我正在开发一个应用程序,我需要在其中将大量数据插入 sqlite 数据库。数据被正确插入,但问题是有时我得到一个例外
Assertion failure in -[AttendeeDetails addData:anddbpath:], /Users/abhisheknaidu/Desktop/EventApp/AttendeeDetails.m:118
2012-08-14 11:54:24.937 EventApp[3586:1770b]
* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error while creating add statement. 'SQL logic error or missing database''
这只会发生几次..
这里的任何人都可以帮我解决这个问题..
我使用下面的代码插入
- (void) addData:(NSMutableArray *)attendeeArray anddbpath:(NSString *)dbPath{
NSString *str = @"Not Available";
if(addStmt == nil) {
if (sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) {
const char *sql = "insert into AttendeeDetails(AtQRid , EventId , ImageUrl , FirstName , LastName , Company , Email , PhoneNumber , City , State , ATBarcodeID) Values(?,?,?,?,?,?,?,?,?,?,?)";
if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) != SQLITE_OK)
NSAssert1(0, @"Error while creating add statement. '%s'", sqlite3_errmsg(database));
}
sqlite3_bind_text(addStmt, 1, [[attendeeArray valueForKey:@"Attendee_QR_ID"] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(addStmt, 2, [[[[AppDelegate SharedInstance].DetailsOfEventArray valueForKey:@"Event_ID"] objectAtIndex:0] UTF8String], -1, SQLITE_TRANSIENT);
if ([attendeeArray valueForKey:@"Image_URL"] == [NSNull null]) {
sqlite3_bind_text(addStmt, 3, [str UTF8String], -1, SQLITE_TRANSIENT);
}
else {
sqlite3_bind_text(addStmt, 3, [[attendeeArray valueForKey:@"Image_URL"] UTF8String], -1, SQLITE_TRANSIENT);
}
sqlite3_bind_text(addStmt, 4, [[attendeeArray valueForKey:@"FirstName"] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(addStmt, 5, [[attendeeArray valueForKey:@"LastName"] UTF8String], -1, SQLITE_TRANSIENT);
if ([attendeeArray valueForKey:@"Company"] == [NSNull null]) {
sqlite3_bind_text(addStmt, 6, [str UTF8String], -1, SQLITE_TRANSIENT);
}
else {
sqlite3_bind_text(addStmt, 6, [[attendeeArray valueForKey:@"Company"] UTF8String], -1, SQLITE_TRANSIENT);
}
if ([attendeeArray valueForKey:@"Email"] == [NSNull null]) {
sqlite3_bind_text(addStmt, 7, [str UTF8String], -1, SQLITE_TRANSIENT);
}
else {
sqlite3_bind_text(addStmt, 7, [[attendeeArray valueForKey:@"Email"] UTF8String], -1, SQLITE_TRANSIENT);
}
if ([attendeeArray valueForKey:@"PhoneNo"] == [NSNull null]) {
sqlite3_bind_text(addStmt, 8, [str UTF8String], -1, SQLITE_TRANSIENT);
}

}

sqlite3_bind_text(addStmt, 10, [str UTF8String], -1, SQLITE_TRANSIENT);
}
else {
sqlite3_bind_text(addStmt, 10, [[attendeeArray valueForKey:@"State"] UTF8String], -1, SQLITE_TRANSIENT);
}
if ([attendeeArray valueForKey:@"State"] == [NSNull null]) {
sqlite3_bind_text(addStmt, 10, [str UTF8String], -1, SQLITE_TRANSIENT);
}
else {
sqlite3_bind_text(addStmt, 10, [[attendeeArray valueForKey:@"State"] UTF8String], -1, SQLITE_TRANSIENT);
}

}
if(SQLITE_DONE != sqlite3_step(addStmt))
NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database));
else
//SQLite provides a method to get the last primary key inserted by using sqlite3_last_insert_rowid
coffeeID = sqlite3_last_insert_rowid(database);
//Reset the add statement.
sqlite3_reset(addStmt);
}
addStmt = nil;
}
