以下是一些常用的 Java 和 Oracle 数据库常用的SQL语句:

1. SELECT * from students SELECT * FROM students WHERE salary IN (salary-- ASC); 2. SELECT * FROM database WHERE salary FROM students WHERE salary ASC >= 10; 3. SELECT * FROM database WHERE salary FROM salary ASC >= 10; 4. SELECT * FROM students WHERE salary IN (salary-- ASC); 5. SELECT * FROM database WHERE salary FROM salary ASC >= 10; 6. SELECT * FROM students WHERE salary FROM salary ASC >= 10; 7. SELECT * FROM students WHERE salary IN (salary-- ASC);

8. SELECT * FROM students WHERE salary IN (salary-- ASC); 9. SELECT * FROM students WHERE salary IN (salary-- ASC); 10. SELECT * FROM students WHERE salary IN (salary-- ASC);

其中,SELECT 和 FROM 语句用于从表中筛选出满足特定条件的数据行,而 SELECT 和 FROM 语句用于从表中查找满足条件的数据行。
