Hello,
I found an issue in OrmLite with the StartsWith operator and unicode/utf8 characters. The Insert and Update methods works as expected, however when doing a Delete (I suspect that Select is affected too) with a StartsWith condition sends an Ascii text instead of a Unicode/UTF8 text.
It looks like there is a “N” missing in the generated SQL code: upper("Setting") like ''SOLR/SYNONYMS/EN-US/103B5145-F3C6-43F7-BFF9-9C7B9D7C2C80 動物あれこ/%''))'
It should be easy to add the missing “N” but I was wondering if this operation could be changed to use SQL parameters instead of using dynamic SQL to prevent SQL injection.
I included the relevant code below.
.Net code
db.DeleteAsync<Data.Configuration>(x => x.Scope == scope
&& x.Component == component
&& (x.Setting == setting || x.Setting.StartsWith(setting + BaseSettings.SettingDelimiter)));
Generated SQL (Sql Server)
exec sp_executesql N'DELETE FROM "Configuration" WHERE ((("Scope" = @0) AND ("Component" = @1)) AND (("Setting" = @2) OR upper("Setting") like ''SOLR/SYNONYMS/EN-US/103B5145-F3C6-43F7-BFF9-9C7B9D7C2C80 動物あれこ/%''))',N'@0 nvarchar(max) ,@1 nvarchar(max) ,@2 nvarchar(max) ',@0=N'All',@1=N'All',@2=N'Solr/Synonyms/en-US/103b5145-f3c6-43f7-bff9-9c7b9d7c2c80 動物あれこ'
