Isnumeric Function
Mar 4, 2002The isnumeric function returns 1 in examples where it should not:
select isnumeric('1D9') returns 1.
Can anyone explain this?

How To Handle ISNUMERIC() Function ?
Aug 31, 2006I have a task (Derived Column Task) and I want to write something like this :
IsNumeric(aColumnOfString) == true ? "All numbers" : "there are some characters"
Here aColumnOfString can be something like "123a5" or 12345". I do not want to simply check if the left-most character is a number or not. I want to check the entire expression and return me a TRUE or false.
A TRUE is returned if the entire expression contains ONLY numbers, and FALSE otherwise.
I read some posting using regular expression. But that is not a solution for this situation.
Anyone knows how to accomplish this, please help!
Bug In ISNUMERIC ?
Apr 13, 2004strange thing I just ran into, not sure if this is a bug or what ... but pretty annoying.
In MS SQLServer 2000 :
SELECT (ISNUMERIC('0E010101'))
returns "1"
but
SELECT CAST ('0E010101' AS numeric)
returns "Error converting data type varchar to numeric"
any idea?
IsNumeric() - It Can Not Be Right?
Mar 27, 2006hi,
i am migrating data from a legacy system with a not nice front-end.
as a result, i have all sorts of garbage stored on the tables.
i
am trying to convert values from varchar(12) to float, but i have an
error during selecting data that says that data can not be converted
eventhough i am using the ISNUMERIC() function to check.
case when
isNumeric( myCol01 ) = 0 then null
else
convert( float , myCol01 )
end
but my error occours when ISNUMERIC() encounters the value '. ' ; that is a dot with spaces after it.
try the expression below;
SELECT
myValue = '. '
, is_numeric = ISNUMERIC('. ')
, converted = CONVERT( FLOAT , '. ')
has anyone got any idea how to work around this?

Sum And IsNumeric
Feb 27, 2008Hi,
I have a table described as follows:
TableA
GrpDate DateTime;
grpMiscError varchar(1);
Ex Data:
2/1/2008 1
2/1/2008 1
2/1/2008 0
2/1/2008 x
2/1/2008 0
The grpMiscError can contain 0, 1 or x only. I need to sum up this column for all the zeros by a particular date.
I have the following but doesn't work:
SELECT
SUM(CASE ISNUMERIC(grpMiscError) WHEN 0 THEN 1 ELSE 0 END)AS MiscError
FROM TableA
WHERE GrpDate = '2/1/2008'
I get back an answer of 1 MiscError instead of 2
What am I doing wrong here?
Thanks,

IsNumeric Does Not Appear To Work
Feb 5, 2001Hi all,
I have never seen this problem in SQL Server 7. The isnumeric() returns true for non-numeric data, as show in the following example:
declare @x as varchar(5)
select @x = '00d01'
select isnumeric(@x)
I would expect the isnumeric() function to return false. Can anyone give a reason why this should occur.
Does SQL Server think that this is a hex value and is performing an implicit conversion? If so how horrible...

Isnumeric In SQL SERVER 7
Feb 23, 2005Hello,
I would like to perform a delete statement on one of my tables.
I have a code column that has data in the form 011-234-12
and at some point in this column the data is like R0 or D1
I want to delete the rows where the code data is R0 or D1, E3, etc...
I would like to know how to create an SQL Command for Sql Server 7 that would delete from Soumission_detail where:
first left char is not Numeric in the code column.
Thanks.
ISNUMERIC() In LIKE Statement
Jan 10, 2007HiHere's the problem:I need to search a postcode database by the first one or two letters.Problems occur for example when i want to search north London postcodes (N) when using:postcode LIKE @postcode + '%' As this picks up everything beginning with N, eg, NG for Nottingham, or NE for Newcastle. So i need a like statement which searches for the first one or two digits followed by a number!I've found the ISNUMERIC() function but not sure what the best way to use it with the like statement - or even if there is a better way altogether - can you use regular expressions in MSSQL?thanks

ISNUMERIC returns 1 when the input expression evaluates to a valid integer, floating point number, money or decimal type; otherwise it returns 0. A return value of 1 guarantees that expression can be converted to one of these numeric types.
thanks, but which one??
numeric as far as float is concerned, is not the same thing as numeric as far as money is concerned

Isnumeric Issue
Aug 28, 2007Hi,
I'm casting a varchar field to a decimal field using the format
CASE ISNUMERIC(GrossMktCapGbp)
WHEN 1 THEN CONVERT(DECIMAL(18,6),GrossMktCapGbp)
ELSE NULL
end
Thinking this would ensure that any spurious rows got set to null.
However I had a problem with some values that were set to '.', it seems that isnumeric thinks these are numbers but casting them to decimal produces an error.
SELECT ISNUMERIC('.')
SELECT CAST('.' AS DECIMAL(18,6))
Should I have been doing something different in my check possibly.

