I'm hoping that what I have paints a clear enough picture of what I am trying to accomplish:
SELECT [Date]
,[ChargeCode]
,[ChargeDescription]
,[HHY_Qty]
,[PatPrice]
, IF ISNUMERIC(HHY_Qty) AND ISNUMERIC(PatPrice)
BEGIN
CAST(HHY_Qty AS INT) * CAST(PatPrice AS INT) AS ExtAmt
END
ELSE
0 AS ExtAmt
END
FROM [dbo].[ChargeDetails]
WHERE PatientNumber = '1271'
HHY_Qty and PatPrice are both VARCHAR types in a MSSQL database. They were created with a BULK INSERT from a very very very dirty CSV from an AS400 export. Here, I am trying to do some multiplication IF the fields are numeric values, otherwise ExtAmt should be 0. Is that possible? If not,, is there a workaround?
Use a CASE statement:
CASE WHEN ISNUMERIC(HHY_Qty) = 1 AND ISNUMERIC(PatPrice) = 1 THEN CAST(HHY_Qty AS INT) * CAST(PatPrice AS INT) ELSE 0 END AS ExtAmt

I have prices coming in my source file like below -
78-22¼,
78-18⅝
I need to calculate these price. For example for first case result should be 78-22.25. I searched a lot but found that SQL supports few of these characters only. Is there anyway to make sure we are able to calculate for whatever value we are getting. Solution in either SQL or PowerShell could work.
You could write a PowerShell function to convert the fractions to decimals:
PS ~> ConvertTo-Decimal '18⅝'
18.625
To do so, we'll need to write a function that:
Uses regex to identify and extract the integer and fraction parts
Uses [char]::GetNumericValue() to get the decimal representation of the fraction
Outputs the sum of the two
function ConvertTo-Decimal {
param(
[Parameter(Mandatory)]
[string]$InputObject
)
if($InputObject -match '^(-?)(\d+)(\p{No})?$'){
$baseValue = +$Matches[2]
if($Matches[3]){
$baseValue += [char]::GetNumericValue($Matches[3])
}
if($Matches[1] -eq '-'){
$baseValue *= -1
}
return $baseValue
}
return 0
}
Hoo this one was fun.
If you want to do it purley in TSQL give this a tug:
DECLARE #table TABLE (Glyph NVARCHAR(2), Dec DECIMAL(8,6))
INSERT INTO #table (Glyph, Dec) VALUES
(N'¼', 1.0/4),(N'½', 1.0/2),(N'¾', 3.0/4),(N'⅐', 1.0/7),
(N'⅑', 1.0/8),(N'⅒',1.0/10),(N'⅓', 1.0/3),(N'⅔', 2.0/3),
(N'⅕', 1.0/5),(N'⅖', 2.0/5),(N'⅗', 3.0/5),(N'⅘', 4.0/5),
(N'⅙', 1.0/6),(N'⅚', 5.0/6),(N'⅛', 1.0/8),(N'⅜', 3.0/8),
(N'⅝', 5.0/8),(N'⅞', 7.0/8),(N'⅟', 1.0/1)
DECLARE #values TABLE (ID INT IDENTITY, value NVARCHAR(20))
INSERT INTO #values (value) VALUES
(N'78-22¼'),(N'78-18⅝'),(N'10+1')
;WITH sort AS (
SELECT v.*, t.*,
CASE WHEN m.value = v.value THEN
CASE WHEN t.Dec IS NOT NULL THEN REPLACE(p.value,t.Glyph,'')+dec
ELSE p.value
END
ELSE
CASE WHEN t.Dec IS NOT NULL THEN REPLACE(m.value,t.Glyph,'')+dec
ELSE m.value
END
END AS v,
CASE WHEN m.value = v.value THEN '+'
ELSE '-' END AS op,
ROW_NUMBER() OVER (PARTITION BY v.value ORDER BY CASE WHEN m.value = v.value THEN CHARINDEX(m.value,v.value) ELSE CHARINDEX(p.value,v.value) END) AS subID
FROM #values v
OUTER APPLY STRING_SPLIT(v.value,'-') m
OUTER APPLY STRING_SPLIT(v.value,'+') p
LEFT OUTER JOIN #table t
ON RIGHT(CASE WHEN m.value = v.value THEN p.value ELSE m.value END,1) = t.Glyph
)
SELECT ID, value, SUM(v * CASE WHEN subId = 1 THEN 1 WHEN op = '+' THEN 1 ELSE -1 END) AS v
FROM sort
GROUP BY ID, value
ID value v

#values replaces your table.
