MySQL - How to check if START TRANSACTION is active

痞子三分冷 提交于 2019-12-05 05:21:31
I have noticed that START TRANSACTION automatically COMMIT the previous queries. Because of this and the fact that I have several stored procedure called before the end of the whole transaction, I need to check if I am inside a START TRANSACTION or not. Reading the manual I understood that autocommit is set to false inside a START TRANSACTION , but it doesn't seem like this. I have written the following procedure: CREATE DEFINER=`root`@`localhost` PROCEDURE `test_transaction`() BEGIN show session variables like 'autocommit'; start transaction; show session variables like 'autocommit'; COMMIT;

Problems with autocommit in sqlite3 module from Python3

I'm having trouble turning off the auto-commit mode in a given database connection. According to what I understood from the sqlite3 module documentation, the python code bellow should not raise any AssertionError exception, but it does. The table "nomes" already exists in the database and contains the column "Nome" import sqlite3 _PATH_DB = '/rhome/FNORO/tabelao/sofia.sqlite' # path to database _ISOLATION_LEVEL = "EXCLUSIVE" _TEST_NAME = "TEST1" # delete name from database with sqlite3.connect(_PATH_DB, isolation_level = _ISOLATION_LEVEL) as conn: query = 'DELETE FROM nomes WHERE nome = "{}"'

PHP: PGSQL driver and AutoCommit?

I use pg_connect, and pg_query in a project. But I'm really not sure that is pg_connect using AutoCommit mode or not? It is important question, because I need to write some block under transaction, and if one of the statements would be ignored by the server, the database would be inconsistent... Also interesting question that do pg_query a commit after execution? For example: pg_query('begin; update table1...; update table2...; commit'); is same as pg_query('begin;'); pg_query('update table1...;'); pg_query('update table2...;'); pg_query('commit'); and is the pg_query('begin; update table1...;

JDBC connection default autoCommit behavior

南楼画角 提交于 2019-12-03 23:50:43
I'm working with JDBC to connect to Oracle. I tested connection.setAutoCommit(false) vs connection.setAutoCommit(true) and the results were as expected. While by default connection is supposed to work as if autoCommit(true) [correct me if I'm wrong], but none of the records are being inserted till connection.commit() was called. Any advice regarding default behaviour? String insert = "INSERT INTO MONITOR (number, name,value) VALUES (?,?,?)"; conn = connection; //connection details avoided preparedStmtInsert = conn.prepareStatement(insert); preparedStmtInsert.execute(); conn.commit(); From

sqlite3 saving changes without commit command in python

久未见 提交于 2019-12-03 13:54:40
i read somewhere to save data to a sqlite3 database in python you got to call the commit() function on the connection object. i never do this but my database still gets the data saved to it... why? Auto-commit definition When auto-commit is on, it means that SQL transactions are: implicitly started by the SQL library (with a BEGIN statement) before data modification statements ( INSERT , UPDATE , DELETE or REPLACE ); explicitly ended by the user (with a COMMIT or ROLLBACK statement). When auto-commit is off, it means that SQL transactions are either: implicitly started by the SQL library (with

SolrJ: Disable Autocommit

南笙酒味 提交于 2019-12-02 17:49:19
问题 We have an instance of Solr, where we've found that turning on autoCommit in the solrconfig.xml actually may serve our needs well. However there are some instances and some batch operations where we want to temporarily disable autocommit. I have not been able to find anything, but I'm wondering if anyone knew if via SolrJ you could disable autocommit for a certain process, and then re-enable it? 回答1: You can't disable and enable autocommit as it's configured in solrconfig.xml. However, you

You can't disable and enable autocommit as it's configured in solrconfig.xml. However, you can leave it disabled in solrconfig.xml and use commitWithin for those add commands that need autocommit .

postgresql trigger: disable auto commit and set isolation level

蓝咒 提交于 2019-12-02 05:32:33
问题 i'm writing a trigger on database INSTEAD OF INSERT ON a table, that made some operation, then insert data into different related tables. Now i need to disable autocommit and set a different isolation level inside trigger, how can i do? 回答1: PostgreSQL doesn't have a setting that disables autocommit except for embedded SQL. If you try to set autocommit off in, say, PSQL, you'll see something like this error. sandbox=# set autocommit=off; ERROR: SET AUTOCOMMIT TO OFF is no longer supported
