Use Database Statement In Script
Nov 24, 1998
I'm having a problem getting the database name to substitute properly in the
USE database statement when used in a SQL script. Essentially, I have a
variable defined as follows:
declare @databasename varchar(30)
use @databasename
After the variable is initialized with a database name, the USE statement
does not substitute the correct value, instead it uses 30, the length of its
description in the 'declare' statement. Any ideas to force a correct value
substitution?

I'm having a problem with the following script:
use master
declare database_cursor CURSOR for
SELECT name from sysdatabases
OPEN database_cursor
DECLARE @databasename varchar (30)
FETCH next from database_cursor into @databasename
while (@@fetch_status <> -1)
BEGIN
use @databasename
exec sp_spaceused
FETCH next from database_cursor into @databasename
END
The substitution of database name in the USE statement does not work correctly. It substitutes in the length, '30', from the declare variable statement. I've had one suggestion to try declaring the variable as DECLARE @DATABASENAME SYSNAME but that has not worked. Any ideas?

Hi All,
I have watched one of the video tutorials under SQL Server section called "Connecting your web application to SQL server 2005 express edition" (number 8).
It was about creating a database with single table and then updating it by inserting new records in a text box an clicking on submit button. In code section there is a sql insert statement and connection string is via configurationManager (name of the connection string is taken from web.config and is spelled properly)
Anyway, my problem is that updating that database by filling the textbox and clicking submit button is not working.
I have no error message (nothing happens) - database is not updated.
If I add to the page a data grid view with updating and inserting selected then it all works. I was trying to use debbuging with break point setup but couldn't find any errors.I have done everything the same way as on the video.... I am beginner in C# so your help will be much appreciated.
Here is the code:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;public partial class _Default : System.Web.UI.Page
{protected void Page_Load(object sender, EventArgs e)
{
}protected void Submitbutton_Click(object sender, EventArgs e)
{
SqlDataSource dashDataSource = new SqlDataSource();dashDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["dashConnectionString1"].ToString();
dashDataSource.InsertCommandType = SqlDataSourceCommandType.Text;dashDataSource.InsertCommand = "INSERT INTO Email(EmailAddress, IPAddress, DateTimeStamp) VALUES (@EmailAddress, @IPAddress, @DateTimeStamp)";
dashDataSource.InsertParameters.Add("EmailAddress", EmailAddressTextBox.Text);dashDataSource.InsertParameters.Add("IPAddress", Request.UserHostAddress.ToString());
dashDataSource.InsertParameters.Add("DateTimeStamp", DateTime.Now.ToString());int rowsaffected = 0;
try
{
rowsaffected = dashDataSource.Insert();
}catch (Exception ex)
{Server.Transfer("Newsletter_problem.aspx");
}
finally
{dashDataSource = null;
}if (rowsaffected != 1)
{Server.Transfer("Newsletter_problem.aspx");
}
else
{Server.Transfer("Newsletter_confirm.aspx");
}
}
}

Hello,I hope you can help me.We have a SQL Server 2000 database at work, (which works with a VB6frontend) which grew to a considerable size, so one of my past colleaguessent me this truncate statement to use on the database.I ran it like this, and all appeared to be well, it shrank the database,Shortly afterwards, after I ran this I noticed something not quite right.for example, one of the tables we keep is a User_Admin table which has 50records in there, when I accessed this using the frontend it only showed 1record, and this happened with every table in the database accessed by thefrontend.The data in the tables is still there, but only shows one record through thefrontend.Can anyone help me, and check this statement I ran, as its weird that allthis happened after I ran this statement.Thanks,Jayne Hegersp_dboption PBTDEV,'trunc. log on chkpt.', truecheckpoint--sp_dboption sadev,'trunc. log on chkpt.', falsesp_dboption PBTDEV,'autoshrink', true--sp_dboption sadev,'autoshrink', falseDBCC SHRINKDATABASE (PBTDEV, NOTRUNCATE)

I have following SQL statement which I run on an Access database. ( Program written in VB.NET )
'---------
SELECT c.*
FROM Communications AS c
WHERE CommDate Between #1/4/2005# And #5/4/2005#;
'------------
I've put dummy values in the database for dates between 1st and 8th of april... And running this query suprisingly gives back ALL rows in the table... Also the entries for the 6th, 7th and 8th of april... In fact it just gives back the WHOLE table, no matter which values I add...
If I use '1/4/2005' (not with #) then I get an error back.
Anybody an Idea how to make a BETWEEN statement work in an access database?
Thanks,
Frederik

Hi everyone,
I have been trying to perform the following task:
Using the sys.databases & sys.sysindexes views to display all the columns with a clustered index for all tables and all databases in a given server. So the end result will have 3 columns:
Database name
Table name
Column name from that table with a clustered index
I have already created the following script which displays all the databases for a given server:
declare @DBname nvarchar(128)
declare testCursorForDB cursor
for
select name from sys.databases with (nolock)
where name not in ('master','tempdb','model','msdb')
order by name
open testCursorForDB
fetch next from testCursorForDB
into @DBname
while @@fetch_status = 0
begin
print @DBname
fetch next from testCursorForDB
into @DBname
end
close testCursorForDB
deallocate testCursorForDB
I also have created the following query which will display all the table and column names which have a clustered index for a given database:
select object_name(i.id) as TableName,
i.name as IndexName
from sys.sysindexes as i with (nolock)
where i.indid = '1'
However, what I need help/advice on is how do I combine these two together into one working script (either using nested cursors or a better way). In other words, how can I specify which database to use (ie. using the "use database_name") so that my query above will be applied to each database found within the cursor.
Any help is greatly appreciated
Thanks!

