How to diagnose and fix the 22003 numeric_value_out_of_range error code in Postgres.

by

The 22003 error code in PostgreSQL, which stands for numeric_value_out_of_range, occurs when a number is too large to be stored in the data type specified by the column. This can happen with various numeric types such as integers, floating-point numbers, or numerics with a specified precision and scale.

To diagnose and fix this issue, you should:

  1. Check the data type of the column where you are trying to insert or update the value. Ensure that the numeric value is within the allowable range for that data type.
  2. If necessary, change the data type of the column to a larger range numeric type. For example, if you are exceeding the range of an integer, you might need to use a bigint or numeric type.
  3. If you are performing calculations that result in the error, ensure that intermediate results do not exceed the maximum values for the data type.

Here are some examples of problematic operations and how to correct them:

Problematic Operation with Integer:

-- This will throw the 22003 error since 2147483648 is greater than the maximum value for integer
INSERT INTO example_table (integer_column) VALUES (2147483648);

Corrected Operation with Integer:

-- Changing the column to use bigint
ALTER TABLE example_table ALTER COLUMN integer_column TYPE bigint;
INSERT INTO example_table (integer_column) VALUES (2147483648);

Problematic Operation with Numeric:

-- This might throw the 22003 error if the precision of the numeric column is exceeded
INSERT INTO example_table (numeric_column) VALUES (12345678901234567890);

Corrected Operation with Numeric:

-- Changing the column to have a larger precision
ALTER TABLE example_table ALTER COLUMN numeric_column TYPE numeric(30);
INSERT INTO example_table (numeric_column) VALUES (12345678901234567890);

Problematic Operation with Computation:

-- Assuming integer_column is an integer type, this will throw the 22003 error
UPDATE example_table SET integer_column = integer_column * 10;

Corrected Operation with Computation:

-- First, change the column to a larger numeric type
ALTER TABLE example_table ALTER COLUMN integer_column TYPE bigint;
UPDATE example_table SET integer_column = integer_column * 10;

Information on the 22003 error code can be found in the official PostgreSQL documentation, and practical examples of this error being triggered and addressed are available on resources such as Stack Overflow.

When encountering the 22003 error, you’ll need to examine the specific context in which the error is occurring and adjust the numeric types and values accordingly to ensure they are within the acceptable range.
