SQL 2005 builds on the foundation of SQL 7.0 and SQL 2000. Knowlege of an older version will almost always apply to a newer version.

I want to pass a(numerical) value from a dropdownlist to an SQL select using the DropDownList SelectedIndexChanged event.
Here's my code so far.
protected void MyDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList MyDropDownList = (DropDownList)("MyDropDownList");
MyLabel.Text = MyDefinitionDropDownList.SelectedItem.Value.ToString();
string strSQL;
strSQL = "SELECT COUNT(*) as count from MyTable where ID= ???";
}
My problem is that I don't know what should replace the '???'. I've tried
strSQL = "SELECT COUNT(*) as count from MyTable where ID= MyLabel.Text";
but this is interpreted as "SELECT COUNT(*) as count from MyTable where ID= MyLabel.Text"
even though my debugger tells me MyLabel.Text is grabbing an OK value.
If I do strSQL = "SELECT COUNT(*) as count from MyTable where ID= 6" for example it works fine.
I think my problem is with casting?
Thanks

try:
strSQL = "SELECT COUNT(*) as count from MyTable where ID=' " + MyLabel.Text + " ' ";
Or better yet use parameters (see Colin Mackay's article here[^]) for reasons and examples.

how copy a coloumn ? from one table to another table using SQL query

What do you want to do:
copy the data from one column in a database table to a different column in another table?
If so, you need a key field that will have identical values in both tables:
Update t2 set t2.c2 = t1.c1 from t1 where t2.ct2key = t1.ct1key
This specifies that the value in c2 of t2 should be set to the value found in t1.c1 where the rows to use are identified by the field t1.ct1key having a value equal to that in t2.ct2key
If this is *not* what you want, then rephrase your question to be more specific, perhaps including and example so we can understand...

Hi..
I have used Full Text Search successfuly with English words (through a stored procedure) but when i use it with arabic words like this(in the Sql Analyzer):
DECLARE @HowManyResults int
EXEC SearchProject 'المواقع العامة','ar-SA',@HowManyResults OUTPUT
I get the error:
Server: Msg 7619, Level 16, State 1, Procedure SearchProject, Line 17
Execution of a full-text operation failed. A clause of the query contained only ignored words.
Does any one know how to solve this problem?

without seeing the stored procedure you are using, this will be difficult to guess.

Thank you for your respond...
The stored procedure code:
CREATE PROCEDURE SearchProject
(
@SearchString varchar(500),
@CultureName varchar(50),
@HowManyResults int OUTPUT
)
AS
CREATE TABLE #SearchTable
(
FieldNO int,
ProjectNO int,
ProjectName varchar(1000),
ProjectDescription varchar(1000),
ProjectImage varchar(1000),
CultureID int
)
INSERT INTO #SearchTable (FieldNO,ProjectNO,ProjectName,ProjectDescription,ProjectImage,CultureID)
SELECT P.FieldNO, PL.ProjectNO,PL.ProjectName,PL.ProjectDescription,P.ProjectImage,PL.CultureID
FROM FREETEXTTABLE(Project_Locale,*,@SearchString) AS FT JOIN Project_Locale AS PL ON FT.[KEY]=PL.ProjectCultureID
JOIN Project AS P ON P.ProjectNO=PL.ProjectNO
WHERE PL.CultureID=dbo.GetCultureID(@CultureName)
INSERT INTO #SearchTable (FieldNO,ProjectNO,ProjectName,ProjectDescription,ProjectImage,CultureID)
SELECT P.FieldNO, PL.ProjectNO,PL.ProjectName,PL.ProjectDescription,P.ProjectImage,PL.CultureID
FROM Project_Locale AS PL ,Project AS P,
ProjectField_Locale AS FL,
FREETEXTTABLE(ProjectField_Locale,*,@SearchString) AS FT2
WHERE FL.FieldNO=P.FieldNO
AND FL.FieldCultureID=FT2.[KEY]
AND PL.ProjectNO=P.ProjectNO
AND PL.CultureID=dbo.GetCultureID(@CultureName)
AND FL.CultureID=dbo.GetCultureID(@CultureName)
INSERT INTO #SearchTable (FieldNO,ProjectNO,ProjectName,ProjectDescription,ProjectImage,CultureID)
SELECT P.FieldNO, PL.ProjectNO,PL.ProjectName,PL.ProjectDescription,P.ProjectImage,PL.CultureID
FROM Project_Locale AS PL ,Project AS P,
Feature_Locale AS PFEA,
ProjectFeature AS FP,
Feature AS F,
FREETEXTTABLE(Feature_Locale,*,@SearchString) AS FT3
WHERE FT3.[KEY]=PFEA.FeatureCultureID
AND FP.ProjectNO=P.ProjectNO
AND FP.FeatureNO=PFEA.FeatureNO
AND PL.ProjectNO=P.ProjectNO
AND F.FeatureNO=PFEA.FeatureNO
AND PFEA.CultureID=dbo.GetCultureID(@CultureName)
AND PL.CultureID=dbo.GetCultureID(@CultureName)
SELECT @HowManyResults=COUNT(DISTINCT ProjectNO) FROM #SearchTable
SELECT DISTINCT * FROM #SearchTable
RETURN
GO
As i said before :this stored procedure was working fine with english words.

As a first step, try changing the data types in the SP and the internal table from varchar to nvarchar, so they expect unicode text rather than ansi text...

