I start a first session where I simulate an insert into a table t: session1>create table t (i int auto_increment primary key) Query OK, 0 rows affected (0,32 sec) session1>insert into t values() Query OK, 1 row affected (0,00 sec) session1>select * from t +-+ i +-+ 1 +-+ 1 row in set (0,00 sec) session1>start transaction Query OK, 0 rows affected (0,00 sec) session1>insert into t values() Query OK, 1 row affected (0,00 sec) I create a new session, session2, where autocommit is set to 0. JOOQ emulates the FOR UPDATE behaviour, by locking record by record with JDBC. The above example will produce a record-lock, locking the whole record for updates. SELECT * FROM BOOK WHERE ID = 3 FOR UPDATE.

How to insert a record into database using spring JDBC,insert sql query in spring, spring JDBC JdbcTemplate insert sql query example, spring jdbc insert example. So it would be possible that before running the select spring has raised a start transaction or it has already used the connection for running an another query. I try to make an hypothesis about the second question: Given the commit happens before the select (commit is at 14:16:06 and select is at 14:16:07) how is it that the select does not return the row inserted by the transaction? Transactions are managed by Spring.
I've enabled bin log as well as general log in mysql. The select runs after the insert and after the insert transaction has commited. Problem: An Insert happens inside a transaction and a select which reads the same data inserted does not see the data. The table is an InnoDB table and defaults like auto commit and isolation level repeatable-read is set. Context: The framework used is Spring and all queries are run with JdbcTemplate.
