I am on ubuntu, i have Postgresql 13 installed on it. I have a file named (order.db) which is actually a database with a few tables in it. I want to import whole of (order.db) into postgres with same database name and of course the data. Is there any way to do it using terminal? any command?
The order.db file was created with the help of sqlite3 collaborating with c++. Order.db had nothing to do with postgresql at earlier phases of my project. I just want this (order.db) file to be imported as a database to my postgres.
I am using MAC OS. SQL Developer is not installed. Only zip file is in apolication folder. And when I click on the zip file, it extracts only one file - SQLDevelopr.exe. No others files or folders. Where do I find .conf file? And add my timezone?
I am using Oracle SQL Developer on MacOS and I am trying to save zip file into Blob field. I know how to load any other file type by clicking "Load" button and then selecting the file.
The problem is that when I select the zip file and click on Open, it does not select that file, but shows the me the content of zip file and then I can select only one file from that zip. This is not what I want, because I want to upload the whole zip.
Is there any setting in Oracle SQL Developer or any other way?
I do not have such problem on same table when using PLSQL Developer on Windows machine.
I have found out that when I have a zip file in a folder, then Oracle Sql Developer automatically shows also folders for this file, even if does not exist in reality on disk. The name of the folder and the file is the same including extension. Different is only the icon. If you select archive then loading to blob works ok. This is the behaviour on MacOS. I did not test it on other systems. On bottom picture is the example of folder containing only 2 zip files and how it looks when you try selecting file from that folder.
I have created the database for my Android app using SQLiteStudio 3.0.5 and now I need to save/export the one as .db file, but i found only the export to .sql-file. So, what should I do to make such procedure?
When you create database in SQLiteStudio it already is a proper sqlite database file. If you need to name it with .db extension, just rename the file in any file manager.
It sounds like you are trying to export the SQL command, and not the database itself.
Right-click on the database, and select "Export the database".
Hi I want to know how to copy files to HDFS from source file system(Local File system),if source file already copied to HDFS,then how to eliminate or ignore that file to copy again in HDFS using Talend.
Thanks
Venkat
To copy files from local file system to the HDFS, you need to use tHDFSPut components if you have Talend for big data. If you use Talend for data integration you can easily use tSystem component with the right command.
To avoid duplicated files, you need to create a table in a RDBMS and keep track of all copied files. Each time the job start copying file, it should check if it already exists in the table.
