java存储过程数组

❶ oracle测试存储过程传入数组怎么传

这个是我自己写的一个例子，你看看：
在命令窗口执行以下语句，创建自定义类型NESTEDARRAY。
create or replace TYPE NESTEDARRAY IS TABLE OF NUMBER;

在存储过程中使用自定义类型NESTEDARRAY。
PROCEDURE GET_ARR_RESULT(INPUTARRAY IN NESTEDARRAY, AR OUT NESTEDARRAY) IS
BEGIN
AR := NESTEDARRAY();

FOR I IN 1 .. INPUTARRAY.COUNT LOOP
AR.EXTEND;
AR(I) := I|| INPUTARRAY(I);
END LOOP;
END GET_ARR_RESULT;

java代码：
import java.sql.Connection;
import java.sql.SQLException;

import oracle.jdbc.OracleCallableStatement;
import oracle.jdbc.OracleTypes;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
import oracle.sql.Datum;

/**
* Java获取Oracle存储过程返回自定义类型
* @author lucky star
*
*/
public class OracleTypeResultTest {

/**
* @param args
*/
public static void main(String[] args) {
Connection con = null;
OracleCallableStatement ocs = null;
String sql = "{call test.GET_ARR_RESULT(?,?)}";

try {
con = DBUtil.dbUtil.getConnection();
ocs = (OracleCallableStatement) con.prepareCall(sql);
String[] params = {“10001”,”10003”};
ArrayDescriptor arrayDesc = ArrayDescriptor.createDescriptor("NESTEDARRAY", con);
ARRAY inputArray = new ARRAY(arrayDesc, con, params);
ocs.setARRAY(1, inputArray);
ocs.registerOutParameter(2,OracleTypes.ARRAY,"NESTEDARRAY");
ocs.execute();

ARRAY array = ocs.getARRAY(2);
Datum[] datum = array.getOracleArray();
for (int i=0;i<datum.length;i++) {
System.out.println(datum[i].intValue());
}

} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
if(ocs!=null)ocs.close();
if(con!=null)con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

}

用VARCHAR2测试，发现存储过程中无法获取到传入的数组的值。
不过，将自定义类型由varchar2改成NVarchar2就成功了。

❷ JAVA调用存储过程，Oracle自定义类型作参数怎么写法

1. 存储过程以及类型定义如下：

--The array in oracle
CREATE OR REPLACE TYPE idArray AS TABLE OF VARCHAR2(20);

--package header
CREATE OR REPLACE PACKAGE Lib_Package AS
PROCEDURE Book_Check_Procere(ids IN idArray, exist OUT NUMBER);
END Lib_Package;

--package body
CREATE OR REPLACE PACKAGE BODY Lib_Package AS

PROCEDURE Book_Check_Procere( ids IN idArray, exist OUT NUMBER) AS v_Index BINARY_INTEGER; BEGIN v_Index:= ids.FIRST; LOOP SELECT COUNT(*) INTO exist FROM Lib_Duplicate WHERE status='Lent' AND book_id=ids(v_Index); EXIT WHEN v_Index=ids.LAST OR exist>0; v_Index:= ids.NEXT(v_Index); END LOOP;END Book_Check_Procere;
END Lib_Package;

2.在Java中调用上面的存储过程
(1) 在Oracle中定义数组类型idArray (2) 在java构造数组并转换成Oracle中定义的数组类型，调用存储过程

/** * 当要删除图书时，检查是否仍然有图书复本处于借出状态 */ public boolean checkBookStatus(String[] bookIds) throws DataAccessException {
boolean flag = false; Connection conn = null; OracleCallableStatement cstmt = null; ArrayDescriptor desc = null; ARRAY bookIdArray = null; int count = 0; String sql = "{call LIB_PACKAGE.Book_Check_Procere(?,?)}";
DbDriverManager dbManager = DbDriverManager.getInstance(); conn = dbManager.getConnection(Constants.DATABASE);
try { cstmt = (OracleCallableStatement) conn.prepareCall(sql);
//定义oracle中的数组类型 desc = ArrayDescriptor.createDescriptor("IDARRAY", conn); bookIdArray = new ARRAY(desc, conn, bookIds);
cstmt.setObject(1, bookIdArray, oracle.jdbc.OracleTypes.ARRAY); cstmt.registerOutParameter(2, Types.INTEGER); cstmt.execute(); count = cstmt.getInt(2);
log.info(this.getClass() + ".checkBookStatus: count = " + count);
DbOperHelp.closeStatement(this.getClass(), cstmt); DbOperHelp.closeConnection(this.getClass(), conn); } catch (SQLException e) {
log.error(this.getClass() + ".checkBookStatus-->SQLException: " + e.getMessage()); DbOperHelp.closeStatement(this.getClass(), cstmt); DbOperHelp.closeConnection(this.getClass(), conn); throw new DataAccessException( "When check the books, there is a SQLException: " + e.getMessage(), e.getCause()); }
if (count > 0) {
flag = true; }
return flag; }

❸ 在java中怎样删除所有存储过程

直接用jdbc执行sql语句块declare @procName varchar(500) declare cur cursor -- 定义个游标 for select [name] from sysobjects where type = 'p' open cur -- 打开游标 fetch next from cur into @procName --迭代游标并给@procName赋值 while @@fetch_status = 0 --判断迭代状态 begin if @procName <> 'DeleteAllProceres' exec('drop procere ' + @procName) -- 动态执行sql语句 fetch next from cur into @procName end close cur deallocate cur
