My Problem database connectvity WARN: SQL Error: 0, SQLState: 08001 May 18, 2021 8:08:09 PM org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptions ERROR: No suitable driver found for I faced problem with database connectivity .I am using Eclispse Database 10g Tomcat 8.5 Ojdbc 14

My Code is hibernate.cfg.xml

I've got a PL/pgSQL function and I'm connecting to Postgres 12.x using Scala library called doobie which uses JDBC underneath. I'd like to understand if the whole call to the function will be treated as a single transaction? I've got default setting of autocommit.

The call to the function is simply:

select * from next_work_item();

My mysql version is 8.0. I have an InnoDB table with more than 10 million rows of data, and the data file size is 2G.

I am using pd.to_sql to insert several thousand rows of data each time. When the index is enabled, the insertion speed is very slow.

How to temporarily disable the index? And after the insertion is complete, enable the index?

I tried the operation in How to disable index in innodb:

I have two threads, they have to update the same table but the first one is using a primary key to lock a single record, the second thread have to lock a set of records using another index. The lock is made with SELECT ... FOR UPDATE steatment, I cannot understand why they run into a deadlock.

This is the table:

I am trying to delete an association object. It is deleted from the table but the parent object still has the child object in its collection. Here is my Code:

I need a simple ODBC test scenario on WIN which I can configure very simply and be assured it is working in support of another question at Unix.SE.

In a nutshell I'm trying to setup a PyODBC/Python script connection from Debian 10 (192.168.1.2) to Windows 10 in KVM/QEMU virtual system (192.168.1.12).

First, on the Windows 10/KVM, I see the ODBC Data Source Administrator has a tab File DSN and Microsoft Text Driver. Can I use FileDSN to test Python PyODBC connection to ODBC using a simple CSV file in place of Server?? (My research with ODBC only finds running server instances).

Next, what I tried:

• On Debian I installed ODBC Microsoft driver for Linux.

• Shutdown the Windows 10 firewall, and I can ping in both directions:

  $nmap -p 22 192.168.1.12 # Deb to Win

  > Test-NetConnection 192.168.1.2 -p 22 # Win to Deb

• On Windows 10/KVM I added a FileDSN with Microsoft Text Driver. I created a CSV file (odbc_test_01.csv) with simple header and one row of data (IE. {'ID' : 1, 'NAME' : 'FOO'})

• Created a Jupyter Notebook to make testing easier. Here is my connection string and the results:

  ...

I'm trying to attach some databases to a SQL server using a loop in Python. When executing the dynamic SQL string I'm getting the error below. The loop seems to be taking the header and feeding this as a variable into the dynamic SQL, as 'DATABASE' is a column header in the data frame. I want to take the first row of data from the data frame not the header. New to Python if it wasn't obvious.

ProgrammingError: ('42000', "[42000] [Microsoft][ODBC SQL Server Driver][SQL Server]A file activation error occurred. The physical file name 'Database' may be incorrect. Diagnose and correct additional errors, and retry the operation. (5105) (SQLExecDirectW)")

I have just copied a project and when I compile I have an error in my applicationContent.xml, when I put the mouse over the red='dataSource' within the bean 'entity' I got the error "Bean must be of 'javax.sql.DataSource' type, exception " and I am trying to find how to make it work, but I couldn't.

The log error says:

I am trying to use sqlalchemy-access library to insert a data frame into an access database:
