How to get the value of radio button which is printed in the rows in the table created by sql in php code

Asked 2019-Apr-14 at 15:22

I am having trouble in getting the value of radio button for each row of the table plus the id of that row fetched by while loop . this is table for getting the attendance of students and save it against their ids . but i am unable to do so as i have pasted the radio button in loop in echo statement.

If i get the value in php code it just take the value of radio button but it does not take the value of that rows id. But I want both of them at a same time

Here is the code for table and radio button

Every row has its own form that can be submitted separately. One possibility is to add a hidden field to each row containing the id of that row. In your PHP script that is called when clicking on the submit button, you can UPDATE or INSERT your entry according to this id.

QUESTION

Delphi FireDAC query execution tracing not working with connection object created by component

Asked 2019-Feb-04 at 20:00

I created a vcl component which uses firedac to access a PostgreSQL database. This works fine, except for query tracing, which I cannot get to work.

In component constructor, I create connection object, set params etc. In the uses clause, I added FireDAC.Phys.PG and FireDAC.Moni.Base, FireDAC.Moni.FlatFile.

Following the embarcadero docs, the TFDMoniFlatFileClientLink is created before the TFDConnection, and tracing is set to true for both the FDTracer and the FDConnection.ConnectionIntf.

...

ANSWER

Answered 2019-Feb-04 at 20:00

I tried to reproduce your problem in a simple FireDAC testbed of mine, by adding a TFDMoniFlatFileClientLink to it and got a similar result, i.e. the trace file contained entries saying that it had been started and stopped, but nothing in between.

Looking at http://docwiki.embarcadero.com/CodeExamples/Tokyo/en/FireDAC.MoniLayerClients_Sample I seemed to be missing a small but vital step, namely to set the MonitorBy parameter of my FDConnection to 'FlatFile', to match the TFDMoniFlatFileClientLink

So, just before opening the connection in my code, I added the first line below

QUESTION

How to call a function with void return using Firedac FDConnection Component in Delphi XE5?

Asked 2018-Jul-15 at 20:46

I recently started using the [ExecSQLScalar]1 and [ExecSQL]2 methods of the FDConnection component in Delphi XE5. It's very handy not to need to build a Dataset object, like FDQuery just for simple queries or executions. However I had a curious problem when executing a function with void return that has internal validations where it can generate exceptions. I'm using a Postgres database.

...

ANSWER

Answered 2018-Jul-15 at 20:46

Using ExecSQLScalar is fine in this case. This is certainly a bug (which was already fixed, at least in Delphi 10.2.3). As you've correctly pointed out, the problem is in releasing a table storage object instance held by the FExecSQLTab field by using FDFree procedure.

I don't have Delphi XE5 source code but maybe you can see something like this inside (comments about what happened are added by me):

QUESTION

How to count bookings made by people who signed up through an affiliate

Asked 2018-Jul-12 at 20:25

I have a hotel booking site. A user has to sign up before they make a booking. They can either sign up through an affiliate, or from the booking site directly. The affiliates place signup url on their websites, when a user clicks on the link they are redirected to the sign up page of my booking site.

affiliates table

Below is my users table, aff_id means person1 and 4 signed up through affiliates with id’s 1 and 3. Null means person 2 and 3 din’t signup through an affiliate, they visited the sign up page directly.

user table

Below is my booking table

Now I want to count all bookings that were made by people who signed up through affiliates

I know I have to use an asql join statement but I have no idea how to do it.

QUESTION

Azure Data Factory copy activity with stored procedure

Asked 2018-Jul-04 at 14:18

Is there a workaround for the fact that you need to name the first parameter of the stored procedure (the one containing the table type) exactly as the property "tableName" in the input dataaset?

Im using Azure Data Factory V1.

Input dataset (On-premise Oracle source)

...

ANSWER

Answered 2018-Jan-04 at 15:05

I cannot test this right now, but as it is said here https://docs.microsoft.com/en-us/azure/data-factory/v1/data-factory-invoke-stored-procedure-from-copy-activity#stored-procedure-definition "The name of the first parameter of stored procedure must match the tableName defined in the dataset JSON".

In the example it declares two parameters in the sp:

@Marketing [dbo].[MarketingType] READONLY
@stringData varchar(256)

At the dataset it doesnt use the schema prefix, it just says: "tableName": "Marketing", without the schema (try this, as you have the schema in your output dataset definition).

Then at the pipeline, it just gives value for stringData. Also this: "SqlWriterTableType": "MarketingType", see that it doesnt have the schema prefix, and your pipeline definition does have it.

So to sum it up: MarketingType is the actual name of the table and is at the SqlWriterTableType property of the copy activity, while Marketing is the name of the parameter in the stored procedure, and the name of the tablename in the output dataset.

Hope this helps!
