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

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 a procedure in which I get values from different tables and calculate a certain decimal number. After that i try to post it on a form text-field which is a database item (update and insert allowed on the settings of block and item). everything works fine but the result wont show on the item and won't save in the database field. I get the error
"you cannot update this record".
Can someone help? i have been working on it for two days now and can't find anything.
Did you check if your user has update access on the table?
Check also if there are database triggers on the table that prevents you from updating the record.
Hopefully an easy question for someone with more experience than me. I have a stored procedure that Inserts records into a table. Like all databases that I have worked with, when you insert a record it inserts it into the bottom of the table. I would like to insert it to the top of the table and then move all the existing records down by one (I assume this would happen automatically with the insert).
I want to to do this because I'm using the 'Top #' keyword. I am pretty sure that I could just leave it the way it is, and instead of using the 'Top" keyword, I could use the 'Bottom" keyword. But I want to make it easier for people reading it that aren't familiar with it, so they can instantly see the newest entries. I'm going to keep researching this on my own, but If someone knew off the top of their head and could save me the time that would be appreciated.
is there any incremental id on that table.If yes then create clustered index on that id with descending order
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.
I'm quite new to iphone programming. I would like some information with you. Here is the structure of my database:
ID_song : auto-int (primary key)
txt_song : text
When we do delete some data from a table view, and when the data is deleted from the SQLite database, let's say I have only 3 songs in my database
id_song:1 txt_song:Song_A
id_song:2 txt_song:Song_B <------ (To be deleted)
id_song:3 txt_song:Song_C
After deleting the rows, does the data in the table looks like:
id_song:1 txt_song:Song_A
id_song:3 txt_song:Song_C
or
id_song:1 txt_song:Song_A
id_song:2 txt_song:Song_C
I mean, does sqlite reorganise the index?
Why would it do that ?
First of all, that could make a huge performance hit and a real risk to violate the integrity of the data.
Changing the primary key, means that all related foreign keys have to be changed as well.
No, it does not. (which you probably could've figured out in about 5 minutes by trying it yourself. :))
No. No Database will rewrite an ID field after deletion of a row. If you wish to number your songs, you will need to do this yourself in code.
it looks like
id_song:1 txt_song:Song_A
id_song:3 txt_song:Song_C
