Hi everyone,
I'm having trouble with this query in SQL (homework!).
I have two tables: customer and staff.
== Customer (the relevant fields) ==
customer_id
first_name
last_name
== Staff ==
staff_id
first_name
last_name
The question is: "select the first and last names of all customers and staff".
Can anybody help on how to do that? I don't know how to "append" the results of the two queries, and googling I can only find about INSERT ... SELECT, which is not what I'm looking for =\
Best regards to all.

Perhaps the keyword "UNION" may help you.

Hi Guys,

From you brief description;
I am assuming that you are using a central database.
I see that you would need to create a
site table (used to store the sites that will use the database)
Checklist Template (list of things to check off)
Checklist Completed table (a join table that links the site with the completed items from the template table)

Thanks Simon
that extra check list are not common to all sites so. how can i relate those points
like which is required which is not for particular Site?
|
|
|
|
|
well in the check list completed table (more than likely not a good name) you could record the todo item and a datetime completed? and the site that it is linked to.

Your description isn't clear enough, so here's a design that could be used for some interpretations of what you wrote.
0) There are several sites.
1) A check list has several check list items.
2) Each site has a check list with a subset of all available check list items.
3) Each check list item may be on several sites' check lists.
This is a classic many-to-many relationship and the typical implementation is to have (at least) three tables:
Site: ID, Name, etc.
Item: ID, Name, etc.
SiteList: SiteID, ItemID (usually no other data here, but maybe in some cases)
Another schema would allow for defining lists and assigning them to sites:
Site: ID, Name, etc.
Item: ID, Name, etc.
List: ID, Name, etc.
ListItem: ListID, ItemID (usually no other data here, but maybe in some cases)
SiteList: SiteID, ListID (usually no other data here, but maybe in some cases)
This second way may be approriate for your needs, you can define a common list and custom lists and assign multiple lists to the sites. Getting a complete list of all items for a site is simple as well.

Please help!
Thank you.

Create a connection to the database (unknown as you did not name it)
Create a query to extract the data from the unknown database
Put the results of the query in your collection (PHP and is nothing to do with the database)
So the only relevant information you have given us is PHP in a DATABASE forum! Find a tutorial about PHP and your unknown database and work through the tutorial. Come back and ask SPECIFIC questions when you have trouble!

Hi, Mycroft Holmes
Thank for reply.
You means the data can not using Query (MySQL) but use PHP.
Okay I move this forum to Web development. But how to move this topic to Web Development?
Thanks

I have a simple SQL table as follows:
CREATE TABLE [dbo].[DaysMonth](
[SNo] [int] NOT NULL,
[Month] [varchar](20) NOT NULL,
[Year] [varchar](4) NOT NULL,
[NoOfDays] [int] NOT NULL,
[Days] [nchar](10) NULL,
[Holiday] [nchar](1) NULL,
[ToDate] [date] NULL,
[Period] [nchar](30) NULL,
Following is the query:
Select SNo, NoOfDays, [Month], [Year], [Days], [Holiday] From DaysMonth Where [Period]='November,2012' order by ToDate
Now, i'm using this query in web application using ASP.Net environment and C# language within a loop. using SQL Server 2008. basic purpose here is to get all days within a period, say January,2012 in a sorted manner.
Out of 100 times running this query, 97-98 times, it's producing correct result, however, 1-2 times, sort is not working, so instead of 1st to 31st, output coming like 10th to 31st then 1st to 10th. Getting puzzled, as it's a huge application running on multi-user environment, getting very difficult to take care of error which is absolutely unpredictable and illogical. Please suggest where is the problem, thanks to all in advance.

Did you try:
Select SNo, NoOfDays, [Month], [Year], [Days], [Holiday] From DaysMonth Where [Period]='November,2012' order by ToDate ASC
Perhaps the direct order of sorting with "ASC" could help.

Can't you let the SQL-Statement do the work of the loop? It would be more effective!

Thanks, I will try but as sort is set by default as ASC in SQL server, I never put asc separately.

From that, I'd say you have different collations (or regional settings on the client). But AFAIK, that would only apply to string-types, like VARCHAR and NTEXT.
Try converting the datetime to a fixed-format string, and sort on that.

Thanks for your reply. In SQL server, regional setting is set as default. Moreover, I need to do sorting based on Date only otherwise, it will defeat my purpose. However, as you are saying, i will try to do so.
|
|
|
|
|
I got a gut-feeling saying it's converting to DATE to a VARCHAR, that's the only way to have 10 precede the number 2.
Contrary to the previous advice, what happens when you cast it to a DOUBLE? Internally, a date is a floating-point number.
|
|
|
|
|
I notice that your table has Month, Year, Days all as character. If the sort uses these columns it might produce your problem.
|
|
|
|
|
Thanks for varchar columns are not included in sorting.
|
|

Always always always store date/time related values as DATE, DATETIME, etc.; never as string.
|
|
|
|
|
His ToDate is stored as a Date type, first thing I looked for!
