Hi Xperts,
I am trying to insert some record using an Insert Into statement using command object in .net. First I am checking the availability of username using a dataset. If not available, then I am trying to insert the record into the table. But every time I am getting the following error:
Syntax error in INSERT INTO statement
I have a sample statement as:
INSERT INTO ForumMember (Title, FirstName, LastName, RegDate, Username, Password, Email, MemberStatus, IncludeSignature, NotifyDefault, PostCount, LastLoginDate, LastPostDate, Signature) VALUES ('Mr.', 'sankar', 'sengupta', '4/13/2004', 'sankar3', 'sankar3', 'sankar@csmworld.org', 3, 0, 0, 0, , , 'Mr. sankar sengupta')
I don't understand why this is happening. Here are my files:

Does the database folder have write permissions for the ASPNET user?

Hello,

You need to account for when the user enters text with a ' in it. This will throw off your SQL statement. Where you assume text may have this, you need to use the replace method to change ' into ''.

Brian

Hey,

You have two fields that aren't being passed anything, which appear as: ..., , , .... I don't think you can do that. You either have to not supply those fields in the INSERT INTO clause, or pass NULL into those fields, when doing dynamic SQL like that (..., NULL, NULL, ...).

Brian

Hi Brian, I've tried that (using NULL) also. The interresting part is the SQL Statement run okay when trying from the Access query builder utility, but generates this error when embeded in ASP.NET code. I am really confused. Must be some simple thing I am missing, not getting what it is.

Yes, the database folder is having the necessary permissions. Infact, I am able to enter data in one other page, but don't know what is happening in this case.
Sankar Sengupta

But in this particular case, I am not passing any single quote inside the SQL Statement, am I? So, this should work well... but this is not working also.
Sankar Sengupta

Hello,

How did you try putting in null? That should work because it's SQL that you are executing. I would think that the ", , " is still giving you problems. For testing sake, try hard-coding the values into the SQL string and execute that.

Brian

Actually, I believe the problem lies with one of the field names in the database table. Password is a reserved ODBC function call keyword, and thus using it as a field name in an INSERT INTO statement results in the error message you observed.

Avoid the problem by:

1. Renaming the field in the database and in the code.
--OR--
2. Surrounding the password field name in the INSERT statement with brackets, as in
strSQL = "INSERT INTO ForumMember (Title, FirstName, LastName, RegDate, Username, [Password], Email, ...

This is one reason why using a prefix naming convention is so practical. Prefacing every field name with something like 'fld' will help avoid other common reserved keywords, like First, Last, User, Password, Date, etc. For a complete list of keywords, you may want to http://msdn.microsoft.com/library/de...ra-rz_9oj7.asp

Yeah, I've seen that error before, I didn't even notice the field... Good catch.
