Subject: [PATCH 1/3] sqlite: Check that there are values to be set when
|
||||
binding
|
||||
|
||||
If the values vector is empty then we know already that the paramCount
|
||||
will still be invalid, so we should just accept that and not check the
|
||||
reused named placeholders.

Subject: [PATCH 2/3] sqlite: Bind duplicated named placeholders correctly
|
||||
|
||||
sqlite will reuse the index for bound parameters when the named
|
||||
placeholder is duplicated so we only need to call bind one time for each
|
||||
placeholder. Therefore we need to have just one instance of each value
|
||||
when doing the bind.

Subject: [PATCH 3/3] sqlite: Prevent a crash when sqlite does not detect any
|
||||
parameters
|
||||
|
||||
When using a virtual table inside a SQLite database it is possible that
|
||||
it does not report the right number of parameters. Therefore we need
|
||||
to account for this case to prevent it from crashing when trying to
|
||||
bind parameters it thinks does not exist.
