QSqlQuery and single quotes using bindValue

[Luc4]

Hi! I created some tables using sqlite with Qt. My problem is that I noticed that using bindValue this way:

query.prepare("INSERT INTO monitored_files "
                    "VALUES (NULL, :fileName, :original_relative_dir_path, :backupped_relative_dir_path, :directory_id)");
 query.bindValue(":fileName", entries.at(i));
 query.bindValue(":original_relative_dir_path", processRelativeDirPath);
 query.bindValue(":backupped_relative_dir_path", processRelativeDirPath);
 query.bindValue(":directory_id", directoryId);
 query.exec();

query.prepare("INSERT INTO monitored_files "
                    "VALUES (NULL, :fileName, :original_relative_dir_path, :backupped_relative_dir_path, :directory_id)");
 query.bindValue(":fileName", entries.at(i));
 query.bindValue(":original_relative_dir_path", processRelativeDirPath);
 query.bindValue(":backupped_relative_dir_path", processRelativeDirPath);
 query.bindValue(":directory_id", directoryId);
 query.exec();

To copy to clipboard, switch view to plain text mode 

where entries.at(i) is P9040479.JPG and processRelativeDirPath is "." (without "s), I get this when listing the records in sqlite:

1|'P9040479.JPG'|'.'|'.'|1

1|'P9040479.JPG'|'.'|'.'|1

To copy to clipboard, switch view to plain text mode 

this seems to be wrong as, if I write the query directly in sqlite:

insert into monitored_files values (null, 'P9040479.JPG', '.', '.', 1);

insert into monitored_files values (null, 'P9040479.JPG', '.', '.', 1);

To copy to clipboard, switch view to plain text mode 

I get:

2|P9040479.JPG|.|.|1

2|P9040479.JPG|.|.|1

The schema of my table is:

CREATE TABLE monitored_files (file_id INTEGER PRIMARY KEY,file_name VARCHAR(32767),original_relative_dir_path VARCHAR(32767),backupped_relative_dir_path VARCHAR(32767),directory_id INTEGER);

CREATE TABLE monitored_files (file_id INTEGER PRIMARY KEY,file_name VARCHAR(32767),original_relative_dir_path VARCHAR(32767),backupped_relative_dir_path VARCHAR(32767),directory_id INTEGER);

So it seems those Qt instructions are placing single quotes that shouldn't be there... My variables don't have those single quotes. Any idea where they come from?
Thanks!
