As you see in the images the connection is closing. During the read it counts 5 columns which is correct. When I step through the code it closes the connection when it hits dt.Load(reader) and nothing is loaded into the datatable.

We dont want to use triggers or replication to capture changes in a set of tables; we have the same problem in Oracle and we use LogMiner to do so. We have been looking for similar tools in SQL Server but the ones we have found so far dont seem to fulfill our requirements (Redgate and Lumigent). Does anyone know any other third party application that can read a SQL Server log and extract changes filtering by table name?
is it possible to use a data reader to read from 2 tables with 1 store procedure(sp)? ------------------------------------------------- ex: create sp1 as
select * from tbl1 select * from tbl2 ------------------------------------------------- how can i use a data reader to read the items from tbl2?
Hi Guys,I have a quick question about DataReader, I have a function called "ExportTotal" i am calling this function from another function. what it does is it will put the Total for each Network in the Line 34. Right now what it is doing is It is putting the First Networktotal,2ndNetwork total,3rdNetwork total....... in the line 34. what i want is if the control comes to first network then it has to put only 1st network total and for the 2nd network only 2nd network total and so on. Please see my function below.

I am trying to do incremental extract using Datasource reader. I need to send a variable in where condition to extract the data base on the max date from other table.
To implement this i have created two variables 1)to get the max date from the table. 2)to store the sql query and send the mad date from other variable to extract the data.
i have give this sql variable in data flow expression.but its not working.
I have set up the transactional replication. MY log reader process wakes up and runs every 5 min. Does my transactions will get deleted or they still in log file as active even it is in simple recover model.
Logreader how it reads the Transaction log files .? I observed today we are running some big reports. those reports uses INSERT INTO FROM <TABLE > this process showing in DBCC OPENTRAN
MY log reader keep on reading the log file.. it did not come out from that five min duration...
Can someone from the MS share the what /how exactly log reader works ( inside details)
I would like to add more details

Hi, I am trying to creating an application using C# where I read data from a SQL server. In the database, I have two tables. One that has the Order info and other table has the item info for each of the rows in the Order table. In my application I am run a query and open up a datareader to read in the Order info. While OrderInfoDataReader is still open, I run another query to get the ItemInfo and open another data reader. Well, ADO.Net does not allow two datareader be open at the same time. My question, what would be a way around to solve the issue? I would greatly appreciate your help. Thanks, Emon.

Hi, i dont know whats gone wrong! but all of a sudden it seems to be throwing an error, i have looked at my previous code and it matches exactly when it was working, here is the code below int i = 0;for (i = 1; i <= 3; i++) {
//This gets the stock ID from the textbox.string stock_ID = ((TextBox)Panel1.FindControl("txtID" + i.ToString())).Text;
//This is the sql statement.string sql = "SELECT [n_or_sh], [title], [cost_price], [selling_price] FROM tbl_stock WHERE stock_ID = " + stock_ID;

}; myConn.Close(); i = 0;
the error its throwing is this CS1519: Invalid token '(' in class, struct, or interface member declaration for the line myConn.Open() does anybody have any idea how to solve this? Jez
In my current application, I have an administration form that fills in labels and checked states via data entered into the database using a similar user input field. What the admin page does is it first lists all the record names in a listview, then on select, it fills in the form based on what the records contain. This means labels text change, and check states change based on the string "True" or "False". This was done using the SQL Reader command. Within the same form, the read checkboxes are editable via the admin. When the admin edits the controls, he will click the update button at the bottom and the database will UPDATE .. WHERE UserName = (Scalar for ListBox1.SelectedValue) I've used the exact same UPDATE command in my form for the user, except the only difference was @ the WHERE clause-- I had it updating based on a GUID. I know my SQL statement is correct, but it just won't update the data. Is it possible that the READER, which starts (and closes) on pageload cannot coexist within the same form as the UPDATE code? My code is incredibly long, so for the purposes of a short post I'm not including any bit of it-- but if you would like to see it, just let me know.
I have an SqlDataReader which loops through records returned from an SP, within that loop I would like to initiate another SP, but for some darn reason the following code won't work: // create SqlConnection object string ConnectionString = ConfigurationManager.ConnectionStrings["aiv3cs"].ConnectionString; SqlConnection myConnection = new SqlConnection(ConnectionString);
try { // Create a new XmlTextWriter instance XmlTextWriter writer = new XmlTextWriter(Server.MapPath("products.sitemap"), Encoding.UTF8);
// end the xml document and close writer.WriteEndElement(); writer.WriteEndDocument(); writer.Close(); }
finally { myConnection.Close(); }I've gotten the following two errors:There is already an open DataReader associated with this Command which must be closed first.And a build error:Error29The type 'System.Data.SqlClient.SqlDataReader' has no constructors defined Any suggestions would be most appreciated.

