I am trying to execute my query through Java like this:
public ResultSet execSumStatment2() throws SQLException{ String query = "Select SUM(A) as NCCSeptember from NCC where Datum >= '01-09-2013 00:00:00' and Datum <= '30-09-2013 23:59:59'"; return execStatement(query); } Then i call execSumStatement in the class:
sql.execSumStatement2 () ; When I run it I get the following error message:
java.sql.SQLDataException: ORA-01830: date format picture ends before converting entire input string

I already made a search over the internet, and I guess the problem is the datatype of the date in the query, which should be Date, but everything I tried didn't work...
I'm a beginner in programming so it would be great if you could explain it as simple as possible! Thanks in advance!

This error can occur when you try to enter a date value without using the TO_DATE function. In Oracle, the default date format is generally DD-MON-YYYY. If you try to enter a date value that does not comply with this format, you need to use the TO_DATE function.
picture was converted into a valid date, but the remaining data was not required. To solve this error, you need to use nls_date_format as follows. alter session nls_date_format='DD/MM/YYYY HH:MM:SS AM';
The TO_DATE function accepts an argument of a character data type and converts this value to a DATETIME value. The TO_DATE function evaluates a character string according to the date-formatting directive that you specify and returns a DATETIME value.
The “not a valid month” error could be generated when using SQL for table data that includes a column of data type DATE, or TIMESTAMP. The error could also be generated when using SQL functions that accept a date value with a month portion as argument such as the TO_DATE, TO_TIMESTAMP, and TO_TIMESTAMP_TZ functions.
I think you should not rely on the implicit conversion. It is a bad practice.
Instead you should try like this:
datenum >= to_date('11/26/2013','mm/dd/yyyy') or like
datenum >= date '2013-09-01' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
