I need to convert timestamp to int.
Basically I am looking to convert 2022-04-20 00:21:21:123 into 20220420.
I am trying below the below way but not working.
select usernumber, cast(format(created_date,'YYYYMMDD') as int)
from table1;

note that 'Y' and 'D' must be lowercase and your dataype isn't timestamp that's datetime type.
select usernumber, cast(FORMAT(created_date,'yyyyMMdd') as int)
from table1;

Current code I have is as follows:
select date_parse(column_name,'%Y-%m-%d %H:%i:%s')
This is the error I receive:
Error running query: line 1:19: Column "column_name" cannot be
resolved
I know that the format of the date I inserted is correct because I tested it with a value I have in the database and it returned the correct date value. It may be related to several records having no value in the column specified? Not exactly sure how I would account for that
I'm expecting the code to turn the entire column from a string into a date

I have column StartDate and i need to insert this date
INSERT INTO Products(StartDate) VALUES(2001-01-01 00:00:00.000)
There but it doesn't work
The problem is that you need single quotes around your literal datetime value.
If the millseconds are added depends on the datatype of the column.
INSERT INTO Products(StartDate) VALUES('2001-01-01 00:00:00.000')

I am trying to insert records into my table but keep getting an error due to the dash (Invalid column name 'NJB572'), how can I go about this? I have 2 columns in this table, both VARCHAR.
INSERT INTO dbo.Inventory VALUES
(131-NJB572, 'BROOM')
(PTI-I20, '9/16 IRONWORKERS')
(PTI-I16, '13/16" PUNCH');
You can use quotes to wrap the column names.
Try,
INSERT INTO dbo.Inventory VALUES
('131-NJB572', 'BROOM')
,('PTI-I20', '9/16 IRONWORKERS')
,('PTI-I16', '13/16" PUNCH');

Basically I'm selecting all the rows from a table and stripping the time portion of the date using
CAST(CREATE_DATE AS DATE)
but my results give me the rows I need but the column is unnamed.
How do I give the column a name?
Like this:
Cast(create_date as date) as [Column Name Here]
You can omit the [] if you are not using spaces or reserved words in your column name (which is good practice anyway).
