mybatis和ibatis插入oracle數據庫並返回主鍵id

一、假設

DB：Oracle

Table：PRODUCT

        Sequences：SEQ_PRODUCT

實體類：Product.java

二、demo

1、mybatis插入oracle返回主鍵id

<!-- mybatis插入oracle，返回id -->
<insert id="saveProductInfo" parameterType="Product" flushCache="true">
	insert into PRODUCT
	(
              id, pro_name, pro_price
	)
	values
	(
              SEQ_PRODUCT.nextval, #{proName}, #{proPrice}
	)
	<selectKey resultType="java.lang.Integer" keyProperty="id" order="AFTER">	
              select SEQ_PRODUCT.currval as id from dual
	</selectKey>
</insert>

2、ibatis插入oracle返回主鍵id

<!-- ibatis插入oracle，返回id -->
<insert id="saveProductInfo" parameterClass="com.test.Product" >
	<selectKey keyProperty="id" resultClass="int" type="pre">
             select SEQ_PRODUCT.nextval as id from dual
	</selectKey>
	insert into TB_CONCERT_LETTER
	(
            id, pro_name, pro_price 
	)
	values
	(
             #id#, #proName#, #proPrice#
	)
</insert>
