Question

I have been at this for hours and MUST get this working! It is holding up an iPhone app release… My first time using SQLite. I have followed all the advice and yet my sqlite3_prepare_v2 call gets a SQLITE_ERROR (1) every time!

Here is my code from my controller:

        NSString *query = @"SELECT * FROM QandA ORDER BY random() LIMIT 1";
//  const char *sqlStatement = "SELECT * FROM QandA ORDER BY random() LIMIT 1";
    sqlite3_stmt *compiledStatement;

    // sqlite3_stmt *statement;
    int prepareStatus = sqlite3_prepare_v2(database, [query UTF8String],
                                           -1, &compiledStatement, NULL);
    if (prepareStatus == SQLITE_OK) {...

You’ll note that I’ve tried using a “char *” also to no avail (among other attempts). My database opens fine with:

    databaseName = @"Facts.sqlite";
// Get the path to the documents directory and append the databaseName
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
databasePath = [documentsDir stringByAppendingPathComponent:databaseName];
NSLog(@"databasePath = %@", databasePath);

int dbOpenStatus = sqlite3_open_v2([databasePath UTF8String], &database, SQLITE_OPEN_READWRITE, NULL);

From my controller interface:

    NSString *databaseName;
NSString *databasePath;

I’ve checked in the debugger and everything looks good, but the prepare statement fails. I don’t know how to log the statement it is trying to compile… I assume/hope it is just what my SELECT says.

Can anyone help? I’m desperate. Mark

Found the answer here. I had to use this instead for the path to the DB file:

[[NSBundle mainBundle]pathForResource:@"Facts"extension:@"sqlite"];

This gave a slightly different path (one extra directory) – once I used that it worked! Hope this helps someone else… I spent many hours on this.
