Why Does My C# SQL INSERT Statement Get 'Incorrect Syntax Near 'User'' and How Can I Fix It?

SQL Error: Incorrect Syntax Near 'User'

When attempting to insert data into an SQL database using C#, users may encounter an error stating "Incorrect syntax near the keyword 'User'." This error occurs because "User" is a reserved keyword in SQL.

To resolve this issue, it is necessary to use square brackets to explicitly indicate that "User" refers to an object, rather than the keyword itself. The correct SQL statement should be:

INSERT INTO [User] (login, password, status) 
VALUES (@login, @password, @status)

By enclosing "User" in square brackets, the SQL interpreter recognizes it as an object and the insert operation can proceed successfully. It is important to note that this same principle applies to other reserved keywords in SQL, such as "Table," "Index," and "View."
