oracle 存儲過程返回數組的方法：
1.建立包
create or replace package test is
TYPE filename_array IS TABLE OF varchar2(1);
filename filename_array;
end test;
2. 建立存儲過程
create or replace procedure test_array(v_cfjg out test.filename_array ) is
begin DECLARE i number;
D_cfjg dic_cfjg%rowTYPE;
-- D_nr dic_cfjg%rowTYPE;
cursor c1 is SELECT * FROM dic_cfjg;
BEGIN
i:=0;
v_cfjg := test.filename_array(); --數組初始化
open c1;
LOOP fetch c1 into D_cfjg;
EXIT WHEN c1%NOTFOUND ;
i:=i+1;
v_cfjg.EXTEND;
-- DBMS_OUTPUT.PUT_LINE(TO_CHAR(D_cfjg.dm));
v_cfjg(v_cfjg.count):=D_cfjg.dm;
DBMS_OUTPUT.PUT_LINE(v_cfjg(v_cfjg.count));
-- 測試
-- FETCH C1 INTO D_cfjg;
-- EXIT WHEN c1%NOTFOUND ;
END LOOP;
end;
EXCEPTION
WHEN TOO_MANY_ROWS THEN
DBMS_OUTPUT.PUT_LINE('TOO_MANY_ROWS');
WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE(sqlerrm);
end test_array;
===========================
Java 調用PL/SQL Returning Object Array
上次寫了oracle 存儲過程返回數組的方法。這次實現在java調用返回值是數組的存儲過程方法。
1. 數組：CYJ_ARRAY
CREATE OR REPLACE TYPE CYJ_ARRAY is VARRAY(20) OF integer
2. 存儲過程：getTestArray()
CREATE OR REPLACE FUNCTION getTestArray RETURN CYJ_ARRAY
AS
l_test CYJ_ARRAY :=CYJ_ARRAY();
begin
FOR i IN 1..10 LOOP
l_test.extend;
l_test(l_test.count) := i;
dbms_output.put_line(l_test(l_test.count));
END LOOP;
RETURN l_test;
END;
3. 調用存儲過程的java 類
public class TestOracleReturnArray {
public static void main(String[] args) throws SQLException {
Connection conn = null;
CallableStatement cstmt = null;
ResultSet rs = null;
try {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ora","zzz","sss");
conn.setAutoCommit(false);
String procedure = "{? = call getTestArray() }";// 調用存儲過程
cstmt = conn.prepareCall(procedure);
cstmt.registerOutParameter(1, OracleTypes.ARRAY,"CYJ_ARRAY"); //注：type name：區分大小，不是包中的type, 使用包中定義的type如何調用還不知道
cstmt.execute();
ARRAY array = (ARRAY)cstmt.getObject(1);
Object[] items = (Object[])array.getArray();
Object obj;
for (int i = 0; i < items.length; i++) {
obj = items[i];
System.out.println(obj);
} // for
} catch (Exception e) {
e.printStackTrace();
} finally {
//DbConnRestore.connRestore(rs, cstmt, null, conn);
}
}
}
