My table has two DATE format attributes, however, when i try to insert value it throws an error: date format picture ends before converting entire input string.
Here is my attempted code:
insert into visit
values(123456, '19-JUN-13', '13-AUG-13 12:56 A.M.');
I think the problem is with 12:56 but Oracle documentation says date implies both date and time.

Perhaps you should check NLS_DATE_FORMAT and use the date string conforming the format.
Or you can use to_date function within the INSERT statement, like the following:
insert into visit
values(123456,
to_date('19-JUN-13', 'dd-mon-yy'),
to_date('13-AUG-13 12:56 A.M.', 'dd-mon-yyyy hh:mi A.M.'));
Additionally, Oracle DATE stores date and time information together.

you need to alter session
you can try before insert
sql : alter session set nls_date_format = 'YYYY-MM-DD HH24:MI:SS'

What you’re trying to insert is not a date, I think, but a string. You need to use to_date() function, like this:
insert into table t1 (id, date_field) values (1, to_date('20.06.2013', 'dd.mm.yyyy'));

I had this error today and discovered it was an incorrectly-formatted year…
select * from es_timeexpense where parsedate > to_date('12/3/2018', 'MM/dd/yyy')
Notice the year has only three ‘y’s. It should have 4.
Double-check your format.

The date format picture ends before converting entire input string error happens when the Oracle database has a string that does not match the driver’s expectations. As a result, developers and programmers usually refer to it as ORA-01830 to_char Oracle error because it messes up the valid date format.
Therefore, we wrote this detailed debugging guide that teaches you how to convert string to date in Oracle without causing code exceptions and ruining your code. In addition, we introduced several chapters that remake the date format in plSQL bug, which is critical when troubleshooting your document or script.
Contents
- Why the Date Format Picture Ends Before Converting Input String?
- – Entering an Invalid Date Format
- Fix the Date Format Picture Ends Before Converting the Entire Input String
- – Fixing Another Invalid Instance
- Conclusion
The date format picture ends before converting the entire input string because programmers create an Oracle database with a series that does not match the driver’s expectations. Henceforth, they cannot Oracle convert datetime to date, although it is an operation that only contains a few commands and functions.
However, this is one of the few possible culprits that prevent you to convert timestamp to date in Oracle. Namely, you can sometimes encounter this obstacle when the alter session command exists before the insert, a typical mistake that needs to be clarified for your system.
As a result, your project launches several errors that halt code operations and prevent you from compiling the date format, which is vital for an advanced application. Although pinpointing the exact failed command or property is only sometimes straightforward, we are here to help you debug the syntax.
However, before listing and explaining the sophisticated debugging principles, we will discuss another possible culprit. For instance, this bug usually affects scripts and syntaxes that misinterpret the format picture, or the user provides an invalid input of a specific structure.
As a result, the program cannot render or recognize the values, although they might be standard numbers or letters, which is sometimes frustrating. Therefore, we will start our debugging journey by recreating and troubleshooting the format picture error.
– Entering an Invalid Date Format
Writing the invalid values and properties that confuse your system and launch the error is the best way to comprehend the cause. As a result, we will show you a short script consisting of three parts that attempt to create a date-format picture for an application that requires this input.
Unfortunately, the process ends before converting the entire input string, confusing your system because it has no values to render. In addition, this example confirms your code can have simple elements and provoke a mistake, which is typical for beginners.
The following script provides the main commands and creates a table:
dat date,
xyz varchar2 (11)
);
insert into tq44_tab
select
date ‘2022-01-01’ + level,
to_char (level, ‘fmxxxxxx’)
from
dual connect by level <= 10000;
This introductory syntax establishes the purpose and creates the application. First, however, the example is complete with sessions and inputs, which will help you locate the incorrect property.
You can learn more about the input in the following example:
select xyz from tq44_tab where dat = ‘10.10.2022’;
—
— XYZ
— ———-
— 242
So, after writing the inputs and confirming the changes, the system launches the mistake and its entire exception. The following example provides the incorrect instance:
select xyz from tq44_tab where dat = ‘10.10.2022’;
—
— ORA-01831: date format picture finishes before converting entire input string
—
Although the values appear functional, they are incorrect, and the user interface does not work correctly.
