Update query syntax error

Question

4.00/5 (1 vote)

See more:

string query = "update DefaultProfile set Password='abc123' where RegNo='admin'";

can somebody please tell me what is the problem in the above query for an access database table.
table name : DefaultProfile

There are 4 columns in that table with the names: RegNo, Password, Course & Name.
I need to update the Password field but when I execute this query with an OledbCommand for access Connection, c# throws a syntax error for this update query.

I can't figure out what is the the problem in the syntax.

DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalization if you want to be taken seriously.

"Password" is a reserved word: you need to escape it:

C#

string query = "update DefaultProfile set [Password]='abc123' where RegNo='admin'";

But... don't do it like that!
1) Don't pass values to and database as strings, particularly if they may (as these will) originate with the user. Use Parameterised queries instead. passing strings as part of your SQL is an invitation to SQL injection attacks, which can damage or destroy your DB!
2) Never store passwords in clear text - it is a major security risk. There is some information on how to do it here: Password Storage: How to do it.[^]
