OraclePreparedStatementWrapper无法强制转换为java.sql.CallableStatement

Question

我试图通过java调用oracle db函数，如下所示：

StoredProcedureCall getTaxProcedureCall = new StoredProcedureCall();
getTaxProcedureCall.setProcedureName("getTaxByCustomerId");  
getTaxProcedureCall.addNamedArgument("ImpactedParty"); 
getTaxProcedureCall.addNamedArgument("ImpactedPartyType"); 


getTaxProcedureCall.addNamedOutputArgument("P_TAX");
getTaxProcedureCall.addNamedOutputArgument("A_TAX");

DataReadQuery query = new DataReadQuery();
query.setCall(getTaxProcedureCall);
query.addArgument("ImpactedParty");
query.addArgument("ImpactedPartyType");

Vector queryValues = new Vector();
queryValues.add(cusId);
queryValues.add("CSID");

Vector<DatabaseRecord> records = (Vector<DatabaseRecord>)TransactionContext.getCurrent().getUnitOfWork().executeQuery(query, queryValues);
return records;

但是当它运行时，它给出了：oracle.jdbc.driver.OraclePreparedStatementWrapper无法强制转换      到java.sql.CallableStatement

在Vector<DatabaseRecord> records = (Vector<DatabaseRecord>)TransactionContext.getCurrent().getUnitOfWork().executeQuery(query, queryValues);

Answer 1

我已将StoredProcedureCall替换为SQLCall

，从而解决了该问题

并传递sql字符串，如： SELECT getTaxByCustomerId(#ImpactedParty, #ImpactedPartyType, #TaxProfile) AS P_TAX FROM DUAL

现在它工作正常。