Recreating this mistake is easy when entering an invalid date format that obliterates the complete project or application. As a result, the process finishes before the system converts the whole input string, affecting other child and parent elements, especially those that introduce the date format.
We will show you an example of two parts, where the first one is functional, but the second fails. For instance, the first part converts the input into a valid date, but the second syntax does not match the remaining data.
The following example provides the central values:
Name Null? Type
—————————————– ——– —————————-
EMPNO NUMBER (5)
ENAME VARCHAR2 (11)
HIREDATE DATE
SQL> insert into emp values (101,’Arish’,’16-May-2022 10:54′);
insert into emp values (101,’Arish’,’16-May-2022 10:54′)
*
ERROR at line 1:
ORA-01830: date format picture finishes before converting entire input string
The invalid message indicates where the code fails and whether developers must take any actions. However, you can recreate an exact situation using the to_date command.
The to_date property bugs your syntax in the next example:
select to_date (’16-May-2022 10:54′) from dual
*
ERROR at line 1:
ORA-01830: date format picture finishes before converting the entire input string
SQL> select to_date (’16-May-2022 10:54′,’dd-mon-yyyy’) from dual;
select to_date (’16-May-2022 10:54′,’dd-mon-yyyy’) from dual
*
ERROR at line 1:
ORA-01830: date format picture finishes before converting the entire input string
Unfortunately, this example has no correct values, although they appear full-proof. As a result, you must apply the debugging principles that fix the program and allow further operations.
Fix the Date Format Picture Ends Before Converting the Entire Input String
To fix the date format picture error you must use the to_date command with the correct format when converting the string, and the structure must match the data. Consequently, the system will render the properties and values and provide the correct user output because the input is valid and functional.
However, this is easier said than done because you must make several changes to the code, especially the values that launch the mistake. As a result, we will show you a correct example with replaced elements and values that debugs the syntax from the former chapter.
In addition, programmers must modify the queries, allowing the application to read the required date formats and input strings. So, the initial step requires you to change the to_date function to match the necessary configuration.
You can discover a fully-functional code in the following example:
1 row created.
SQL > select to_date (’16-May-2022 10:54′, ‘dd-Mon-yyyy hh24:mi’) from dual;
TO_DATE (‘
———
16-MAY-22
SQL > select to_date (’16-May-2022 10:54′, ‘dd-Mon-yyyy hh24:mi:ss’) from dual;
TO_DATE (‘
———
16-MAY-22
This syntax confirms several changes to the date format are vital when applying the debugging solution. So, this format matches the string data and allows your system to proceed with all operations. As a result, users can input any data and submit it to the server.
– Fixing Another Invalid Instance
This article’s second solution teaches you how to fix the invalid code using the same debugging principle. However, this instance only includes a few values and commands to confirm it can affect and destroy all applications and programs.
Henceforth, we will show you the invalid sample first, and then, we will exemplify the simple solution that debugs the code.
The attempted invalid code is shown in the following example:
values (1234567, ’19-JUN-22′, ’13-AUG-22 12:53 A.M.’);
Although everything appears functional, developers must check the date format and use the adequate date string conforming to the format.
As the former chapter explains, this clears your system and allows further code alterations. On the flip side, you can use the insert statement to provide the to_date function.
Repeat the next script to debug your system:
values (1234567,
to_date (’19-JUN-22′, ‘dd-mon-yy’),
to_date (’13-AUG-22 10:15 A.M.’, ‘dd-mon-yyyy hh:mi A.M.’));
In addition, this script forces Oracle to store the date and time information together, boosting your application’s performance.
Conclusion
The date format picture finishes before converting an entire input string error happens when the Oracle database has a string that does not match the driver’s expectations. Fortunately, we found several debugging principles and explained the following critical points:
- Professional developers refer to it as an ORA-01830 to_char Oracle error because it messes up the valid date format
- You can remake the invalid code exception by writing invalid date formats
- Locating the mistake allows developers to initiate the troubleshooting process
- This script provides two standard solutions that remove the error and enable further code alterations
- Programmers can apply the debugging principles to any broken command or property
Making mistakes and misspelling the date format is typical when working on large and complex projects. Luckily, this article provides the debugging methods, recreates the error, and teaches the commands that troubleshoot the script.

