Working with BDB SQL API (libsqlite3.a) on iPhone Simulator

Question

Hi,
I downloaded latest BDB and got a static library libsqlite3.a by compiling the code on Mac OS X (1.6.8 64bit).
I am now trying to use this library as a drop in replacement into a SQLite project.
I copied the SQLite database (with only one table) to a new Berkeley DB.
I want to access this new Berkeley DB with existing code using SQLite.
I followed following steps:
1. Added (copied) libsqlite3.a from build directory to my project
2. Added #import <db.h> and left #import <sqlite3.h> as it is
3. compiled the code and ran it in iPhone simulator
The code runs fine until I go to prepare a statement. Please see the snippet from the function below:
- (void)initializeDatabase {
NSMutableArray *todoArray =[[NSMutableArray alloc] init];
self.todos = todoArray;
[todoArray release];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"todo.db"];
if (sqlite3_open([path UTF8String], &database) == SQLITE_OK) {      // This is ok, opens berkeley DB
const char *sql = "SELECT pk FROM todo";
const char *tail;
sqlite3_stmt *statement;
if (sqlite3_prepare_v2(database, sql, -1, &statement, &tail) != SQLITE_OK) {    *// Fails here - table and records exist in Berkeley DB*
if (sqlite3_step(statement) == SQLITE_ROW) {
int primarykey = sqlite3_column_int(statement, 0);
Todo *td = [[Todo alloc] initWithPrimaryKey:primarykey database:database];
[todos addObject:td];
[td release];
} else {
NSAssert1(0, @"Failed to read from the table '%s'.", sqlite3_errmsg(database));
sqlite3_close(database);
sqlite3_finalize(statement);
} else {
NSAssert1(0, @"Failed to open database with message '%s'.", sqlite3_errmsg(database));
sqlite3_close(database);

Any thoughts?
