I have came out with a simple DAL, when i pass in stored procedure and param, it throw me exception as the following
"ExecuteNonQuery requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized."
I've got this code and it opens the database connection in debugging (and i've used the wrong password to test that it fails) but when i come to ExecuteNonQuery I get this error
ExecuteNonQuery: Connection property has not been initialized.Here is my code.VB.NET
Public ConnectionString As String = "Data Source=JOHN-PCSQLEXPRESS;Initial Catalog=RLNZ_11;User Id=App;Password=Password;"Dim connection As New SqlClient.SqlConnection(ConnectionString)connection.Open()
Dim command As New SqlClient.SqlCommand("INSERT INTO news (ID, NewsID, NewsTitle) Values (@ID, @NewsID, @NewsTitle)")command.Parameters.AddWithValue("@ID", "")command.Parameters.AddWithValue("@NewsID", NewsID)
command.Parameters.AddWithValue("@NewsTitle", NewsTitle)command.ExecuteNonQuery()
this code is in the button click , i get each data out using spiltbut i encounter error at "cmd.CommandType = CommandType.Text"

I'm passing in a sql command such as "EXEC StoredProc 0" into a a function called ExecMyCommand where StoredProc is a stored procedure taking a parameter of 1 or 0.It works fine with the following code.I had tried to judge success by looking at NumRowsAffected but soon realized that the -1 could represent a successful run even if -1 was the return value.So then I changed the code and return mLastRunOutcome = False if there is an error.So for testing I changed the name of the SP to like StoredProc2 in the database and ran the same command "EXEC StoredProc 0" and to my amazement, no errors were thrown in the code below..Of course ran the same command in Query Analyzer and it barked that there was no SP by that name.How do I know when a command ran successfully or not in code here? and Why didn't the ExecuteNonQuery throw an error when the command was not right??[code]
View 2 RepliesI keep getting a syntax error on the ExecuteNonQuery command. I am sure that the table names and column names are correct. Anyone see what I am doing wrong? Am I using any reserved words as column names or something?

I'm testing my program, which uses an access database, and it works just fine on:

But in Windows 7 with .Net Framework 3.5.1 I'm getting an error in the ExecuteNonQuery() line when updating a record in the database.

I have a program where a user can update their Password by Entering their old password in a textbox, and entering their new password in a separate textbox.
An update query then updates the database with the new password.
CODE:
However, everytime the code gets to cmd.ExecuteNonQuery(), it throws up an error saying that there is a syntax error in the Update query. However, If I use this query in Microsoft Access, it works fine so the Update query itself is written correctly. What could be wrong?
Note: I am using an UPDATE query in another piece of code within the same Sub routine and it works there. Its something about this query.
Note Again: If I change the Update query to UPDATE Users SET EMAIL = '" & tbPassword.Text & "' WHERE userID = " & Row.Item(0)" it works. Something about Password that throws that error.
Is there any way that i can be able to get the ExecutenonQuery to Execute faster. Am using it to run mysql queries that have joins from diffrent tables. As I have come to notice, the user has to wait a while before the statement ExecutenonQuery can be completely executed.. is there any way that I can get it to execute faster?

View 3 RepliesI have this generic routine that I wrote that takes a list of sql strings and executes them against the database. Is there any way I can make this work faster? Typically it'll see maybe 200 inserts or deletes or updates at a time. Sometimes there is a mixture of updates, inserts and deletes. Would it be a good idea to separate the queries by type (i.e. group inserts together, then updates and then deletes)?I am running this against an ms access database and using vb.net 2005.

i want to delete data from database,but i can't. i think it's because the executeNonQuery is being converted to string..here is my code :

ra = CStr(kongkon.ExecuteNonQuery) ---> i think this is the problem

Probably, I just need another pair of eyes, 'cause I can't see what am I doing wrong Could this be related to the database and not to my code?
Everything I read says calling an SQL Server stored procedure (SP) via ExecuteNonQuery .ExecuteNonQuery(cmd) should return the number of rows affected. When I run my code it successfully inserts a new record but it returns -1. The SP itself is coded to return (0) if successful else return (-99). It is these values that I want to test after execution. I have tried to add a return value parameter to the DBCommand but this causes an error on that parameter: Quote:

UPDATE: I've modified the code to drop the indexes before the inserting, but it makes not difference.I've been asked to resolve an issue with a .Net/SqlServerCe application. Specifically, after repeated inserts against the db, performance becomes increasingly degraded. In one instance at ~200 rows, in another at ~1000 rows. In the latter case the code being used looks like this:
Dim cm1 As System.Data.SqlServerCe.SqlCeCommand = cn1.CreateCommand
cm1.CommandText = "INSERT INTO Table1 Values(?,?,?,?,?,?,?,?,?,?,?,?,?)"
For j = 0 To ds.Tables(0).Rows.Count - 1 'this is 3110
[code]....
The specifics aren't super important (like what 'tbl' is, etc) but rather whether or not this code should be expected to handle this number of inserts, or if the crawl I'm witnessing is to be expected.
when i use TOAD to update a table all works just fine when using this query:
Update CSR.CSR_EAI_SOURCE ces
Set (STATUS_CODE, COMPLETE_DATE, DATA) =
(SELECT 'ERROR', '', REPLACE(REPLACE(c.Data, '...', ' '), ''','''')

It stays on the ra = OracleCommand.ExecuteNonQuery() continuously until i get the error The CLR has been unable to transition from COM context 0x3327fa8 to COM context 0x3328118 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.What could i do in order to get this working within VB.net since it works just fine in TOAD when running that same query?
I add C# group too in this, because this is not VB problem but ExecuteNonQuery gives timeout. how to increase the time-out?Exact errormessage: ERROR [HYT00] [Microsoft][ODBC SQL Server Driver]Timeout expiredwe do have cms system and in that CMS I have created a IFRAME which calls this ASPX +VB code, which is in different physicall folder and it has managed Pipeline Classic. When I run this in Old application it works fine. But I copied the pages to the news server and created new application pool/website Call OldASPPAGES I get ODBC timeout on 'ExecuteNonQuery()' function below. Sometimes I works but 9 of the 10 cases I gettimeout. I checked the records and there are 247 records. But below you see there are 2 sql statements composed per Each loop. (update and insert)... 2 x 247 records = approx. 500 records.
But since the sql statement is concantenated so 1 call of ExecuteNonQuery, executue does do 500 SQL Statements.... I know this is GARBAGE, unacceptable.... But I inherited so for the moment I can't rewrite that.To the point:Below are the original statemenst: I have just added : conn.ConnectionTimeout = 240As you can see I've added 240 seconds, but I still get timeouts after approx. 30 secs... so this is not the right place.... question:- Why does this statement work in old ASP environment (without problem) and not in this environement in an IFRAME.
