Reading Profiler Data
Oct 6, 2004
Hi, am trying to analyze output of profiler
I execute sp_sp_alex
Profiler results
CPU = 108
READ = 0
WRITE = 109
DURATION = 1709
code from sp_alex
step 1
read data from table A into cursor
(500 rows)
step 2
fetch cursor and if values in cursor do not exixts in table B(has 1000000 rows) then insert cursor data into table B
How I undestand result provided by profiler
CPU = 108 good or bad ?
READ = 0 good ,took no time read data ,all indexes in place
WRITE = 109 mmm.... something really wrong with writing to disks , why it took so long to insert 500 records
DURATION = 1709 good or bad ?
How would you read profiler results ?
Thank you
Alex

Hi guys,
Im not really sure how complicated this is but we shall see. Im running a .exe compiled from 4GL which accesses the database. But when I run a trace on the database no application name is picked up. Does anyone know how SQL profiler finds the application name or what is required in the .exe file for SQL profiler to see the application name?
This would be a great help if anyone has any information.
Many thanks,
Querix

I'm built a trace in SQL Profiler and I have selected columns "DatabaseName" and "Filename" (among others) to be displayed. When I run the trace, the columns are displayed but the values are blank. The SQLServer 2K version is 8.0.760. Is this a bug or am I missing something?

I run Profiler against my production Db to keep an eye on poorly performing t-SQL batches and SPs. There's an "Error" column in the profiler output. According to BOL (topic:Describing Events by Using Data Columns), Error = The error number of a given event. Often this is the error number stored in sysmessages.
The profiler output usually shows "0 - OK" in the error column. But it sometimes shows "1 - Error" or "2 - Abort" in this column. What do these error messages mean? I've looked around but haven't been able to find anything more detailed about what these two messages mean and how I can perhaps dig deeper to figure out what's going on. (When these values are displayed, CPU is usually taking a beating and the SPID runs this for at least 30 seconds before displaying information pertaining to this SPID).
Thanks much,
Smitha

I posted this in the Windows Forms Data Binding section, and they directed me to the .Net data section. I posted it there and waited a week with no replies. I'm hoping someone here can at least give me an idea of what the problem might be.

Not sure if I am posting this in the correct placed. Here is what I am trying to do. Read an xml files which is very large and is our store xml file. I want to import this data into a database nightly. I can down load the file and I have noticed that it has one line in it that will keep me from reading it: <!DOCTYPE StoreExport SYSTEM "http://..../doc/dtd/StoreExport.dtd"> Once I removed this line I can get the data needed to go into the database. I would removed the old table first then replace it with the information from here.
Can anyone help. I hope I have given enough information for this type of issue. I was told integration services would do this, but I am not sure how. Could someone point me in the right direction.
Thank you for any an all help.

I have a trigger written in C# which I have added to the insert event on a table, however, when testing it generates a "System.Data.SQLClient.SqlException; Cannot use text, ntext, or image columns in the 'inserted' and 'deleted' tables"
My code is attempting to read all the column names & the data contained in them as the record is created, so a solution that allows me to read all the data from each column is what I am after.
Code Extract:
public static void splTrigger()
{
SqlTriggerContext triggContext = SqlContext.TriggerContext;
// string userName, realName;
SqlConnection connection = new SqlConnection("context connection = true");
connection.Open();
SqlCommand command = connection.CreateCommand();
SqlDataReader reader;
string data = "";
switch (triggContext.TriggerAction)
{
case TriggerAction.Insert:
command.CommandText = "SELECT * from " + "inserted";
reader = command.ExecuteReader();
//userName = (string)reader[0];
//realName = (string)reader[1];
// prepare data as name value pairs
for (int i = 0; i < reader.FieldCount; i++)
{
data = data + reader.GetName(i) + ":" + (string)reader[ i ] + " ";
}
break;
...
}}

Hi,
My first post.
Problem:
I have 2 tables EmployeeA(Eng) and EmployeeB(Spanish) kept in seperate mdb's. I want to add the records into Sql Server 2005 table called StateEmployee.
Procedure:
1. Loop through 2 folders..one containing table EmployeeA in mdb and other containing tbl EmployeeB in diff mdb's.
2. Pick a file from EmployeeA and EmployeeB, both at the same time.
3. Count the total no of rows in both files. If equal proceed.
4. Compare the 'employeeid' of one row of employeeA to the employeeid of EmployeeB.
5. If employee id matches, load both the rows in Sql server else file it to the error table.
6. Loop through all rows simultaneously till end of row.
7. Go to next mdb.
How do i go about this step by step. I am fairly new to SSIS. I asked my other friends too but they have complex answers which i couldnt follow. Hope someone gives an 'easy to understand' solution with sample.
thanks.

Hi Everyone,
I am looking for some help, as i am pulling my hair out looking for information.
I have been using asp for many years and am now starting to learn .net. so far so good....
I am now wanted to connect to a database, execute a simple select statement and then read/write the information out. I can't help but think in old asp code and i am having a hard time finding what i need to perfom this simple task.
I have used the grid controls etc, and these are very good - however, i need to connect to a database in the code-behind file and perfom various functions in the background.
If any of you could be so kind as to perhaps show me some demo code i would be grateful.
I would like to do:
A) Connect to a database (sql server 2000)B) Execute a simple SQL select statementC) Read the returned informationD) put this information into variables used elsewhereE) how do you check if no records are returned? such as the .EOF in asp?
Many thanks
Darren

I need to read a very big table more than 60,000 record but it is giving the following problem: But if it is small table there is no problem. Same problem also views.
Server Error in '/POBuilds' Application.

