/**
* SQLExecutor is a simple sql/jdbc utility class. SQL is supported with different format:
*
*
*
* All these kinds of SQLs can be generated by SQLBuilder conveniently. Parameters with format of Object[]/List parameters are supported for parameterized SQL({@code id = ?}).
* Parameters with format of Object[]/List/Map/Entity are supported for named parameterized SQL({@code id = :id}).
* DO NOT use primitive array {@code boolean[]/char[]/byte[]/short[]/int[]/long[]/float[]/double[]} for passing multiple parameters.
*
*
* Here is sample of CRUD(create/read/update/delete):
* ========================================================================
*
* ========================================================================
*
*
* If {@code conn} argument is null or not specified, {@code SQLExecutor} is responsible to get the connection from the
* internal {@code DataSource}, start and commit/roll back transaction for batch operations if needed, and close the
* connection finally. otherwise it's user's responsibility to do such jobs if {@code conn} is specified and not null.
*
*
* Transaction can be started:
*
*
* final SQLTransaction tran = sqlExecutor.beginTransaction(IsolationLevel.READ_COMMITTED);
*
* try {
* // sqlExecutor.insert(...);
* // sqlExecutor.update(...);
* // sqlExecutor.query(...);
*
* tran.commit();
* } finally {
* // The connection will be automatically closed after the transaction is committed or rolled back.
* tran.rollbackIfNotCommitted();
* }
*
*
*
*
* Spring Transaction is also supported and Integrated.
* If a method of this class is called where a Spring transaction is started with the {@code DataSource} inside this {@code SQLExecutor}, without {@code Connection} parameter specified,
* the {@code Connection} started the Spring Transaction will be used. Otherwise a {@code Connection} directly from the inside {@code DataSource}(Connection pool) will be borrowed and used.
*
*
* SQLExecutor is tread-safe.
