全部是針對Microsoft SQL Server 2000的Stored Procedure的例子：
參照《iBATIS in Action》書寫：
1. max_in_example
Stored Procedure:
|
CREATE PROCEDURE [dbo].[max_in_example]
@a INTEGER = 0 OUTPUT,
@b INTEGER = 0 OUTPUT,
@c INTEGER = 0 OUTPUT
AS
BEGIN
IF (@a > @b)
SET @c = @a
ELSE
SET @c = @b
RETURN @c
END
GO
|
SqlMap:
|
<parameterMap id="pm_in_example" class="java.util.Map">
<parameter property="c" javaType="int" jdbcType="INTEGER"
mode="OUT" />
<parameter property="a" javaType="int" jdbcType="INTEGER" />
<parameter property="b" javaType="int" jdbcType="INTEGER" />
</parameterMap>
<procedure id="in_example" parameterMap="pm_in_example"
resultClass="int">
{ ? = call max_in_example(?, ?) }
</procedure>
|
Java Code:
|
publicstatic Integer getMax_in_example(int a, int b) throws SQLException {
Map<String, Integer> m = new HashMap<String, Integer>(2);
m.put("a", new Integer(a));
m.put("b", new Integer(b));
m.put("c", new Integer(0));
//執行存儲過程in_example
sqlMapper.queryForObject("in_example", m);
return m.get("c");
}
|
2. swap
Stored Procedure:
|
CREATE PROCEDURE [dbo].[swap]
@a INTEGER OUTPUT,
@b INTEGER OUTPUT
AS
BEGIN
DECLARE @temp INTEGER
SET @temp = @a
SET @a = @b
SET @b = @temp
END
GO
|
SqlMap:
|
<parameterMap id="swapProcedureMap" class="java.util.Map">
<parameter property="a" javaType="int" jdbcType="INTEGER"
mode="INOUT" />
<parameter property="b" javaType="int" jdbcType="INTEGER"
mode="INOUT" />
</parameterMap>
<procedure id="swapProcedure" parameterMap="swapProcedureMap">
{ call swap(?, ?) }
</procedure>
|
Java Code:
|
publicstatic Map swap(int a, int b) throws SQLException {
Map<String, Integer> m = new HashMap<String, Integer>(2);
m.put("a", new Integer(a));
m.put("b", new Integer(b));
//執行存儲過程swap
sqlMapper.queryForObject("swapProcedure", m);
return m;
}
|
3. maximum
Stored Procedure:
|
CREATE PROCEDURE [dbo].[maximum]
@a INT OUTPUT,
@b INT OUTPUT,
@c INT OUTPUT
AS
BEGIN
IF(@a > @b)
SET @c = @a
IF(@b >= @a)
SET @c = @b
END
GO
|
SqlMap:
|
<parameterMap id="maxOutProcedureMap" class="java.util.Map">
<parameter property="a" mode="IN" />
<parameter property="b" mode="IN" />
<parameter property="c" jdbcType="INTEGER" mode="OUT" />
</parameterMap>
<procedure id="maxOutProcedure"parameterMap="maxOutProcedureMap">
{ call maximum (?, ?, ?) }
</procedure>
|
Java Code:
|
publicstatic Integer maximum(int a, int b) throws SQLException {
Map<String, Integer> m = new HashMap<String, Integer>(2);
m.put("a", new Integer(a));
m.put("b", new Integer(b));
m.put("c", new Integer(0));
//執行存儲過程maximum
sqlMapper.queryForObject("maxOutProcedure", m);
return m.get("c");
}
|
以上的Java Code類方法都是寫在相應的ProcedureDAOImpl類中，可以通過ProcedureDAOImpl類調用相應得方法和傳入對應參數來與數據庫存儲過程交互。
注意：在SqlMap.xml文件中<parameterMap>中參數的順序跟<Procedure>中”?”的順序一致。
如：a, b, c; ? = procedurename(?, ?) 則，第一個問號表示a，依次類推。