The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

I have a database that contains news items. There's a column that contains the actual article. In that field, there are paragraphs with page breaks. The page breaks in the database are represented as squares (unrecognizable characters I guess). When I try to read in the data, it doesn't recognize the page breaks, and it comes out all in one large paragraph. Is there any way to get around this?

Hi,
I have a data structure called 'Quote' which contains a number of different variables and controls ranging from text boxes, check boxes and radio buttons, i need to be able to read and write this from a database.
First I think a description of my overall project is needed:
Project Description
I have been given a brief that basically says: i have to create a programmed solution in VB to solve a problem. This problem can be anything we like, and I personally have chosen to create a program that manages quotes for building Log Cabins (this is very contrived and far from anything someone would do in the real world).
My solution will allow a generic user to create a quote (using a form with controls such as text boxes, check boxes, radio buttons) , and then save this to file. These users may then wish to load/edit this quote at a later date, from another form.
Whilst completing this project, i'll only have up to about 5 records (quotes) within the system, so i dont need the ability to store hundreds of records. And each record will be relatively short, with only about 10-15 data items within the data structure.
Also the Admin (or business owner in this case) need to be able to view all saved quotes in a presentable format, and edit them if needs be, from within this same program.
This solution does not need to be absolutely perfect and 100% efficiently coded, or have all the bells and whistles a real-world program would have. This is for an A level computing project by the way.
So basically, i need to be able to read from the database (to populate a Data Grid (i imagine this is best way?)) and so Admin can access any quote and edit it (editing is not vital, but viewing/printing is. Maybe i should stop at just viewing any quote?). Also i need generic users to be able to fill in the Edit Quote form and then save this data into the database.
And is a data structure really required for me to use a database?
I've never used databases in VB before (but have used them elsewhere, mainly Access) and so am completely new to this. Any help will be much appreciated.
Thanks

Hi, i'm writing a SOCKET Port Listener for a Database, it must be multi-threaded and listen on a port for a record that when it comes in, it must write the record to the SQL database (MS SQL Server). I've got the listener to read the data over the port already and write the record into a string which i have already sliced up. Now i need to create a connection to the database and insert the variables into the database.
If Someone will please be able to give me a rough idea of how i could accomplish this with some sample code, then i will be greatful, i'm new to C#, but here is my code that i have so far.
//This is the Connection that i have made and where i am currently stuck, i dunno how to go further. Any help will be welcome.
public class ConnectionToMSDatabase
{
public void InsertDataIntoDatabase(string TableName, string connectionString, string dataFields)
{
string InsertSQLStatement;
InsertSQLStatement = "INSERT INTO " + TableName + " VALUES (" + dataFields + ")";
OleDbConnection ConnectionToDatabase = new OleDbConnection(connectionString);
ConnectionToDatabase.Open();
OleDbCommand command = new OleDbCommand();
command.Connection = ConnectionToDatabase;
command.CommandText = InsertSQLStatement;
command.ExecuteNonQuery();
command.Connection.Close();
}
}
//Here is my connection string, all the retrieved data is stored in a string array call fullRecord
ConnectionStringToDatabase = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;User ID=" +
"Administrator" + ";Initial Catalog=FORGE;Data Source=FORGE";

I have text output files which are semi-structured.(Headers + irregular length tables below)
Is there a simple method of getting them into sql format(line by line) to try and extract data from them?
I know this won't be easy but its been worrying me for a long time. I have a method of importing the data into excel, but although difficult, it must be possible to get a system to get it into sql server. This must be a fairly common issue.

hi there,
I installed the Adventureworks sample database and can see it from the server managment studio express. I am doing now an tutorial from Microsoft to display the data in a grid view using Visual Web Developer 2005 Express.
I am connecting to the DB with this connection string: "Data Source=STK-SASA-MX025SQLEXPRESS;Initial Catalog=AdventureWorks;Integrated Security=True" and I can see all the tables of the database. When I try to select some fields from the database using the wizard, like: SELECT [Name] FROM [ProductCategory] I get the following error message:
Invalid object name: ProductCategory, and to check the syntax and the types, but it seems to me quite standard SQL.
Anybody could help me please?
Thanks

Hi,
How would I be able to query a table (ie. all people with last name 'Smith'), have that set of data outputted to a regular text file (in a formatted way)
And what's the best way to manipulate that set of data to let's say update a Yes/No field in that table to mark that that those individuals('Smith') which were outputted in that text file?
What about the reverse? If I got a regular text file with Last Name, Social Security(delimited by tab), etc is there a way I can get SQL Server to read that text file and make an update to the database based on the Social security in that text file.
Any help would be immensely appreciated!

I execute the stored procedure specifying acDataBuf as 0x21222324252627 which translates to "ABCDEFG" ascii codes.
The resulting field display is !"#$%&' which is hex: 0x01020304050607 (the "2"s got dropped)
When I modify the code by adding a line sval="hello" the resulting field display is "hello" This tells me as long as sval is assigned a proper string, the rest will work ok.
So something must be wong with the line String str = .....
Code Snippet
[Microsoft.SqlServer.Server.SqlProcedure]
public static int vciWriteDataCS
(
String acPointType,
String acPointName,
String acVECName,
byte[] acDataBuf,
int iLen,
int uiOffset
)
{
using (BinaryReader rdr = new BinaryReader(new MemoryStream(acDataBuf)))
{
String sval = Encoding.ASCII.GetString(rdr.ReadBytes(FieldDef.iLen), 0, FieldDef.iLen);
vciSqlCommand.Parameters.Add(new SqlParameter("@data_params", SqlDbType.NVarChar));
vciSqlCommand.Parameters["@data_params"].Value = sval;
Any words of wisdom?
