I am trying to make a user authentication system which pulls data from a SQL table (that has columns "UserID" and "PIN" in it).
How can I check to see what the user entered into the "UserID" and "PIN" textbox's on the page and compare those entries to the database to see if they match up? I have been able to make the below code to do the query itself, but I don't know how to check back and see if it actually returned a match or not.
Function CheckLogin(ByVal userID As String, ByVal pIN As String) As System.Data.DataSet
Dim connectionString As String = "server='(local)'; trusted_connection=true; database='test'"
Dim dbConnection As System.Data.IDbConnection = New System.Data.SqlClient.SqlConnection(connectionString)
Dim queryString As String = "SELECT [UserAuth].[UserID], [UserAuth].[PIN] FROM [UserAuth] WHERE (([UserAuth].["& _
"UserID] like @UserID) AND ([UserAuth].[PIN] like @PIN))"
Dim dbCommand As System.Data.IDbCommand = New System.Data.SqlClient.SqlCommand
dbCommand.CommandText = queryString
dbCommand.Connection = dbConnection
Dim dbParam_userID As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_userID.ParameterName = "@UserID"
dbParam_userID.Value = userID
dbParam_userID.DbType = System.Data.DbType.String
dbCommand.Parameters.Add(dbParam_userID)
Dim dbParam_pIN As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_pIN.ParameterName = "@PIN"
dbParam_pIN.Value = pIN
dbParam_pIN.DbType = System.Data.DbType.String
dbCommand.Parameters.Add(dbParam_pIN)
Dim dataAdapter As System.Data.IDbDataAdapter = New System.Data.SqlClient.SqlDataAdapter
dataAdapter.SelectCommand = dbCommand
Dim dataSet As System.Data.DataSet = New System.Data.DataSet
Hey all, I've been searching for a while and haven't really found an answer for what I'm trying to do. Here it all is and someone can tell me if I'm going in the wrong direction to solve this. I have a textbox set to a parameter of "SearchString" and a DropDownList with the SelectedValue paramter of "FilterValue". The parameters work, I've tested that. So here is the problem. I am trying to use the "FilterValue" to pick the field that the "SearchString" searches with a LIKE statement (e.g. SELECT * FROM dbo.Units WHERE (@FilterValue LIKE '%'+@SearchString+'%')) This, I've found out, doesn't work. I have this setup with a DataLayer.vb in my App_Code directory handling the SQL calls, while the normal CodeBehind is in the typical "Default.vb" page. I will post code later as I don't have access to it right now, but if anyone can explain how a filter like this would work I would appreciate it! Thanks,
So what I want is to select all the rows but either creates field that show me which Records don't match on Second field or some flag so I don't have to visual go throw and find them. Yes I can actualy write the Sql so it only pulls back the records that match on both fields but I need a way so you can look and Really see that result are true.
Hope this makes sence..
Select #Temp1.org_acronym, #Temp1.Maxcount, #Temp2.org_acronym, #Temp2.Maxcount From #Temp1, #Temp2 Where #Temp1.org_acronym = #Temp2.org_acronym
I admit I am a novice to queries and stored procedures but understand stored procedures are more secure, so I am choosing to challenge myself with a stored procedure and have not been successful at all.
What I am looking for is a stored procedure which would query the single table named Hospital, which would search from a single textbox the end user would enter the text they are searching for on a Windows VB application but is dependant on a few end user selected items.
1. The end user can select a radio button either "Starts with" or "Contains" 2. The end user can select from 6 checkboxes (Hospitals, Address, City, State, Zip, Type) to limit or expand their search from the columns in the table.
The table has 17columns (CO, PARENTCO, ADDR, POBox, CITY, State, ZIP, TEL, FAX, WEBSITE, HOSP_TYPE, OWNERSHIP, BEDS, CONTACT, TITLE, Email) but I am only allowing the end user to search by the above 6 columns and need to display the above 6 columns plus the phone, fax and website columns.
After the user clicks the search button it displays the results in a listbox and the user will then select the one they want and it displays the information in another set of textboxes.
Hopefully someone can get me pointed in the right direction! Thanks for your help!
Hi guys. I'm trying to compare the results from various stored procedures. Various stored procedures in our database got redone (refactored), and I want to see if they still pull back the same data.
Are there any programs out there that do this? Compare result sets from stored procedures? Any help is appreciated. Thanks!
I have large stored procedures in SQL Server 2005 that often get updated. Sometimes it is very difficult to recognize how one change could impact the overall results. I would like to have some sample input that I could test during changes and see it compare the data results before & after my changes. This would help me quickly identify if the results are fine to pass through.
So basically I would like an easy way to compare the results of 2 stored procedures. Any suggestions or utilites that would help me do this?
Say you have a table that has records with numbers sort of like lottery winning numbers, say:
TableWinners num1, num2, num3, num4, num5, num6 33 52 47 23 17 28 ... more records with similar structure.
Then you have another table with chosen numbers, same structure as above, TableGuesses.
How could you do the following comparisons between TableGuesses and TableWinners:
1. Compare a single record in TableGuesses to a single record in TableWinners to get a count of the number of numbers that match (kind of a typical lottery type of thing).
2. Compare a single record in TableGuessess to ALL records in TableWinners to see which record in TableWinners is the closest match to the selected record in TableGuesses.
Hi all,I am facing an unusual issue here. I have a stored procedure, that return different set of result when I execute it from .NET component compare to when I execute it from SQL Management Studio. But as soon as I recompile the stored procedure, both will return the same results.This started to really annoying me, any thoughts or solution? Thanks very much guys
Hi! I dont know if i will explain this correctly, but my problem is with reporting service. I'm supposed to Sum value in one textbox and than that sum use it in sum in other textbox.
Something like this: Sum(Fields!Abc.Value/(Fields!dfg.Value+Sum(Fields!abc.Value)),"matrix1_RowGroup1")*100 I get error msg 'The Value expression for the textbox 'textbox49' contains an aggregate function (or RunningValue or RowNumber functions) in the argument to another aggregate function (or RunningValue). Aggregate functions cannot be nested inside other aggregate functions.'
Something like this wont work either Sum(Fields!abc.Value/ReportItems("textbox56").Value)*100 Error The Value expression for the textbox 'textbox55' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers.
So, pls help if you know how to reference textbox in other in body of report. Thx.

