Question

我试图将Java String数组传递给PLSQL Stored-Procedure。经过大量的互联网搜索，我找到了一个对我不起作用的解决方案。首先，这里是我用PL / SQL表声明的包，名为＆＃34; CHAR_TABLE＆＃34;

包装：

create or replace PACKAGE MYPACKAGE IS 
TYPE CHAR_TABLE IS TABLE OF CHAR(06) INDEX BY BINARY_INTEGER;
PROCEDURE MYPROCEDURE(
    p_strings      CHAR_TABLE
);
END MYPACKAGE;

这是身体（也不重要）：创建或替换PACKAGE BODY MYPACKAGE是

  PROCEDURE MYPROCEDURE(
    p_strings      CHAR_TABLE
) AS
  BEGIN
    FOR i IN 1..p_strings.COUNT
    LOOP
      INSERT INTO myTable (s) VALUES (p_strings(i));
    END LOOP;
  END MYPROCEDURE;

END MYPACKAGE;

如果在互联网上找到的Java代码如下：

OracleCallableStatement stmt = (OracleCallableStatement)oracleConnection.prepareCall("{call MYPACKAGE.MYPROCEDURE(?)}");



    String[] data = { "one", "two", "three" };
    Array array = oracleConnection.createOracleArray("MYPACKAGE.CHAR_TABLE", data);

    stmt.setArray(1, array);
    stmt.execute();

    conn.commit();
    conn.close();

但问题是我得到以下异常：

Exception in thread "main" java.sql.SQLException: ORA-01403: no data found

ORA-06512: at "BERNHARD.MYPACKAGE", line 9
ORA-06512: at line 1

at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:5617)
at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:1385)

仅用于测试（查看对StoredProcedure的调用是否有效）我尝试了以下代码：

OracleCallableStatement stmt = (OracleCallableStatement)oracleConnection.prepareCall("        DECLARE var BERNHARD.MYPACKAGE.CHAR_TABLE;\n" +
                "BEGIN\n" +
                "\n" +
                "var(1) := 'a';\n" +
                "var(2) := 'b';\n" +
                "MYPACKAGE.MYPROCEDURE(var);\n" +
                "END;");
stmt.execute();

这很有效。但是我需要第一个将Java String Array绑定到Stored Procedure的输入参数的解决方案。我怎样才能做到这一点？或者我的错误是什么？

我猜测a-array（关联数组）是否来自java。它的索引从0开始。您可以尝试更改循环范围或更改循环类型。对于a-array，更合适的是while循环。检查示例。

declare 
 type CHAR_TABLE IS TABLE OF CHAR(06) INDEX BY BINARY_INTEGER;
 p_strings  CHAR_TABLE;
 idx BINARY_INTEGER;
begin 
 p_strings(0) := 'aaaa';
 p_strings(1) := 'bbbb';
 p_strings(2) := 'cccc';
 -- 1-st option
 FOR i IN 0..p_strings.last  loop
  dbms_output.put_line(p_strings(i));
 end loop;
 -- 2-nd option
 idx := p_strings.first;
 while idx is not null
 loop
  dbms_output.put_line(p_strings(idx));
  idx := p_strings.next(idx);
 end loop;

end;
