As you are submitting a string, simply switch to selection mode for:

sql.datatypes.integer[type].mysql

var sql = {
    datatypes: {

        integer:
        {
            INT: {
                mysql: 'INT'
            },
            SMALLINT: {
                mysql: 'SMALLINT'
            }
        }
    }
}

// Funciona
alert(sql.datatypes.integer.SMALLINT.mysql);

// Funciona também
teste("SMALLINT");
function teste(type){
     alert(sql.datatypes.integer[type].mysql);
}

To access an attribute with the key as a string you must use [] brackets:

sql.datatypes.integer[type].mysql
