sql error ora-00907 missing right parenthesis create table
<p>I'm creating a table like this, </p>

<pre><code>CREATE TABLE ARTIST (

    ArtistID            Int             NOT NULL IDENTITY(1,1),
    LastName            Char(25)        NOT NULL,
    FirstName           Char(25)        NOT NULL, 
    Nationality         Char(30)        NULL,
    DateOfBirth         Numeric(4)      NULL, 
    DateDeceased        Numeric(4)      NULL,
    CONSTRAINT  ArtistPK            PRIMARY KEY(ArtistID),
    CONSTRAINT  ArtistAK1           UNIQUE(LastName, FirstName),    
    CONSTRAINT  BirthValuesCheck    CHECK (DateOfBirth &lt; DateDeceased),
    CONSTRAINT  ValidBirthYear      CHECK
            (DateOfBirth LIKE '[1-2][0-9][0-9][0-9]'),
    CONSTRAINT  ValidDeathYear      CHECK
            (DateDeceased LIKE '[1-2][0-9][0-9][0-9]')
);
</code></pre>

<p>and I get this error : </p>

<blockquote>