disclaimer: this works, it'll probably perform like hot garbage, but it works :P
In T-SQL you could write a function like this that takes a vulgar fraction and replaces it with its decimal equivalent (this is not completely exhaustive, but handles the most common fractions, and makes a guess about whether you want .666 or .667 or something else for ⅔):
CREATE FUNCTION dbo.FractionToDecimal(#str nvarchar(255))
RETURNS TABLE
AS
RETURN
(
SELECT str = REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(
REPLACE(REPLACE(REPLACE(REPLACE(#str, N'¼','.25'),
N'½','.5'), N'¾','.75'), N'⅓','.333'), N'⅔','.666'),
N'⅛','.125'), N'⅜','.375'), N'⅝','.625'), N'⅞','.875')
);
Sample usage:
DECLARE #x table(str nvarchar(255));
INSERT #x VALUES(N'78-22¼'),(N'78-18⅝');
SELECT [input] = i.str, [output] = o.str
FROM #x AS i
CROSS APPLY dbo.FractionToDecimal(str) AS o;
Output:
input
output
78-22¼
78-22.25
78-18⅝
78-18.625
Working example in this fiddle.
Note there are only so many fraction codes available that you could be pulling in ... so you could add any to the above e.g. from this set but it isn't the case that you would have to handle any possible fraction, only the ones that are represented by these specific symbols. If someone passes in plain text 9/10 or 31/33 that is a completely different problem space than what you have outlined in the question.
I have an issue where I am trying to add a leading 0 to run an output.
SELECT
CASE
WHEN LEN(t.trans_time) = 5
THEN CONCAT(0, [trans_time])
ELSE T.[trans_time]
END AS [TransactionTime]
,RIGHT(CONCAT(0,trans_time),6) AS trans_time
,LEN(T.trans_Time)
,t.trans_time
Why does the case statement not return the leading 0 whereas using:
,RIGHT(CONCAT(0,trans_time),6) AS trans_time
Works no problem.
Case expression return only one type, whereas concat() would return different type & i am assuming trans_time has INT type.
So, you would need to do type conversations :
SELECT (CASE WHEN LEN(t.trans_time) = 5
THEN CONCAT(0, [trans_time])
ELSE CAST(T.[trans_time] AS VARCHAR(255))
END) AS [TransactionTime],
. . .
Another way to do this is to use the format function, wich is available from sql server 2012.
It not only makes the code more readable but will also perform better.
declare #t table (id int)
insert into #t values (90113), (90204), (90207), (90235), (90302), (90318), (90324)
select format(id, '000000') as TransactionTime from #t
this will return
TransactionTime
---------------
090113
090204
090207
090235
090302
090318
090324
IF(
[dbo.tblx.Category] = 'WS' OR [dbo.tblx.Category] = 'SEM',
0,
[dbo.tblx.Tonnes] * [dbo.tblx.Grade] / 1000
)
this returns the entire text and not the "calculation"
can someone help me...what am I doing wrong?
i tried
CASE WHEN dbo.tblx.Category = 'WS' OR dbo.tblx.Category = 'SEM' THEN 0
ELSE dbo.tblx.Tonnes * dbo.tblx.Grade / 1000
END AS Metal
Do perhaps insert something before "CASE WHEN"? it is not running
As I understood, you are trying to create a computed column, using value from other table.
