zero length character string
What this means
SQLSTATE 2200F is raised when a zero-length (empty) string is provided in a context that explicitly requires a non-empty string — for example, some character-type functions or specific domain constraints.
Why it happens
- 1Passing an empty string to a function or context that requires at least one character
How to reproduce
Empty string where non-empty is required.
expected output
ERROR: zero-length delimited identifier
Fix
Validate that the string is non-empty before use
WHEN When accepting string values from user input or external sources.
Validate that the string is non-empty before use
SELECT NULLIF(input_col, '') FROM data;
Why this works
NULLIF converts empty strings to NULL, which can then be handled via COALESCE or a default value.
