Hello,
I am using SQLite 3.3.8 library on Mac OS X using XCode 2.4.1 (gcc
4.0)...
I try to compile only once an SQL instruction like "INSERT INTO Book
(author_fk,title,date,time,price,created) VALUES (?,?,?,?,?,?);" and
insert multiple rows through a (sqlite3_bind_xxx / sqlite3_bind_step)
loop but I everytime got errors...
Does looping through step is only available for "SELECT" ? Cannot we
think that a compiled SQL statement could be reuse many times as long
as only the bindings change ?
I try to use "sqlite3_reset()" and/or "sqlite3_clear_bindings()"
before "re-binds" and "re-step" but I always get an error 21
(SQLITE_MISUSE) when I am calling them on a already used sqlite3_stmt...
Here is a summary of what I try to do:
sqlite3_prepare
// insert first row
sqlite3_reset()
sqlite3_clear_bindings()
sqlite3_bind_xxx()
sqlite3_bind_xxx()
...
sqlite3_bind_xxx()
sqlite3_step
// insert second row
sqlite3_reset()
sqlite3_clear_bindings()
sqlite3_bind_xxx()
sqlite3_bind_xxx()
...
sqlite3_bind_xxx()
sqlite3_step
etc...
I do not know why functions like "sqlite3_reset()" and
"sqlite3_clear_bindings()" exist if it is not for doing this ?

Luc Demarche
