Question

I have two tables like indicated below:
Table1:

name    surname    age
----    -------    ---
 a         b       null
 c         d       null

Table 2:

age
---
 1 
 4

I want to combine them into first table (Table1) like

name    surname    age
----    -------    ---
 a         b        1
 c         d        4

(they have the same number of rows) How can I combine them?

Answer 1

maybe you want this,

SELECT a.Name, a.SurName, b.Age
FROM
  (
    SELECT @row := @row + 1 RankNo,
           Name, Surname
    FROM   Table1, (SELECT @row := 0) r
  ) a
  INNER JOIN
  (
    SELECT @row1 := @row1 + 1 RankNo,
           Age
    FROM   Table2, (SELECT @row1 := 0) r
  ) b ON a.RankNo = b.RankNo
