Android - 没有这样的归类序列：SQL_Latin1_General_CP1_CI_AS

Question

我正在开发一个Android应用程序，我需要使用下面的查询，

SELECT distinct AttributeValue.AttributeValueName as InventoryId
    ,WorkFlowTransaction.WorkFlowTransId
    ,Client.ClientName
    ,Project.ProjectName
    ,Product.ProductName 
FROM WorkFlowTransaction 
JOIN AttributeValue 
    ON WorkFlowTransaction.WorkflowTransId = AttributeValue.WorkflowTransId 
JOIN Attribute 
    on Attribute.AttributeId = AttributeValue.AttributeId 
JOIN Product 
    on Product.ProductId = WorkFlowTransaction.ProductId 
JOIN Client 
    ON Client.ClientID=WorkFlowTransaction.ClientId 
JOIN Project 
    on Project.ProjectID=WorkFlowTransaction.ProjectId 
where AttributeValue.AttributeValueName 
    COLLATE SQL_Latin1_General_CP1_CI_AS not in (
                                 Select LocationId 
                                 from BarcodeDetails 
                                             ) 
    and Attribute.AttributeName = 'Inventory Id'
    and WorkFlowTransaction.ClientId = 2 
    and WorkFlowTransaction.ProjectId = '44' 
    and WorkFlowTransaction.ProductId = '47' 
    and Attribute.IsDeleted ='0' 
    and AttributeValue.IsDeleted ='0' 
    and WorkFlowTransaction.IsDeleted = '0'

此查询在SQL-Server中运行良好。但在Android中抛出no such collation sequence: SQL_Latin1_General_CP1_CI_AS异常。
请帮助我提出您的想法或解决方案。

要了解整理顺序，请参阅此问题：What does 'COLLATE SQL_Latin1_General_CP1_CI_AS' do?

  

  
1. latin1使服务器使用charset latin 1处理字符串，基本上是ascii
  
2. CI不区分大小写的比较，因此'ABC'将等于'abc'
  
3. AS重音敏感，所以'ü'不等于'u'
  

在SQLite中没有直接替代它，Android SQLite不会公开安装自己的自定义归类序列所需的API。

根据您的数据和要求，您可以使用普通的COLLATE NOCASE与ASCII字符配合使用，但不能使用完整的Latin1字符集。
