My First ASP.NET (simple) Search Page For SQL

Mar 30, 2005

This question probably applies to Visual Web Developer but I don't know if it belongs in this Forum or that, sorry if you have to move it.
Hi there kind person reading this
I've created a stored procedure in SQL2000 that selects records where (name = @name) AND (site = @site). It works as I have tested it with Enterprise Manager.
I have also created a page with VWD that has a drop-down list populated with the site records and a text box. I have put an SQL data source on the page that is configured to select from the stored procedure. However, I can't set the @name and @site variables to collect from the ddl and txtbox through the wizard! I've tried selecting a Control as the source for @site but neither the ddl or txtbox appear in the control dropdown list. So  I want to crack it with handwritten code.
Does anyone know of a post or article that can help me link the ddl and txtbox to a search button, which calls the stored procedure with the chosen variables allowing me to put the returned data into a gridview? I've been through a great walkthrough for VWD (Student Activities) but it doesn't seem to apply to the latest version - or there's something wrong with my (seems fine though) instalation. Thanks if you can help, I owe you a

Simple SQL Update

Mar 16, 2004

Hello all and I look forward to reading your replys. Currently, I'm trying to update a table in my SQL database by writing a script that will go get the field name and correct info, verify it has the correct field by using two other columns and then update the information.

I do not know how to use tell SQL what to update when the field name can change. I've used the following in the past.

UPDATE [Import Table]

SET [Import Table].[???] = [Correction_Table].[Correct_Info]

WHERE [Import Table].[UNIQUE ID] in (select [USO Unique ID] from [Correction_Table])

IN this new instance, I'm reading the Field_Name from the Correction_Table so I don't know what to put in my SET statement.

Please any help or pointers in the right direction would be greatly appreciated.

Simple UPDATE

Feb 26, 2008

I need to do an update. Can you tell me if it's possible to update multiple tables in a single statement when joined, as with a select, or this has to be taken care of in seperate statements with the same join? I'm sure this is a simple YES / NO answer.

Here is what I'm using, with the same structure as somewhere else... why do I get 'incorrect syntax near q' on that very first line?

-- Do the update
update ccs_quotes q
set ccs_quo_user_date#1 = j.completed
from "ken-sql-002".hettonhosttestdatabase.dbo.job j
inner join ccs_quotes q
on left(j.cid,10) = q.ccs_quo_ref_number#2
where completed is not null
and ccs_quo_ref_number#2 = 'SHGD40021'


Thanks a lot

Simple Db Update Question

Oct 4, 2007

Hi folks. I'm trying to update a single field in a database table with the input from a single text box, but I'm getting "Insert Error: Column name or number of supplied values does not match table definition". I know at least part of the problem is that I haven't specified the name of the table field, but I'm not sure where to do this. The table in question has many fields, but I only want to update one. The submit button is "sendMail", which calls UpdateDB.I'm learning and trying to limit myself to 1 idiotic question per week. Please have mercy. Thanks. Chrisprivate void UpdateDB(string cmd)
{
// point to connection string in web.config
string connectionString = "Data Source=localhost;Initial Catalog=databaseName;Integrated Security=True";
// create connection object; initialize; open
System.Data.SqlClient.SqlConnection connection = new System.Data.SqlClient.SqlConnection(connectionString);
try
{
connection.Open();
// create sqlcommand object and assign connection
System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand();
command.Connection = connection;
command.CommandText = cmd;

Simple (?) SQL 7.0 Update Taking Forever...

May 3, 2000

I have a simple update/initialization query (set integer column = 0 on all rows) that's been running for over 28 hours. There are just over 27 million rows in the table. In current activity it shows that the transaction is open but it's sleeping, and in locks it shows 1 DB S mode lock, 766 page X mode locks, 1 page U mode lock, and one table X mode lock. Server is 7.0 with 1.7 gig ram. Anyone have any ideas as to why it's taking so long? Table is about 7 gig in size; can't get to it in Enterprise Manager without locking it up...