Hi,
I have a problem with CREATE DATABASE statement, since it needs to specify the absolut path for a file in the FILENAME= option. I would need instead a relative path, i.e. only the name of the file because the script that launch this SQL command is dependant on the installation path decided by the user, during the installation.
Is there a way to pass to the FILENAME only the name of the file?
Hope to have been clear :-)
Thanks in advance

Good day,
I have seen in Enterprise manager there is a toll that can script the all tables in a database, but nothing that can generate the insert statements for all the rows in each table in a secified database.
Does any one know of a application, plug in, script that can generate the insert statments for all the tables in a database?
Please someone help, this is driving me insane.
Thanks

Recently I created a DDL Server-scope trigger using the following:
create trigger stop_alter_database on all server
for ALTER_DATABASE
as
rollback;
print 'database change stopped by stop_alter_database';
go
Then I ran the following script:
alter database [test] modify file (name=test', maxsize=2028mb);
The result was:
Msg 3609, Level 16, State 2, Line 1
The transaction ended in the trigger. The batch has been aborted.
database change stopped by stop_alter_database
The problem is that when I checked the max size of the data file it had changed. So, the statement was never rolled back. Is there something I'm missing because I can't find any documentation or articles that state the inability to rollback alter database statements. Whats going on?

Hi,
I have a select statement running on the client machine linking to different tables in 1 database. All with the same schema. When I ran it, i had this error. I had trial and error, removing 1 table at a time until i hit the one which is causing it. when i removed it, everything's ok. i just wonder if all the tables were using dbo schema what is causing this particular table to throw this error?

question 1:
i found that database log file can contain more records after performing backup database statement.
for example:
i create a database and limit the log file to 2mb. then i create a table and insert data.
If i backup the database before i insert data , the database file can contain 192 records unitl the log file is full.
If i don't perform the 'backup database' statement.
The 'dbcc sqlperf(logspace)' indicate the utilization ratio is less than 40% after inserting 192 records
why?
I list my code:
Code Snippet
create database db_test
on primary
(
name=db_test,
filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test.mdf'
)
log on
(
name=db_test_log,
filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test_log.ldf',
maxsize=2mb
)
go
backup database db_test to disk='db_test.bak' --- if i don't execute this line, log file can contain a lot of record
go
create table db_test..table1(col char(8000))
--insert data to fill up the database log
declare @n int
set @n=0
while @n<192
begin
insert into db_test..table1 values(replicate('a',8000))
set @n=@n+1
end
question 2:
i create a database and limit the log file to 2mb. Then i create a table and insert data in an endless loop.
After the inserting operation executing for a while, the 9002 error occurs, indicate the log file for the database is full.
But the 'dbcc sqlperf(logspace)' command indicate the unilization ratio is low, and log_reuse_wait_desc in sys.database is 'CHECKPOINT'
And I can insert data , and i'm sure the state of log_use_wait_desc is 'CHECKPOINT'.
As i known, the checkpoint can't truncate log under full recovery model. Only the back log operation can truncate the transaction log.
So log is not full, why 9002 error is encounterd. and why the log_reuse_wait_desc return 'CHECKPOINT'?
I list my code:
Code Snippet
create database db_test
on primary
(
name=db_test,
filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test.mdf'
)
log on
(
name=db_test_log,
filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test_log.ldf',
maxsize=2mb
)
go
create table db_test..table1(col char(8000))
--insert data to fill up the database log
declare @n int
set @n=0
while @n<>-1
begin
insert into db_test..table1 values(replicate('a',8000))
end
any suggestions?
thanks in advance.

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:

I am using ASP.NET 2.0, and am attempting to write some code to connect to the database and query a data table. The compiler is not recognizing my SqlConnection statement. It does recognize other commands. And just to make sure, I created other sql objects such as ObjectDataSource and SqlDataSource. The compiler does not find a problem with that code.
Basically the compiler is telling me that I am missing a "using" directive. The compiler is wrong though, because I am including the statement "usingSystemData" Can someone please take a look at my code below and to see if you notice what the problem might be? Note that I numbered the lines of code below. Note that I also tried putting lines 3 trhough 6 before line 2(The page directive) but that did not fix the problem The compiler still gives me the same compiler message.

Hi All,
I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance.
My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.
Here is my code:
Insert into myTblA
(TblA_ID,
mycasefield =
case
when mycasefield = 1 then 99861
when mycasefield = 2 then 99862
when mycasefield = 3 then 99863
when mycasefield = 4 then 99864
when mycasefield = 5 then 99865
when mycasefield = 6 then 99866
when mycasefield = 7 then 99867
when mycasefield = 8 then 99868
when mycasefield = 9 then 99855
when mycasefield = 10 then 99839
end,
alt_min,
alt_max,
longitude,
latitude
(
Select MTB.LocationID
MTB.model_ID
MTB.elevation, --alt min
null, --alt max
MTB.longitude, --longitude
MTB.latitude --latitude
from MyTblB MTB
);
The error I'm getting is:
Incorrect syntax near '='.
I have tried various versions of the case statement based on examples I have found but nothing works.
I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.
