请问有没有人用过getStrByclass()方法?
我在编写JSP代码时参照别人采用了一下这段代码:
"select distinct substr(tcidpk,0,"+String.valueOf(level*2)+") as tcidpk," +" getStrByClass(tcname,"+String.valueOf(level)+") as tcname " +" from tclassification where tcidpk like 'St%' ";
编译时出错:java.sql.SQLException: ORA-00904: "GETSTRBYCLASS": 无效的标识符 别人的程序能正常运行.我想问问大家谁用过GETSTRBYCLASS()这方法?
