I have next task.
There is PostgreSQL DB. With field like: id, mydata.
mydata - is binary blob. It can be 10MB or even more.
I need load all data from PostgreSQL to SQLLite.
I decided ti create struct that and fill it with data. And then
do INSERT operation in sqllite.
But I do not know is it's good way, and if it's ok what data
type should I use for blob (binary data).
struct MyData
{
string id;
string mydata; // what datatype I should use here??
}
MyData [] mydata;
MyData md;
while (rs.next())
{
md.id = to!string(rs.getString(1));
md.mydata = to!string(rs.getString(2)); //??
mydata ~= md;
}
....
stmtLite.executeUpdate(`insert into MySyncData(id,mydata)
values(md.id,md.data)`); //ddbc driver
is it's normal way to insert data?
Blobs are byte arrays, so they should be ubyte[]. They shouldn't
be strings, which are explicitly text only.
