table2(userid int,business int,func1 int,func2 int,func3 int)
table3(userid int,business int,app1 int,app2 int,app3 int,app4 int,app5 int,app6 int,app7 int,app8 int,app9 int)
table1的典型数据如下
business funcno appno
1 1 3
1 2 1
1 3 2
2 1 4
2 2 5
2 3 6
table2的典型数据如下
userid business func1 func2 func3
1 1 1 0 1
2 1 0 0 1
1 2 1 1 1
2 2 1 0 0
table3的典型数据如下
userid business app1 app2 app3 app4 app5 app6 app7 app8 app9
1 1 0 1 1 0 0 0 0 0 0
2 1 0 1 0 0 0 0 0 0 0
1 2 0 0 0 1 1 1 0 0 0
2 2 0 0 0 1 0 0 0 0 0
可以看到table3的数据实际是由table1和table2的数据生成的,table1是table2和table2之间的转换表,即由一个business和funcno可以确定一个appno,如table2表中的第一行数据,func1与business一起对应app3,func2与business一起对应app1,func3与business一起对应app2,因此在tabel3中userid为1,business为1的那一行对应的app1为0,app2为1,app3为1,由于business没有对应app4~app9,因此app4~app9全为0
现在table1和table2数据均存在,需要生成table3的数据,怎样使用存储过程高效实现?
