Asp.net - Escaping Apostrophes With Parameter Query Not Working?
Nov 28, 2011
I am trying to prevent from having to escape apostrophes in my string variables by using a parameterized query with a OleDbConnection, but it is not working. I am trying to insert into an Access db and I keep getting those pesky html codes.
Dim pConn As New OleDb.OleDbConnection
pConn = New OleDbConnection(cb.ConnectionString)
Dim SqlString As String = "INSERT INTO Strings (Mlt_String_ID, Lng_ID, Strg_Name, Sht_Text, Lng_Text, Alt_Text) Values (@Mlt_String_ID,@Lng_ID,@Strg_Name,@Sht_Text,@Lng_Text,@Alt_Text)"

I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" & "*" & CStr(TextBox1.Text) & "*" The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ? or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed. Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function: [Code]
I am trying to filter fields in a table that contain percent (%) and apostrophe (') characters. I kow that to filter an apostrophe you need to add another apostrophe (''). However, when a text contains the percent (%) character in combination with an apostrophe (') character, an exception is thrown. Also, when using the % character in a filter string, it will be function as an "*" (fields starting or ending with). I need the % to be considered as a character whenever the % makes part of a string in the field.

How do I add a wildcard parameter to my query. Im using a mysql database. The following doesn't work:
Dim occCmd As New MySqlCommand("SELECT occupationid,descr FROM occupations WHERE lcase(descr) like '?descr%';", con) occCmd.Parameters.AddWithValue("?descr", prefixText)
Dim tbl as String = Request.QueryString("tb") 'tb value = User Dim sql As String = "Select * From @table Where @Col = @ColVal" Dim para As New SqlParameter
[Code]....
what should I do to run the sql with given table name as parameter and avoid the sql injection.
I'm stumped here - the folowing code errors with Procedure or function 'importsp_CreateDiallerBatch' expects parameter '@BatchName', which was not supplied[code]...
When debugging the code, BatchName definitely has a value, and checking the parameters collection of cmd right before executing the urey shows 2 params, both named and with values set exactly as expected. I must have written code like this a thousand times
I am trying to load a combo box based on a selection of data from another combo box. I am not sure how I would pass the value to the object. My thought is I am loading all the table data onto my object and then I would run the query on the object. However I am at loss as to how I would go about doing that.

I have a query in a myTableAdapter that ends with WHERE column IN (@S). This works fine when I use myTableAdapter.Fill(dataset.table, "text") but I can't find any way that works to provide multiple text strings such as "text1, text2" for the IN parameter.

I have a sql stored procedure with an output parameter. I'm just trying to read the output parameter in my code and I just cannot get it to work. The error I get is: "Procedure or function 'GetFolderData' expects parameter '@RootName', which was not supplied."
It looks like I am supplying this but it's not working.
Here is my stored procedure:
ALTER PROCEDURE [dbo].[GetFolderData] ( @RootID int,
Consider the below code (which dynamically creates a dynamic SQL string) Is there a way to further compact string.join, so it does replace("'","''") on all array members automagically ? (without writing a custom version)
I am using following code to connect to my database. Dim conStr As String = "Data Source=.SQLEXPRESS; ![enter image description here][1] AttachDbFilename=|DataDirectory|dbTest.mdf; Integrated Security=True; User Instance=True" Dim sqlQry As String = "SELECT * FROM [tblTest] WHERE ([Name] = @Name)" Dim dAdt As New SqlDataAdapter(sqlQry, conStr) Dim dSet As New DataSet()
Then filling adapter with dAdt.Fill(dSet, "tblTest") And then I can use the data the way I want.
My question is: How to pass the value of parameter that user will give through a text box on my webform. Dim sqlQry As String = "SELECT * FROM [tblTest] <b>WHERE ([Name] = @Name) I mean how to pass the parameter value to my query?
I want to pass a date as parameter in vb to query the data from the table.If I hardcore the value in the query it works fine for me, but if I pass it as parameter to query, like I am getting the data from edit text and trying to send that as a parameter, this does not work.
SELECT * FROM VehicleAnalogParamDownload2 WHERE Vapd2_Date between 'From_date.Text' And 'To_Date.Text'

I have the following query... The only unique identifier i can use is the Primary Key (Access backend). I have a txt box on the form that displays this... I know this is not the best way to accomplish this. But my problem is the datatype here. This is my query:
I am now able to add a row to Table1 in my database and and to populate some text boxes with that data. Now...one of those text boxes has a piece of data I wish to use as a variable/parameter in a SQL query to then populate several other text boxes. The piece of data in question is the Primary Key in a Table2. I have tried several methods I've discovered online...but nothing is working so far. So far I'm leaning towards the CommandBuilder but am unable to make it work.
Unable to create a parameter query using the table adapter wizard to process an access db file. Went online and attempted to create an instance for new adapter with out success, when I click finish the wizard does not like the in the query WHERE (Last_Name LIKE @Last_Name).

I'm using a datagridview to display data and make updates to my access database. I was able to display data from my database to the datagridview but it is not filtered. The datagridview displays all the records on my database. I tried using query builder to execute sql select statements that will filter the data and this is where I'm stuck. Im using a variable as a parameter to the sql statement and I dont know what syntax to use in Query Builder. I tried to use @varname, '" & varname & "', and
how to pass a parameter to a predefined parameter in a dataset. I've found everywhere a solution if you build the sqldata adapter and the dataset in the code. Then you can pass the parameter like: da.SelectCommand.Parameters.Add("@param1", SqlDbType.Char).Value = param1_variable (as example)
But if you have builded a dataset (with table adapters), and then in the form app you want just to pass the param1 to a DataGridView1 (as example) which is using the table adapter, I did not find how to do this.

I have this code to retrieve a record to fill out a tooltip when the user's mouse enters a cell of a datagridview.
Dim dacmt As OleDb.OleDbDataAdapter Dim con As OleDbConnection Dim sql As String
[Code]....
This takes way too long for the tooltip to display. So, I created a query in the Access database that takes a parameter of the first field for the record you want.
How do I connect to just the query and send the parameter to it?
I am thinking this might be a quicker way to get the data for the tooltip. But then again, maybe not.
