In a select statement, I have a expression that calculates something and the result is in decimal with decimal points, How can I truncate the zeros in right side of decimal point?
My query is something like this:
Select (C1 * C2)/100) As A1, (C3 * C2)/50) As A2 from T1
Best wishes

The simple answer is you don't. Databases are for data storage, and computation - display logic is something for the UI.
In terms of a decimal datatype in .NET you can use the overload of the ToString method which takes an output format to limit the number of decimal places... something like:
decimal d = 1.2345000
string s = d.ToString("#.00####");

The method inside a db is the same. You have to convert it to a string or varchar or whatever the native string type is.
Many of them use the exact same # or 0 to show or not show the decimals.
I have seen this in interfaces where they just expose the query engine and the interface application doesn't do any formatting. Clumsy but sometimes your hands are tied.
to_char(fieldname,'##.00####') is an example in the style of Oracle.
I think the same works in other databases, but you'd have to look at your documentation to get the exact syntax.

Hi,
I'm new here to the forum, and only slightly less new to programming. Does anyone have any books on databases that helped them when they started out?
Any help would be greatly appreciated!
Thanks!

Are you looking for books about database admin?
You need to specify which database. Microsoft SQL Server, Oracle, MySQL, Postgres, ...
They all have different underlying methods of storage and controlling data.
Even though they all work with SQL in similar ways.
Or writing SQL queries?
SQL From the Ground up, by Pyefinch was pretty good.
Or writing Procedural SQL?
-Nothing basic about that.
Or programming C# or C++ against a database?
-Not my field, someone else here will have to speak to that.
You might want to be more specific as to what your goal might be.
Is your objective simply to learn more about what is inside a database?
Relational Database Design by Harrington
Database Administration by Mullins
I've also had pretty good luck with integration books like "Oracle and Microsoft SQL server integration" because they tend to expose things I wouldn't otherwise have found out through comparison.
What's your poison?

If you are using Windows Forms, I found 'Data Binding with Windows Forms 2.0' by Brian Noyes, to be useful. It is all about programming in .NET, rather than database theory, but useful for that aspect of the development process. It also covers, briefly, ASP.NET.

Normally I avoid answering this type of question due to the fact that there are so many good books on the subject out there. This one though shines bright...

Just out of curiosity.
If you bump this value up
@strSQL varchar(2000),
to something higher like
@strSQL varchar(3000),
do you get a different error?
edit:
And I don't know if this matters but you've got a disagreement here:
[GLName] Varchar(200),
@f_GLName varchar(50)
[FileNo] Varchar(50),
@f_FileNo varchar(30)
Weird errors creep in on things like this down the road even if the language lets you do it. I saw one TAL issue that took months to figure out because a variable was cutting a value off with a method like this.

Huh ! you question makes no sense (at least to me anyway) try restating your requirement and see if it gets a more positive response.

Hello,
I have table in microsoft access with fields- partNumber, Date, Status.
( the status field always is one of two words - on or off
can I write a iif statement in sql that says IIf ([partNumber = a certain Date]), the status will automatically display off for those records with that part number.
I already have alot of records entered in database.
I have tried and not used to writing IIf statements in sql-
also wonder can you change a field that has data in it with a iif condition statement.
thank you
|

|

As I understand you then you want to display Status to OFF for some records which contain one certain data in field Date ?
