如何在不重命名表属性的情况下解决SQL名称冲突？

Question

I am trying to create a table (shown below) for my final year project, but I encountered SQL name conflict error. It seems the words 'User' and 'role' are reserved by the SQL. Is there any way I can resolve the issue, without renaming the words.

CREATE TABLE User
(
    ID INT generated by default as identity PRIMARY KEY,
    username varchar(45) NOT NULL,
    password varchar(255) NOT NULL,
    role varchar(255) NOT NULL
);

Answer 1

Throw square brackets around their name (or any reserved word that you want as your column names).

[User]

or

[Role]

Answer 2

Put double quotes around User. In general it never hurts to quote all your identifiers.

Answer 3

Try this is you are using SQL Server(in MySql it can be done using backticks ``):

CREATE TABLE [User]
(
    ID INT generated by default as identity PRIMARY KEY,
    username varchar(45) NOT NULL,
    password varchar(255) NOT NULL,
    [role] varchar(255) NOT NULL
);

On a side note:- It is not recommended to use reserved keywords for tabe name and column names.

Use some other names like Users and Roles which are not reserved keyword and which have a similar namings.

EDIT:

After looking at your comments it looks like you are using Derby. So you need to use double quotes.

Try this:

CREATE TABLE "User"
(
    ID INT generated by default as identity PRIMARY KEY,
    username varchar(45) NOT NULL,
    password varchar(255) NOT NULL,
    "role" varchar(255) NOT NULL
);
