CUBRID Q&A http://www.cubrid.org/?mid=questions CUBRID Q&A en Fri, 21 Oct 2011 02:37:10 -0800 Wed, 20 Mar 2013 22:07:09 -0800 XpressEngine 1.4.4.1 How can you get the transaction isolation level in CUBRID ? ovidiuv http://www.cubrid.org/questions/432359 http://www.cubrid.org/questions/432359 Hello,

I tried running the command "GET TRANSACTION ISOLATION LEVEL;" in CUBRID Manager and Python Driver. I followed the example below:

http://www.cubrid.org/manual/841/en/GET%20TRANSACTION%20ISOLATION%20LEVEL

Instead of getting the result, in Python Driver I obtained a "None" object, while in CUBRID Manager, the output was simply:

1'th SQL successfully executed.[0.446 second]
GET TRANSACTION ISOLATION LEVEL;

How can this command be ran correctly to obtain the isolation level ?

I checked now and in CSQL it works like this:

csql> GET TRANSACTION ISOLATION LEVEL;
=== <Result of GET ISOLATION LEVEL Command in Line 1> ===
       Result
=============
  REPEATABLE READ SCHEMA, READ UNCOMMITTED INSTANCES
Current transaction has been committed.
1 command(s) successfully processed.

However, I need it to work in Python Driver and CUBRID Manager also.

Best regards,

Ovidiu

cubrid lockdb demodb

But it locks the entire database.

I have already read Isolation Level related question and CUBRID Transaction and Lock guide.

But Isolation Level, as I understand, locks the table only during the transaction. But I have a series of transactions during which the table should not accept any UPDATE/INSERT/DELETE operations, including the time between these transactions.

What should I do to have the table locked until I manually unlock it?
