The 5'th parameter of sqlite3_exec() might be useful - it's error message in text format. The initial state of the database when the transaction was started is preserved. GORM optimizes many things to improve the performance, the default performance should be good for most applications, but there are still some tips for how to improve it for your application. In your case (executing inserts) callback isn't needed. You can replace your calls to sqlite3_prepare_v2(), sqlite3_step() and sqlite3_finalize() by single call to sqlite3_exec() and providing a callback function if it's more convenient. Notice that sqlite3_exec() also returns error code if any error occur. Int sqlRet = sqlite3_finalize(stmt) // sqlRet will contain error code I would try to move transaction's commit. To enable it, you’ll need to add the word COMPRESSION to a T-SQL backup query in the SQL Server Management Studio (SSMS) GUI. Different database implementations serve different needs and from the operational specs you provide, sqlite3 seems ideal for your needs. In this way, you obtain more security, more performance. 6 Answers Sorted by: 80 I try to avoid emotive replies and hyperbole but I am truly astonished at the lack of knowledge about sqlite displayed on this page. Step 1: The option to compress database backup is disabled by default. SQLite Transactions, Locking, and Cursors: explains how to work with transactions in an SQLite. You call it inside another sqlite3_prepare_v2() \ sqlite3_finalize() block and even if it's a legal operation, you commit transaction before all queries have been finished. How to speed up SQL backups through compression. What kind of error I did Thanks 1 Reply Last reply, 11:48 0 yuvaram, 09:35 Hi tham While working with database few steps need to be taken. Yes, it makes app smooth.Because SQLite consider one cursor as one transaction, so if we use begin transaction() before we insert big amount of data, then use setTransactionSuccessful() second, then endTransaction() in finally, SQLite will consider this insert event as one transaction, instead of hundreds of transactions. The second thing I want to mention here - sqlite3_exec() is a wrapper around sqlite3_prepare_v2(), sqlite3_step() and sqlite3_finalize(). Either with or without open transaction, insertion speed is very slow, it took more than 200 seconds to insert 37000 data. provide crash consistency, reduce complexity, and increase performance. Practically, you will club many SQLite queries. We show that when using TxFS transactions, SQLite performance on the TPC-C. It is important to control transactions to ensure data integrity and to handle database errors. SQLite is a Transactional DBMS while many INSERT statements are executed in close sequence, BEGIN TRANSACTION and COMMIT TRANSACTION. The SQLite project’s website describes it as a serverless database. Its transactions are ACID-compliant, even in cases where the system crashes or undergoes a power outage. For example, if you are creating, updating, or deleting a record from the table, then you are performing transaction on the table. SQLite is a self-contained, file-based, and fully open-source RDBMS known for its portability, reliability, and strong performance even in low-memory environments. So if there is any error, you will catch it and find its explanation in the official documentation. A transaction is the propagation of one or more changes to the database. I used the database insert method like this: database.insert(table, null, values) Īfter I also experienced some serious performance issues, the following code speeded my 500 inserts up from 14.I would check the return value of sqlite3_finalize() - it returns SQLITE_OK (which is equal 0) or an error code if any. Since the InsertHelper mentioned by Yuku and Brett is deprecated now (API level 17), it seems the right alternative recommended by Google is using SQLiteStatement. Try using a numeric timestamp instead of a date string and see how fast it is.
