string sn,c
select cno into :c from Shouke where tno=:sle_5.text;
select sno into :sn from Xuanke where cno=:c;
string s="select sno,ssex,sname,sage,dno from Student where sno=:sn"
dw_1.setsqlselect(s)
dw_1.retrieve()
因为c是主语言变量，却在sql server语句中···
select cno into :c from Shouke where tno=:sle_5.text;
select sno into :sn from Xuanke where cno=:c;
string s="select sno,ssex,sname,sage,dno from Student where sno=:sn"
dw_1.setsqlselect(s)
dw_1.retrieve()
因为c是主语言变量，却在sql server语句中···
select cno into :c from Shouke where tno=:sle_5.text;
c前面为什么有冒号
那要用字符串拼接 且值前后要有单引号
不太了解pb 不知道用什么语法拼接
string s="select sno,ssex,sname,sage,dno from Student where sno='"+:sn+"'"
