I have access to the database using postgreSQL. There are over 300 tables to look through, and I can't seem to find where to get the project name for a query I want to run. In 'project_task' there is a 'task_name' field. In 'project_phase' there is a 'phase_name' field. But in 'project_project' there doesn't seem to be a 'project_name' field. Seems a bit odd.
project_project does not have a name field. Instead it uses inheritance at the ORM level to get a name from account_analytic_account.
Using SQL, your query will need to join project_project to account_analytic_account using analytic_account_id and get the name field off that table.

As you see, it's Database name to filter. There's just few databases. So no need to filter 'Database name`. I need to change it to 'Table name to filter'. But it seems there's no option for it.
Weird thing is, it was a 'Database name to filter' at the time of first installation. I don't know when and how it changed.
Just re-installed it and it's done :(
I am using mongodb and odata.
I want to select name field alone for particular user id. (i.e) select name from userdata where userid=1;
/*my collection schema - userdata*/
{
id:number,
userid:string,
name:string,
data:object
}
I tried http://localhost:27017/userdata?$format=json&$filter=userid eq '1'&$select=name
Instead of getting name file alone I got whole object/document that matches userid=1. What I am doing wrong here?
I spoted the problem after the comment from #jps.
The issue is not with query, the problem is with data model which I am using is mismatching with my database schema (i.e) I missed out name field in model, so it is returning whole collection.
Now model is fixed, so the service is responding back with names for given userid.
I have a list of tables in an Oracle Schema. I use SQL Developer to build my queries. I can click on each table within the schema in SQL Developer and get access to a number of tabs, one of which is 'Details':
Within the 'Details' window, I have a property called 'Comments' which contains a description of what the table is for.
Now, I have quite a few tables and I want to somehow grab the table name and description in that comments property for each table and put it into a spreadsheet. Is there any way to do that in SQL Developer? Maybe a query? Or some built in function that iterates over each table and provides that information? I thought about using python, but I'm not sure I can access the 'Details' of the table.
Every once in a while, I find a solution before i have some of you awesome people answer for me, so i thought I'd post up what I found. This is the query I found that works:
select * from all_tab_comments where owner = 'your_schema_name_here'
This provides a list of all the tables in the schema (owner) I want and provides the comments I was looking for. From there, I can just export to an excel spreadsheet.
As far as I can tell, the search filter in the navigator will only search available database names, not table names.
If you click on a table name and start typing, it appears that a simple search can be performed beginning with the first letter of the tables.
I'm looking for way to be able to search all table names in a selected database. Sometimes there can be a lot of tables to sort through. It seems like a feature that would likely be there and I can't find it.
Found out the answer...
If you type for example *.test_table or the schema name instead of the asterisk it will filter them. The key is that the schema/database must be specified in the search query. The asterisk notation works with the table names as well. For example *.*test* will filter any table in any schema with test anywhere in the table name.
You can use the command
SHOW TABLES like '%%';
To have it always in your tools, you can add it as a snippet to SQL aditions panel on the right.
Then you can always either bring it in your editor and type your search key between %%, or just execute it as it is (It will fetch all the tables of the database) and then just filter using the "filter rows" input of the result set.
I'm interested in using the following audit mechanism in an existing PostgreSQL database.
http://wiki.postgresql.org/wiki/Audit_trigger
but, would like (if possible) to make one modification. I would also like to log the primary_key's value where it could be queried later. So, I would like to add a field named something like "record_id" to the "logged_actions" table. The problem is that every table in the existing database has a different primary key fieldname. The good news is that the database has a very consistent naming convention. It's always, _id. So, if a table was named "employee", the primary key is "employee_id".
Is there anyway to do this? basically, I need something like OLD.FieldByName(x) or OLD[x] to get value out of the id field to put into the record_id field in the new audit record.
I do understand that I could just create a separate, custom trigger for each table that I want to keep track of, but it would be nice to have it be generic.
edit: I also understand that the key value does get logged in either the old/new data fields. But, what I would like would be to make querying for the history easier and more efficient. In other words,
select * from audit.logged_actions where table_name = 'xxxx' and record_id = 12345;
another edit: I'm using PostgreSQL 9.1
Thanks!
You didn't mention your version of PostgreSQL, which is very important when writing answers to questions like this.
If you're running PostgreSQL 9.0 or newer (or able to upgrade) you can use this approach as documented by Pavel:
http://okbob.blogspot.com/2009/10/dynamic-access-to-record-fields-in.html
In general, what you want is to reference a dynamically named field in a record-typed PL/PgSQL variable like 'NEW' or 'OLD'. This has historically been annoyingly hard, and is still awkward but is at least possible in 9.0.
Your other alternative - which may be simpler - is to write your audit triggers in plperlu, where dynamic field references are trivial.
