存在两个结构相同的数据库表T1(col1,col2,col3)、T2(col1,col2,col3),写出一SQL语句将所有T1数据导入到T2表()
A:select col1,col2,col3 from T1 into T2(col1,col2,col3)
B:insert T1 (col1,col,col3) into T2(col1,col2,col3)
C:insert into T2 (col1,col2,col3) as select col1,col2,col3 from T1
D:insert into T2(col1,col2,col3) select col1,col2,col3 from T1;
