jdbc调用oracle 函数，传入String返回CURSOR
create or replace function open_sql_cursor (v_sql varchar2) return sys_refcursor is c sys_refcursor; begin open c for v_sql; return c;end;JDBC调用代码
ResultSet rs1=null;CallableStatement call=null;String type="";String newSql ="{? = call asset.open_sql_cursor(?)}";try {conn = this.getDataSource().getConnection();call=conn.prepareCall(newSql);call.registerOutParameter(1, oracle.jdbc.OracleTypes.CURSOR);call.setString(2, sql);call.execute();//rs = ((OracleCallableStatement)call).getCursor(1);rs=(ResultSet)call.getObject(1);AuditInfo auditInfo;while(rs.next()){String errmsg = rs.getString("errmsg");Date loginTime = rs.getDate("loginTime");String dbUser = rs.getString("dbUser");String application = rs.getString("application"); 。。。。。。。。。。。 1函数是在asset账号下面 ，故有 String newSql ="{? = call asset.open_sql_cursor(?)}";
2传参，从左往右，依次为1 ，2.。。。。。。
3执行时使用 CallableStatement call=null;
prepareCall(newSql);
4取值有两种办法
rs = ((OracleCallableStatement)call).getCursor(1);rs=(ResultSet)call.getObject(1);
