PostgreSQL error 22000 is a generic data_exception raised when input data is invalid, out of range, or malformed for the requested operation.
PostgreSQL Error 22000 (data_exception) appears when supplied data is invalid for the requested operation, such as out-of-range numbers or malformed dates. Validate and cast your inputs, enforce correct types, and sanitize user data to resolve the issue.
PostgreSQL Error 22000
PostgreSQL returns error code 22000, labeled data_exception, when supplied data is invalid, out of range, or malformed for the operation being executed.
The code belongs to SQLSTATE class 22, covering all data exceptions, so the accompanying text explains the exact problem - for example, "invalid text representation" or "division by zero".
Invalid input values cause this error.
Typical triggers include strings that cannot be cast to numbers, dates outside supported ranges, division by zero, and numeric overflow.
Functions that expect well-formed data, such as regexp_matches, also raise 22000 if the provided pattern is invalid.
Identify the precise sub-code or message text shown with 22000.
Once you know whether it is "invalid text representation" or similar, validate and transform incoming data before executing the query.
Use explicit CASTs, check constraints, and WHERE filters to prevent bad rows from reaching calculations. Wrap risky operations in CASE expressions to guard against zero denominators.
Scenario: casting a non-numeric string to integer.
Solution: run SELECT * FROM table WHERE value !~ '^[0-9]+$' to locate bad rows, then fix or filter them.
Scenario: division by zero in an analytics query.
Solution: change expr/NULLIF(denominator,0) to avoid the exception.
Sanitize user input before insertion, enforce strict domain constraints, and add CHECK constraints that reject invalid values at write time.
Instrument queries in Galaxy's editor with real-time result previews and AI suggestions to catch casting issues early during development.
22012 division_by_zero - raised when denominator evaluates to zero. Avoid by using NULLIF.
22P02 invalid_text_representation - triggered by malformed literals. Validate and cleanse input.
.
Yes. The error indicates that supplied data is invalid or cannot be processed in its current form.
Set client_min_messages = NOTICE and examine the ERROR line returned by PostgreSQL, which includes the five-character SQLSTATE.
Galaxy's real-time validation and AI copilot highlight probable casting or division issues, reducing the likelihood of runtime 22000 errors.
Explicit casting clarifies intent but will still raise 22000 if the source value is invalid. Validate or sanitize inputs first.
