SQL-02122 Invalid OPEN or PREPARE for this database connection
Cause
An attempt was made to execute an OPEN or a PREPARE statement using a cursor that is currently open for another database connection and, therefore, cannot be used for this connection.
Action
Close the cursor to make it available for this connection or use a different cursor for this connection.
EXEC SQL at :db_name prepare COUNTHR_SEL from :H_sql;
如果上面这句话出错，之后换个数据库连接再执行上面这句话，就会报02122错误，是什么问题？该如何解决？prepare没有close一说吧？
第一次查询如果出现table or view not exists这种错
第二次查询就会报 SQL-02122的错
