jdbc调用oracle 函数，传到String返回CURSOR

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);
