php - 使用 PHP 创建大写的 MySQL 表名

Question

我正在尝试使用此函数创建一个名为 ID1 的表:

public function createIDTable($IdNumber)
{
    $sql = "CREATE TABLE `Database`.`ID$IdNumber` (`Names` LONGTEXT CHARACTER SET latin1 COLLATE latin1_swedish_ci NOT NULL)";

        $query = mysql_query($sql)or die (mysql_error());
        return "Sucess";
}

它创建表，但名称始终是小写的，如 id1。我需要 ID1 - 我该怎么做？

如果您使用默认排序规则选项安装 SQL Server，您可能会发现以下查询返回相同的结果:

CREATE TABLE mytable 
( 
    mycolumn VARCHAR(10) 
) 
GO 

SET NOCOUNT ON 

INSERT mytable VALUES('Case') 
GO 

SELECT mycolumn FROM mytable WHERE mycolumn='Case' 
SELECT mycolumn FROM mytable WHERE mycolumn='caSE' 
SELECT mycolumn FROM mytable WHERE mycolumn='case'

您可以通过在列级别强制进行排序来更改查询:

SELECT myColumn FROM myTable  
    WHERE myColumn COLLATE Latin1_General_CS_AS = 'caSE' 

SELECT myColumn FROM myTable  
    WHERE myColumn COLLATE Latin1_General_CS_AS = 'case' 

SELECT myColumn FROM myTable  
    WHERE myColumn COLLATE Latin1_General_CS_AS = 'Case' 

-- if myColumn has an index, you will likely benefit by adding 
-- AND myColumn = 'case'
