QUESTION
I have read the recommended answers none of which pertain to my subject.
A database about surgeries performed contains lots of tables and these lots of fields: table dat_patient
(patients, abbreviated "p") numbers about 100, and table dat_optherapie
(surgeries, abbreviated "op") about 1,000 fields. Here is a description of the fields I use for my query:
p.ID
is the autoincremental patient index which is correlated to op.patID
in the surgery table.
op.OP1OPVerfahren
contains the surgical procedure each of which can have 29 string values (from "1" to "28" and "99").
op.OP1Datum
contains the date of surgery.
op.revision
shows how many revisions of a given data set there are (important for tracking changes).
I now want to enumerate all different surgical procedures (29) performed in a table. Embedding the SQL query code into my PHP frame works fine:

Of course, the above-mentioned agglomeration of one SUM(...)
after another does not work as this builds up an array of SQL query result sets in rows which do display the associated MIN, MAX and AVG duration for the type (not the sum!) of surgery performed but cannot be displayed without further ado using PHP.
The resulting SQL query code is like this:

The rquery
package has been out for some time now, but the documentation is still very sparse. There isn't even a tag yet in SO, this question will create it.
Maybe there is someone who can help me nevertheless.
I want to connect to a schema in my Postgres-DB via rquery

I have 50 databases with the same design and structure. For benchmarking data analysis and evaluation of the several thousand of variables contained therein I need to build SQL queries. I have a SuperAdmin account who has the permission to view all these databases through an SSH access.
Now, I can write SQL queries combining data from one database after another using UNION ALL like this (simplified):

Answered 2019-Mar-01 at 17:46You don't need an array of the names. Since they are all similar a simple for
loop should work for you. You also need to do the query in the loop and accumulate the results before you return them.

Answered 2017-Jun-15 at 09:45You will need Jquery in order for Bootstrap's javascript related features to function properly. I believe you only need Tether if you are using Bootstrap components like tooltips.
The order in application.js
matters. Jquery, and Tether if you need it, needs to be loaded in before Bootstrap.

Answered 2017-Aug-23 at 21:09axlj's answer covers the specific points in your question. For a slightly different angle, it would be very difficult to create an easier, better-implemented class for use with SQLite than Dapper. As a side benefit, Dapper supports stronger database systems such as SQL Server and PostgreSQL, should you ever choose to move in that direction, though the SQL itself usually needs to be rewritten. You might start with an SQLite/Dapper tutorial.

Answered 2017-Feb-12 at 11:52How to Get All Images From Server Database by using App tethering?
Actually, this is very simple to do, the way I've done it below.
I hope that by comparing your apps with the two below, you'll be able to figure out what you need to do to get yours to work correctly or, if not, it at least might help refine your q to focus on what the exact problem is.
To stop details like not having your data available here, and use of FMX and Live Bindings (and how you might be using them) getting in the way, I based my apps on the BioLife.CDS data you'll find in your Delphi Samples/Data folder. I based the code of the two apps on Malcolm Groves tutorial here
http://www.malcolmgroves.com/blog/?p=1854
and in both apps I have a ClientDataSet, DataSource, DBGrid, DBNavigator and DBImage in each app, connected up exactly as you'd expect in a minimal db-aware-101 application.
The tethering mechanism sends the first app's CDS data to the second app as a stream,
using the TClientDataSet SaveToStream
and LoadFromStream
methods.
The two apps worked first time with zero debugging.
