Oracle和DB2的SQL数据库语法的区别（查询、插入、删除、更新）

在Oracle语句中的基本操作

//查询语法
SELECT column1, column2, ... FROM table_name WHERE condition;

//插入语法
INSERT INTO table_name(column1, column2, ...) VALUES(value1, value2, ...);

//删除语法
DELETE FROM table_name WHERE condition;

//更新语法
UPDATE table_name SET column1 = value1, column2 = value2 WHERE condition;

在DB2语句中的基本操作

//查询语法
SELECT column1, column2, ... FROM schema.table_name WHERE condition;

//插入语法
INSERT INTO schema.table_name(column1, column2, ...) VALUES(value1, value2, ...);

//删除语法
DELETE FROM schema.table_name WHERE condition;

//更新语法
UPDATE schema.table_name SET column1 = value1, column2 = value2 WHERE condition;
