I have a long query that returns a table like:
ID Name bool
1 Joe 0
2 James 0
3 John 1
When the boolean field is equal to 1 for any of the records I would like to return an empty record set. What is the best way to do this?
I know I could use IF EXISTS but my query is so long that I would prefer not to repeat the query multiple times. Is there an alternative?
Hi all,How do you select and check a boolean value within a stored procedure? I don't know if this is correct or not:DECLARE @CheckStatus bitSELECT @CheckStatus = PREF_STATUS FROM tblPrefsWHERE [PREF_ID] = @PREF_IDIF (@CheckStatus IS FALSE) -- DO SOMETHINGIF (@CheckStatus IS TRUE) -- DO SOMETHING But I'm not sure if what I've used (IS FALSE/TRUE) is the correct way? "PREF_STATUS" is a bit column in my table.Thanks.

Being fairly new to SQL Server, I created a new field with the data type 'bit' so I can store the equivalent of a yes/no response (0 or 1).
When I try to enter either a 0 or 1 into the field via MS SQL Server Management Studio Express table view, I get
"String not recognized as valid Boolean"
I'd appreciate if someone would let me know how I 'noobed' this up.
Thanks very much.
I have a boolean field.
I want the users to be able to select
show all marked YES
show all marked NO
show all.
How can this be accomplished?
Thanks
Hello,
Can anyone say me how i can make a Report with Parameter Boolean field,and as Default Value true and False. ( Both ).
With Multivalue and in the Query = Field in (@BoolPara) have i a Error in the Query.
Thanks
When I enter a a true or false value into a boolean field, what is the proper way to enter it? I'm using:
INSERT INTO tblTable (IsSomething)
VALUES (False)
I've heard that a better way is to use 1 and 0, or something.
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

Hello,
I am facing a problem in a SELECT clause which i cannot solve.
In my SQL table ("myTable") i have a few columns ("Column1", "Column2", "TypeColumn"). When I select different columns of the table, instead of getting the value of TypeColumn, i would like to get a boolean indicating whether its value is a certain string or not.
For example, the TypeColumn accepts only a number of selected strings: "AAA", "BBB", "CCC".
when i do a select query on the table, instead of asking for TypeColumn i would like to ask a boolean value of 1 if TypeColumn is "AAA" and 0 if TypeColumn is "BBB" or "CCC". Also, i would like to make this query while I am also fetching the other columns. And i would like to use one query to get all that. I thought something like thsi would work:
SELECT Column1 AS Col1, Column2 AS Col2, IF(TypeColumn = "AAA", 1, 0) AS Col3
FROM myTable
but this doesn't work in SQL 2005!
Is it possible to do something similar in SQL 2005 using one query only? i am trying to avoid multiple queries for this.
thanks a lot for your help!
I have a gridview connected to a sqldatasource, and it works pretty good. It gives me the subsets of the information that I need. But, I really want to let them choose all the companies and/or any status. What's the best way to get all the values in the gridview...besides removing the filters :)
I thought the company would be easy, I'd just set the selected value to blank "", and then it'd get them all....but that's not working. And, for the boolean, I have no idea to get the value without having a separate query.

Morning...
I've attempted several searches to find my answer but they're not quite the answer Im looking for.
We have a large VB6 system that currently sits on an informix database and I've been given the task of shifting it
onto SQL Server (Note: with as little impact to the code as possible - runtime speed will not be an issue at this early stage)
To cut a long story short, I'm hoping to find where relevent columns are shown as being an identity column.
I expected to see it in INFORMATION_SCHEMA.columns but its not in there (at least not that I can see)
Anyone point me in the right direction?
Cheers
Aaron.
I have a new SSIS package that I add a new string variable to with the EvaluateAsExpression property set to True. In the Properties window, I click inside the Expression property, but do not receive the Browse Button (...) to launch the expression builder window.
This appears to be specific to my machine since this same package behaves as expected on other PCs. I have tried to build my expression in a text editor and paste it into the Expression property, but only the first line of the expression is pasted. Am I missing a configuration or install somewhere? Any thoughts on solutions or work arounds will be greatly appreciated.