Should i change the Data Type for all the tables used in the stored procedure or only in the #SearchTable table?
|
|
|
|
|
At least the #searchtable, and the fields being searched in the other tables.
varchar stores only single byte text, nvarchar stores Unicode. Any UI used to display nvarchar needs to be unicode aware and select the appropriate locale and a font that supports the needed characters. Enterprise manager and query analyzer may default to both a locale and font that results in some characters being displayed as an empty 'box' character...

Hi..
I have changed all the data types used by the stored procedure (all the tables and the #SearchTable).
Each time i modify a data type for a table the compiler tell me to repopulate the fulltextIndex for that table and that what i did.
But after all these modifications i got the same error at the SqlAnalyzer.
Is there another thing i should do?

Hi..
When i used the code (part of the procedure):
SELECT P.FieldNO, PL.ProjectNO,PL.ProjectName,PL.ProjectDescription,P.ProjectImage,PL.CultureID
FROM FREETEXTTABLE(Project_Locale,*,@SearchString) AS FT JOIN Project_Locale AS PL ON FT.[KEY]=PL.ProjectCultureID
JOIN Project AS P ON P.ProjectNO=PL.ProjectNO
WHERE PL.CultureID=dbo.GetCultureID(@CultureName)
With arabic words(inputs:@CultureName,@SearchString) it works fine but when i call the whole stored procedure(SearchProject) i got the error i mentioned before..I think the problem exists in the line :
INSERT INTO #SearchTable (FieldNO,ProjectNO,ProjectName,ProjectDescription,ProjectImage,CultureID)
But i dont know what is the problem and how to solve it?Is there a problem with cultures in the temporary table?

Hello,
I have some problem with my Simple query. I just want to compare the DateTime value to a given range.
Here i am giving my query and result. In Result, I do not understand why is selects 2 and 3 numbered rows. Any Other way to Compare datetime value to Date And Time of the field of a table??
SELECT *
FROM dbo.Table
WHERE ((CAST('5/6/2006 5:08:00 AM' AS DATETIME) BETWEEN StartDateTime AND EndDateTime)
OR CAST('5/6/2006 5:08:59 AM' AS DATETIME) BETWEEN StartDateTime AND EndDateTime)
RESULT :-
1 2006-05-06 05:04:00.000 2006-05-08 05:05:00.000
2 2006-05-06 05:07:00.000 2006-05-08 05:08:00.000
3 2006-05-06 05:07:00.000 2006-05-08 05:08:00.000
Thank you

Are you sure you posted this correctly? The first datetime in the query is satisfied by the values in 2 & 3, but neither value is saisfied by row 1 in the return.
Note that BETWEEN is inclusive:
BETWEEN returns TRUE if the value of test_expression is greater than or equal to the value of begin_expression and less than or equal to the value of end_expression.
if you want to exclude the start and end values, use
SELECT *
FROM dbo.Table
WHERE ((CAST('5/6/2006 5:08:00 AM' AS DATETIME) > StartDateTime)
AND (CAST('5/6/2006 5:08:00 AM' AS DATETIME) < EndDateTime))

Hi,
Thanks for the Reply.
I have tried everyway. But Still have not been successfull.
SELECT *
FROM dbo.Table
WHERE (((CAST('5/7/2006 1:10:00 AM' AS DATETIME)) > dbo.LoadTestscheduler.StartDateTime AND (CAST('5/7/2006 1:10:00 AM' AS DATETIME)) < dbo.LoadTestscheduler.KillDateTime))
Result:-
0 0 2006-05-07 01:03:00.000 2006-05-09 01:04:00.000

I don't see your problem:
'5/7/2006 1:10:00 AM' is later than (>) 2006-05-07 01:03:00.000
AND
'5/7/2006 1:10:00 AM' is earlier than (<) 2006-05-09 01:04:00.000
Are you trying to compare just the time values, irrespective of the date?

Thanks for Quick Reply.
My Query is Long and involves join of two table. But, I found this perticular area where problem lies. I do not understand why it is not comparing with time. I want it to compare with date as well as time.
From Some of the Web site I found that I can compare Binary Values datetime field. But, when i do so, I am getting Arithmatic Overflow error. The link below has information for converting into binary. But, I does not work for me.
http://www.sql-server-performance.com/fk_datetime.asp
making even AM to PM or visa versa also does not work.
SELECT *
FROM dbo.LoadTestscheduler
WHERE '2006/05/07 1:10:00 PM' > dbo.LoadTestscheduler.StartDateTime AND '2006/05/07 1:10:00 PM' < dbo.LoadTestscheduler.KillDateTime
Can you tell me How can i convert my date to a perticular format?? Do I have to use CONVERT With/Without or In addition to CAST??
Thank you.

From the examples you provided, it does appear to be working correctly, for the full datetime value (note the bolded date values in my previous post, the date difference makes the answer valid for the given query, since the supplied date-time falls between the two date-times in the returned row.)
Why do you think it is not working? I don't seem to understand what you are trying to accomplish. Perhaps some more examples (both good and bad) would clear this up for me.

Hi,
My Problem is solved. Credit goes to you. I was not really looking in to Day when i compared my value with start and end date. There was some error in my Logic.
I am really sorry for giving unnecessary trouble. I am really surprised, How can i make such foolish thing..
Thank you very for your help.

No problem. It's easy to overlook simple things in one's own code (I do it more often than I'd care to admit). That is one of the great values that comes from having others review your code (particularly when having a problem) - they will often see things you are temporarily blind to.
