使用数组作为查询参数
1、初始化数组参数的类型。
语句如下：

String[] arrayRuleNo = ruleNos.split(",");String C_ORACLE_VARCHAR = "TYP_AC_VARCHAR2";Connection conn = DaoUtil.getConnection(DaoTools.getConnName()).getMetaData().getConnection();ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor(C_ORACLE_VARCHAR, conn);ARRAY oraARRAY = new ARRAY(descriptor, conn, arrayRuleNo);

----------起始略-----------v_sql := 'SELECT a.query_no, a.NAME FROM Xxxx a WHERE a.query_no IN (';FOR i IN in_rulenos.FIRST .. in_rulenos.LASTLOOPv_sql := v_sql || in_rulenos(i) || ',';END LOOP;v_sql := substr(v_sql, 1, length(v_sql) - 1);v_sql := v_sql || ') ORDER BY a.query_no DESC';OPEN out_rules_name FOR v_sql;----------结束略-----------
