Ok there is something REALLY wrong with this. You are trying to learn SQL using the absolutely WRONG tools. As I said VB6 is dead, you will not get anything but bad memories from old farts who used to use it.
Access is not a suitable learning platform for SQL it has some weird stuff unique to Access. Port your database to SQL Server (there is a clear migration path) and use the proper tools to learn TSQL.
You are doing yourself a disservice continuing to use these tools as you will need to UNLEARN a lot of stuff. Besides there are a huge number of resources to help you with the current tool sets.

 Excellent points.
I learnt SQL using Access and basically I learnt nothing of use.
Then when I picked up SQL Server and did the training courses, the world of SQL open up to me with its resplendent unicorn rainbows and... okay I am exaggerating a bit but I think you make some very good points in your comment.

I know MyCroft! I am busy porting it over to MySQL but , GEEEEZ, alot must be changed in the code!
But yes, I agree vb6 is dead. It's just that I have an old program I still support. So hanging in there on the last threads of vb6!!
Thank you for your input - I really appreciate it.

Have a look at my other comment where I explain what is going on.
I'd also suggest that you get into the habit of formatting your SQL so that is is easier to read.
Here's an example of a possible way of formatting your SQL:
Select
distinct format(SupplierInvoices.Date, 'dd-MMM-yyyy') as tDate,
Sum(SupplierInvoices.QTY) as lTotal
from SupplierInvoices
where PLU = '" & lblPLU.Caption & "'
and Date Between #" & StartTime & "# and #" & EndTime & "#
Group by format(SupplierInvoices.Date, 'dd-MMM-yyyy')
Union
Select
distinct format(Sales.Date, 'dd-MMM-yyyy') as tDate,
Sum(Sales.QTY) as sTotal
from Sales
where PLU = '" & lblPLU.Caption & "'
and Date Between #" & StartTime & "# and #" & EndTime & "#
Group by format(Sales.Date, 'dd-MMM-yyyy')

I really appreciate all the things you said, Guy. Thanks a ton. I will dive into this this weekend and hopefully by Sunday, have a solution to my own question!
Take care & thanks for your valuable input.

In Access I want to group and assign data according to conditions with 2 values 0 and 1 (true or false) and with the condition NGAYGIAO>= #01/01/2019# and NGAYGIAO <=# 31/01/2019# me How to write commands ? The data I put in the excel file consists of two sheets: Original data and Result, where Original data is the original data sheet that is the result of the problem I need, when running the access issue, ask you to help me with the problem. http://www.mediafire.com/file/hkkw519bw2k3o9h/baitap_data2.xls/file

Your problem description is not very clear, so it's hard to guess what you do and what you need...
However, you could rewrite your condition for NGAYGIAO as
NGAYGIAO BETWEEN #01/01/2019# AND #31/01/2019# which looks more readable.

from the original data I created the result, if the contract in the month has LOAIHD = "FBAN" and between (#01/01/2019# and #31/01/2019#) then [BOOL] = 1 else [BOOL = 0, I will describe the condition of [BOOL] in C# code
for (int i = 0; i < [Original data].Count; i++)
{
bool BOOLEAN = 0;
string SOHD = "";
if([NGAYGIAO].[i]>=#1/1/2019# && [NGAYGIAO].[i] <=#1/31/2019#)
{
for (int j = 0; j < [Original data].Count; j++)
{
if([LOAIHD].[j] == "FBAN")
{
BOOLEAN = 1;
SOHD = [Original data].[HD].[j];
}<br />
}
}
if(SOHD == [Original data].[HD].[i] && SOHD != "")
{
[Result].[BOOL].[i] = BOOLEAN;
}
}

Add a derived column to your selection where the definition is as follows:
=IIF(NGAYGIAO BETWEEN #01/01/2019# and #31/01/2019 23:59:59#,true,false)
You can then sort and group by this column

I had SQL Remote Connections working on a clien't server. For some reason I can no longer connect.
I'm getting
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
The network path was not found
I can remote into their server, I just can't connect to the DB either with SSMS or through my app. The ports are open, and SQL is configured for remote access.
I've tried all the usual debugging techniques, like this, but I can't get in.
Anyone have any other ideas?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.

Named Pipes is disabled in SQL Config Mgr.
I followed this to set up Remote Access.
I also opened ports 1433 and 1434 in Windows Firewall.
Again, no joy
If it's not broken, fix it until it is.

But your error message says you're using named pipes.
Have you checked the client protocol configuration, as well as the server config?

Well, I have checked & rechecked all the settings.. Named Pipes s disabled everywhere that I can see.
Still getting this error

Presuming you are NOT using named pipes and in fact the server is remote (different box) then the way to test connectivity is as follows.
1. Log in to the client box
2. Use telnet to access the other box
3. If telnet works then you have connectivity. If not then no connectivity.
To use telnet you must have the 'host' (name or ip) and the 'port'. Telnet doesn't need to do anything other than connect. That is the entire test.
If you do NOT have connectivity then one or more of the following is true
1. host is wrong
2. port is wrong
3. server is not up
4. server is not configured for the port you used (but see 1.)
5. Network is blocking traffic. This can include firewalls.
If you do have connectivity then you have an incorrect assumption. For example your test used the wrong host/port or your application is using the wrong host/port.

If it fact this is true. It worked at the install site and no longer does, then it suggests something changed in the install. For example
1. Configuration changed
2. Someone changed the stack. For example installed or changed a firewall.
Don't forget the always wildly popular - the server just simply is not running.

Hi guys, just wanted to ask if anyone can help me determine whether a table should be:
1. Left in its traditional database form; and if not why? and what should it be normalised to.
2.< The detailed process of implementing the database using SQL, including the normalisation of the table (should that be required), the identification of the attributes, the Entity-Relationship Diagram, and the use of SQL commands in order to create and populate the tables with data
If you're willing to help please reply or message needed urgently. Many thanks

BCNF (also 3.5NF). Steps are described on wikipedia.

Is always required for relational data.

If you don't know them, stay away from the database

In Oracle DB, what are the terms USER and SCHEMA?
From what I've read, schema refers to all the content a database has (tables, sequences, views ...) which belongs to a USER.
But what is a USER? Is it like an "internal database"? I mean, let say that I have 2 programs (Planet Help | City industries) that each need 2 separate databases. So, can I create a USER with the name planetDatabase, and another with the name cityDatabase, which would mean I have 2 "internal databases"? And in each "internal database" I can create specific users that have restricted access to certain functions in their respective "internal database"? Or I am way off what a USER actually is?