Is there a way I can view the transaction log mean I want to see the transactions occurred during the last few hours before the commit? And is there a way to capture all the logins who access the DB
We restored a database with replicated tables. Now, the Log Reader Agent will not run. This displays: "The process could not execute 'sp_repldone/sp_replcounters' on 'ourservername'." In Error Details for the agent: "The process could not set the last distributed transaction." And, from the logs: "ForwardLogBlockReadAheadAsync: Operating system error 998(Invalid access to memory location.) encountered."
Does anyone know how we get the Distribution database and the Log Reader running again? It is only affecting Transactional replication (not snapshot or merge).
i've performed a test on 2 machines based on the topic above, but it doesn't seem like blocking each other... This is the context...
I've created a table call TEST_DEL i.e. quote:CREATE TABLE test_del (v_id INT, desc CHAR(3) )
In machine 1, i'm login as USER 1 and try to insert a set of records into the table quote: Machine 1 ~~~~ BEGIN DECLARE @li_num int, @li_start int
SET @li_num = 100000 SET @li_start = 1
WHILE @li_start < @li_num BEGIN INSERT INTO test_del VALUES (@li_start, 'zzz', 'xxx')
IF (@li_start > @li_num) BREAK ELSE SET @li_start = @li_start + 1 CONTINUE
END END
In machine 2, i login in as USER 2 to retrieve the records at the same time... quote: SELECT * FROM test_del
but, the system still allow me to retrieve the records at the same time... May i know when will "Writer block reader, reader block writer" occur and in what situation
HELP>>> I am getting desperate we recently had a failure which ended up wrecking my replication. The basic layout is from a source server -> Distribution Server then out to several other servers. Long story short the distribution database had to be moved to a new drive and I am now getting the following error message
The specified LSN (0003d4f0:0000721e:001b) for repldone log scan occurs before the current start of replication in the log (0003d63a:00002803:0001).

(Source: fsdpdcis-DPDDATA-1 (Agent); Error number: 22017)
I have reinitialized all subscriptions on the fsdpdcis server and run subscription validation (with no response). The data did re-load during the reinitialization but does not seem to be getting updated. This is driving me crazy and I am desperate. Any suggestions would be greatly appreciated. I have search MS knowledge base with no results and BOL has not been any help so far.
Does anyone happen to know if there is a raw file reader utility available? One of my processes drops a couple of interim raw files and I'd like to be able to look at the data in them in a columnar format without having to run a downstream data flow with a reader inserted.
WMI Data Reader Task: WmiConnection = WMI Connection Manager WqlQuerySourceType = Direct input WqlQuerySource = "SELECT Name FROM CIM_Datafile WHERE Name = 'C: est.txt'" OutputType = Property value OverwriteDestination = Overwrite destination DestinationType = Variable Destination = User::WmiVariable
I've tried setting the WmiVariable to both String and Object data types. I've tested the WMI connection (both within SSIS and through a sample VBS script), and that works just fine.
I need to load data from excel files which will be provided by a number (around 100 monthly) of external suppliers, so we don't get 100% control over the files themselves.
What my solution involves is copying the excel file to a common name (e.g. supplierExcel.xls), turning this into a pipe delimited txt and then loading the txt. I had trouble switching files when trying to load directly from excel.
All these files should arrive in the same format of 36 fields and of course in the right order; there will be rejections if they fail.
I've come across a problem extracting the data from excel where I'm getting 'the value could not be converted because of a potential loss of data' on field 1. It only happens on excel files where there is a quote mark as the first character and I have loaded other files quite happily without the quotemark.
Has anyone seen this before? Is this a known issue and how can I get around it, without recourse to manually changing the individual files?
I have a SSIS package that pulls fact data from Progress 10.1B database. Midway through the pull (around 10,000 records), it bombs out with the following error. I have'nt a clue as to what it means. Could someone help me out? Thanks in advance.

