Let us learn how to remove the error 23502 PostgreSQL not null violation auto increment with the support of our PostgreSQL support services at Bobcares.

Error: 23502 PostgreSQL not null violation auto increment

When we attempt to insert a row into a PostgreSQL table with an auto incrementing column with a not null constraint and fail to give a value for that column, the error “23502 PostgreSQL not null violation auto increment” frequently occurs.

Error Breakdown: 23502 not null violation auto increment

• PostgreSQL:

  PostgreSQL is a strong relational database management system (RDBMS) that is open source. Known for its dependability and flexibility and supports a wide range of features and data types.
• Auto-incrementing column:

  A serial or identity data type can build an auto-incrementing column in PostgreSQL.”. It produces a unique value for each new row added to the database, making sure that each row has a unique value in that column.
• Not-null constraint:

  A not-null constraint is a database constraint that prevents a column from having an empty (null) value. During the insertion of a new row, we must give a non-null value for the column.

The “23502 PostgreSQL not null violation auto increment” error indicates that we attempted to insert a row into a table with an auto-incrementing column with a not-null constraint but did not give a value for that column.

Error: 23502 not null violation auto increment: Solution

We have a couple alternatives for dealing with this problem:

• Give the auto-incrementing column a specific value:

  Instead of depending on the auto increment technique, we may manually set a value for the column during insertion. Check if the supplied value is unique and follows any other restrictions set for the column.
• Modify the table definition:

  Secondly, we must change the table definition if we want the auto-incrementing column to create data automatically.

  Check to see that the column has the right data type (serial or identity) and the relevant constraints, such as the auto-increment behavior and the not-null requirement.
• Check the insert statement:

  FInally, check the insert statement we’re using to make sure we’re supplying the values for all columns. This includes the auto-incrementing column, accurately.

  In the insert statement, ensure that the column is not accidentally excluded or set to null.

We should be able to overcome the “23502 PostgreSQL not null violation auto increment” problem and properly insert rows into the table with an auto incrementing column and not null constraint by addressing these points.