Simple SQL To Update Specific Columns

Kairn writes "I have created a table and imported data from another table to it. I need to update the existing data with values from another import but only need specific columns and am assuming a stored procedure is the way to go...IF I create a source table as well as destination(?). I have to compare the value in 6 columns to find the matching record in the destination, then update 5 of the other columns where source=dest. Finally, I need to sum, by row, the value in 3 of the columns and update another column to reflect it. All rows are unique in the destination. The source is a duplicate of them.

How To Avoid Deadlock With Simple Update Statements

Aug 29, 2007

I searched a bit but didn€™t get too far in actually solving a case of deadlock in a simple query I have running here. The queries in question are executed under 2 separate transactions (Serializable IsolationLevel) and are shown below. I guess I don€™t understand how those 2 can deadlock because they are operating on different rows of the table and Serializable should keep them isolated pretty well too. Is it because I€™m using the column value inside an update stmt? How should this query be split if that€™s the case?

This is what the SQL Profiler has to say:
Lock: Deadlock Chain Deadlock Chain SPID = 59
Lock: Deadlock Chain Deadlock Chain SPID = 57
Lock: Deadlock my_user_name

57: UPDATE CreditCard SET Balance = Balance - 200 WHERE (Account = 0 AND CardHolder = 'Foo' AND Balance - 200 >= 0)
59: UPDATE CreditCard SET Balance = Balance - 250 WHERE (Account = 3 AND CardHolder = 'Bar' AND Balance - 250 >= 0)

I also used DBCC TRACEON(1204, 3605, -1) but I don€™t understand what the SQL log is telling me. Can anyone shed some light on why the above 2 statements sometimes cause the following:
System.Data.SqlClient.SqlException: Transaction (Process ID 57) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)
at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)
at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj)
at System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds(String methodName, Boolean async)
at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe)
at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()

I really don't want to retry the update if I don't have to. Table looks like:
Column DataType Length

Account int 4
CardHolder char 64
Balance float 8

Unable To Update A Table From A Web Page.

Jan 18, 2008

In my web page(.Net/c#) , I  want to update few fields of a database table. The code is fine. The stored procedure through which I perform the execution is fine. I'm confidently saying this is because, if I try to do the update direclty while executing the stored procedure, it gets updated. I'm facing a weird problem while trying to update the fields from my web page. When I make an update and submit it, the first time it shows the updated value in the screen. But if I try to refresh it or redisplay the data ( I guess whenever it makes a trip to the database), the old values gets populated instead of the new values. I tried debugging it, but everything seems to be working fine. I looked up the execution in SQL Profiler, everything seems to be fine. I've no clue what's going on. I've proper  permissions to make an update. So there is no permission issue. Could someone tell me how to handle this issue and what might be the possible problem which makes the values not update in the database?

A Simple Update Query Using A Date - Conversion From Msaccess

I'm converting an ASP system from using msaccess to SQL Server as the db engine, and I'm stumped on the following query

TcdDate = #3/18/05#


TcdDate is defined as a date/time type

It will not run with the date bracketed by # signs, and when I take them out, 1/1/1900 is stored in the dbs. Is there a different symbol to bracket the date with or should I be using a function to convert the date?

Msg 1105, Level 17, State 2, Line 8
Could not allocate space for object 'dbo.Large Object Storage System object: 440701391536128' in database 'tempdb' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.

T_PERF_LOC has 30,000,000 rows and T_MASTER_LOC has 2,000,000 rows
There is and index on V_KEY in both tables. CHANNEL_KEY is of Integer datatype and not indexed.
F_MAP function performs simple lookup on very small table (10 rows)

UPDATE A
SET CHANNEL_KEY = OTHERDB.DBO.F_MAP(b.ID)
FROM T_PERF A
JOIN dbo.T_MASTER b
on a.V_KEY = b.V_KEY

Any ideas why?
Thanks
