When encountering the error "2201G: Invalid Argument for Width Bucket Function" in PostgreSQL, the user should take the following immediate actions to investigate and potentially resolve the issue:
SELECT * FROM pg
catalog.pgstatactivity WHERE state = 'active';width_bucket
function usage within the identified query. The width_bucket
function has the following form:width_bucket(operand, b1, b2, count)
operand
, b1
, b2
, and count
are provided correctly. b1
should be less than b2
, and count
must be a positive integer.operand
, b1
, b2
, and count
to ensure they are within expected ranges. For example:SELECT operand, b1, b2, count FROM your_table WHERE <your_condition>;
b1
< b2
and count
is a positive integer.operand
, b1
, b2
, and count
based on the data types and expected values you’re working with. For example:SELECT width_bucket(10, 1, 100, 10);
operand
, b1
, b2
, and count
are compatible with the width_bucket
function. Use the pg_typeof
function to check data types, e.g.:SELECT pg
typeof
(operand), pgtypeof(b1), pg
typeof
(b2), pgtypeof(count) FROM your
table
WHERE <yourcondition>;
width_bucket
function to ensure correct usage and understand the constraints.width_bucket
function.These steps are directly actionable and should help in identifying and fixing the cause of the "2201G: Invalid Argument for Width Bucket Function" error in PostgreSQL.
