I have the following query:
SELECT * FROM
JSON_TABLE(
'{"TrackingIds":[-1,-2],"Matrices":[22,23]}'
,"$" COLUMNS(
NESTED path "$.Matrices[*]" COLUMNS (Matrices INT path '$'),
NESTED path "$.TrackingIds[*]" COLUMNS (TrackingId INT path '$')
)) AS j;
Which yields:
Matrices TrackingId
22 \N
23 \N
\N -1
\N -2
How would I get it produce the below:
Matrices TrackingId
22 -1
23 -2
Almost like it is a Key Value lookup. Thanks, -Tanner
This is by design. From the MySQL 8 manual :
Sibling nested paths—that is, two or more instances of NESTED [PATH] in the same COLUMNS clause—are processed one after another, one at a time. While one nested path is producing records, columns of any sibling nested path expressions are set to NULL. This means that the total number of records for a single match within a single containing COLUMNS clause is the sum and not the product of all records produced by NESTED [PATH] modifiers.
You need an outer query to group related rows together, or not use NESTED PATH
