Reset Database Files From Read-only To Read-write
Jan 18, 2008I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:
Server: Msg 3415, Level 16, State 2, Line 1
Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?
thanks

View 2 Replies View RelatedConcurrency Issue On A Single Database User For An Online Read/write Application
Aug 3, 2006Hi to all DBAs,
I would like to ask if there will be a write and concurrency issue if i would create an online application with just one user connecting to the database, just like most open source php/mysql that can be downloaded
i.e
Setup 1. I will grant a single user that will connect to a database and will be set to a config.inc.php file and then create a table users (userid, username, password) and this table will be used for the application authentication and access control.
Setup 2. or is it much better to grant users that will connect to the database and have the table users for access control of the application?
to further illustrate my query:
Setup 1 would be:
###################Table: Users
user a@ipadd --> db1 --> userid mary --> myOnlineApp
user a@ipadd --> db1 --> userid john --> myOnlineApp
user a@ipadd --> db1 --> userid paul --> myOnlineApp
and Setup 2 would be:
#####################Table: Users
user mary@ipadd --> db1 --> userid mary --> myOnlineApp
user john@ipadd --> db1 --> userid john --> myOnlineApp
user paul@ipadd --> db1 --> userid paul --> myOnlineApp
will Setup 1 be enough if I will use SQL Server as database?
or Setup 2 is better user/database architecture?
This application will be online enrollment for a school with 16,000 students
very much appreciated for the feedbacks and suggestions

SQL 2012 :: Read Committed For Read Only Database?
Jun 27, 2014i have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?
SQL Security :: Making Data Change In Read Only Database Without Letting Other Users Update Data
Aug 6, 2015I want to make data changes in read_only database , that's why i must set database read_write. While database is at read_write mode, i want to be sure that no one makes change in database.
For this aim, i write the code below, but i suspect that after setting the database read_write, till the setting database
single_user ,is it possible get DML script from another user. Is the code below enough for this operation. Or is there another way?
Reminding: Read_only database can not be set single_user mode. That's why, first you must set database read_write.
The code;
use master
alter database xxx set read_write
with rollback immediate
alter database xxx set single_user
with rollback immediate
use xxx
update tablexxx set columnxxx=yyy
use master
alter database xxx set read_only
with rollback immediate
alter database xxx set multi_user
with rollback immediate

a. Read data from Different CSV files.

View 1 Replies View RelatedSQL Server Admin 2014 :: Calculating Average Read / Write Latency Across Instance Using Counters
Apr 27, 2015How you would calculate the average read/write latency experienced by a SQL Server instance during a specific time window in order to monitor this for multiple instances. From this MSDN blog, I know that you have to take multiple samples and do some calculations to get the correct latency.
[URL] ...
However, the SQLServer:Resource Pool Stats object tracks these numbers per resource pool and we want to get one number for the whole server. Since there can be a different base value for each resource pool, you can't simply sum the numerator values together. Here's some sample data from a server that illustrates the problem.
object_name counter_name instance_name cntr_value cntr_type
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) default 307318919 1073874176
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base default 25546724 1073939712
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) internal 2045730 1073874176
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base internal 208270 1073939712
I'm thinking I would need to do some sort of weighted average, but I'm not sure if that will result in the correct value. Here's the formula I am thinking about using currently before doing the calculation over time
((default * default[base]) + (internal * internal[base]))/(default[base] + internal[base])
Then to do the calculation over time, I'd use the changes in the calculated numerator and denominator to get the average.
Does this sound like to correct way to get this value? Is there a good way to verify?

Batch File - Read From One Table And Write To Another Database And Table
Nov 17, 2011Any 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

Read/Write Performance
Apr 21, 2006Hello,
We currently run sql 2005 server and also sql express in our dev environments. We use sql express as an offline store (smart client). We have a similar/exact schema on the sql 2005 server and also the express.
We use the auto attach feature to connect to the express version of the database. Both the developer machines and the one that is running the sql 2005 server have exactly the same hardware configuration. The only difference may be that the server box is not running the VS.Net environment. The disk space etc is pretty much the same. Actually we run another database server(DB2) on the 2005 server machine.
We have observed that sql express is much slower and queries execute much slower aswell. For example, this may not be a totally scientific way of checking but a long running query on the server took only 2 minutes while on express it took longer than 9 minutes. The schema and data etc are the same.
Is there something we need to look into as far as read write speed/performance goes ?
TIA,
Avinash

Read And Write A Constraint Or Default Value
Nov 20, 2007Okay, maybe I'm getting ahead of myself.
Using SQL Server Express, VWD and .net 2.0 I've figured out how to drop a Table Column Constraint or Default Value/Binding and then Create it again using a stored procedure. What I can't figure out is how to retrieve that column's constraint value and write it to, say a label, in an aspx page, simply for reference. Is it possible? In this case the Data Type of the column is money.
I'm using it to perform a calculation to a column with a value that the user inserts into another column. (Column1(user input) minus Column2(with Default Value) = Column3(Difference). I just want to read Column2's Default Value for reference so I know whether to change it or not.

Use Variables As A Storage [read/write] ?
Aug 2, 2007Hello Guys,
in SSIS I want to get a set of data and do some modifications on it before I insert it into the destinatipn. So far so good. Some of the modifications will include comparisions between two columns and if certain field is NULL then I want to get the value from the other one I was comparing to. When using conditional splits, I only get the rows to be redirected so that I can do whatever next. However, I want like use the variables as a storage so that I can put the value of one of the two columns in this variable which will be actually loaded into the destination finally. Any help?
Thanks