hi guys, I'm using SQLServer 2005 and I was wondering how I check if some variable is null or not? I tryied to do as the code show but it doesn't work:
declare @number int
set @number = (select number from numbers where number_id = 1)
if (@number = null)
begin
set @number = 12
end

Hey all,
I've been ehre off and on when I've needed help. And I know someone answered my question last time with the exact info I needed. But I seem to have lost the query I saved.
I pretty much need a query that can filter a field I have adn pull up any records that are not in in date format. My current field is text and I'm trying to convert it over to DateTime but am getting stuck. Seems at least one of the records does not have a date format.
Thank you all.

i need to check each column
and if i don't have the value
than add to a new result row
if not show the missing value
if i have in the field A B C than OK (like day1 + day2)
if i don't have the value A B C than than show it like this a|b|c (like day3)
if i don't have the value c than than show it like this -|-|c (like day4)
if i don't have the value a than than show it like this a|-|- (like day5)
if i don't have the value b than than show it like this -|b|- (like day6)

Obviously, I'm a complete n00b at SQL.
I have a table in Access 2003 with about 6,000 records and there are about 20 records that have duplicate data in the first field (CompID).
I'm trying to make the first field my primary key, so I need to fix these duplicate entry.
I could export to Excel and fix the problem that way, but in the interest of learning SQL I want to figure out how to do it properly.
Thanks in advance for what is hopefully a simple answer.
Check the field existence of a database table, if exist get the type, size, decimal ..etc attributes
I need SP
SP
(
@Tablename varchar(30),
@Fieldname varchar(30),
@existance char(1) OUTPUT,
@field_type varchar(30) OUTPUT,
@field_size int OUTPUT,
@field_decimal int OUTPUT
)
as
/* Below check the existance of a @Fieldname in given @Tablename */
/* And set the OUTPUT variables */
Thanks
I'm about ready to pull my hair out. I have a repeater control, and a date field. If the field is a valid date, I'll use it to calculate and display the person's age. Otherwise, I want to display "N/A". My problem is trying to determine if the date field is null or not.I'm using SQL Server 2005 which allows Nulls in the date field, and for many records I don't have a birth date. It makes sense for these records to leave the date Null. This is my code:Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater1.ItemDataBound If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then Dim LabelIcon As Label = CType(e.Item.FindControl("LabelIcon"), Label) Dim LblAge As Label = CType(e.Item.FindControl("LblAge"), Label) Dim inmate As WAP.prisonmembersRow = CType(CType(e.Item.DataItem, System.Data.DataRowView).Row, WAP.prisonmembersRow) If System.IO.File.Exists(Server.MapPath("~/images/picts/" & inmate.FILE2 & ".jpg")) Then LabelIcon.Visible = True End If If inmate.DATE_OF_BIRTH Is DBNull.Value Then If IsDate(inmate.DATE_OF_BIRTH) Then LblAge.Text = "Age: N/A" Else LblAge.Text = "Age: " & GetBirthdate(inmate.DATE_OF_BIRTH) End If End If End IfEnd Sub How can I resolve this?Diane

