Want to Add 2 columns dollar sign - snowflake-cloud-data-platform

I have 2 columns(Col1 and Col2) in tab1 in snowflake mentioned below
Col1 : $10,
Col2 : $25
I want to add the 2 columns
Select sum(Col1+Col2) as Amt from tab1 ;
But i am facing the error :
Numeric value '$25.00' is not recognized
Please advise how i can add these 2 columns in snowflake and get the result.
Thanks in advance

So because you have the dollar sign saved in the columns, they are maybe of datatype varchar2, but especially they are not of datatype number.
You can't make calculations on varchar2 columns if there are non-numeric characters in the data, so you must get rid of the dollar signs and convert the varchar2-data to numbers, for example like this:
Select sum(to_number(replace(Col1,'$','')) + to_number(replace(Col2,'$',''))) as Amt from tab1;
Better way would be to save the dollar amounts (without the dollar sign) in columns that have numeric datatype, but if that can't be changed then you must change the data to be numeric before making any calculations with it.

Filtering SQL rows based on certain alphabets combination

I have a column that store user input text field from a frontend website. User can input any kind of text in it, but they will also put in a specific alphabets combination to represent a job type - for example 'dri'. As an example:
Row 1: P49384; Open vehicle bonnet-BO-dri 22/10
Row 2: P93818; Vehicle exhaust-BO 10/20
Row 3: P1933; battery dri-pu-103/2
Row 4: P3193; screwdriver-pu 423
Row 5: X939; seats bo
Row 6: P9381-vehicle-pu-bo dri
In this case, I will like to filter only rows that contain dri. From the example, you can see the text can be in any order (user behaviour, they will key whatever they like without following any kind of format). But the constant is that for a particular job type, they will put in dri.
I know that I can simply use LIKE in SQL Server to get these rows. Unfortunately, row 4 is included inside when I use this operator. This is because screwdriver contains dri.
Is there any way in SQL Server I can do to strictly only obtain rows that has dri job type, while excluding words like screwdriver?
I tried to use PATINDEX but it failed too - PATINDEX('%[d][r][i]%', column) > 0
Thanks in advance.
Your data is the problem here. Unfortunately even for denormalised data it doesn't appear to have a reliable/defined format, making parsing your data in a language like T-SQL next to impossible. What problems are there? Based on the original sample data, at a glance the following problems exist:
The first data value's delimiter isn't consistent. Rows 1-5 use a semicolon (;), but row 6 uses a hyphen (-)
The last data value's delimiter isn't consistent. Row 1, 2 & 4 use a space ( ), but row 3 uses a hyphen (-).
Internal data doesn't use a consistent delimiter. For example:
Row 1 has a the value Open vehicle bonnet-BO-dri, which appears to be the values Open vehicle bonnet, BO and dri; so the hyphen(-) is the delimiter.
Row 5 has seats bo, which appears to be the values seats and bo, so uses a space ( ) as a delimiter.
The fact that row 6 has vehicle as its own value (vehicle-pu-bo-dri), however, implies that Open vehicle bonnet and Vehicle Exhaust (on rows 1 and 2 respectively) could actually be the values Open, vehicle, & bonnet and Vehicle & Exhaust respectively.
Honestly, the solution is to fix your design. As such, your tables should likely look something like this:
CREATE TABLE dbo.Job (JobID varchar(6) CONSTRAINT PK_JobID PRIMARY KEY NONCLUSTERED, --NONCLUSTERED Because it's not always ascending
YourNumericalLikeValue varchar(5) NULL); --Obviously use a better name
CREATE TABLE dbo.JobTypeCompleted(JobTypeID int IDENTITY (1,1) CONSTRAINT PK_JobTypeID PRIMARY KEY CLUSTERED,
JobID varchar(6) NOT NULL CONSTRAINT FK_JobType_Job FOREIGN KEY REFERENCES dbo.Job (JobID),
JobType varchar(30) NOT NULL); --Must likely this'll actually be a foreign key to an actual job type table
GO
Then, for a couple of your rows, the data would be inserted like so:
INSERT INTO dbo.Job (JobID, YourNumericalLikeValue)
VALUES('P49384','22/10'),
('P9381',NULL);
GO
INSERT INTO dbo.JobTypeCompleted(JobID,JobType)
VALUES('P49384','Open vehicle bonnet'),
('P49384','BO'),
('P49384','dri'),
('P9381','vehicle'),
('P9381','pu'),
('P9381','bo'),
('P9381','dri');
Then you can easily get the jobs you want with a simple query:
SELECT J.JobID,
J.YourNumericalLikeValue
FROM dbo.Job J
WHERE EXISTS (SELECT 1
FROM dbo.JobTypeCompleted JTC
WHERE JTC.JobID = J.JobID
AND JTC.JobType = 'dri');
You can apply like operator in your query as column_name like '%-dri'. It means find out records that end with "-dri"

