Question

我有一个加入BAccount表的BQL查询，但是当我查看SQL事件探查器时，它正在查询供应商表，我试图检索的对象不是供应商。这是我为SOLine表中的客户字段添加的自定义选择器。使用的所有字段和表都是基本的Acumatica字段和表。这是我的BQL代码：

[PXDBString(50, IsUnicode = true)]
[PXUIField(DisplayName = "Default Specification")]
[PXSelector(typeof(Search5<UploadFileRevision.comment, 
    InnerJoin<UploadFile, On<UploadFile.fileID, Equal<UploadFileRevision.fileID>>,
    InnerJoin<NoteDoc, On<NoteDoc.fileID, Equal<UploadFile.fileID>>,
    InnerJoin<BAccount, On<BAccount.noteID, Equal<NoteDoc.noteID>>,
    InnerJoin<Customer, On<Customer.bAccountID, Equal<BAccount.bAccountID>>
    >>>>, Where<Customer.bAccountID, Equal<Current<SOOrder.customerID>>>,
    Aggregate<GroupBy<UploadFileRevision.comment>>>),
typeof(UploadFileRevision.comment), typeof(UploadFile.name), 
typeof(UploadFile.fileID))]

代码在SQL事件探查器中转换为：

您可以看到，当它加入BAccount时，它使用[Vender] BAccount_Vendor，但我的BQL代码不包含任何涉及供应商的内容。我甚至在客户表中添加了冗余连接，但它什么也没做。我是否错过了强迫它查看BAccount表而不是供应商的内容？

Answer 1

尝试用BAccountR或BAccount2替换BAccount。在BAccount缓存之前，必须在BLC的Caches集合中为Vendor DAC初始化缓存 - 这通常会导致BQL转换为不同数据库表的SQL查询。

要检查初始化缓存的顺序，在VS中的立即窗口中，您可以为自定义BLC执行this.Caches或为BLC扩展执行Base.Caches。我很确定你会在BAccount之前初始化供应商缓存。

不幸的是，我尝试重现错误＆＃34;多部分标识符＆＃34; BAccount2.BAccountID＆＃34;无法受约束的＃34;没有成功。这是我在最后使用的自定义SOLine字段声明：

public class SOLineExt : PXCacheExtension<SOLine>
{
    public abstract class usrComment : IBqlField { }

    [PXDBString(50, IsUnicode = true)]
    [PXUIField(DisplayName = "Default Specification")]
    [PXSelector(
        typeof(Search5<UploadFileRevision.comment,
            InnerJoin<UploadFile, 
                On<UploadFile.fileID, Equal<UploadFileRevision.fileID>>,
            InnerJoin<NoteDoc, 
                On<NoteDoc.fileID, Equal<UploadFile.fileID>>,
            InnerJoin<BAccountR, 
                On<BAccountR.noteID, Equal<NoteDoc.noteID>>>>>,
            Where<BAccountR.bAccountID, Equal<Current<SOOrder.customerID>>>,
            Aggregate<GroupBy<UploadFileRevision.comment>>>),
    typeof(UploadFileRevision.comment), typeof(UploadFile.name),
    typeof(UploadFile.fileID))]
    public string UsrComment { get; set; }
}

查找似乎没有任何问题：

我错过了什么或做错了吗？

查询BAccount，但BQL正在查询供应商表而不是BAccount
