I'm trying to cast a varchar into a date with this following code, and the following error is outputting, any idea why?
ALTER TABLE import.employee
ALTER COLUMN birth_date
TYPE date
USING (birth_date::date);
ERROR: date/time field value out of range: "05/29/1960"
HINT: Perhaps you need a different "datestyle" setting.
********** Error **********
ERROR: date/time field value out of range: "05/29/1960"
SQL state: 22008
Hint: Perhaps you need a different "datestyle" setting.
Set the datestyle before:
set datestyle = mdy;
If you need to get the ::date from birth_date, first give the DATE format to your field using the given functions in Data Type Formatting Functions docs.

In Snowflake, I have a column in a created table called "Date1", that has dates formatted as AUTO (ex. 2022-06-17). I am trying to query that column, but need the date formatted as 'MM/DD/YYYY', yet everything I've tried returns an error of some kind.
When I try date(Date1, 'MM/DD/YYYY) the error says that it can't parse 2022-06-17 for MM/DD/YYYY. When I try to_date(Date1 [MM/DD/YYYY]) or try_to_date(Date1 [MM/DD/YYYY]) the error says it doesn't recognize MM.
Any thoughts?
If you're trying to display the date using a specific format, you're converting to a varchar rather than a date:
select to_varchar(current_date, 'MM/DD/YYYY');
If you're trying to compare a column with a date to a formatted string in MM/DD/YYYY format then:
select current_date = try_to_date('08/04/2022', 'MM/DD/YYYY');
You should try to provide correct format to match 2022-06-17 literal:
SELECT TRY_TO_DATE(Date1, 'YYYY-MM-DD')
FROM tab_name;
Your column is already of type DATE. TO_DATE() and TRY_TO_DATE() convert non-date formats (string, integer) to a DATE type. They are not a means to format your DATE for presentation.
Date data type and presentation format are indepent.
You can alter your session to change the default display format of a date, but the underlying representation in the database remains the same.
alter session set DATE_INPUT_FORMAT='MM/DD/YYYY';
alter session set DATE_OUTPUT_FORMAT='MM/DD/YYYY';
select <col_name> from table; -- Now will show as MM/DD/YYYY for date columns
I'm trying to convert a varchar column to date or datetime but I don't understand why it's not possible it should work and I don't see any kind of error.
The column values is 31-07-2017 and the type is Varchar(250). I tried convert and cast and I get the same error:
Conversion failed when converting date and/or time from character string.
Does anyone have any idea on why it's like this?
The conversion error is because your session setting is other than DATEFORMAT dmy or varchar values do not conform to DMY format.
For the latter case, run the query below to identify problem values:
SELECT YourDateColumn AS InvalidDate
FROM dbo.YourTable
WHERE
YourDateColumn IS NOT NULL
AND TRY_CONVERT(date, YourDateColumn, 103) IS NULL;
As #TimBiegeleisen mentioned in a comment, it is best to choose the most appropriate column type (date in this case) for the data to be stored. Not only will this avoid errors like this, it will improve performance and better ensure data integrity.
I found the issue, it's a very very stupid mistake, there was one column with a text format I couldn't see it because I checked with length, but the SQL gives max length so I used group by and manually check dates until I found one column that's not correct in 1 m account records
I need help with the below query. I am getting an error message :
ERROR: Error fetching from cursor. ORACLE error is ORA-01840: input
value not long enough for date format.
What input value is this referring to not being in date format? I can't figure this out. I do see where it refers to AND Removed>= TO_DATE('08162011', 'MMDDYYYY').
Removed
Probably you have a value like TO_DATE('0816', 'MMDDYYYY') for
TR_EFF_DT input, and that does not fit with respect to the date
format, as in the following statement :
with tab(TR_EFF_DT) as
(
select TO_DATE('0816', 'MMDDYYYY') from dual
)
select *
from tab
where TR_EFF_DT>= TO_DATE('08162011', 'MMDDYYYY');
Error:
ORA-01861: literal does not match format string
OR you probably have a mismatch for your DB server's Date Format with your current session's Date Format. In this case you
may issue :
ALTER SESSION SET nls_date_format='MMDDYYYY';
pgAdmin III always gives an error on year
ERROR: function year(date) does not exist
LINE 1: SELECT YEAR(geboortedatum) as date_part
.............................^^^^.........
