To reset a dynamic sequence in PostgreSQL, you can use the SETVAL function to set the current value of the sequence to a specified value. The syntax for resetting a sequence is:
1
|
SELECT setval('sequence_name', new_value, false);
|
Replace sequence_name with the name of the sequence you want to reset, and new_value with the desired starting value for the sequence. The third parameter (false) indicates that the sequence should be reset without incrementing the current value.
For example, to reset a sequence named my_sequence to start from 1, you would run the following query:
1
|
SELECT setval('my_sequence', 1, false);
|
This will reset the sequence my_sequence to start from 1 the next time it is used.

How to reset the access privileges of a sequence in PostgreSQL?
To reset the access privileges of a sequence in PostgreSQL, you can use the following command:
1 2 |
REVOKE ALL ON SEQUENCE sequence_name FROM public; GRANT ALL ON SEQUENCE sequence_name TO public; |
Replace sequence_name with the name of the sequence for which you want to reset the access privileges.
This command will revoke all privileges on the sequence for the public role, and then grant all privileges back to the public role. This will reset the access privileges of the sequence to the default settings.
How to reset the owner value of a sequence in PostgreSQL?
To reset the owner value of a sequence in PostgreSQL, you can use the ALTER SEQUENCE command. Here is an example of how to reset the owner value of a sequence:
1
|
ALTER SEQUENCE sequence_name OWNED BY new_owner;
|
Replace sequence_name with the name of the sequence you want to reset the owner value for and new_owner with the new owner of the sequence.
For example, if you have a sequence named my_sequence and you want to set the owner to new_user, you would run the following command:
1
|
ALTER SEQUENCE my_sequence OWNED BY new_user;
|
This command will reset the owner value of the sequence to the specified user.
How to reset a sequence in PostgreSQL to a specific value?
To reset a sequence in PostgreSQL to a specific value, you can use the setval() function. Here's an example of how to do it:
1
|
SELECT setval('your_sequence_name_here', your_specific_value, true);
|
Replace 'your_sequence_name_here' with the name of your sequence, and replace 'your_specific_value' with the specific value you want the sequence to be reset to.
For example, if you have a sequence named 'seq_id' and you want to reset it to 1000, you would run the following SQL query:
1
|
SELECT setval('seq_id', 1000, true);
|
This will reset the sequence 'seq_id' to start from 1000.
What is the command to reset a sequence in PostgreSQL?
To reset a sequence in PostgreSQL, you can use the following command:
ALTER SEQUENCE sequence_name RESTART WITH new_start_value;
Replace "sequence_name" with the name of the sequence you want to reset, and "new_start_value" with the value that you want the sequence to start from.
How to reset the restart value of a sequence in PostgreSQL?
To reset the restart value of a sequence in PostgreSQL, you can use the setval() function. Here's an example of how you can do this:
1 2 3 4 5 |
-- Reset the restart value of a sequence named my_sequence to 1 SELECT setval('my_sequence', 1); -- Alternatively, you can also use the following syntax -- SELECT setval('my_sequence', 1, false); |
Replace 'my_sequence' with the name of the sequence that you want to reset. The second argument is the new value that you want to set the sequence to. The third argument determines whether the next value to be returned by the sequence is the specified value or the default start value of the sequence. Use TRUE to set the next value to the specified value, and FALSE to set it to the default start value.
After running the setval() function on your sequence, the next value returned by the sequence will be the specified value.
