包,我在其中声明了我的数据类型
create or replace package pkg_var is
type array_table is table of varchar2(50);
type array_int is table of number;
type p_arr_rec is record(p_no number,p_val varchar2(50));
type array_record is table of p_arr_rec;
end pkg_var;
/
我填充记录的过程
create or replace procedure proc1(p_array in pkg_var.array_table,
arr_int in pkg_var.array_int,len out number,arr_rec out
pkg_var.array_record)
as
v_count number;
begin
len := p_array.count;
v_count :=0;
for i in 1..p_array.count
loop
--dbms_output.put_line(p_array(i));
arr_rec(i).p_no := arr_int(i);
arr_rec(i).p_val := p_array(i);
v_count := v_count+1;
end loop;
end;
/
这是我class
调用上述程序将数组填充到记录表中
public class TestDatabase {
public static void passArray()
{
try{
dbcon conn = new dbcon();
Connection con = conn.dbstate().getConnection();
String str_array[] = {"one", "two", "three","four"};
int int_array[] = {1, 2, 4,8};
ArrayDescriptor str_des = ArrayDescriptor.createDescriptor("SCOTT.PKG_VAR.ARRAY_TABLE", con);
ARRAY arr_str = new ARRAY(str_des,con,str_array);
ArrayDescriptor des = ArrayDescriptor.createDescriptor("SCOTT.PKG_VAR.ARRAY_INT", con);
ARRAY arr_int = new ARRAY(des,con,int_array);
CallableStatement st = con.prepareCall("call SCOTT.proc1(?,?,?)");
// Passing an array to the procedure -
st.setArray(1, arr_str);
st.setArray(2, arr_int);
st.registerOutParameter(3, Types.INTEGER);
st.registerOutParameter(4,OracleTypes.ARRAY,"SCOTT.PKG_VAR.ARRAY_RECORD");
st.execute();
System.out.println("size : "+st.getInt(3));
// Retrieving array from the resultset of the procedure after execution -
ARRAY arr = ((OracleCallableStatement)st).getARRAY(4);
BigDecimal[] recievedArray = (BigDecimal[])(arr.getArray());
for(int i=0;i<recievedArray.length;i++)
System.out.println("element" + i + ":" + recievedArray[i] + "\n");
} catch(Exception e) {
System.out.println(e);
}
}
public static void main(String args[]){
passArray();
}
}
我得到了java.sql.SQLException: invalid name pattern: SCOTT.PKG_VAR.ARRAY_TABLE
异常,任何人都可以帮助我解决这个异常。
还有一个问题,如何检索SQL
in的记录表Java
?我的第二个问题是这个代码
ARRAY arr = ((OracleCallableStatement)st).getARRAY(4);
它是一个有效的代码table of record
吗?
