DBI绑定参数和方括号

Question

我在用下面的代码的问题：

$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); 

列名包含空间，数据库是MS接入所以我用方括号在查询中使用它们

问题是，Perl将方括号解释为绑定参数，并且需要11个参数。

以下是错误：

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数据库引擎也可以识别反引号为表/字段分隔符，所以如果quare括号给你的麻烦，然后尝试

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