Secondly, storing plaintext passwords is a terrible thing to do. And just to point out a logic flaw: What if two users have the same password? Your current logic will change the password of every user that shares the original password. –Daniel Mann Jul 12 '14 at 3:57 In addition to those other issues, I'm not sure I understand why you're nesting your update inside the select. Your q1 is used only to test whether the user exists, but your update will already do that. This just ties up resources and acts as a huge waste of network. –Matthew Haugen Jul 12 '14 at 4:06 Also, this one is less serious, but why are you not making use of A

HansUp solved this syntax issues with in the update statement. What is happening now is completely different. process is user selects a gridview item it redirects them to the update page and using a datareader, fills the text boxes and check boxes based on the id passed http://stackoverflow.com/questions/6688139/update-query-syntax-error-in-asp-net-application in the url the user can then make their changes to the text boxes/ check boxes and then press the update button which runs the update query. what i have found is happening is that although a user might change the text, when they submit the changes, the update query is still using whatever was loaded into that text box by the data reader on the page load. Here is the code below: Protected Sub SubmitBTN_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateBTN.Click Dim tiresdim As Integer = 0 If TiresCHK.Checked = True Then tiresdim = -1 ElseIf TiresCHK.Checked = False Then tiresdim = 0 End If Dim repairs As Integer = 0 If RepairsCheckBX.Checked = True Then repairs = -1 ElseIf RepairsCheckBX.Checked = False Then repairs = 0 End If Dim onlotdim As Integer = 0 If OnLotCheckBX.Checked = True Then onlotdim = -1 ElseIf OnLotCheckBX.Checked = False Then onlotdim = 0 End If Dim offpropdim As Integer = 0 If OffPropertyCheckBX.Checked = True Then offpropdim = -1 ElseIf OffPropertyCheckBX.Checked = False Then offpropdim = 0 End If Dim soldim As Integer = 0 If SoldCheckBX

But I have read a post that you can put [password] like that and it will work. But its not working. I have tried syntax error in many ways and still, I hope that some one will help.

What's not working exactly? Any exception or error message? –yazanpro Apr 26 '15 at 3:44 As mentioned above, you should really change that to use parameters. Also, I believe you have an extra comma right before the "where" clause that could be causing a syntax error –Pablo Romeo Apr 26 '15 at 4:11 Welcome to Stack Overflow! I have edited your ti
MS Access Syntax Error messages 6 Comments 01 May 2008 11:06 3.91 (11 votes) ASP.NET 2.0 MS Access ADO.NET ASP.NET Web Forms This short article deals with the following common MS Access-related error messages: Syntax error (missing operator) in query expression 'field='some_partial_string' Syntax error in INSERT INTO statement Syntax error in UPDATE statement Syntax error in FROM clause Syntax error in WHERE clause There are 4 main causes for these errors: using a Reserved Word for a field name; embedded spaces in field or table names; attempting to insert unescaped single quotes; and incorrectly delimited datatypes. There is a fifth cause, and that is a genuine syntax error resulting from a typo, or otherwise misconstructed SQL statement. Assuming that you are sure this fifth cause is not applicable in your case, here's how to deal with the other four. Reserved Words and Embedded Spaces The most common culprits among reserved words are NAME and PASSWORD, which at first glance appear to be perfectly reasonable choices for field names in, say, a User table. What can be more confounding is that PASSWORD doesn't appear on this list of reserved words in Access. However, the fact is that in an ASP.NET application, you aren't dealing with an Access database. It's actually a Jet 4.0 database, and there is a separate list of reserved words for Jet 4.0 that does indeed include PASSWORD (but not NAME). Best advice is to familiarise yourself with both lists (and the one for Sql Server Reserved Words too) and avoid using any of them as a habit. However, if you can't change your field names, you will have to srround them with [ ] brackets: Select [name], [password], emailaddress From Users The same resolution applies to embedded spaces in field names: change them or surround them in [ ] brackets: Select [user name], userpassword, [email address] From Users When using the Query Builder within Visual Studio or Visual Web Developer, you will find that all field names are surrounded by brackets by default. Unescaped Single Quotes and Incorrect Datatype Delimiters The third and fourth causes of these errors will be totally resolved if you use parameters in your code. Single quotes act as string delimiters in Jet SQL, so when you try to pass a vlaue that contains a quote, such as a name like O'Brien, or a piece of text like "It's a lovely day", the Jet engine baulks and throws an error. It thinks that the apostrophe or single quote is telling it that the string value to be passed has ended, and anything afterwards should be treated as legitimate SQL. In the same way that single quotes delimit string values, other datatypes also have their own
