SqlCommand Parameter / Replace A Single Quote With Two Single Quotes

Oct 23, 2009

I use SqlParameters when executing database statements. I know that I can replace a single quote with two single quotes... but in the past SqlParameters took care of this for me. I have two projects.. in one, the SqlParameter does this and it handles single quotes fine, in another, it does not and I'm at a loss why (I even copied and pasted the code):

C# - Using SelectNodes With Attribute Having Single Quotes And Double Quotes?

Nov 9, 2011

Is there any way to use selectnode with the attribute having both single and double quotes? If we are having single quote in the attribute we can use like below,

nodeList = root.SelectNodes("//book[contains(title,""'attribute'"")]")

If we are having double quotes we can use,

nodeList = root.SelectNodes("//book[contains(title,'"""attribute"""')]")

how can I use an attribute ['attribute"] having both single and quotes in SelectNodes.

.net - Sql Parameters Appear To Not Add In The Single Quote For Strings

Oct 4, 2011

I have this block of code that sets up my sql parameters for a stored proc that does an insert.

Dim sproc As StoredProcedure = New StoredProcedure("UsersInsert2", DataAccessConfiguration)
sproc.AddInput("@ID", SqlDbType.NVarChar, 10, entity.UserId)
sproc.AddInput("@PCode", SqlDbType.SmallInt, entity.PriviledgeCode)
sproc.AddInput("@Pwd", SqlDbType.NVarChar, 10, entity.Password.ToString())

[code]...

I've tested the stored proc in SSMS and it works.The problem is when I try to call it from the application. it fails. the @@rowcount = -1. I've tried returning an error code from the db... no dice. keeps coming back as -1 what is going to get executed looks like this

sproc = {EXEC UsersInsert2 @ID=ruxtest7, @PCode=0, @Pwd=1234, @Lang=E, @Name=ruxpint, @Notice=1, @CreatedBy=ruxpint}

I've re-used this code several times. only difference being I'm using NVarChar and it's vb.net.

How To Escape Single Quote In String.Format

Jun 24, 2010

While searching on how to escape a single quote in String.Format, I found the answer at SO: Escaping single quote in String.Format(). It seems to be different for VB though. I tested it, and indeed C# needs

string s = DateTime.Now.ToString("MMM d \'yy 'at' H:mmm");
while VB needs
Dim s As String = Now.ToString("MMM d 'yy 'at' H:mmm")

Why does C# need a double backslash, and VB a single backslash? This might be a bit of a silly question to C# users, but while I can read C#, I'm not used to writing it.

Asp.net - Single Quote In LINQ Results Causing Error

Jul 14, 2011

I have the following LINQ query:

Dim find_id = From p In dbContext.Residents _
Where p.person_name = occupant _
Select p

I then pull the first returned ID like so:

Dim building_id As String = find_building_id.FirstOrDefault.id

This works fine, except with the person has a ' in their last name, like M'arta. In this case I get a NullReferenceException.

Okay, the problem appears to be that when I am capturing the name initially from a GridView it is inserting into the value a #39 instead of ' and then LINQ is keeping things correct, so I end up with a non-match since it is attempting to match:

M#38arta = M'arta

Convert Text With Single Quote To Upload To Oralce DB?

May 14, 2012

I have a function in VB.NET that runs a query from an MS SQL DB, puts the results into temporary variables, then updates an Oracle DB. My question is, if the string in the MS SQL contains a single quote ( ' ), how do I update the Oracle DB for something that has that single quote?

