I have a fm file with around 70 tables populated with test data, I want to delete all the records so I can use it to import real data, wondering if there's a way to delete all records. There is a delete script but it can only do table by table.
Thanks in advance!
Why not simply save a copy of the file as clone (no records)?

I've generated a large table (1.1 million rows) in Postgres/PGAdmin that I'd like to export to CSV. When I click the "Save results to file (F8)" button, I get the "Downloading Results..." spinning wheel, and then the window letting me name the CSV and save it where I want on my computer. But once that CSV is on my computer it's empty. I've tried restarting PGAdmin and my computer but it's still happening.
Does anyone know why this is happening / how to fix? I would just copy/paste the table into a text file, but I think it's too large.
I couldn't find any prior questions about this.
Thanks.
I ran into the same problem. My solution was to create a table using your intended select statement.
Example:
CREATE TABLE query_results AS (
Select * from XXXX
)
Then, export the table to CSV.
My flow is simple and I am just reading a raw file into a SQL table.
At times the raw file contains data corresponding to existing records. I do not want to insert a new record in that case and would only want to update the existing record in the SQL table. The challenge is, there is a 'record creation date' column which I initialize at the time of record creation. The update operation overwrites that column too. I just want to avoid overwriting that column, while updating the other columns from the information coming from the raw file.
So far I am having no idea about how to do that. Could someone make a recommendation?
I defaulted the creation column to auto-populate in the SQL database itself. And I changed my flow to just update the remaining records. Talend job is now not touching that column. Problem solved.
Yet another reminder of 'Simplification is underrated'. :)
I have no Idea why records from a specific db table are getting automatic deleted. I have no PHP/code that delete the records
The table looks like this.

What should i look for to solve this?
Check that you did not update empty values into a column.. Or make sure you did not use "truncate table blah" in your scripts
Working on my first iOS App with SQLite database. In Project I have 2 Database, in which First Database is having only one table and the another one is working as a main database. I want to merge those databases into one (the Second one), by copy the table from first database to second database. The First database Table contains more than 32K records. So, I want to copy the entire table with Data.
I want to achieve this using SQLManager AddOn of firefox.
Any Idea?
Instead of SQLManager, You can simply do this with one command line:
$ echo '.dump tablename' | sqlite3 sourcedb | sqlite3 destdb
Export the required table contents in to an excel sheet in sqlite manager and then import the excel file in the target database.
you can see the controls for import and export in sqlite manager itself.
I hope this may help u, since I used it.
hai how to check the already existing records in sqlite3. I want to insert the parsed record from feed. it works but the issue is when i run the application twice record also stored in database twice. please give me the solution for my issue
Thanks in advance,
1.Try to check duplicate records before Inserting
or
2.Each and every record in sqlite has rowid which is unique one. so delete the duplicate record
by using rowid.
