Mapping A String Field To Boolean Output In SELECT Clause

Oct 18, 2006

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!

How Do I Select Data Using A Datetime Field In The Where Clause?

Oct 15, 1998

I would like to do something like this, but it does not work.

Select * from PS_AUDIT_EMPLYMNT
WHERE AUDIT_STAMP LIKE `Oct 15 1998%`

*Note AUDIT_STAMP is a Datetime field

Does anyone have any ideas why this will not work?

Thanks,

SELECT Clause To Determine If A Field Is Japanese

Jun 8, 2007

I am currently trying to find a way in which I can determine if a column in a Select clause is Japanese. The column currently supports English and Japanese Kanjis and other kanas. Is there a way to determine if this column is not English or if it is Japanese without physically looking at it.?

Converting SELECT Output To String

Nov 23, 2005

I'm looking for some good hints and tips for reprogrammin an old VB module I just found.

Basically what it does, is receive an input parameter (an int), does a select [name row] from Names where Name_id = [input parameter] and turns this into a string if multiplenames appear.

E.g. result set: John, Josh, Jock turns it into string "John Josh Jock".

So its piece of cake creating a stored procedure selecting data on the base of an input parameter. Select X from Y where Z = @input... the trick is, I don't know how to do arrays in TSQL as in VB.

In the VB edition I create an array, load the names into it, I do a count on how many row the select returns and then a simple for... next adding the names to the string.

Any good examples on how to do this in a sql-server stored proc?

Thanks,

Trin

P.S. This is what I have pieced together this far:


CREATE PROCEDURE findnames

@number int

AS

DECLARE @instrument varchar(50)
DECLARE @tempinstt varchar(10)

DECLARE medlemcursor CURSOR
FOR
SELECT [MCPS Kode]
FROM DW.dbo.names(NOLOCK)
WHERE number = @number

OPEN medlemcursor

FETCH NEXT FROM medlemcursor INTO @tempinstt
WHILE (@@FETCH_STATUS <> -1)
BEGIN
SET @instrument = @instrument + @tempinstt + '-'
FETCH NEXT FROM medlemcursor INTO @tempinstt
END

CLOSE medlemcursor
DEALLOCATE medlemcursor

SELECT @instrument
GO


Just doesn't seem to work, returns NULL, even though I've checked that the cursor SELECT statement actually returns data,

Multi-Select String Parameter Values Are Converted To N'Value1', N'Value2' In Clause When Report Is Run

Apr 14, 2008



I understand that Multi-Select Parameters are converted behind the scenes to an In Clause when a report is executed. The problem that I have is that my multi-select string parameter is turned into an in claused filled with nvarchar/unicode expressions like:


Where columnName in (N'Value1', N'Value2', N'Value3'...)

This nvarchar / unicode expression takes what is already a fairly slow-performing construct and just drives it into the ground. When I capture my query with Profiler (so I can see the In Clause that is being built), I can run it in Management Studio and see the execution plan. Using N'Values' instead of just 'Value1', 'Value2','Value3' causes the query performance to drop from 40 seconds to two minutes and 40 seconds. It's horrible. How can I make it stop!!!?

Is there any way to force the query-rewriting process in Reporting Services to just use plain-old, varchar text values instead of forcing each value in the list to be converted on the fly to an Nvarchar value like this? The column from which I am pulling values for the parameter and the column that I am filtering are both just plain varchar.

Thanks,

TC

WHERE Clause Boolean - Different Results Depending On Entered Parameter

Jan 13, 2015

This is for Microsoft Server SQL 2012.

I'm trying to create a WHERE clause that will have different results depending on a parameter that is entered. For example, if you put in a number, it will only calculate the rows where the column ID matches that number. However, if you put in 0, which doesn't exist in that column ID, it will instead calculate all the data in the table.

So the below would be a very basic idea of what I'm trying to do, but I'm not sure how to do it with proper syntax.

WHERE IF ID=0, THEN do this
ELSE do this AND ID=#

Mapping Output Parameter To A Variable!

Apr 25, 2007

Hi there,

I am working on SSIS package that gets data from SQL 2005 Database and writes that to a flat file. But I need to write the count of records as part of the header.

Here is what i am trying:

The OLE DB Source is calling a stored procedure and returning two things i.e. a resultset and an output parameter. The data access mode is SQL Command.



Code SnippetEXEC [Get_logins] ?, ?, ? OUTPUT


In the Set Query Parameters dialogbox, all the three patameters are mapped to three different user variables.

What is happening is that the user variable that is mapped to output parameter is never updated. The header property expression is written as follows




Code SnippetRIGHT("0000000000" + (DT_STR, 10, 1252)@LoginCount, 10)



I tried to watch the variable in watch window but to no avail. Any guidance if it is bug or I am missing some thing? Any thoughts, how can I accomplish this? I have also tried adding Row Count Transformation but its variable has the same behaviour. If I set the value of @LoginCount variable to some value, this initially set value is successfully written to the file header.

Thanks

Bit/Boolean Field Problem

Apr 18, 2008

Greetings,

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.

Best Way To Check If A Boolean Field Is Flagged

Oct 15, 2007

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?