I have a column say 'ActivationDate' which is a (database timestamp [DT_DBTIMESTAMP]) which I want to replace with an expression in derived columns
The condition is if 'ActivationDate' field is null or '' then 'Null' else 'ActivationDate'
I am struggling to write this condition. Without condition i.e. at present it saves the value in this database '1753-01-01 00:00:00.000'.
In the preview the 'ActivationDate'field does not show any thing so I recon it is either null or ''
Greetings all,
I have a bit of brainteaser that's going to take some serious thought.
I'm importing information from .xls files into a SQL table. The problem is I need to check for dupes and increment certain fields on success of dupe find and then not insert or delete the dupes.
For example, if I have Adam, Turner, 32, 50 already in the table and someone tries to insert Adam, Turner, 32, 50...I need it to increment to read Adam, Turner, 64, 100 and not insert the record. (Notice 2 fields were incremented.)
With that, I have created an INSERT trigger as follows:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER Trigger [dbo].[trgInsertCheck]
ON [dbo].[MyTable]
FOR INSERT
AS
BEGIN
EXEC sp_UpdateDupes
EXEC sp_DeleteDupes
END
The first stored procedure checks for dupes and updates if any dupes are found as follows:
--------------------------------------------------------------------------------------------------------------------------------------
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER Procedure [dbo].[sp_UpdateDupes] AS
DECLARE @FirstName varchar(20), @LastName varchar(20), @Age int, @Widgets int
DECLARE c1 CURSOR FOR
SELECT FirstName, LastName, Age, Widgets
FROM MyTable
GROUP BY FirstName, LastName, Age, Widgets
HAVING COUNT(*) > 1
OPEN c1
FETCH NEXT FROM c1
INTO @FirstName, @LastName, @Age, @Widgets
WHILE @@FETCH_STATUS = 0
BEGIN
UPDATE MyTable set Widgets = Widgets + @Widgets, Age = Age + @Age
WHERE FirstName = @FirstName AND LastName = @LastName
FETCH NEXT FROM c1
INTO @FirstName, @LastName, @Age, @Widgets
END
CLOSE c1
DEALLOCATE c1
Lastly, it finds all dupes, deletes them and inserts one row back in as follows:
--------------------------------------------------------------------------------------------------------------
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER Procedure [dbo].[sp_DeleteDupes] AS
DECLARE @FirstName varchar(20), @LastName varchar(20), @Age int, @Widgets int --declare all fields in table
DECLARE c1 CURSOR FOR
SELECT FirstName, LastName, Age, Widgets
FROM MyTable
GROUP BY FirstName, LastName, Age, Widgets
HAVING COUNT(*) > 1
OPEN c1
FETCH NEXT FROM c1
INTO @FirstName, @LastName, @Age, @Widgets
WHILE @@FETCH_STATUS = 0
BEGIN
--Delete all dupes...the cursor remembers the current record
DELETE FROM MyTable
WHERE FirstName IN (SELECT FirstName FROM MyTable GROUP BY FirstName HAVING COUNT(FirstName) > 1)
AND LastName IN (SELECT LastName FROM MyTable GROUP BY LastName HAVING COUNT(LastName) > 1)
AND Age IN (SELECT Age FROM MyTable GROUP BY Age HAVING COUNT(Age) > 1)
AND Widgets IN (SELECT Widgets FROM MyTable GROUP BY Widgets HAVING COUNT(Widgets) > 1)
--insert the current record back into the table
INSERT INTO MyTable(FirstName, LastName, Age, Widgets) VALUES(@FirstName, @LastName, @Age, @Widgets)
FETCH NEXT FROM c1
INTO @FirstName, @LastName, @Age, @Widgets
END
CLOSE c1
DEALLOCATE c1
Is there an easier way to do this?
(I know Age doesn't make much sense in this example but just replace it with a field would logically be incremented such as wadgets.)

Is there a way to check the data type and the maximum length of a field?

Code:
IF ((SELECT Note FROM XATPoDetail WHERE ReqNbr = (SELECT ReqNbr FROM Inserted)) LIKE(''))
Note is the text field, XATPoDetail is the table where its being inserted into. I had to do the select FROM the table because it wouldn't let me select a text data type from the "Inserted" virtual table
but it tells me me "Error 279: The text, ntext, and image data types are invalid in this subquery or aggregate expression"
thanks

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.

I have a FormView with a couple of TextBoxes, a DropDownList and two CheckBoxes. I have connected a SQLDataSource to the FormView with an InsertCommand to store the values entered into the different conrtrols. My problem is that the boolean values from the two CheckBoxes doesn't get stored in the Database (SQL Server Express). The columns in the DB are of type "bit", should I choose a different type? I don't see any errors just a NULL value in the DB.
I'm probably missing the obvious taken that I'm really fresh to this, so any help would be appreciated...