IsInteger - Replacement For IsNumeric

View 4 Replies View RelatedTesting For IsNumeric In SSIS
Dec 18, 2007Hello,
I have searched the forum, and have discovered that the DTS method using IsNumeric to check for numierc values (ActiveX) is not valid in SSIS. Most of what I have seen prescribes using the script component to handle this.
So formerly, I checked to see if a column was numeric. If it was, then I needed to use the numeric value as is, or in some cases, I needed to perform a calculation on the value and use the result. If the value was not numeric, then whatever the value was needed to be changed to zero.
Here is an example of how I would use the current value, or set the value to zero:
If IsNumeric(DTSSource("Col003")) Then DTSDestination("ADepTrnx") = CLng(DTSSource("Col003")) Else DTSDestination("ADepTrnx") = 0 End If
This is an example of how I would use the current value in a calculation, or set the value to zero:
If IsNumeric(DTSSource("Col012")) Then DTSDestination("AlliStdFee") = CLng(DTSSource("Col012"))/100 Else DTSDestination("AlliStdFee") = 0 End If
Does anyone have an example of how I would handle both situations in a script component?
Thank you for your help!

SQL 2005: ISNUMERIC() And Views
Sep 10, 2007Hello all!
I've wrote a small query for SQL 2005 and it's doesn't seem to work.
I have a table that contains two columns (X and Y), X is an int and Y is an nvarchar(50). I've populated this table with some data where Y contains numbers and some strings (e.g. "1", "2", "foo", etc). I've then got a view which only returns the rows where Y is numeric - now, I then query this table stating I only want numbers greater than 0 (i've casted the column) but this throws an error stating "foo" can't be casted. This is strange because the view doesn't return that.
What's going on? All of this works fine in SQL 2000 but not in SQL 2005 - looks like it's looking at the underlying table rather than the view. Sample code below to help you all out: -
Create Table
============
CREATE TABLE [dbo].[tblTest](
[X] [int] NOT NULL,
[nvarchar](50) NOT NULL
) ON [PRIMARY]
Insert Data
===========
INSERT INTO tblTest(X, Y) VALUES(1, '1')
INSERT INTO tblTest(X, Y) VALUES(1, '2')
INSERT INTO tblTest(X, Y) VALUES(2, 'foo')
INSERT INTO tblTest(X, Y) VALUES(2, 'bar')
Create View
===========
CREATE VIEW [dbo].[vwTest]
AS
SELECT X, Y
FROM dbo.tblTest
WHERE (ISNUMERIC(Y) = 1)
Finally
=======
SELECT X, Y
FROM dbo.vwTest
WHERE (CONVERT(int, Y) >= 0)
Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the nvarchar value 'foo' to data type int.
Thanks in advance!

Using IsNumeric Within A Case Statement (within An Insert)
Mar 25, 2003Hi - Please excuse me if this is really simple, but I'm fairly new to this lark.
My (made up) code is below... I'd be grateful for any pointers.
insert into [tblInvoices]
(full_period,
supplier_no,
account_code,
tran_amount,
function)
select
full_period,
supplier_no,
account_code,
tran_amount
case
when substring(account_code,1,2) = 'FY' then '-'
when isNumeric(account_code) then left(account_code, 2)
when not isNumeric(substring(account_code,1,2)) then left(account_code, 1)
else 'oops'
end as function,
from
tblLoadMSV900_i
end
Is this even close?
I'm using a stored proc to insert the data from tblLoadMSV900_i into tblInvoices and at the same time insert some data into the function field.
In plain english I want make sure that:
If the first 2 chars of account_code are 'FY' then function='-',
If the first char of account_code is numeric then function=left(account_code, 2),
If the the first char is not numeric (and if first two chars are not 'FY' i.e. first char could be 'F') then function=left(account_code, 1)
And there's plenty more where this came from! But if I can crack this with your help then I should have a better idea about the rest of the proc.
Thanks

T-SQL - Check For Decimal?? Like ISNULL, ISDATE, ISNUMERIC, Etc.

