I would like to combine two commandtexts into one
text1.CommandText = "SELECT Id, Heading as Head FROM dbo.Modul"
text2.CommandText = "SELECT Id, Caption as Head FROM dbo.Menu"
I want to combine these two into:
text3.CommandText = "SELECT Id, Heading as Head FROM dbo.Modul" + "SELECT Id, Caption as Head FROM dbo.Menu"
The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
give me an example of how to do this?

protected void Button19_Click(object sender, EventArgs e)
{
SqlDataSource conn = new SqlDataSource();
conn.ConnectionString = ConfigurationManager.ConnectionStrings["Database2ConnectionString1"].ToString();
conn.SelectCommandType = SqlDataSourceCommandType.Text;
conn.SelectCommand = "SELECT FROM table1 (a, b)VALUES(@a,@b)";
conn.SelectParameters.Add("a",TextBox1.Text);
conn.SelectParameters.Add("b", TextBox2.Text);
int rowsAffected = 0;
try
{
rowsAffected = conn.Selectt();
}
catch (Exception)
{
Label1.Text = "Error";
}
finally {
conn = null;
}
if (rowsAffected != 0)
{
Label1.Text = "Data saved";
}
}
well it returns error no overloading method for select (P.S. same code work fine for insert)
I will declarate a attribute, but it gives me an error
This query works fine and returns 1 record from type int:
SELECT TOP 1 DataObjectVersionID
FROM tblDataObjectVersionPropertyValueText
WHERE PropValue like CAST('00010281' AS ntext)
ORDER BY DataObjectVersionID DESC
And when I will declarate a attribute/parameter it gives me an error:
DECLARE @dataObjectVersionId INT
SET @dataObjectVersionId = SELECT TOP 1 DataObjectVersionID
FROM tblDataObjectVersionPropertyValueText
WHERE PropValue like CAST('00010281' AS ntext)
ORDER BY DataObjectVersionID DESC
Error message:
Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword 'SELECT'.
SQL Query with IF and Select
View 2 RepliesThe following code is used to get a relation out of the database:
rel_SQL = "select * from Relatie where relatie_soort_nr = '" + rel_srt_nr + "' and relatie_naam like '%" + sel_Waarde.Trim() + "%'";
This code is a problem when you have a relation with ' in his/here name.
rel_SQL = "select * from Relatie where relatie_soort_nr = '1' and relatie_naam like '%L'%'";
As you can see there is one to many ' sign in the code, how can I solve this like problem?

There may be a lot of data in the Blogs table. What if all I wanted was say BlogID, BlogTitle and BlogAuthor and nothing else, is there a way to do this in an effort to make the sql more efficent?
Along the same lines in my DataContext (.dbml) file I added some associations between some of my tables. This makes coding nice when I do a linq statement that will join those tables automatically for me but my concern is does it do that everytime, thus making all my linq quieries inefficient?
I have a query that looks like this attached to a sqldatasource :

btw the @fldbranch is pulling from a dropdownlist and so it the @year but the @cat is just defined always as 'LEAN' But im not sure what to put inside the select() part. i know you have to put atasourceselectarguments.empty if no parameters, but what would I do here since their are 3?

Select statement across three tables
I need to create a SELECT statement for a table that excluded the TOP 10 records.
"SELECT TOP 10 field1,field2,field3 FROM AppData ORDER BY field1 DESC" returns the first 10 records from the table but I need to retrieve only from the 21st record onwards.
I simply don't know how to do it because I'm not that strong with SQL. I searched the forum for some answers but can't find a solution that I can understand.
I have a problem with my SQL statement that only needs to show future dates in the Gridview.I use vb, vs 2005.I want a DateTime Field(TEndDate) to act as a control field in that only future dates (WHERE TEndDate >= Now.Date.Date) should be returned.It asks for my paramaterized value when I'm building the query.I'm unsure about the source I should select for the query.(The options are: None/Control/Cookie/Form/Profile/Querystring/Session)I'm losing my mind with this!Here is my code:

View 2 RepliesWhere can I find documentation on the syntax that is expected for LinqDataSource.Select? It seems to be different from what I would do with Linq inline in C# code. For example, concatenateing something in Linq I would normally just do this in the projection:
new { FullName = (person.FirstName + " " + person.LastName ) }
However, with a LinqDataSource the only way I've found to do this is like this:
new ( String.Concat(person.FirstName, " ", person.LastName) as FullName)
I literally spent hours trying to figure this out, and only succeeded when I found a blog where someone gave this verbatim as an example. So I still don't understand why the syntax is different, the braces versus parens, aliasing, Concat operators. Next time I do this I want a better understanding so I am not playing this guessing game. It's like being handed a compiler, and trying to write a program when you don't know what language the compiler compiles.1. Are there different "flavors" of Linq? Like a VB Linq, and C# Linq?2. If so, is the LinqDataSource using a VB flavor of Linq?3. Really, what is really important to me, where can I find documentation on this particular falvor of Linq that the LinqDataSource expects? The documentation for the LinqDataSource itself gives nothing more than extremely simplistic examples.
I have a simple page that will display data from a particular category, using a querystring to filter my data in my sql select statement.
However, I would like to show all my data if there is no querystring present. Is there a simple way to do this?
How can I select a random row and then update or delete it? I've found how to get a random row, using SELECT TOP 1 column FROM table ORDER BY NEWID() do I have to make another select using this result in order to update the row, or it can be done more efficiently?
