データベースに多くのレコードを挿入する必要がありますが、次のエラーが発生します。
Prepare-error library routine called out of sequence
これが私のコードです:
NSString *databaseName = @"DB.sqlite";
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *databasePath = [documentsDir stringByAppendingPathComponent:databaseName];
sqlite3 *concertsDB;
const char *dbpath = [databasePath UTF8String];
if (sqlite3_open(dbpath, &concertsDB) == SQLITE_OK)
{
sqlite3_exec(concertsDB, "BEGIN TRANSACTION", 0, 0, 0);
const char *sqlStatement = "INSERT INTO concertsData VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
sqlite3_stmt *compiledStatement;
if (sqlite3_prepare_v2(concertsDB, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
int hasError;
for (int i=0; i<[events count]; i++) {
sqlite3_bind_text(compiledStatement, 1, [[[events objectAtIndex:i] title] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_int(compiledStatement, 2, [[[events objectAtIndex:i] date] timeIntervalSince1970]);
sqlite3_bind_text(compiledStatement, 3, [[[events objectAtIndex:i] time] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 4, [[[events objectAtIndex:i] shortDesription] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 5, [[[events objectAtIndex:i] conductor] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 6, [[[events objectAtIndex:i] location] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 7, [[[events objectAtIndex:i] durations] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 8, [[[events objectAtIndex:i] works] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 9, [[[events objectAtIndex:i] solists] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 10, [[[events objectAtIndex:i] fulltext] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 11, [[[[events objectAtIndex:i] concertUrl] absoluteString] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 12, [[[[events objectAtIndex:i] buyUrl] absoluteString] UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(compiledStatement, 13, [[[events objectAtIndex:i] imageName] UTF8String], -1, SQLITE_TRANSIENT);
if (sqlite3_step(compiledStatement) != SQLITE_DONE) {
hasError=1;
NSLog(@"Prepare-error %s", sqlite3_errmsg(concertsDB));
}
sqlite3_clear_bindings(compiledStatement);
}
sqlite3_reset(compiledStatement);
if( hasError == 0 ) {
sqlite3_exec(concertsDB, "COMMIT", 0, 0, 0);
}
else {
sqlite3_exec(concertsDB, "ROLLBACK", 0, 0, 0);
}
}
sqlite3_close(concertsDB);
}
誰が何が間違っているのか教えてもらえますか?
