have locked the table, select, processa row, delete a row, unlock the table.I have been reading through the documentation from MS SQL, but it's notclear what exactly I should do.Since I want to lock only one table in the select (the others just providedata, and are not modified), what's a good solution?--John MexIT: http://johnbokma.com/mexit/personal page: http://johnbokma.com/Experienced programmer available: http://castleamber.com/Happy Customers: http://castleamber.com/testimonials.html
View 2 Replies View RelatedI have a data file that I converted from Access to SQL Server using theupsizing wizard. I then attached the tables to the Access front end using anODBC connection. I have one table that is read only for some reason. I'mnot sure how that happened, it went through the same procedures as the othertables in terms of upsizing and connecting. The original table was not readonly or hidden or anything else, it had full permissions.I've tried disconnecting and reconnecting the table but still the samething. In SQL Server, the permissions are the same as all the other tables.I can't seem to figure out what's making this one read only.I'm using SQL Server 2005 Express and Access 2003.

As far as i know all users that is assigned to "Public" database role by default cannot SELECT any tables which in the databases. But in my case i am restoring database from previous version of SQL Server 2005 to SQL Server 2008 R2.
The problem come when every new users that created can access all tables in the databases.
How to get "public" back to default permission settings?
