JSON object into SQLite database

[moravas]

Hi Folks,

I have an SQLite database, where the last column has TEXT type. I would like to insert into that an JSON object which will not appear in the database after the execution of the query. To do that, I'm using this SQL statement:
@
insert or replace into issue (title, description, state, severity, attachment) values(?, ?, ?, ?, ?)
@
which is filled up by the following way:
@
QSqlQuery query(_database);
query.prepare(_session->value("card/sql/query/write/save").toString());
query.addBindValue(card.title);
query.addBindValue(card.description);
query.addBindValue(card.state);
query.addBindValue(card.severity);
query.addBindValue(card.attachment);
query.exec();
@

In my case the important is the last value adding: the card.attachment which is an QJsonObject instance.
After the executuion of the query, I tried to print out the errors too, everythings seem to be OK, but the cell in the databse is empty.

Can anybody help me?

Regards,
Norbert

Try this:

@query.prepare("insert into Bands (Description) values (:Description);");
query.bindValue(":Description", _session->value("card/sql/query/write/save").toString());
if (!query.exec()) {@

Maybe I haven't understood.
Haven't you got "card/sql/query/write/save" in the Description column?
Which kind of type Description field is?

Hi,

yes, maybe you misunderstood:

• Description column is a text type column in the database, but it doesn't have any matter.
• The important statement is the last two lines in my first post:
  ** I bind a JSon object into the prepared statement
  ** I execute the prepared statement query

The problem is that the result doesn't appear in the database.