Hi , I have a situation where i need to read data from one table and and the result that i get i pass it thru a where clause in another query for which i need to read the database again. Problem iam phasing is with the Sqldatareader in a while loop . When iam trying to open a SqlDataReader with in a SqlDataReader iam getting an error that i need to close the data reader that i have already opened. Is there a way to solve this problem Code: public void fnIduction() { //Calculating the Deduction of Individual Employees //Select from the EmployeeMast tableSqlCommand cmdEmp2 = new SqlCommand("select EmpCode,EmpName,DesigCode,DeptCode,BankCode,PFNo,PanNo,BankAcNo,GS,ESINo,PayrollGroup,LICNo,CategCode from EmployeeMast", cn); cn.Open();SqlDataReader dr02; dr02 = cmdEmp2.ExecuteReader();while (dr02.Read()) {strEmpCode = dr02["EmpCode"].ToString(); //Select from MondedPay,Deduction tables (Variable Deductions or Monthly Deductions)SqlCommand cmdDed02 = new SqlCommand("Select MondedPay.EmpCode,MondedPay.DedPayCode,Deduction.Name,MondedPay.DedPayMonth,MondedPay.DedPayYear,MondedPay.DedPayAmount from MondedPay,Deduction where Deduction.Code=MondedPay.DedPayCode and EmpCode='" + strEmpCode + "' and MondedPay.mType =1 ", cn);SqlDataReader drDed02; drDed02 = cmdDed02.ExecuteReader();while (drDed02.Read()) { strMonDedNam = drDed02["Name"].ToString();dobMonDedAmt = Convert.ToDouble(drDed02["DedPayAmount"].ToString());if (intDedPer == 1) { dobMonDedAmt = (dobDedAmt * dobBasic) / 100; dobMonDedTot = dobMonDedTot + dobMonDedAmt; } else { dobMonDedTot = dobMonDedTot + dobMonDedAmt; } } drDed02.Close();
By default, the Log Reader Agent and Distribution Agent use the account the starts SQL Server Agent to logon into the Publisher SQL Server when performing SQL Server Transactional replication. Is there a way of configuring them so they use a different account.
In ReplMon, some Log Reader agent jobs display as "not running". Rigt-clicking on it the only option is to "Stop" the agent. Seems to me if it's NOT RUNNING you should be able to Start it but that option is disabled. Also, looking at the Agent Job Activity Monitor on the distribution server it says that the job is currently executing.
Running the Replication Agents Checkup job yields nothing and those jobs are still "not running". I can easily Stop/Start the Log Reader in ReplMon or insert a tracer token and then all looks fine. I'm just puzzled by the inconsistency and wondering how I can programmatically check and resolve it.
Can anyone provide an example or point me to an article that explains how to programmatically set the SQL command for a data reader. I am using a data flow task in a For Loop Container and want to change the SQL command for each loop based on the data from the previous.
I recently set up transactional replication from one server database to another server database. I keep getting a Log Reader Agent error: An access violation occurred.
The SQL Server agent starts under one Windows account but the Server is registered under the system account. The log reader agent is using the system account.
I'm not sure what else to check or what database permissions or roles should be set. Can somebody help? Thanks.
maybe you can help me with a little SSIS task. I want to fetch some wmi infos from serveral servers with the wmi reader. to read something is no problem, but whats the best way to bring them to a table or the control flow? Read from the generated file cant be a way. I also tried the variable. How do I get them to data flow. I tried a script task but i cant read the resultset. What format has the variable? ado.net, ado? Whats the best way to get the results into a table?