For example: Jim's request Will produce the following error: ORA-01756: quoted string not properly terminated The ueio_tmpALM_Comments (coming from MS SQL) is the culprit that may or may not contain the single quote.

update_oracle =
"update Schema.Table set ISSUE_ADDED_TO_ALM = '1'," & _
"ISSUE_COMMENTS = '" & ueio_tmpALM_Comments & "'," & _
"where ISSUE_SUMMARY = '" & ueio_tmpALM_Summary & "' "
Dim or_cmd_2 = New NetOracle.OracleCommand(update_oracle, OracleConn)
or_cmd_2.ExecuteNonQuery()

I have a string like "Hello'World" and a Data Table with some records in it. One of those records is "Hello'World".he problem is, when I do a .Select in the Data Table, it only tries to search for the "Hello" part and throws an error on "World" because it interprets the ' (single. cuote) like the closing cuote on sql.DataTable.select("text = 'Hello'World'")I have gone through msdn doc, and it says I can escape some characters with [] brackets or f.slashes , but I just can't figure out: .select("text = 'Hello[']world'")

.net - Remove Single Quotes From All Cells In A DataTable?

Apr 2, 2009

I have a table with many values inside of it that might have single quotes around them. I need to create a duplicate table without those single quotes. I can't modify the original table as I need to use it, 'as-is' later.

I've done this with a table.Clone and using a foreach to loop through the rows and columns removing single quotes as I need and then putting that new row into the new table. It works and it's straight forward.....but

I'd like to do the same thing using LINQ. This was my attempt....

Dim myResults = From myRow In dtTable _
From myItem In myRow.ItemArray _
Where TypeOf myItem Is String AndAlso _
myItem.ToString.StartsWith("'"c) AndAlso _
myItem.ToString.EndsWith("'"c)

I had trouble finding examples that weren't looking at a specific column in the DataRow. It looks like my code does pull back all the matching results - but I'm at a lose for how I can create a duplicate table/modify the values?

The only requirement is to not using a For Each; as I already know how to do that. I've gotten closer - but I still can't seem to create a new row or a new table.

My new approach hits a dead-end when I try to do this:

Dim MyNewRow As New Data.DataRow With {.ItemArray = myRemovedQuotes.ToArray}

The Error message I get says, "Error 1'System.Data.DataRow.Protected Friend Sub New(builder As System.Data.DataRowBuilder)' is not accessible in this context because it is 'Protected Friend'."

Adding Records To An Access Database Where The Data Contains Apostrophes (single Quotes)

Oct 5, 2011

The apostrophe is used to separate data when adding records to an Access Database data table using the "INSERT INTO" SQL statement. Having apostrophes in the data really screws things up with this new software. Is there a simple workaround? Is it possible to specify a different character? Is it possible to add data without using SQL Statements?

Querying A Single Column And Displaying All Results In A Single Textbox?

Sep 5, 2010

I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.

The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:

email0@address.com, email1@address.com, email2@address.com, etc, etc, ...

I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.

I am using Visual Basic 2010 and SQL Server 2005. I also have access to Visual Basic 2005 if needed.

Using A Single Picture Box To Display A Single Picture Form A Bank Of Pictures?

Mar 22, 2011

I have a few problems i need to solve. Firstly, I am looking for a piece of code i can use to display a picture from a bank of pictures. It will work on the basis of generating a random number and loading a picture that corresponds to that number. 

i.e. Dim RandNumber As Integer
Dim RandClass As New Random
RandNumber = RandClass.next(1, 10)
If RandNumber = 1 Then
Picturebox1.image = picture1

[Code]...

Secondly, can I then use subsequent picture boxes to display pictures from the same bank of images, without displaying the same image? Finally, I then need to be able to click the picture or a button beneath the picture to select it as an answer to a question and then the whole process starts again.

da.UpDateCommand.Parameters("@OrderID_New").Value = myTextBox.Text

And so on...My problem is how to supply the value of "paramete_Old" to be able to compare before update. I gues it has to do with obtaining the Original values of the rows based on RowVersion but I don't know how to effect it.

"SET OrderID = @OrderID_New, ProductID = @ProductID_New, " & _
"Quantity = @Quantity_New, UnitPrice = @UnitPrice_New " & _

Escape Double Quotes In As A Parameter To An NUnit TestCase?

The xml-node passed as the second parameter to the testcase is not valid however, as this clearly is not the correct way to escape double quotes. I'm sure I can find a workaround in order to check that the method under test returns the expected XML-node, but I'm curious:

Is there some clever way to pass a string such as this, containing double quotes, as a parameter to an NUnit test?
