Oracle批量插入

别发呆了！！！2024-04-04 10:12

注意：与MySQL不同！

方式一

insert all into table(...) values(...) into table(...) values(...) select * from dual;

sql 复制代码

<insert id="addList" parameterType="java.util.List" useGeneratedKeys="false">
        INSERT ALL
        <foreach item="item" index="index" collection="list">
        INTO T_APPLAUD
        (
            ID,
            USER_ID,
            BUSINESS_TYPE,
            PRODUCT_ID,
            CREATE_TIME
        ) VALUES
        (
            #{item.id, jdbcType=NUMERIC},
            #{item.userId, jdbcType=VARCHAR},
            #{item.businessType, jdbcType=VARCHAR},
            #{item.productId, jdbcType=VARCHAR},
            #{item.createdTime, jdbcType=NUMERIC}
        )
        </foreach>
        SELECT 1 FROM DUAL
    </insert>

举例：

INSERT ALL

INTO tableName (column1, column2, column_n) VALUES (expr1, expr2, expr_n)

SELECT count(*) FROM dual;

【注】：查询语句"SELECT count(*) FROM dual;"不能少，需要一条查询语句，查询结果不重要。

方式二

insert into table(...) (select ... from dual) union all (select ... from dual)

sql 复制代码

<insert id="addList" parameterType="java.util.List" useGeneratedKeys="false">
        INSERT INTO T_APPLAUD
        (
            ID,
            USER_ID,
            BUSINESS_TYPE,
            PRODUCT_ID,
            CREATE_TIME
        )
        <foreach item="item" index="index" collection="list" separator="union all">
        (
            SELECT
                #{item.id},
                #{item.userId},
                #{item.businessType},
                #{item.productId},
                #{item.createdTime}
            FROM DUAL
        )
        </foreach>
    </insert>
