DBI綁定參數和方括號

Question

我在用下面的代碼的問題：

$sql = <<"END_SQL"; 
SELECT DISTINCT Matching.[CI M], Matching2_1.[LAC M], Matching2_1.[CI M], Matching.[Band M], Matching2_1.[Band M], Matching.Site, Matching2_1.Site, Matching.[BSC/RNC], Matching.[CellName M], Matching.[BSC/RNC M], Matching2_1.[CellName M] 
FROM Matching, [N 900 - 900], Matching AS Matching2_1 
WHERE Matching.[Band M]= ? AND Matching2_1.[Band M]= ? ; 
END_SQL 

$sth = $dbh->prepare($sql); 
$sth->execute(900, 900); 

列名包含空間，數據庫是MS接入所以我用方括號在查詢中使用它們

問題是，Perl將方括號解釋爲綁定參數，並且需要11個參數。

以下是錯誤：

DBD::ODBC::st execute failed: [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 11. (SQL-07002) at NEIGHBORS MAPPING.pl line 89.

Answer 1

Jet數據庫引擎也可以識別反引號爲表/字段分隔符，所以如果quare括號給你的麻煩，然後嘗試

SELECT DISTINCT Matching.`CI M`, ...
