tsql - problem with IN and LIKE in SQL when arguments contain special characters for a language -


I've got a key word table (MS SQL):

  • Keygide qualifier primary that
  • DA7E4E27-FDE5-4D43-A365-8A789164A816 tit kirkäna
  • EED58875-FE41-4A18-A93C-A44AA62CEEEE htit kirkänbh
  • A0EB795E-EE23-4990- BAB9 -897C93C70CE3 hit Kirknah
  • F7F4632B-AC82-4DEB-B966-BBA8EF4D2C9E step Kerknab
  • C0EB795E-EE23-4990-BAB9-897C93C70CE3 called Kirkns
  • E2F4632B-AC82-4DEB-B966-BBA8EF4D2C9E nam kirkänbs
  • A222795E-EE23-4990-BAB9-897C93C70CE3 tit kirkacb
  • B333632B-AC82-4DEB-B966-BBA8EF4D2C9E Tit kirkaca
  • 1222795E-EE23-4990-BAB9-897C93C70C81 htit kirkacbh
  • E533632B-AC82-4DEB-B966- BBA8EF4D2C82 htit kirkacah

This simple query returns all the relevant records correctly:

Select * From the key word where 'kirkan%' like ' Code>
  • DA7 A4E27-FDI-4 4D 43-A365-8A 789164A 816 Title Ridness
  • EED58875-FE41-4A18-A 9 3 C A44AA62 Siiiii HIT Kirkgb
  • A0EB795E-EE23-4990-BAB9-897C93C70CE3 Hate Kirknah
  • F7F4632B-AC82-4DEB-B966-BBA8EF4D2C9E step Krkanb
  • C0EB795E- EE23-4990-BAB9-897C93C70CE3 nam kirkänas
  • E2F4632B-AC82-4DEB-B966-BBA8EF4D2C9E nam kirkänbs

    I specific match To limit resutls, use such a query qualifier:

    Choose from key word * where qualifier in ('tit', 'hat') and primitive 'kirak%' < / Code>

    which works perfectly:

    • A222795E-EE23-4990-BAB9-897C93C70CE3 tit kirkacb
    • B333632B-AC82- 4DEB-B966-BBA8EF4D2C9E tit kirkaca
    • 1222795E-EE23- 4990-BAB9-897C93C70C81 htit kirkacbh
    • E533632B-AC82-4DEB-B966-BBA8EF4D2C82 htit kirkacah

    But when the phrase does not return it is a special character result:

    And with that it is not that the 'qualifier in' ('tit', 'hat') qualifiers in the keyword like this: 

      select * from the keyword where (Qualifier = 'tita' or 'qualify' = 'htit') and 'kirkän%' like PrimitiveKey;

    However it works like this:

    * Select * Where (like 'tit' or qualifier 'hat') like PrimitiveKey 'kirkän%' (qualifier like 'tit' or 'qualifier')
    • DA7E4E27-FDE5-4D43-A365-8A789164A816 tit kirkäna
    • EED58875-FE41-4A18-A93C-A44AA62CEEEE htit kirk nbh
    • A0EB795E-EE23-4990-BAB9 -897C93C70CE3 htit kirkänah
    • F7F4632B-AC82-4DEB-B966-BBA8EF4D2C9E tit kirkänb

    What What's wrong with the approach?

After "text" itemprop = "text">

Maybe you need to use Unicode compatible datatypes. Try declaring PrimitiveKey column as nvarchar, try by putting the string you want to match with an 'N' like this: Selection * from the keyword (like the qualifier 'htit' like 'tit' or the qualifier) ​​and like the PrimitiveKey% N'kirkän% '.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
