PostgreSQL raises this error when the OFFSET or FETCH clause receives a negative or non-numeric row count.
invalid_row_count_in_result_offset_clause appears when PostgreSQL finds a negative or non-numeric number in the OFFSET or FETCH FIRST/NEXT clause. Supply a non-negative integer or bind parameter to resolve the error.
invalid_row_count_in_result_offset_clause
PostgreSQL error code 2201X signals that the server rejected the value supplied to the OFFSET or FETCH clause because it is not a valid non-negative integer.
The parser stops execution at the offending statement, returning the error before any data is read or written.
Fixing the row count lets the query proceed normally.
A negative literal such as OFFSET -5 violates the SQL standard, triggering the error instantly.
Passing a text parameter or a NULL instead of a numeric value also produces the same error code.
Expressions that evaluate to a negative number at runtime, for example OFFSET (SELECT -1), are caught when the query is executed.
Always provide a non-negative integer to OFFSET or FETCH.
Replace hard-coded negatives with 0 or a valid positive number.
If you use bind variables, validate them in application code or cast them to integer and apply GREATEST(value,0) in SQL.
When dynamic SQL is unavoidable, COALESCE the parameter to 0 to guarantee a safe default.
Pagination APIs sometimes forward pageNumber * pageSize as OFFSET.
Guard against pageNumber < 0 on the server side.
Mistyped LIMIT and OFFSET order (OFFSET 10 LIMIT 5) is legal, but swapping numbers accidentally can send OFFSET -5. Re-check variable mapping.
ORM libraries may pass NULL for optional pagination.
Set the default to 0 or exclude OFFSET entirely.
Use CHECK constraints or DOMAINs for pagination parameters in stored procedures to block negative inputs.
Leverage Galaxy’s static analysis: the editor flags negative OFFSET literals before you run the statement, saving a round-trip to the server.
Add automated tests that hit edge cases like page 0, page -1, and very large offsets.
2201W invalid_row_count_in_result_limit_clause occurs when LIMIT receives an illegal value.
Fix by supplying a non-negative integer.
42601 syntax_error appears when OFFSET or LIMIT keywords are misspelled. Correct the spelling.
42P01 undefined_table arises if the query references a table that does not exist. Check schema names and search_path.
.
Yes. PostgreSQL treats the absence of an OFFSET clause the same as OFFSET 0.
No. The rule applies across all supported versions, though the exact wording of the message is stable from 9.6 onward.
No. LIMIT and OFFSET are validated independently. Both must receive non-negative integers.
Galaxy’s editor parses SQL locally, flags negative offsets, and its AI copilot can auto-correct the clause before execution.
