iBatic调用与JAVA调用很类似,只是JAVA把参数的注册放到了类里面,而iBatis把参数的注册放到了XML配置文件里,下面两个例子,第一个是返回普通数据,第二个是返回游标。



1:返回普通数据



Map map = new HashMap();

map.put("username", "JACK");

sqlMapClient.queryForObject("pro_test",map);

System.out.println(map);

输出结果:

{o=NBA, ooo=1, oo=JACK, username=JACK}




<!--   存储过程 -->

<parameterMap class= "hashmap" id= "pro_map" >

<parameter property= "username" javaType= "String" jdbcType= "VARCHAR" mode= "INOUT" />

<parameter property= "o" javaType= "String" jdbcType= "VARCHAR" mode= "OUT" />

<parameter property= "ooo" javaType= "java.lang.Integer" jdbcType= "INTEGER" mode= "OUT" />

<parameter property= "oo" javaType= "String" jdbcType= "VARCHAR" mode= "OUT" />

</parameterMap>

<procedure id= "pro_test" parameterMap= "pro_map" >

{call user_account_proc(?,?,?,?)}

</procedure>




create or replace procedure user_account_proc

(

uname in out varchar,

ugroupname out varchar,

uid out number,

ugro out varchar

)

as

begin

select groupname,username,userid into ugroupname,ugro,uid from user_account where username = uname;

end;



2:返回一个游标



Map map1 = new HashMap();

sqlMapClient.queryForObject("pro_cursor",map1);

System.out.println(map1.get("backcursor"));

输出结果:

[

{userid=1, username=JACK, userpwd=BEIJING, groupname=NBA},

{userid=2, username=TOM, userpwd=SHANGHAI, groupname=NBA},

{userid=3, username=MARY, userpwd=SHANGHAI, groupname=IBM}

]




配置文件:

<resultMap class= "hashmap" id= "backmap" >

<result property= "userid" column= "USERID" />

<result property= "username" column= "USERNAME" />

<result property= "userpwd" column= "USERPWD" />

<result property= "groupname" column= "GROUPNAME" />

</resultMap>

<parameterMap class= "hashmap" id= "pro_cursor_map" >

<parameter property= "backcursor" javaType= "java.sql.ResultSet"

jdbcType= "ORACLECURSOR" mode= "OUT" resultMap= "backmap" />

</parameterMap>

<procedure id= "pro_cursor" parameterMap= "pro_cursor_map" >

{call user_account_proc1(?)}

</procedure>




过程:

create or replace procedure user_account_proc1

(

my_cursor out sys_refcursor

)

as

begin

open my_cursor for select * from user_account;

end;



另:ibatis调用oracle的函数,存储过程的方法 IN 和OUT /游标

1、对于全部是 in 类型的参数过程,采用下面的方法调用(ibatis版本是2.3)

比如过程:

Procedure Flashback_Op(v_table_owner Varchar2,v_table_name Varchar2,v_FlashbackScn   Number,v_xid Varchar2,v_dbid number);

调用方法:

<parameterMap id="tableDml_recycle" class="java.util.Map">

<parameter property="owner" jdbcType="varchar"

javaType="java.lang.String" mode=" IN " />

<parameter property="name" jdbcType="varchar"

javaType="java.lang.String" mode=" IN " />

<parameter property="scn" jdbcType="NUMBER"

javaType="java.math.BigDecimal" mode=" IN " />

<parameter property="dbId" jdbcType="NUMBER"

javaType="java.math.BigDecimal" mode=" IN " />

</parameterMap>

<procedure id="tableDml_zcRecycle" parameterMap="tableDml_recycle">

{call TassetREC.Flashback_Op(?,?,?,?,?)}

</procedure>

2、对于返回类型是 游标 (OUT)的函数,采用如下方式调用。

函数:

Function GetFirstPageNumRows(v_where varchar2,v_dbid Number,v_Numrows varchar2,v_queryid varchar2) return sys_refcursor ;

调用方式:

<parameterMap id="searchParam" class="java.util.Map">

<parameter property="result" jdbcType="ORACLECURSOR"

javaType="java.sql.ResultSet" mode=" OUT " resultMap="auditselect_resultList" />

<parameter property="ipAddress"

jdbcType="varchar" javaType="java.lang.String" mode="IN" />

<parameter property="dbId" jdbcType="NUMBER"

javaType="java.math.BigDecimal" mode="IN"/>

<parameter property="countNumber" jdbcType="NUMBER"

javaType="java.lang.Integer" mode="IN"/>

<parameter property="clientId" jdbcType="VARCHAR2"

javaType="java.lang.String" mode="IN"/>

</parameterMap>

<procedure id="firstPage" parameterMap="searchParam">

{ ? = call tlgadmin.GetFirstPageNumRows(?,?,?,?)}   (注意返回值在前面用?代表)

</procedure>

java代码这么取值:

@SuppressWarnings("unchecked")

public List getAuditSelectByPages(Map map) {

getSqlMapClientTemplate().queryForList("firstPage", map);//调用

List arryList = (ArrayList) map.get("result");//取值

return arryList;

}

3、对于返回值为一般数据类型的函数:

函数:

Function DeleteCommand(v_commandid Number,v_commandsetid Number default 0,v_dbid Number default 0) return Number ;

采用如下方式处理(把返回值当作出参来处理OUT):

<parameterMap id="CommandDeleteById" class="java.util.Map">

<parameter property="result" jdbcType="VARCHAR"

javaType="java.lang.String" mode="OUT" />

<parameter property="commandId" jdbcType="NUMBER"

javaType="java.lang.Integer" mode="IN" />

<parameter property="commandsetId" jdbcType="NUMBER"

javaType="java.lang.Integer" mode="IN" />

<parameter property="dbId" jdbcType="NUMBER"

javaType="java.math.BigDecimal" mode="IN" />

</parameterMap>

<procedure id="Command_deleteById"

parameterMap="CommandDeleteById">

{ ? = call truleadmin.DeleteCommand(?,?,?)}

</procedure>

java代码

this.getSqlMapClientTemplate().delete("Command_deleteById", map);

String num = (String) map.get("result");

return num;
