Re: [sqlite] System.Data.SQLite Field Name are surrounded by double quotes for Views
Joe, The problem is the following, I'm using and Orm Framework (ServiceStack.OrmLite namely). The query are generated, and double quoted are added automatically. There is now way to know if the query is on a View or a Table while generating the SQL. It definitely looks like a bug in SQLite to me. What do you think ?

The double quotes are coming from the SQLite core native library.
Run "sqlite3.exe :memory:" and execute the following commands:
.mode columns
.headers on
CREATE TABLE TEST (id);
CREATE VIEW TESTVIEW AS SELECT TEST.id FROM TEST;
INSERT INTO TEST (ID) VALUES('test');
SELECT "id" FROM "TEST"; -- Observe the results here.
SELECT "id" FROM "TESTVIEW"; -- Observe the results here.

[sqlite] System.Data.SQLite Field Name are surrounded by double quotes for Views
Hi all, It seems the IDataReader.GetName(int i) method return name surrounded by double quotes for views. Example: For a table : "Id" For a view : "\"Id\"" Is it the expected behaviour ? Thanks Vincent PS: In the same way, IDataReader.GetColumnIndex() will return -1 for view column name if you do not surround them with double quotes. ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
