Hello, I have three tables like this:
HomeDev(id,...,text)
ZPhDev(id,...,HomeDevId)
ZGroupItem(id,...,groupId,ZPhDevId)
Now, I want to get the items like this:
ZPhDev.id, and its corresponding HomeDev.text, the relation is like
this:
1. Get ZGroupItem.ZPhDevId When I know groupId
2. Get

firstly, so I don't know how to manipulate it? Just create a
index like this, or any more operation is needed?

Hello, how can I import an empty value into the database from a file.
The filed may be int or string, if I write "NULL" , then I'll read a
string "NULL" from it. I hope that I can get an empty value (Eg, an
empty string whose size() is zero in Qt).
How can I do ?
Thanks.

Hello, I'm a newbie for sqlite3, I hope somebody can tell me what's the
different of TEXT and VARCHAR. Does TEXT can save arbitrary characters,
but VARCHAR? Which is better, then?
Thanks.

Hello, community!
I want to create a new table, its primary key is an int 'id' column, but
I don't want to insert the data by hand, I hope the system can generate
it by adding id.
For example,
mytable(id, name, age)
When I insert name and age, the id is generated automatically.
And another
15 matches
