I have a table with date field in it. User passes month and year. I need to return records where its date has passed year and month.
For example.
Record in table: time:'2016-01-10', time:'2016-01-01', time:'2015-01-01'.
Passed values: year:'2016', month:'01'.
And the return should be first and second records.
How to do it in oracle?
PS. I tried smth like this time>=date'2016-01-01' and time<=date'2016-01-31' but if the last day is not 31, I will get an exception.
Read this date formatting
If I understand you correct you want something like this
To_char(Your_date_col, 'YYYYMM' ) = yearparam ||monthparam

I am trying to parse a string in java that comes like this:
String test="Unknown"
But users data wants this string as date. Can it be a way to parse or avoid this case?
For example that date to be taken like empty, instead of unknown?
Catch the exception when the Date can't be parsed and set the Date to null or some placeholder value that you know to represent an unparseable date.
edit:
As GhostCat points out in the comments, you may want only "Unknown" to be treated this way, and not unparseable dates in general. Error handling can get complicated... at the very least you should be logging when the date can't be parsed. The exact requirements haven't been stated in your question so how you need to handle errors is not known.

Here is the full error line:
java.time.format.DateTimeParseexception: Text '01-Jan-2020' could not be parsed at index 0
Here is the code I am using that throws the error:
val DATETIME_FORMAT = DateTimeFormatter.ofPattern("d-MMM-yyyy").withZone(ZoneId.of("UTC"))
val parsedTime = DATETIME_FORMAT.parse(input)
the input variable is '01-Jan-2020' as seen in the error line.
I have looked at many similar questions to this one but it's not the expected solution. Can anybody enlighten me on how to solve this problem?
You have to set Locale as second parameter ofPattern method, look below (working code in java)
DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy", Locale.ENGLISH).withZone(ZoneId.of("UTC"));
var parsedTime = dateTimeFormatter.parse("01-Jan-2020");

So i need the following values: Values
I want to get them and save them in a variable for example. Do you have any suggestions for me ?
I want to get them to save the last position of an element. :)
if you have access to your element you can use a reference to it with a ViewChild for example https://angular.io/api/core/ViewChild and then you can use
myElementRef.style.transform
This will only give you a string containing the value of the property transform. If you want to access the values you would have to parse the string.

I have mapped a column in Mysql DB to enum in java. Have added a new value in Java for Enum but not in the database yet. And when I run my junit test by creating a mock dataset I get the following exception java.lang.IllegalArgumentException: Unknown ordinal value for enum class PromotionTypeEnum
does your table's row's cell have a legal value for the enum?

My sqlserver table has a column designed as a BIT datatype. It has values 1 and 0s
Then in my Java code, I do
result = new ArrayList
result.add( (Boolean)(rs.getBoolean("columnName")));
Then when I read the value from the list - it shows as Long.
According to everything I find, it says hat a BIT datatype is supposed to map to boolean.
Why does it come as Long?
What can be done to fix this?
You can call getBoolean directly and let it take care of all the casting/coverting:
result.add(rs.getBoolean("columnName"));
