I wonder, is it possible to create sqlite3_value * from scratch
from within SQLite library's user code?
The idea is as follows. The current dbtriv.c [1] code has a
db_triv_exec_bound () function, used roughly as follows:
/* sqlite3 *db; */
const char *sql
= ("INSERT INTO foo (bar, baz)"
" VALUES ($1, $2);");
int r
= db_triv_exec_bound (db, sql,
SQLITE_INTEGER, (sqlite3_int64)1,
SQLITE3_TEXT, -1, "qux",
-1);
assert (r == SQLITE_OK);
This function will look up a cached prepared statement for the
SQL code passed, creating and caching one if none's found, and
then bind the parameters with sqlite3_bind_int64 (),
sqlite3_bind_text (), etc., matching the type specifiers passed.
Given some way to construct a sqlite3_value wrapping object, I
could instead rely on sqlite3_bind_value () alone, thus
eliminating the necessity of type specifiers in the interface.
TIA.
