sqlite3_bind_text() not binding placeholders - c

Question

I am trying to use placeholder parameters as described in the sqlite documentation.
Below is the code I'm running.
No matter how I position the ? in the sql command, sqlite3_bind_text() doesn't work. I have also tried #table, :table, and ?1 as
placeholders. I even tried replacing the first two exec the calls with explicit prepare
and step calls.
What's interesting is that sqlite3_bind_int() works if I have a clause like:
sql = "SELECT * FROM test WHERE rowid = ?;";
Using sprintf() also works:
sprintf(sql, "SELECT %s FROM test;", "message");
/* gcc -l sqlite3 retrieve.c -o retrieve */

sqlite3 *db;
sqlite3_stmt *stmt;
int result;
const char *sql;
char *err_msg;
err_msg = 0;
result = sqlite3_open("test.db", &db);
if (result)
{
fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db));
sqlite3_close(db);
return(1);
}
sql = "CREATE TABLE IF NOT EXISTS test ("
"id INTEGER PRIMARY KEY,"
"message TEXT NOT NULL );";
result = sqlite3_exec(db, sql, NULL, 0, &err_msg);
if (result != SQLITE_OK)
{
fprintf(stderr, "SQL exec error: %s\n", err_msg);
sqlite3_free(err_msg);
}
sql = "INSERT INTO test (message) VALUES ('hi how ya doin');";
result = sqlite3_exec(db, sql, NULL, 0, &err_msg);
if (result != SQLITE_OK)
{
fprintf(stderr, "SQL exec error: %s\n", err_msg);
sqlite3_free(err_msg);
}
sql = "SELECT message FROM ?;"; /* doesn't work */
/* sql = "SELECT ? FROM test;"; /\* doesn't work *\/ */
result = sqlite3_prepare_v2(db, sql, -1, &stmt, NULL);
result = sqlite3_bind_text(stmt, 1, "test", -1, SQLITE_STATIC); /* doesn't work */