This is a runtime error. The date function has a problem to convert the date string. so display the date string to see what you want to convert:
select trunc(sysdate) || '13:00:00' from dual

to_date( trunc( sysdate ) || ’13:00:00′,’DD-MON-YY HH24:MI:SS’ )
An Innocent-looking query … but with nasty, implicit Type Conversions all over the place.
Breaking it down:
-
Start with sysdate(). (DATE Data Type)
-
Truncate that value, to remove the Time portion. (Still a DATE Data Type)
-
Implicitly cast that value into a VARCHAR, using whatever NLS_DATE_FORMAT happens to be in force, then concatenate the time bit on the end of that, without any intervening space to separate the two bits, and finally
-
Try to convert the resulting varchar value back into a DATE Data Type, using the explicit format given (which, by the way, includes a space between the data and Time portions).
If those internal conversions don’t give you something that exactly matches that Date/Time parsing pattern? Boom!
Remove the last to_date() call and see what [varchar] value you’re actually getting.
I suspect this will work if you remove the explicit Date/Time «pattern» and use whatever [NLS setting] the database is currently using.

ORA-01830
An Oracle operator can function across so many differing variables, statements, tables and datasets that keeping formatting straight can be one of the most difficult processes of all. Thankfully, Oracle is fairly clear in what it requires with formatting its data. Even when errors arise, the accompanying message tends to do a great job of specifying what exactly is at fault and gives the user a strong idea of where the error was emanating from and information on how to solve the formatting mistake.
The ORA-01830 complies with this concept, but the terminology it uses can seem a bit peculiar upon first viewing. So what do some of these terms mean, and how can a user utilize this information to make an educated correction to the error?
The Problem
The ORA-01830 error states the following message: “date format picture ends before converting entire input string”. These terms do not seemingly fall in line with phrases that are more typically associated with Oracle software. Let us break this phrase down to get a better idea of what it means.
The “date format picture” referenced in the error message is the format mask. If you are conducting an explicit conversion using the TO_DATE function, the format picture is the second argument in the function. For instance, if the argument states the following:
to_date (‘2015-01-01 11:59:99’, ‘YYYY-MM-DD’ )
The format picture in this example is the “YYYY-MM-DD” portion of the function. So what exactly is the issue with this function? The “coordinates” within the parentheses do not match. In other words, the information in the X side (‘2015-01-01 11:59:99’) cannot be formatted into the lead example on the Y side (these are not graphing coordinates but may be easier to think about in this manner). Specifically, the time reference (’11:59:99’) is not stated in the YYYY-MM-DD section and therefore has no format for Oracle to reference.
The cause of an ORA-01830 error message is stated in Oracle docs “a valid date format picture included extra data. The first part of the format picture was converted into a valid date, but the remaining data was not required.” Knowing what we know now, we can assume that the extra data in the above case was the time data set. The first part of the format picture that was successfully converted was the date format, which matches the Y set. In this particular case, the time information was not required.
At this point, the ORA-01830 may be a bit clearer: the formatting of an input string was off. What does a user do from here?
The Solution
The default date format in Oracle is typically DD-MON-YYYY. In order to correct the Oracle error, the user needs to edit the TO_DATE function to accommodate the extra information. Let us look at an example. Suppose that a user attempted to execute the following SQL statement:
INSERT INTO employer
VALUES
(1, ‘WALMART’, ’07-MAY-2015 7:23 PM’);
The user would then receive the following error message:
ORA-01830: date format picture ends before converting entire input string
Based off of what we went over in the last section, we now know that we need to accommodate the information “7:23 PM”. To do this, edit in the following method:
INSERT INTO employer
VALUES
(1, ‘WALMART’, TO_DATE(07-MAY-2015 7:23 PM’, ‘DD-MON-YYYY HH:MI PM’));
This should correct the error and allow the user to continue onward. As a note, other formatting issues, such as the X set listing seconds not listed in the Y or the month listed as “MON” the X and “MM” in the Y, can be corrected in the same manner.
Looking forward
As can be seen from the example juxtaposed against the message, the solution is much more user-friendly than the initial error message may let on. If you find other instances of errors causing a similar degree of frustration, or perhaps just need further clarification on formatting issues, a good next step would be to contact a trusted Oracle consultant for more information.
In my previous article I have already given multiple Oracle error description with its resolution. In this article I would like to focus on how to resolve ORA-01830 error with example. The key thing in oracle is when you require to insert or update data in the table level user needs to check the format of the specified column. Most of the times developers or database admin will make mistake in formatting the data while inserting and updating.
ORA-01830 Error message and Cause of the error
In this section I would like to give more information about the ORA-01830 error message with its cause. The error message will be like “ORA-01830: date format picture ends before converting entire input string”. We will check what exactly the cause of this error. First we can fragment the actual error message and check why exactly this error will come.
Date Format Picture : Which refers to the formatting of the date which is not in correct format. You can use to_Date function to change the format of the date. There are always two arguments in TO_DATE function and there might be mismatch in the format of the date.
Ends before converting entire input string : This means that there might be some error converting the date format.
The key cause for this error is the date format user is trying to enter did not match the correct date format of the specified table. The user needs to be careful about the format which the table or oracle engine is using.
As a User you should know the default date format of the oracle which is “DD-MON-YYYY”. You can easily resolve ORA-01830 error with changing the date format of source in TO_DATE function as per the date format set for that database. I would like to give the example for the same. Lets talk about employee table and you are trying to insert joining date for employee :
Step 1 : Error Scenario
INSERT INTO Employee
VALUES
(1, ‘AMIT’, ’07-JUN-2022 4:32 PM’);
The output will be :
ORA-01830: date format picture ends before converting entire input string
Step 2 : Check date format for the Oracle database with using the following statement
SELECT value FROM V$NLS_PARAMETERS WHERE parameter = ‘NLS_DATE_FORMAT’;
Step 3 : Resolution of error With using TO_DATE function
INSERT INTO Employee
VALUES
(1, ‘Amit’, TO_DATE(07-JUN-2022 4:32PM’, ‘DD-MON-YYYY HH:MI PM’));
The above statement will correct error because you are converting the date implicitly with using the TO_DATE function. There are sometimes you require to adjust the parameters which are HH, MM, or any other date parameters. These are above steps to resolve ORA-01830 error with real life example.