Transact SQL :: Using CAST (column AS BIGINT) And ISNUMERIC

FROM TSEXFIELDV
[Code] ....
And it returns this error:

So, I tried again, and this worked…
SELECT uri, evFieldUri, evFieldVal,CAST(evFieldVal
AS BIGINT),
ISNUMERIC(evFieldVal)
FROM TSEXFIELDV WHERE URI
> 0 AND evFieldUri
IN ( SELECT URI
FROM TSEXFIELD WHERE exFieldFormat

I logged out and came back and tried again, and it still worked. So then I tried…
SELECT uri, evFieldUri, evFieldVal,CAST(evFieldVal
AS BIGINT)
FROM TSEXFIELDV
WHERE URI
> 0
[Code] ...
And it fails.
IsNumeric Does Not Work On Data From Data Conversion Task
Jan 3, 2008Hi,
I have another issue. I have an excel file that I pipe through a "data conversion" task. I have set all the column data types to strings, because there's no way to know beforehand if a particular column will be number or text because the file is very non-standard (it looks more like a formatted report).
After the data conversion, I send all the rows to a script task. In the script task, I do a check on the numeric fields.
for example:
If Not IsNumeric(Row.Price) Then
Row.Price_IsNull = True
End If
However, this check fails each and every time, even if the field contains a number! I don't have this problem when using flat file sources.
So, none of my numeric fields are getting loaded to my ole db destination.
Help, is there a way around this? Or am I forced to just skip this number check altogether? I'd prefer not to.
Thanks

Using A Scalar Valued Function As A Parameter Of A Table Valued Function?
Feb 1, 2006Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't...
I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it.
So the first thing I do, is I need to grab the primary key fields of the table. I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table. Great. I pass in the table name, and sure enough, it comes back with a record set, 1 row per column. That's exactly what I need.
Umm... This is the part where I'm at a loss. The stored procedure outputs the resultset as a resultset (Not as an output param). Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work. But... How do I use the resultset from the stored procedure? You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the syntax like:
DECLARE @table table@table=EXEC sp_pkeys MyTable
That of course just returns you the RETURN_VALUE instead of the resultset it output. Ugh. Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys. Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key. Ok, I test it and it works great.
Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out...
SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT)
Syntax Error. Ugh. Eventually, I even try:
SELECT *FROM Split(substring('abc,def',2,6),DEFAULT)
Syntax Error.
Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function?
SELECT *FROM Split('bc,def',DEFAULT) works just fine.
So my questions are:
Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it?
Is there any way to pass a scalar-valued function as a parameter into a table-valued function?
Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround:
DECLARE @tmp varchar(8000)
SET @tmp=(SELECT dbo.fn_pkeys('MyTable'))
SELECT *
FROM Split(@tmp,DEFAULT)
Calling A Function From A Function?
Apr 11, 2008Hi All
Yesterday Peso was gracious enough to help me with creating function/views/sp's
I took those examples and extended what had from excel into function in SQL

AND hu.Session_Time < 21600000
GROUP BY ut.LastName, ut.FirstName
)
As you can see the first part of the both query are simlar. In particular the:
SELECTut.LastName, ut.FirstName,
CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]
and also the variables @StartDate and @EndDate.
In C# it would create a method and just call that method as well as the variables. However i'm not sure how to do that with sql functions. Could someone shed some light please?
Thank you!

View 5 Replies View RelatedSQL AVG Function
Apr 30, 2007I have a table:tblRateUserUserIDJudge intUserIDJudged intscore int
this table contains the userid of the person giving a score (judge) and the person receiving the score (judged) and the score itself.
Each user can only score another user once.
tblRateUser content:judged judge score6 5 87 5 107 6 515 7 415 5 9
When a new score is inserted I want to get the average score for the rated user by counting all scores for that user and divide by the number of records.
declare @avgscore decimal(4,1) set @avgscore=(select avg(score) from tblRateUser WHERE UserCodeJudged=@ID) print 'avg score: '+ cast(@avgscore as nvarchar(15)) in the above example this results for usercode judged 7 in an average score of 7.0 whereas I would expect 7.5 (10+5)/2
what am I doing wrong?
