将空 sql 数组发送到 oracle 过程

Question

我正在尝试将 sql.Array 发送到过程中，但不知何故它在 oracle 过程中变空了。

我的 java 代码用数据填充 sql.Array 并尝试将其发送到程序中。

         oracle.jdbc.OracleConnection connection = (OracleConnection) JdbcConnection.getInstance().createConnection();
            String [] name = new String[]{"20206643799002684001","20206643799002684001"};
            ArrayDescriptor arrDec = ArrayDescriptor.createDescriptor("ARRAY_VARCHAR2",connection.unwrap(oracle.jdbc.OracleConnection.class));
            Array arr = new ARRAY(arrDec,connection.unwrap(oracle.jdbc.OracleConnection.class),name);
            OracleCallableStatement callableStatement = connection.prepareCall("{call bss_acc.ACC_STATEMENT(?,?,?,?)}");
            callableStatement.setDate(1,date);
            callableStatement.setDate(2,dateL);
           ((OracleCallableStatement)callableStatement).setARRAY(3,arr);
            callableStatement.setString(4,this.branchId);
            callableStatement.execute();

在程序中，我输入了日志，以便查看执行此程序后得到的值。在这个过程中，我总是得到空数组元素。

procedure ACC_STATEMENT
(
i_begin_date date,
i_end_date date,
i_ids array_varchar2,
i_mfo varchar2
)
is
o_ext_acc varchar2(20);
o_beginRest number;
o_endRest number;
o_name varchar2(100);
o_rest number;
o_type varchar2(100);

begin

FOR i IN 1.. i_ids.count LOOP
o_ext_acc := i_ids(i);

-- test

RAISE_ERROR(20000, 'o_ext_acc -' ||o_ext_acc);

我看到在用空 o_ext_acc 执行此错误后显示此消息我将其重定向到其他过程

java.sql.SQLException: ORA-20000:

UPD 当我进入调试模式以查看 arr 发生了什么时，我注意到这个 data.Which 意味着数组不从中获取值并且它显示问号而不是它。

UPD

我知道我正在使用 sql 数组并将其更改为 oracle。sql.Array 并尝试使用以下代码创建但它再次运行为空。

 oracle.jdbc.OracleConnection connection = (OracleConnection) JdbcConnection.getInstance().createConnection();
            String [] name = new String[]{"20206643799002684001","20206643799002684001"};
            oracle.sql.ARRAY a = connection.createARRAY("ARRAY_VARCHAR2",name);
            CallableStatement callableStatement = connection.prepareCall("{call bss_acc.ACC_STATEMENT(?,?,?,?)}");
            callableStatement.setDate(1,date);
            callableStatement.setDate(2,dateL);
           ((OracleCallableStatement)callableStatement).setArray(3,a);
            callableStatement.setString(4,this.branchId);
            callableStatement.execute();

UPD 3

        oracle.jdbc.OracleConnection connection = (OracleConnection) JdbcConnection.getInstance().createConnection();
        String [] name = new String[]{"20206643799002684001","20206643799002684001"};
        oracle.sql.ArrayDescriptor arrayDescriptor = new ArrayDescriptor("ARRAY_VARCHAR2",connection);
        oracle.sql.ARRAY a = new ARRAY(arrayDescriptor,connection,name);
        OracleCallableStatement callableStatement = (OracleCallableStatement) connection.prepareCall("{call bss_acc.ACC_STATEMENT(?,?,?,?)}");
        callableStatement.setDate(1,date);
        callableStatement.setDate(2,dateL);
        callableStatement.setARRAY(3,a);
        callableStatement.setString(4,this.branchId);
        callableStatement.execute();

UPD 4

发送空 oracle 后。sql.Array 它给出了我的程序和打印部分的错误，它显示为空 sql 数组元素

java.sql.SQLException: ORA-20000:

20000: o_ext_acc:/empty sending array element here is empty. Here should be element of sending array/ORA-06512: на "IBS.RAISE_ERROR", line 74 ORA-06512: на "IBS.BSS_ACC", line 30 ORA-06512: на line 1

UPD 5

我修改程序

FOR i IN 1.. i_ids.count LOOP o_ext_acc := i_ids(i);

-- test

RAISE_ERROR(20000, 'date:' || i_begin_date || 'accountElement ' || o_ext_acc);

然后我得到了以下错误，我可以看到日期但是有 空 o_ext_acc

java.sql.SQLException: ORA-20000: 20000: date:02.09.19accountElement

我无法在过程中发送 oracle.jdbc.Array 的问题它以某种方式从 jdbc 进入 oracle 过程，如空数组和元素为空

我运行来自 Oracle 的这个程序，它工作正常没有错误

Answer 1

使用oracle.sql.ARRAY和oracleConnection.setARRAY()而不是java.sql.Array和javaConnection.setArray()：

Connection connection = JdbcConnection.getInstance().createConnection();
OracleConnection oconnection = (OracleConnection) connection.unwrap( oracle.jdbc.OracleConnection.class );

String [] name = new String[]{"20206643799002684001","20206643799002684001"};
ArrayDescriptor arrDec = ArrayDescriptor.createDescriptor("ARRAY_VARCHAR2",oconnection);
ARRAY arr = new ARRAY(arrDec,oconnection,name);
/*
 * Or
 * ARRAY arr = oconnection.createARRAY("ARRAY_VARCHAR2", name);
 */
OracleCallableStatement callableStatement
  = (OracleCallableStatement) oconnection.prepareCall("{call bss_acc.ACC_STATEMENT(?,?,?,?)}");
callableStatement.setDate(1,date);
callableStatement.setDate(2,dateL);
callableStatement.setARRAY(3,arr);
callableStatement.setString(4,this.branchId);
callableStatement.execute();

Answer 2

经过两天的搜索主要问题是 datumnArray 是 ???。这意味着 oracld db 和 jdbc 与添加此代码的 characterset.After 不匹配。

 String s1 = new String(account.get(0).getBytes(), Charset.forName("ISO-8859-1"));
                String [] name = new String[]{s1};
                //oracle.sql.ArrayDescriptor arrayDescriptor = new ArrayDescriptor("ARRAY_VARCHAR2",connection);
                oracle.sql.ARRAY a = connection.createARRAY("ARRAY_VARCHAR2", name);

并将此库添加到 Maven

<dependency>
        <groupId>com.oracle</groupId>
        <artifactId>orai18n</artifactId>
        <version>11.1.0.7.0</version>
    </dependency>

这对我有用。我认为他们两个都对解决 problem.At 下图的开头起着至关重要的作用。