I think in this case you have to use a User Defined function in the formula for computed column. If you give more information I can try to write some code for you.
Instead, if you just want to add a column in a query you can use:
CASE WHEN dbo.tblx.Category = 'WS' OR dbo.tblPTx.Category = 'SEM' THEN 0
ELSE dbo.tblx.Tonnes * dbo.tblx.Grade / 1000 END AS NAME_OF_YOUR_NEW_COLUMN
Update
DECLARE #myvar INT;
SET #myvar = CASE WHEN ([dbo.tblx.Category] = WS OR [dbo.tblPTx.Category] = SEM) THEN 0
ELSE [dbo.tblx.Tonnes] * [dbo.tblx.Grade] / 1000
END
I am trying to come up with a sql statement which converts the odometer if stored in km to miles. If the odometer is stored in miles, it leaves as it is.
After the conversion, it then needs to check for Search paramters i.e Mileage.
The steps I have taken is using the Case Statement.
Here is my snippet of the select statement that I am using currently:
DECLARE
#Mileage NVARCHAR(75) = NULL,
#IsMiles BIT = 1,
#Converted NVARCHAR(75) = NULL
SELECT [Id],Odometer,IsMiles,
CASE IsMiles when 0 THEN OdometerValue * 0.62137
else Odometer end
FROM [dbo].[Vehicle]
where IsMiles = 0
Is there anyway to pass the Result of the case statement to ConvertedOdometer. I want to use that value to evaluate against the search Mileage parameters.
Something like this with this condition:
(ConvertedOdometer >=0 AND ConvertedOdometer <= #Mileage)
I am new to Case statement so have used these guides:
StackOverflow
Sql School
Some Blog
Perhaps something like this ...
DECLARE
#Mileage NVARCHAR(75) = NULL,
#IsMiles BIT = 1,
#Converted NVARCHAR(75) = NULL
select a.* from
(SELECT [Id],Odometer,IsMiles,
CASE when IsMiles=0 THEN OdometerValue * 0.62137 else Odometer end as ConvertedOdometer
FROM [dbo].[Vehicle]
where IsMiles = 0)a
where a.ConvertedOdometer >=0 AND
a.ConvertedOdometer <= #Mileage
I have an MS-SQL table, with a column titled 'ImportCount'.
Data in this column follows the below format:
ImportCount
[Schedules] 1376 schedule items imported from location H:\FOLDERA\AA\XX...
[Schedules] 10201 schedule items imported from location H:\FOLDERZZ\PERS\YY...
[Schedules] 999 schedule items imported from location R:\PERS\FOLDERA\AA\XX...
[Schedules] 21 schedule items imported from location H:\FOLDERA\MM\2014ZZ...
What I would like to do is extract that numerical portion of the data (which varies in length), but am struggling to get the right result. Would appreciate any help on this!
Thanks.
Try
select left(ImportCount, patindex('%[^0-9]%', ImportCount+'.') - 1)
select SUBSTRING(ImportCount,13,patindex('% schedule items%',ImportCount)-13) from table name
Try this..You can declare it as a SQL function also.
DECLARE #intText INT
DECLARE #textAplhaNumeric varchar(100)
set #textAplhaNumeric = '1376 schedule items imported from location'
SET #intText = PATINDEX('%[^0-9]%', #textAplhaNumeric)
BEGIN
WHILE #intText > 0
BEGIN
SET #textAplhaNumeric = STUFF(#textAplhaNumeric, #intText, 1, '' )
SET #intText = PATINDEX('%[^0-9]%', #textAplhaNumeric)
END
END
Select #textAplhaNumeric //output is 1376
It will work in case of NULL or empty values.
Please try:
SELECT LEFT(Val,PATINDEX('%[^0-9]%', Val+'a')-1) from(
SELECT
STUFF(ImportCount, 1, PATINDEX('%[0-9]%', ImportCount)-1, '') Val
FROM YourTable
)x
