Union is inefficient because it is scanned for duplicate values. If the merge does not intentionally delete duplicate rows, then use UNION ALL
Two the number of SQL statement fields to be joined must be the same, and the field type should be "compatible" (consistent);
If we need to display the results of the two SELECT statements as a whole, we need the union or UNION ALL keyword. The role of a Union (or union) is to combine multiple results together to display them.The difference between Union
The spatial position of two rectangles (2d) has four cases, as shown in the following figure:
To the two rectangle named a, a, but two rectangular sitting and lower-right coordinate (ax0,ay0), (bx0,by0), according to the judgment of four cases intersect there are four cases, that is, to write four judgments, this is a bit wordy, in fact, according to the four kinds of circumstances can be introduced by the law, as shown below:
This algorithm can be

You can use SQL to implement the same function, which is troublesome.
Drop table t1; drop table t2; create table t1 (id int primary key, nickname varchar (20), playNum varchar (20); create table t2 (id int primary key, nickname varchar (20),
You can use SQL to achieve the same functionality, which is a bit of a hassle.
drop table T1;
drop table T2;
CREATE TABLE t1 (ID int primary key,nickname varchar (), playnum varchar);
CREATE TABLE t2 (ID int primary key,nickname varchar