Multiply Varchar(50) column and int column in SQL Server

select convert(int, Price_Each) * Quantity_Ordered as Total_Sale
from data
I am trying to multiply two columns where data type of Price_Each is varchar(50), and data type of Quantity_Ordered is int.
Even after convert and casting I am having the same error:
Conversion failed when converting the varchar value ' $11.95' to data type int.
My table name is "DATA"
Order ID
Product
Quantity Ordered
Price Each
176558
USB-C Charging Cable
2
$11.95
176559
Bose SoundSport Headphones
1
$99.99
My problem statement is: create new columns named as total sales per person (by multiplying quantity order with the price each)
Could anyone please help me out?
As mentioned in comment by #Jeroen Mostert, you need to convert to money which handles the currency symbol $. The query would be :
select convert(money, Price_Each) * Quantity_Ordered as Total_Sale
from data
And you should actually change your column datatype to money, then you can easily multiply without casting and definitely you will get more benefits while doing any other processing with this column.
alter table [DATA]
alter column Price_Each money

Converting bigint to smallint shows an error

ALTER TABLE employee
ALTER COLUMN emp_phoneNo SMALLINT;
I am trying to alter the data type from BIGINT to SMALLINT and it is showing this error:
Arithmetic overflow error converting expression to data type int.
I am not able to understand what is wrong.
You have existing rows with values in that specific column that are bigger than the new data type allows.
You need to update or delete the rows that are currently "oversized".
(or not perform the column alter at all .. because most likely you don't want to lose the information)
You can find the rows with this query:
SELECT 'CurrentlyOverSized' as MyLabel, * FROM dbo.employee WHERE ABS(emp_phoneNo ) > 32767
Note a phone number like : 5555555555 (which would be numeric for 555-555-5555) would be greater than the 32767 number.
Even 5555555 (for 555-5555 (no area code)) is too big for 32767.
Also
A debatable topic. But number or string for storing phone numbers...check out this link for food for thought:
What datatype should be used for storing phone numbers in SQL Server 2005?
Personally I think numeric is the wrong data type for phone numbers.
Whatever you do, be consistent. If you go with a string (varchar(xyz)) for example..........store them with no extra characters 5555555555, with hyphens 555-555-5555 , with dot 555.555.5555 .. or whatever but do them all the same would be my advice.

How to Split the String and integer in Sql to find the max and put it in SP or functions to call

I have a Retailer code ,It is combination of varchar and Int =>RT003880 like this
I have create a Retailer code as script-wise every day. So i need the last Retailer code i have inserted.
So I have split the Integer and varchar for finding the Max value.
This is the max value by using Query.
select SUBSTRING(Retailer_code,5,9) as RetailerCode
Into #maxfindtable
from dbo.sample
select MAX(RetailerCode) from #maxfindtable
I need to put in in function or Stored Procedure how to do this
Try:
select max(SUBSTRING(RetailerCode,3,len(RetailerCode)-2))
for RT003880 the integer part is starting from position 3,and
len(RetailerCode)-2 isdefine the length of the substring. i.e: all the
character starting from 3rd position
See SUBSTRING for more clearification.
EDIT 2:
try Using Cast
create table #tab (genId varchar(max))
insert into #tab(genId)
values('RT00031'),('RT00013232'),('RT00034'),('RT00084')
select * from #tab
select max(cast(SUBSTRING(genId,3,len(genId)-2) as int)) from #tab
I'd split the RetailerCode into two columns (one CHAR/VARCHAR and one INT/SMALLINT/NUMERIC) to be able to get some performance out of the table. Possibly use a calculated column to concatenate them if requested. I would never query on the calculated column if it was not persisted, however.
Today I have inserted 10000 new records,its choosing wrong max value. Both The codes Written Same Value,Maximum Value is RT0017898,But It shows RT0009999.
After I have Checked a sample data
RetailerId RetailerCode RetailerName
1 RT00031 mBigBazar
2 RT00034 TBazar
3 RT00084 SaravanaStore It shows Correct Value - 00084
When I have insert a new Record it shows wrongly
RetailerId RetailerCode RetailerName
1 RT00031 mBigBazar
2 RT00034 TBazar
3 RT00084 SaravanaStore
4 RT00013232 NewStore
Now it shows 00084 .why it shows wrong?

How to search from varchar column with - on it

I am trying to search from SQL table where my column where to search is varchar type and my keyword for the search should be imported from Excel, like this:
SELECT table.column FROM table WHERE column="for example"42-3
So, the column consists varchar type variables formed with few numbers then "-" and then one number. To Excel I write for example 42-3 and macro should find every row with 42-3 from that table.
I think somehow I should convert it or take it apart when I could only search by numbers but I don't know how to do that when there is - in the variable.
EDIT:
so, in my SQL table I have a first column where are varchar variables 42-1,42-1,42-2,45-1,46-1... second column I have numbers 1,5,11,3,1,6,2... third column I have amounts 300,52 , 200,10 , 712,31 , 0,44... I should make a search with WHERE command for for example WHERE column1=42-1
I can write this "42-1" straight from excel as string format so that is not a problem, only that the character type is in varchar format and consists - so I can not convert it to integer.
Try using '%' operator
Select * from tableName where column1 like value1+'%'
