Boolean ? In SQL (2005) Table
Dec 3, 2006I was wondering what should be used for a yes/no/ entry identifier . Should it be a simple int , tinyint , or uniqueidentifier?
Thank you

How Would You Set Up Boolean With SQL Server 2005 Express And Vb2005
Dec 19, 2006Im used to using access and now im gonna switch to sql server 2005 express. My program is coded in Visual basic 2005 where all connection is made to the access database by oledb.
Now when im creating the database in management studio express, ive noticed that there is no boolean datatype, but instead there is a bit datatype.
Is this the one to use, and would the bit datatype accept true/false values when sending sql commands? In visual basic2005 i think that it uses 0 for true and -1 for false or something like that, so when switchin database i would have to recode quite a bit.
Or is simpler than this?
Save Boolean Values In A Sql2000 Table
May 21, 2005I try to insert VB.NET boolean true values into a SQL2000 table thru a stored procedure. While varchar fields of the table are correctly filled, I'm surprised to find the bit fields all stay 0 after every single insert. This makes me wonder if VB.NET boolean variables can be passed to sp bit parameters and inserted into a SQL2000 table. Or did I miss something? Please advise. Thanks.

Feb 29, 2008
I wanted to test how SQL server 2005 works with Boolean values.
so I created this table
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[BoolTest](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Operand1] [bit] NULL,
[Operand2] [bit] NULL,
CONSTRAINT [PK_BoolTest] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
I populated it like so
insert dbo.booltest (operand1, operand2) values (1,1)
insert dbo.booltest values (1,0)
insert dbo.booltest values (1,null)
insert dbo.booltest values (0,0)
insert dbo.booltest values (0,null)
Then I tried this
select case when operand1 OR operand2 then 'True' else 'False' End
from dbo.booltest where id=1
thinking that since row 1 has 1 and 1 I'll get 'True' as a string showing in the output window
but instead I got this error
Msg 4145, Level 15, State 1, Line 1
An expression of non-boolean type specified in a context where a condition is expected, near 'OR'.
question:
how do you work with bit value table Fields as booleans in a boolean test
many thanks in advance for your time/help

Optimising A Table With Lots Of Boolean Fields
Jul 17, 2006I have an application that reads a monitoring devices that produces 200 digital outputs every second and I would like to store them in a table. This table would get quite big fairly quickly as ultimately I would like to monitor over a hundred of these devices.
I would like to construct queries against each of the individual digital channels or combinations of them.
M first thought is to set up a table with 200 separate columns (plus others for date stamp, device ID etc) however, I am concerned that a table with 200 boolean (1-bit) fields would be an enormous waste of space if each field takes maybe one to four bytes on the hard disk to store a single bit. However, this would have the advantage of make the SQL queries more natural.
The other alternative is to create a single 200 bit field and use lots of ANDing and ORing to isolate bits to do my queries. This would make my SQL code less readable and may also cause nore hassle in the future if the inputs changed, but it would make the file size smaller.
In essence I am asking (hoping) the following : If I create a table with 200 boolean fields, does SQL server express automatically optimise the storage to make it more compact? This means that the server can mess around at the bit level and leave my higher level SQL code looking cleaner and more logical.

View 5 Replies View RelatedConverting Boolean To Bit
Mar 2, 2005I have a control with checkboxes. The checkbox.checked property returns a boolean value. If I want to insert a record into a table that has a corresponding column of type bit, how do I do it?
I triedCType(myChkBox.checked,String), which returns the strings "True" or "False". But, I get the errorThe name 'True' is not permitted in this context. Only constants, expressions, or variables allowed here. Column names are not permitted.I then tried "CAST(" & CType(myChkBox.checked,String) & ",bit)", but got the same error.
I can write a function that will return a 1 or a 0 but that seems ludicrous. Surely there must be a more elegant way to use the result of a checkbox in an SQL statement.
Thanks

Hi,
I have a Summary report and a Detail (drillthrough) report.
the summary report displays.
Summary report
Code Snippet
Adult | Male | Count
-----------------------------
Yes | Yes | 50
Yes | No | 9
No | Yes | 20
No | No | 50
------------------------------

When the user clicks on the hightlighted count it links to the Details report displaying each of the records referenced.
The detail report uses 2 boolean parameters Adult & Male, this works perfectly for the first 4 lines displayed, however if the user clicks on the total value to display all the records, i'm unable to provide the NULL value.