hi, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!
I have four tables: Customer (CustomerId INT, CountyId INT), County (CountyId INT), Search(SearchId INT), and SearchCriteria (SearchCriteriaId INT, SearchId INT, CountyId INT, [others not related to this]).
I want to search Customer based off of the Search record, which could have multiple SearchCriteria records. However, if there aren't any SearchCriteria records with CountyId populated for a given Search, I want it to assume to get all Customer records, regardless of CountyId.
Right now, I'm doing it this way.
DECLARE @SearchId INT = 100 SELECT * FROM Customer WHERE CountyId IN ( SELECT CASE WHEN EXISTS(SELECT CountyId FROM SearchCriteria WHERE SearchId = @SearchId) THEN SearchCriteria.CountyId
[Code] .....
This works; it just seems cludgy. Is there a more elegant way to do this?
Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist. My current SQL statement is as follows. SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))" So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated. Thanks, James.

ErikGalvezMelville82625180.7200000.7307691.24000011322101015 As you can see, all teams except for Safe Haven's have the correct AVG and OBP. Since AVG is simply H/AB, it doesn't make sense for Gabriel Helbig's results to be 1.00000. Can anyone shed ANY light on this please?Thank you in advance,Markuu ***As a side note, could anyone also let me know how I could format the output so that AVG and OBP are only 3 decimal places? (ex: 0.719 for the 1st result)***
Hi, I have a web form that lets users search for people in my database they wish to contact. The database returns a paged set of results using a CTE, Top X, and Row_number(). I would like to give my users to option of removing individual people from this list but cannot find a way to do this. I have tried creating a session variable with a comma delimited list of ID's that I pass to my sproc and use in a NOT IN() statement. But I keep getting a "Input string was not in a correct format." Error Message. Is there any way to do this? I am still new to stored procedures so any advice would be helpful. Thanks
Hi, when I copy and paste results from query analyzer into Excel it appears that values with zeroes at the end loose the zeroes. Example, if I copy and paste V128.0 into an Excel cell it comes out as V128 or if I copy 178.70 it displays as 178.7 - any ideas? I'm using SQL Enterprise Manager for 2000.

Hey I got a SQL DB with three tables, where two of the collums of the main table gets its data from two other tables, ok? Now, on one page, called "search" the user should be able to search in the DB, and on another page the user should be able to register some keywords, my question is how can the user register several keywords in the same textbox, using perhaps a ; as a separator between the words? I hope you understand what I mean..
Hello How do u update the datafield of a row using buttonClick in vb? I have a details view whereby it will display the username and timeleft once log in. currently the datafield, timeleft on one user in the database is null. I'm using sqldatasource. Once log in, it will direct to this page where the user enters a code on the textbox and click the enter button. This will cause an update on the user's timeleft. But the code must not be entered to the database. For eg. If code = 1111 then 'update timeleft = 60 The timeleft is in minutes. 60 will be stored as double in the user's row in the database. How do i do this? Please help asap. Thanks! :)

I am working with a Detailsview. I am displaying information from a number of different tables, and so when I configure the datasource I have to specify a custom sql statement. I can get it to display the right columns, but I cannot seem to be able to use a where statement. I am wanting to display the info in the Detailsview based on what is entered into a textbox, but I get an error when I try to add in the where statement. Can someone tell me what I am missing here? Thanks
Hey guys, I am trying to create a report which features a lot of textboxes side by side, but I have the problem that even though they are the same size when the textboxes are placed side by side or above or below another textbox and then the preview tab is selected they often look different for example they may not be aligned correctly or the borders look thicker in different textboxes.
I'm trying to assign multiple values to a textbox and I'm receiving an error. The error says, "The value expression for the textbox AcctName contains an error." The first value is account number and the second value is account name. An example follows:
1234 - SPC Travel Agency
My expression for the textbox contains the following:
I have a report with parameters but I show the parameters in a combo box (drop down list) with the valid values only, so, I need a single text box that autocomplete what the user types, could you help me with this please?
Hi, A report that looks perfect in the report designer has a minor problem when rendered. The textboxs widen if data is in them. If they are empty they are the proper length.
Do anyone know how I can replace or Substitute the current value of a form textbox with another value.For example, the string "YES" appears on the textbox but hit the SAVE button I would like "TRUE" to be entered in the SQL Server database table. Thanks.
