WKB_PARSE_ERROR error class

SQLSTATE: 22023

Error parsing WKB: <parseError> at position <pos>

Parameters

• parseError: Description of the kind of parse error encountered.
• pos: The 1-based position in the WKB binary string where the parse error occurred.

Explanation

Some geospatial functions may return this error when parsing the input, that is expected to be in well-known binary (WKB) format.

Examples

-- Feeding an empty geometry collection in WKB format into the h3_polyfillash3string function (as opposed to a polygon or multipolygon).
> SELECT h3_polyfillash3string(unhex('010700000000'), 8)
  [WKB_PARSE_ERROR] Error parsing WKB: Invalid or unsupported type 7 at position 2

-- The input WKB corresponds to a polygon with 5 vertices in the exterior ring, but only 4 vertices are present in the description.
> SELECT h3_polyfillash3(unhex('0103000000010000000500000050fc1873d79a5ec0d0d556ec2fe342404182e2c7988f5dc0f46c567dae064140aaf1d24d628052c05e4bc8073d5b444050fc1873d79a5ec0d0d556ec2fe34240'), 2)
  [WKB_PARSE_ERROR] Error parsing WKB: Unexpected end of WKB buffer at position 78
