Good day,


I've been trying to work with SQL and an Access database in order to
handle custom user profiles. I haven't had any trouble reading from my
database, but inserting new entries into it has been troublesome to
say the least.

My ASP.NET script is supposed to execute an INSERT INTO statement in
order to add a user to the database. Here is a sample:

INSERT INTO LoginInfo (username, password, datafile) VALUES ('a',
'0cc175b9c0f1b6a831c399e269772661', 'H:\CommConn\userdata\a.xml')

This structure comes from http://www.w3schools.com/sql/sql_insert.asp

Everything seems valid, but ASP still throws an error stating that the
syntax of the statement is invalid. Could someone point out where the
'syntax' error is?

Try
INSERT INTO LoginInfo (username, password, datafile) VALUES ('a',
'0cc175b9c0f1b6a831c399e269772661',@ 'H:\CommConn\userdata\a.xml')

Notice the @ sign. "\" is an escape character. You have to use 2 '\'s if you
dont use the @ sign.

I was using Visual Basic, and did not believe that to be the problem.
I tried anyway, used the @ symbol. That didn't work, so I tried using
'\\' instead. Finally, I removed the last field altogether and had
just:

INSERT INTO LoginInfo (username, password) VALUES ('a',
'0cc175b9c0f1b6a831c399e269772661')

and the query still failed.

I'm totally lost now.

How are you executing this? C# or VB don't know anything about SQL commands.
You will have to use some sort of SqlCommand to send this sql-statement
to the database.

If this is not the problem, show some more code about how you are trying
to use it.

A few things. First, are you building the insert string? If so, are
you positive it's building the way you think it is?

Always try the sql statement in query analyzer to see if your SQL
statement is valid, or if you're building a poor SQL statement.

What error are you getting? Have you tried putting username and/or
password into [square brackets] in case they are reserved words? Is
the username field large enough for the size of the data you're trying
to put into it? Is there any validation on the database which is
rejecting your data for violating constraints, primary key etc?
 
It looks to me like it may be a data type exception, if the second column is
of SQL type uniqueidentifier, which is the same thing as a guid. The format
looks similar to the uniqueidentifier binary format, which would not have
single quotes around it. A uniqueidentifier value in a query should only
have single quotes around it when it is in the string format
'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'.
