Hi all, thanks for looking
I need a storedprocedure that retrieves rows based on parameters
Example 1:
SELECT * FROM Users WHERE Name LIKE '%' + @str + '%'
This will return all rows that have the word @str in Name column
If i pass '' or '%' it will return all the rows
I need the same but for an int column
Example:
SELECT * FROM Users WHERE UserID = @UserID
If i pass a number, it will return a row of the user with UserID = @UserID
But if no parameter is passed it wont work
My question is
Is there any way i can make this last query to return all the rows if no @UsersID is passed
Ill be calling this SPs from ASP.NET
Im giving this examples, i know they might seem very easy, and you may say, make 2 SPs
But in fact, Ill have more than 5 diferent filters, all applied to the same table, and any combination of this parameters is valid (param 1 and param2, param 1 only, param 5 only, param 1 2 and 4, and so on), so if i implement this in separated SPs ill end up having more than 20 almost equal SPs
Any advice will be appeciated
Thanks in advance

Hey, thanks for the link
I solved part of my problem with this:
select * from table where col1 = isnull(@param1,col1)
works great
But i have a little different scenario here
One of the parameters is for a function that returns a table, it accepts a string and splits it returning the values as one column rows, like:
select * from fnSplitString ('1,2,4,5,6') Will return:
Value
1
2
3
4
5
6
select * from table where col1 = isnull(@param1,col1)
and col2 in (select * from fnSplitString (@param2))
This works when i pass param2, but if param2 is null i need all the rows
Can this be done with a single query or do i have to make N queryes
I was gonna use for the function something like this:
select * from fnSplitString (isnull('1,2,4,5,6,','String with all posible values but seems inefficient and values can change'))
Any way to omit the second condition when @param2 is null (with single query and without SQl concatenation)?
Thanks in advance

use if else statement in stored procedure and use this condition
If @UserID IS Not NULL
'write your query
Else
' write query without where clause, it will display all the records
Do good and have good.

Thanks for your reply
But as i explained in my post, i might have up to 5 optional parameters and if i use if else stataments ill end up having more than 20 almost equal combinations, which i dont want to do, not beacuse i cant (they would be almost the same), but because i believe that there is a better solution for this problem
Thanks

Hello,
I need some help with a SQL query.
Example table:
Table myTable
Columns
myId, myDate
If I have rows in the table with the same id like this:
myid mydate
---- --------
1 01/01/1999
1 blank
1 01/01/1999
2 01/02/1999
I would like to filter out the id completely if I find the id has a record with a date and a record with a blank date.
If the filter works my results should be:
myid mydate
---- --------
2 01/02/1999
Id 2 remains because it does not have records with a blank date.
Thank you so much for the help.

Your request is somewhat confusing but, I think I grasped the basic concept. I assume you are using blank as a term that represents NULL.
SELECT
myid,
mydate
FROM
myTable
WHERE
myid NOT IN (SELECT
myid
FROM
myTable
WHERE
mydate IS NULL)
|
|
|
|
|
Try
SELECT myid, mydate<br />
FROM myTable mt1 <br />
WHERE not exists (select 1 from myTable mt2<br />
where mt2.myID = mt1.myid and mt2.mydate is null)
Assuming the table is properly indexed this should execute quicker as a not exists is quicker than a not in.

Does anybody know where there is an article about how to write a .HLP help file? It is my understanding that it can be done in Windows and can also be done in a web type application.

Hello there,
I have an application in VB.Net in which I import data from Excel files to SQL server database.
I'm trying to retrieve a table in Excel 2007 worksheet, which has more than 255 columns, using Ado.net 2
The problem lies in the "Select * from [Sheet1$]" statement, which will only pick a maximum of 255 columns from the Excel sheet, even though the sheet has around 260 columns.
here is my code for your review:
'*****************************************************************************
'The connection string.
Dim xlCon As String = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & lblImportFile.Text & _
";Extended Properties=""Excel 12.0;HDR=YES"""
'Excel "SELECT" statement
XlsSQL = "Select * from [Sheet1$]"
'Declare and instantiate the connection object.
Dim con As New OleDbConnection(xlCon)
'Declare and instantiate the command object.
Dim com As New OleDbCommand()
'Declare and instantiate a DataAdapter which fill the dataset with data.
Dim da As New OleDbDataAdapter
'Add values to the command object's properties.
With com
.Connection = con
.CommandType = CommandType.Text
.CommandText = XlsSQL
End With
With da
.AcceptChangesDuringFill = False
.SelectCommand = com
'Add data to the dataset.
.Fill(dsXLData, "Ratings")
End With
da.Dispose()
con.Dispose()

This is a limitation that you will have to work around. Maybe you could split the upload into 2 files, each with 130 columns.
However, maybe you should consider using a different file format. A text-based flat file wouldn't have the same problems.

Thanks Paul for your reply.
I take it that you are dead sure that no way on earth could a "Select" statement pick more than 255 columns. Right?
Your suggestion of splitting the upload seems to be the best work-around for that limitation.
Thanks again for your help. Greatly apprecaited.

Certainly not on earth.

Hi again Paul,
I followed your suggestion and split the uploads.
The problem now in the rows of second upload, instead of adding them to the same rows of first upload, they are bieng added on top of them.
To explain further, the excel sheet has 280 columns x 100 rows. In the first upload, I fill the dataset with 255 clms x 100 rows. In the second upload, I fill the dataset with 25 clmns x 100 rows, but in the end result I get a dataset with 280 clmns (cool) and 200 rows (Not cool)
Is there any way perhaps in a galaxy not far away  , that I enforce the dataset to add the rows of the second upload into those of the first upload
Greatly appreciate your help

Perhaps this might work better:
SELECT * from [MyNamedRange]
or
SELECT * from [Sheet1$A1:B10]

<br />
xp_cmdshell failed to execute because LogonUserW returns error 1909. please make sure the service account SQL Server running under has appropriate privilege. For more information, search Book Online for topic related to xp_sqlagent_proxy_account.<br />
