You could use sp_help.
Also consider INFORMATION_SCHEMA.TABLES and INFORMATION_SCHEMA.COLUMNS.

query database user input from ListBox

I have a problem selecting fields from a table where fields are equal to user input from a listbox. example

listbox of zip codes:

33023
[red]22300[/red]
39844
[red]29339[/red]
23883
[red]38228[/red]

user wants to retreive highlight zip codes from database.
connection working perfect.
Thank you for your help.


you could use IN. check out books on line for more info.

SELECT

<columnlist>

FROM

yourtable

WHERE

zipcode IN ( ....)

|||

Hi There:

You need to retrieve the selected item from yous listbox first. Like this:

<code>

Dim sYourZipString As String = nothing
Dim sItem As ListItem
For Each sItem In zipListBox.Items
If sItem.Selected Then
sYourZipString = sYourZipString & "'" & sItem.Text & "', "
End If
Next

sYourZipString = sYourZipString.Remove(sYourZipString.Length-2, 2) ' remove the tail

</code>

You can use a select IN clause with a parameter which use the value(s) user.

Assume zipcode field is a text field (Char(5), or varchar(5) something not a number).


<code>
Dim conn As SqlConnection
Dim yourcmd As SqlCommand
Dim strConn as string = "yourconnection"

Dim yourSQLString As String
yourSQLString ="Select * FROM youTableIncludeZip WHERE zipcode IN (@.YourZipString)"

conn = New SqlConnection(strConn)

yourcmd = New SqlCommand(strUpdateStmt, conn)
yourcmd.Parameters.Add(New SQLParameter("@.Fname", txtFirstName.text))

Dim objDR as SQLDataReader
dim yourItem1fromDB as string =nothing
dim yourItem2fromDB as string =nothing
dim yourItem3fromDB as string =nothing

Try
conn.Open()
objDR=yourCmd.ExecuteReader(system.data.CommandBehavior.CloseConnection)

While objDR.Read()

yourItem1fromDB=objDR("yourItem1")
yourItem2fromDB=objDR("yourItem2")
yourItem3fromDB=objDR("yourItem3")
' ... get what you want from you Db table
End While

Finally
conn.close

End Try

</code>

Hope this help.

Query data type of column in DB table

Hi All

I want to retrieve the data type of table column and validate the input data whether same as data type of table column before insert into database. Any suggestion?

I use asp.net + msde

Thank you.

You could use TypedDataSets or TableAdapters to ensure your data type.|||

Thank you for your help.

Could I use both functions in web programming?

I searched both functions in MSDN and seems was used by visual studio.

Thank you.

|||Yes, Typed DataSets have been around since ASP.Net 1.1, and Table Adapters are new to ASP.Net 2.0. I use Table Adapters quite extensively now. They're really easy to use once you know how to set them up.|||

Thank you very much.

any web site I can read to know the syntax? Because I am a beginner of ASP.NET

THANKS!!

|||Here's a couple of links to a good tutorial on how to create a Data Access Layer and Business Logic Layer which includes usage of TableAdapters:

http://msdn.microsoft.com/asp.net/reference/data/default.aspx?pull=/library/en-us/dnaspnettut/html/aspnet_tutorial02_businesslogiclayer_cs.asp|||

Thanks a lot.
