SQL語句的正確寫法取決于具體的查詢或操作需求。以下是一些常見的SQL語句示例:
SELECT * FROM table_name;
SELECT column1, column2 FROM table_name;
SELECT * FROM table_name WHERE condition;
INSERT INTO table_name (column1, column2) VALUES (value1, value2);
UPDATE table_name SET column1 = value1, column2 = value2 WHERE condition;
DELETE FROM table_name WHERE condition;
SELECT table1.column1, table2.column2 FROM table1 INNER JOIN table2 ON table1.column3 = table2.column3;
請根據具體情況調整以上示例中的表名、字段名、條件和數值,以滿足您的需求。建議在編寫SQL語句時,先在數據庫管理工具或在線SQL編輯器中測試,確保語法正確并且符合預期結果。
