Yea I have a linked record showing in a child view.
So from what I can gather the first query executes to fill the main record table, and then a second query populates the correct record in the grid view (and a few other text boxes on the form).
It is working now - but is it worth the time to write it as it should be? It won't affect any of my datasource bindings by combing it into a single query will it?

It's already as it should be; if you have a separate grid for the children, you'll need a second query. Also explains why the second grid might get an empty resultset.

It would! The net effect is that you only pull the data over the network-line once. You're using a different concept here - if you'd fetch all tables, you'd probably have fetched a lot of child-records that the user isn't going to use. That means that your current approach might be the more efficient one, depending on what the user does

Hi Joe,
You can use following query:
SELECT ISNULL( (SELECT File_Name
FROM Files
WHERE File_Name = @FileName1),1)
This would solve your problem, in case there is no result, it will return you 1 otherwise the matching result.

There are also a number of other columns for each row, I assume that I just populate the query with those separated by columns?
|
|
|
|
|
Yup
SELECT Col1
,ISNULL(Col2, '1')
,Col3
,Col4
FROM SomeTable
WHERE SomeCondition
..or even nest another select, like this;
SELECT Col1
,ISNULL(Col2, '1')
,(SELECT 1) AS Col3
,Col4
FROM SomeTable
WHERE SomeCondition

Darn, you're right 
I was returning the value as a VARCHAR, not an INTEGER - well spotted.

Hi,
U can use following statment..
SELECT ISNULL(File_Name, '')
FROM Files
WHERE File_Name = @FileName1
because is is string so it should return blank
|
|
|
|
|
Try the following query.
SELECT CASE WHEN COUNT(File_Name)=0 THEN 1 ELSE COUNT(File_Name) END as FileName from tblname
WHERE (File_Name = @File_Name1)

Only goes wrong if you concatenate strings, which shouldn't be done in the first place. Use a 'parameterized query';
using (cmd = new MySqlCommand("SELECT EmployeeName FROM Employees WHERE EmployeeId = @P1;"))
{
cmd.Parameters.AddWithValue("@P1", Parameter1);
m.ExecuteNonQuery();
}
Research the AddWithValue member.

Change this;
N'<Article type=''Pages''>
to this;
N'<Article type="Pages">
..and do the same for the "ucl name".

Building a dynamic query in SQL, even inside a stored procedure, will not prevent SQL injection[^].
Your example could easily be rewritten as a simple UPDATE statement. (NB: Constant values like 100 are never null!) If any of the new values are passed in as parameters, then your query is open to SQL injection.

Hi,
I my Self solved the problem via this strategy
Change the bellow code :
if @ModuleSettings is not NULL
BEGIN
set @param = @param + '[ModuleSettings]=''' + <code>@ModuleSettings</code> + ''','
END
With :
if @ModuleSettings is not NULL
BEGIN
set @param = @param + '[ModuleSettings]=''' + <code>replace (@ModuleSettings,CHAR(39),char(39)+CHAR(39))</code> + ''','
End
conclusion :
you should replace :
@ModuleSettings
with :
replace (@ModuleSettings,CHAR(39),char(39)+CHAR(39))

I believe I've found a very unexpected bug in SQLBulkCopy that took me a while to track down. My test program reads in records from a CSV file with exactly 1 column which is defined as a "numeric(19,5)" for statistical uploads.
Condition 1:
If the input file has 25 rows with the only value being the digit zero, followed by a number with a decimal (like '1.23456'), the data is imported perfectly.
Condition 2:
If the input file has 26 rows with the only value being the digit zero (or any non-decimal number), followed by a number with a decimal (like '1.23456'), the data is imported and the last (and any subsequent) rows have the field imported with truncated decimal digits (like '1.00000').
Condition 3:
If the input file has 26 rows and the first row is '0.0', all of the rows are imported perfectly.
I've checked the table/field definition for Condition 2 and it's the same as 1 and 3 so there's no manipulation of the field type (as far as I can tell).
Is this a bug or am I missing something?

You say the test file has "1 column".
Then you say that each row has "the digit zero, followed by a number with a decimal (like '1.23456'),"
Does that mean that it has two columns or that the single number is '01.23456'?
Also you should post the following
1. What database version you are using.
2. Example data
3. The relevant code.
4. The database schema you using.

Re: the numbers
The test only had a single column although I first noticed the behavior with 100 columns. Each row only has 1 value (zero) until the 27th row which is the decimal number, i.e.
0
0
0
...
0
1.23456
Re: other questions
1) The destination was SQL Server 2008 and the SQLBulkCopy came from the .Net 4.5 library. This brings up the question "Is the SQLBulkCopy the culprit or the destination SQL Server instance?"
2) Example data: see above
3) Relevant code
using (SqlConnection connection = new SqlConnection(strConn))
{
connection.Open();
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection))
{
bulkCopy.DestinationTableName = strSQL_table_name;
bulkCopy.BatchSize = GetBulkCopySize();
bulkCopy.BulkCopyTimeout = 2000;
bulkCopy.NotifyAfter = GetNotifyAfter();
bulkCopy.SqlRowsCopied += new SqlRowsCopiedEventHandler(OnSqlRowsCopied);
try
{
bulkCopy.WriteToServer(results);
}
catch (Exception ex)
{
string error = ex.Message;
MessageBox.Show("Error(CSV_To_SQL-a): " + ex.Message);
return;
}

Where is the reader ('results') close?

I presume results is a datatable, have you inspected the content of the table before BC?
