使用Orchard.Projections模块,无法搜索Unicode文本。例如,结果查询为Select ... From ... Where ... Col Like '%term%'
,但我们希望在Select ... From ... Where ... Col Like N'%term%'
之后包含N
(Like
)。在代码中查找,我们在 Orchard.ContentManagement.HqlRestrictions 中找到public static BinaryExpression Like()
。通过添加N并将value = "'%" + FormatValue(value, false) + "%'";
更改为value = "N'%" + FormatValue(value, false) + "%'";
,我们会收到此错误:

有什么想法吗? 我们如何使用此模块在不更改数据库归类的情况下搜索unicode文本?
Orchard版本为1.8.1
答案 0 :(得分:0)
快速修复。我直接更改了数据库的整理设置
