如何使用EclipseLink调用Oracle存储过程
如何使用EclipseLink调用Oracle存储过程
提问于 2013-04-17 21:56:26
有人能解释一下如何使用EclipseLink调用存储过程吗？下面是我的存储过程：
TYPE nested_varchar2 IS TABLE OF varchar2(15);
TYPE nested_number IS TABLE OF number(1);
procedure set_pacs_state_cond(
icond in varchar2, -- where condition
icheck_state in number, -- check expected current state
iso_id_list out nested_varchar2, -- list of suboperators
ipac_list out nested_varchar2, -- list of pacs
iresult out nested_number -- list of results
);我使用EclipseLink 2.4.1作为JPA实现。请看我下面的代码。
PLSQLStoredProcedureCall call = new PLSQLStoredProcedureCall();
call.setProcedureName("PCK_PR.set_pacs_state_cond");
call.addNamedArgument("icond", "icond", Types.VARCHAR);
call.addNamedArgument("icheck_state", "icheck_state", Types.NUMERIC);
call.addNamedOutputArgument("iso_id_list", "iso_id_list", Types.ARRAY, "nested_varchar2");
call.addNamedOutputArgument("ipac_list", "ipac_list", Types.ARRAY, "nested_varchar2");
call.addNamedOutputArgument("iresult","iresult", Types.ARRAY, "nested_number");
DataModifyQuery valQuery = new DataModifyQuery();
valQuery.setCall(call);
valQuery.addArgument("icond");
valQuery.addArgument("icheck_state");
valQuery.addArgument("iso_id_list", java.sql.Array.class);
valQuery.addArgument("ipac_list", java.sql.Array.class);
valQuery.addArgument("iresult", java.sql.Array.class);
List test1 = new ArrayList();
List test2 = new ArrayList();
List test3 = new ArrayList();
valQuery.addArgumentValue("WHERE");
valQuery.addArgumentValue(1);
valQuery.addArgumentValue(test1);
valQuery.addArgumentValue(test2);
valQuery.addArgumentValue(test3);
session.executeQuery(valQuery);
List results = (List) session.executeQuery(valQuery);
em.getTransaction().commit();
DatabaseRecord record = (DatabaseRecord)results.get(0);
List ii = (List) record.get("iso_id_list");
List i = (List) record.get("ipac_list");
List r = (List) record.get("iresult");
em.close();我收到以下错误：
Internal Exception: java.sql.SQLException: ORA-06550: line 5, column 21:
PLS-00201: identifier 'ARRAY' must be declared
ORA-06550: line 5, column 21:回答 1

不能通过JDBC返回PLSQL表类型。PLSQLStoredProcedureCall的工作方式是用VARRAY类型包装表类型。您需要创建镜像VARRAY类型yourslef，并指定它们。以下是或测试之一的示例，
PLSQLCollection collection = new PLSQLCollection();
collection.setTypeName("PLSQL_P.PLSQL_CITY_LIST");
collection.setCompatibleType("PLSQL_P_PLSQL_CITY_LIST");
collection.setNestedType(JDBCTypes.VARCHAR_TYPE);
PLSQLStoredProcedureCall call = new PLSQLStoredProcedureCall();
call.setProcedureName("PLSQL_P.PLSQL_CITY_LIST_IN");
call.addNamedArgument("P_CITY_LIST", collection);
call.addNamedArgument("P_CITY", JDBCTypes.VARCHAR_TYPE);
DataModifyQuery query = new DataModifyQuery();
query.addArgument("P_CITY_LIST", java.sql.Array.class);
query.addArgument("P_CITY", String.class);
query.setCall(call);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