Treating A Table Field As A Boolean Value In A Query...help!

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

Gridview - SqlDatasource - How Do You Get All Values For A Like Text Parameter Or A Boolean Field When Filtering?

Is It Possible To Re-reference A Column Alias From A Select Clause In Another Column Of The Same Select Clause?

Jul 20, 2005

Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

OUTPUT Clause

Nov 7, 2007

Hi,

I'm copying records from table A to Table B. On "insert" being successful I want to delete the copied records from table A. I want to use one single transaction. Could I use OUTPUT to delete all records in table A which key matches the ones on "inserted" ?. I believe it could be possible but I have tried several ways without any luck.

INSERT INTO Table A (Field 1, Field 2)
OUTPUT (DELETE Table B WHERE Key = (SELECT Key FROM Inserted))
SELECT (Field1, Field 2) FROM TABLE B

Or something like that,

Thank you

Input String -&> Table -&> Output String?

Jul 13, 2006

I have a nasty situation in SQL Server 7.0. I have a table, in whichone column contains a string-delimited list of IDs pointing to anothertable, called "Ratings" (Ratings is small, containing less than tenvalues, but is subject to change.) For example:[ratingID/descr]1/Bronze2/Silver3/Gold4/PlatinumWhen I record rows in my table, they look something like this:[uniqueid/ratingIDs/etc...]1/2, 4/...2/null/...3/1, 2, 3/...My dilemma is that I can't efficiently read rows in my table, match thestring of ratingIDs with the values in the Ratings table, and returnthat in a reasonable fashion to my jsp. My current stored proceduredoes the following:1) Query my table with the specified criteria, returning ratingIDs as acolumn2) Split the tokens in ratingIDs into a table3) Join this small table with the Ratings table4) Use a CURSOR to iterate through the rows and append it to a string5) Return the string.My query then returns...1/"Silver, Platinum"2/""3/"Bronze, Silver, Gold"And is easy to output.This is super SLOW! Queries on ~100 rows that took <1 sec now take 12secs. Should I:a) Create a junction table to store the IDs initially (I didn't thinkthis would be necessary because the Ratings table has so few values)b) Create a stored procedure that does a "SELECT * FROM Ratings," putthe ratings in a hashtable/map, and match the values up in Java, sinceJava is better for string manipulation?c) Search for alternate SQL syntax, although I don't believe there isanything useful for this problem pre-SQL Server 2005.Thanks!Adam

insert into TestTable -- ID column of testtable is an Identity field

output inserted.id, inserted.col1 into @insertedRecords

SSIS Parameter Mapping With Oracle Data Type Mapping!

Mar 19, 2008

Hi Friends,

I have a small problem in parameter mapping for Execute SQL Task.
I am using a delete statement with 2 conditions.
Followed by another Execute SQL Task which contains commit statement.

delete from tname where c1 = ? and c2 =?

where c1 is number(4) datatype and c2 is of varchar2(20) datatype in oracle.


The connection manager i am using is ORacle OLE DB provider.
I am passing 2 global variables i.e g_v1 of Int32 and g_v2 of String Type.

In the parameter mapping of the Executing SQL task, i am mapping these 2 variables for
c1 and c2 and changed the datatypes inside parameter mapping as Numeric for c1 and Varchar for c2.

I also set the property as ByPassPrepare = True.

When i am executing the package i getting INVALID NUMBER ERROR.
i believe the SSIS is unable to perform the implict datatype converison.

For the next run, i changed the g_v1 varible datatype to Double and also i changed the parameter mapping for c1 as Doble datatype.
This time it is working fine. I can see the Green signal for the 2 SQL Tasks.

But when i connected to Oracle check the count in the table, the data is not getting deleted.

Also,
I set the property RetainSameConnection = TRUE for oracle connection manager.
I am not able to trace this logical error.

The same is working fine in my local machine.
But i am facing the problem when i deployed the same on the client machine.


Is there any problem with parameter mapping?
What should be equialent Datatype for Oracle NUMBER datatype that should be used inside the SSIS package while declaring the global variable and
inside the parameter mapping.

Any thoughts!

SQL Server 2012 :: OUTPUT Clause Returning Wrong Row?

Nov 6, 2014

I'm looking at various methods for deleting duplicate rows. Among the alternatives, one works just fine but gives me results that make me go?.

Consider this script:

declare @t table (a int, b int, c int, d int, e int)
insert into @t (a, b, c, d, e) values
(1, 2, 3, 4, 5),
(3, 4, 2, 3, 4),
(1, 2, 3, 4, 5)

select a,b,c,d,e, rn = row_number() over (
partition by a,b,c,d,e

[Code] ....

The code works -- that is, the duplicate row is deleted. However the output clause returns:

abcdern
123451

So....why? Why does the output clause show that the row with rn=1 was deleted, when the where clause stipulates rn > 1?

Preferrably the query should also be passed as a parameter to the stored procedure...If not,it should be constructed in the SP and a Part of the where clause is dependant on the value of another variable passed to the SP.

How should the query be constructed, executed, and then the Count(*) value returned?
