Question

我需要在java中执行程序PL sql。

我的PL / SQL。

TYPE REF_CURSOR IS REF CURSOR;
PROCEDURE GET_REPORT( P_account_number_param    IN VARCHAR2,
                      P_cycle_cut_param         IN VARCHAR2,
                      P_from_date_param         IN VARCHAR2,
                      P_to_date_param           IN VARCHAR2,
                      P_last_requested_by_param IN VARCHAR2,
                      P_worker_id_param         IN VARCHAR2,
                      P_requeset_type_param     IN VARCHAR2,
                      P_INQUIRY                 OUT REF_CURSOR,
                      P_RESULT                  out varchar2);

当我执行抛出错误rs = (ResultSet) cstmt.getObject(8);行
说明错误：列索引无效。供应商代码：17003

我尝试了多种方法来获得索引1,2或8但不起作用。

爪哇

CallableStatement cstmt = conn.prepareCall(sql);
int paramIdx = 1;
// pass IN parameter
if (params != null)
    for (int i = 0; i < params.length; i++) {
        cstmt.setString(paramIdx++, params[i]);
    }
// register result
cstmt.registerOutParameter(paramIdx++, OracleTypes.CURSOR);// index = 8
cstmt.registerOutParameter(paramIdx++, OracleTypes.VARCHAR);
cstmt.execute();
rs = (ResultSet) cstmt.getObject(8);
ResultSetMetaData md = rs.getMetaData();
int columns = md.getColumnCount();
results = new ArrayList<Map<String, Object>>();

这是我的PL / sql：

PROCEDURE GET__REPORT(P_account_number_param    IN VARCHAR2,
                                          P_cycle_cut_param         IN VARCHAR2,

请帮帮我谢谢你。

Answer 1

我见过“java.sql.SQLException：无效的列索引”主要是由于两个原因：

1) Setting column data using setXXXX(int coloumIndex) e.g. setInt(0) setString(0)
2) Getting column data using getXXX(int columnIndex) e.g. getInt(0) getString(0)

“java.sql.SQLException：无效列索引”的最常见原因是误认为列索引以“0”开头，如数组或字符串索引，但这不是真的，而是列索引以“1”开头，所以每当你尝试获取或设置列索引为“0”的列数据，您将得到“java.sql.SQLException：无效的列索引”。

检查是否要为各个索引分配params[i]。另外，请检查OUT方法中传递的getObject()参数索引。它应该是8或9。

如何从CallableStatement获取Object。（无效的列索引）
