发现一个SQL错误，我不知道该怎么办

-- 示例错误信息
ERROR: syntax error at or near "FROM"
LINE 2: SELECT * FORM users;

-- 错误的SQL
SELECT * FORM users;

-- 正确的SQL
SELECT * FROM users;

-- 错误的逻辑
SELECT * FROM users WHERE age > 'thirty';

-- 正确的逻辑
SELECT * FROM users WHERE age > 30;

-- 检查权限
SHOW GRANTS FOR current_user;

# 检查数据库服务状态
sudo systemctl status postgresql

-- 错误的数据类型
INSERT INTO users (id, name) VALUES ('1', 'Alice');

-- 正确的数据类型
INSERT INTO users (id, name) VALUES (1, 'Alice');

INSERT INTO orders (order_id, customer_id, order_date) VALUES ('101', 'C001', '2023-10-01');

ERROR: invalid input syntax for type integer: "C001"
LINE 1: INSERT INTO orders (order_id, customer_id, order_date) VALUES ...

-- 正确的SQL
INSERT INTO orders (order_id, customer_id, order_date) VALUES (101, 101, '2023-10-01');