Boolean Expressions
Nov 12, 2007I have a unusual problem, well it is unusual becaue i cannot understand it.
I am retrieving the following data, Revenue, Sales, Commission, and calculating Commission Rate in the report itself.
I got warnings that a textbox that was attempting to calculate the Commission Rate was trying to divide by zero.
When I analysed the data, I realised that indeed there were instances when Revenue was 0.00 and therefore when calculating the commission rate, commission/revenue it returned an error.
I then thought I'd do the following in the expression field
=iif((Fields!RevenueGbp.Value = 0.00), "Zero", (Fields!Commission.ValueGbp/Fields!RevenueGbp.Value))
However this does not work. However if i tried the following Boolean query
=iif((Fields!RevenueGbp.Value = 0.00), "Zero", Fields!CommissionGbp.Value)
it does work. In fact if I use any other identifier or use two field thats add, subtract or multiplied with each other it will work. The problem only arises is when I decide to divide two fields together.
Strangely if the condition is satisfied - [Fields!RevenueGbp.Value = 0.00] - it will still try to work out the division even though it should just return Zero!
Anyone help?

Where's The Boolean Data Type?
Jun 19, 2005Obviously, I'm new to SQL Server, because I'm still scratching my head wondering where in the world the boolean data type is. Can anyone please explain to me how boolean data types REALLY work in SQL Server? I've created a few Bit type fields, but when using a datagrid, they sometimes show up as 0 and 1 and sometimes as True/False, and I can't see a difference in how the grids (or fields(!)) are set up that would explain this. Any insight would be greatly appreciated!

Dynamic Boolean Searches AND, OR,
Jul 5, 2002Hi, I am looking for an easy and efficiant way to add a boolean search function to an already existing search i have using ASP pages and MSSQL 2000 SPROCS.
Currently I have some code such as:
CREATE PROCEDURE sp_name
@var1 int = NULL,
@var2 varchar(50) = NULL
AS
SELECT blah, blah, blah
FROM sometable INNER JOIN anothertable ON anID = anID
WHERE (table1.column2 = COALESCE(@var1,table1.column2) AND table2.column4 = COALESCE(@var2,table2.column4))
and this works like a charm, if i pass a value into @var1 or @var 2 it gives back results where those crietera match, or if I pass no values in it returns all records.... anyways, you get the idea...
Now I would like to add the ability to introduce a 3rd variable, and have it run a boolean search on a varchar(2500) column. This column is a description field for an image so I would like to be able to search the descriptions by passing in something like 'car OR bike AND travel' and return all the records that have the words 'car' or 'bike' and 'travel' somewhere in the description field.
How can i do this? I am using SQL Server Standard Edition so I don't believe I have full text search functions available, (not sure if that would even help).
Thanks all for your support and guidance!
P.S. i would also like to maintain the functinality so that if all the @var# are blank it still returns all records.

Boolean - Expanded/Collapsed
Jul 12, 2007I have created a matrix where I have booleans on the rows and columns. They are initially in the collapsed state. For reporting purposes, I would like the initial state to to be expanded or at list a quick fix to quickly convert the collapsed booleans to expanded booleans.
I have navigated to the Layout tab and right-clicked the fields that are tied to the boolean and then clicked on the properties. This bring sup the Textbox Properties. From here, I click on the Visibility tab. At the bottom of the textbox is a section "Initial appearance of the toggle image for this report item:". The default choice is marked as collapsed (+). One would logically think that you you would have to do then is select the expanded (-). choice. Well, when I do this, all it simply does is chance the icon from a '+' to a '-' and the fields are still shown as collapsed.
Any ideas on what I need to do?

SSIS Boolean Questions
Oct 24, 2006Please write YES/NO against point number in your answer i.e. for example:
1) YES, 2) YES, 3) NO, 4) YES etc.
We have source SQL Server 200 databases in one instance and target SQL Server 2005 in another instance both being on different windows 2000 server systems.
Target OLAP DB design is derived from source OLTP.
Most master & transaction tables are as is but some target tables are a result of merging source tables.
We need to do SSIS packages based migration using data flow task based on column mapping & queries using Business Intelligence Development Studio (BIDS). There are no transformations required.
1) Can I group packages under project into sub-groups i.e. super packages?
2) Can I execute a set of packages together which are logically/physically grouped?
3) Can we execute set of ordered packages/individual packages from command line and even
stored procedure?
4) Can we maintain transaction integrity across the entire set of ordered packages we execute?
5) Can we send a mail to mail id(s) in case of events like OnError etc.
6) Can we schedule the packages?
7) Does SSIS provide via BIDS a way to compare data in source with target to decide what got
inserted/deleted/updated and based on that do the necessary?
8) Can SSIS packages be developed including code for data encryption?
9) Can we pass parameters to packages that get called from stored procedure?
10) Can we call stored procedure/function in SSIS package?
