SQL 查询中的 Varchar 到数字转换错误，引用行带有简单的选择子句？

Question

我创建了一个相当复杂的选择查询，它在我的几个 Dynamics GP 数据库中按预期工作，但我遇到了一个数据库，它抛出以下错误

“消息 8114，级别 16，状态 5，第 36 行 将数据类型 varchar 转换为数字时出错。”

我没有在第 36 行转换任何内容，（双击错误将我带到该行）它的字面意思是： “选择不同的 a.CUSTNMBR 作为‘客户编号’，”

该特定列主要是 varchar 值（字母和数字），但有一些值完全是数字。我认为它们会被视为 varchar 吗？我假设引用的行实际上不是触发错误的地方。

此查询适用于其他数据库（具有基本相同的模式）的事实确实令人困惑。我从连接到多个系统表的自定义视图（我没有创建）中提取，作为每个数据库中的基础数据源。我想知道这种观点是否是问题所在？在这个特定的数据库上，视图会有所不同吗？我不确定如何追踪它。生成的创建脚本在每个数据库上完全相同。

下面是实际的查询脚本