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
********** Error **********
ERROR: function year(date) does not exist
SQL state: 42883
Hint: No function matches the given name and argument types. You might need to add explicit type casts.
Character: 8
I can get the whole date that I need but I need only the year can someone help me it needs to be the youngest year from the table.
As you mentioned pgAdmin, I assume that you are using Postgres, so you need write code like this (using EXTRACT constructure):
SELECT EXTRACT(YEAR FROM TIMESTAMP '2001-02-16 20:38:40');

I am trying to cast a column as smalldatetime from varchar. There are some rows containing errors, how can I find them?
SELECT
PA.EAR_TAG
,ISNULL(B.DISPOSAL_DATE, H.DISPOSAL_DATE) as HB_Date
,Y.[DATE OF MOVEMENT] as Y_Date
,DATEDIFF(DAY, ISNULL(B.DISPOSAL_DATE, H.DISPOSAL_DATE), cast(Y.[DATE OF MOVEMENT] as smalldatetime))
FROM
DairyTelomere.dbo.PROJECT_ANIMALS AS PA
LEFT JOIN
Langhill.dbo.YOUNG_STOCK_BULL AS B ON Pa.EAR_TAG = B.EAR_TAG
LEFT JOIN
Langhill.dbo.YOUNG_STOCK_HEIFER AS H ON PA.EAR_TAG = H.EAR_TAG
LEFT JOIN
DairyTelomere.dbo.Young_Stock_culls AS Y ON PA.EAR_TAG = Y.Ear_Tag
The error I get is:
Msg 242, Level 16, State 3, Line 1
The conversion of a varchar data type to a smalldatetime data type resulted in an out-of-range value.
I know that if the column was in a date format I could check it by using ISDATE() but unfortunately I can't change the column type (don't have permissions).
Any ideas will be greatly appreciated.
you can use the isdate to get a list of all the ones that are not converting for you. You dont need to change the column type to use this so i am confused by your statement
if the column was in a date format I could check it by using ISDATE() but unfortunately I can't change the column type (don't have permissions)
Will help more if you can clarify but this query should get you a list of rows that have bad date values.
select table.date_as_varchar
from table
where isdate(table.date_as_varchar) = 0
adding to #workabyte answer you can also try using TRY_PARSE, TRY_CAST OR TRY_CONVERT, all of them return NULL if the conversion failed, that way you can know wich rows caused the error.
TRY_PARSE
as the documentation says:
Use TRY_PARSE only for converting from string to date/time and number
types. For general type conversions, continue to use CAST or CONVERT.
Keep in mind that there is a certain performance overhead in parsing
the string value.
Usage example:
SELECT TRY_PARSE(your_date AS DATETIME USING 'es-ES') as date
FROM your_table
es-ES is a culture parameter,different culture paramaters yield different results in your conversions, you can find the full list of parameters in the documentation
TRY_CONVERT
as the documentation says:
TRY_CONVERT takes the value passed to it and tries to convert it to
the specified data_type. If the cast succeeds, TRY_CONVERT returns the
value as the specified data_type; if an error occurs, null is
returned. However if you request a conversion that is explicitly not
permitted, then TRY_CONVERT fails with an error.
Usage example:
SELECT TRY_CONVERT(DATETIME,your_date,103) as date
FROM your_table
The 103 being the style/format of the date you are converting, here you can find a list of the formats avaliable
TRY_CAST
as the documentation says:
TRY_CAST takes the value passed to it and tries to convert it to the
specified data_type. If the cast succeeds, TRY_CAST returns the value
as the specified data_type; if an error occurs, null is returned.
However if you request a conversion that is explicitly not permitted,
then TRY_CAST fails with an error.
Usage example:
SELECT TRY_CAST(your_date AS DATETIME) as date
FROM your_table
