クエリのWHEREステートメントを@variableとして

Question

WHEREステートメントに変数を挿入するクエリがあります。

WHERE @Variable

私は（簡体字）、以下を試してみたが、動作するようには思えません。

注：ここでは、質問をする前に自分自身を理解するために連結要素を含めていません。

SET @id := x; 
SET @n := (SELECT COUNT(*) FROM Table2 WHERE id=@id); 
SET @Variable := (
(
Table1.Column1=(SELECT Column1 FROM Table2 WHERE id=@id LIMIT 1 OFFSET 0) 
AND Table1.Column2=(SELECT Column2 FROM Table2 WHERE id=@id LIMIT 1 OFFSET 0) 
AND Table1.Column3=(SELECT Column3 FROM Table2 WHERE id=@id LIMIT 1 OFFSET 0) 
) 
......... 
OR 
(
Table1.Column1=(SELECT Column1 FROM Table 2 WHERE id=@id LIMIT 1 OFFSET @n) 
AND Table1.Column2=(SELECT Column2 FROM Table2 WHERE id=@id LIMIT 1 OFFSET @n) 
AND Table1.Column3=(SELECT Column3 FROM Table2 WHERE id=@id LIMIT 1 OFFSET @n) 
) 
) 
; 


SELECT Table1.Column1, Table1.Column2, Table1.Column3, Table2.Column1, Table2.Column2, Table2.Column3 
FROM Table1, Table2 
WHERE 
@Variable 
; 

Answer 1

だからこの：

SET @IDNumber := 21; 
SELECT Players.PlayerID, COUNT(*) AS Games, SUM(Games.Points) 
FROM Teams, Players, Games 

WHERE 
Teams.PlayerID=Players.PlayerID 
AND 
Games.Game=Teams.Game 
AND 
Games.Team=Teams.Team 
AND 
Games.GameDate=Teams.GameDate 
AND 
(
Games.Game= ANY (SELECT Game FROM Teams WHERE PlayerID=@IDNumber) 
AND 
Games.Team= ANY (SELECT Team FROM Teams WHERE PlayerID=@IDNumber) 
AND 
Games.GameDate= ANY (SELECT GameDate FROM Teams WHERE PlayerID=@IDNumber) 
) 

GROUP BY Teams.PlayerID 
ORDER BY Games DESC 
; 

はこれを作成します。

私が探していたまさにです

+----------+-------+-------------------+ 
| PlayerID | Games | SUM(Games.Points) | 
+----------+-------+-------------------+ 
|  15 |  8 |    10 | 
|  21 |  8 |    10 | 
|  8 |  8 |    10 | 
|  14 |  6 |     7 | 
|  5 |  6 |     7 | 
|  19 |  5 |     6 | 
|  11 |  5 |     7 |

|  10 |  3 |     3 |
