If I understand the question correctly, you have two separate problems, formatting and ordering.
What comes to formatting, if the data contains plain ANSI or unicode characters, then you should be fine with
TEXT[
^] datatype in the database as long as you use
SqliteParameter Class (Microsoft.Data.Sqlite) | Microsoft Docs[
^] correctly and define unicode
string
for
SqliteParameter.DbType Property (Microsoft.Data.Sqlite) | Microsoft Docs[
^].
If the data contains something more exotic such as pictures in binary format, I'd say BLOB would be the only way.
Then about the ordering. A select basically returns the data in 'random' order unless an
ORDER BY
clause is used, see
SQLite Query Language: SELECT[
^]
So to ensure that the data (rows) is returned in the same order as they were read, you need to have for example an integer column which you would increment every time a row is inserted. In general an autoincrement column should suffice if you insert the data in the correct order, see
SQLite Autoincrement[
^]
Of course for all the things to work you need to ensure that no formatting or ordering is lost while reading the data so you need to make sure that you use proper reader to read the ansi, unicode or binary data, which ever is the case.
