I have a MySql Query that is rewritten by the wpdatatable GUI when pressing save and is not valid anymore.
My SQL uses a NATURAL LEFT JOIN to produce a summary of two columns and a procentage differance, In my sql progam the SQL is OK, byt when i put it into WPdatatables and press sage the "NATURAL" is dropped from the sql. Is this a bug or some feature that can be configured?
Original SQL:
SELECT SANKTION.Jurisdiction, SANKTION.Gruppering, count( DISTINCT SANKTION.Sanktion_timestamp ) AS Totalt_Antal, count( DISTINCT SANKTION_KOMPONENT.Sanktion_timestamp ) AS Behandlat_Antal, count( DISTINCT SANKTION_KOMPONENT.Sanktion_timestamp ) / count( DISTINCT SANKTION.Sanktion_timestamp ) * 100 AS pct FROM SANKTION NATURAL LEFT JOIN SANKTION_KOMPONENT GROUP BY SANKTION.Jurisdiction ORDER BY pct DESC
SQL generated from wpdatatable:
SELECT SANKTION.Jurisdiction, SANKTION.Gruppering, count( DISTINCT SANKTION.Sanktion_timestamp ) Totalt_Antal, count( DISTINCT SANKTION_KOMPONENT.Sanktion_timestamp ) Behandlat_Antal, count( DISTINCT SANKTION_KOMPONENT.Sanktion_timestamp ) / count( DISTINCT SANKTION.Sanktion_timestamp ) * 100 pct FROM SANKTION LEFT JOIN SANKTION_KOMPONENT GROUP BY SANKTION.Jurisdiction ORDER BY pct DESC LIMIT 10
Unfortunately, since wpDataTables is not a database management plugin, and is using a 3rd party PHP SQL parser, it's not expected that it works correctly with all statements you add.
Our logic is based on a PHP SQL parser which has full support for the SQL dialect for the following statement types
Filtering, sorting, and search may not work properly if you include:
Accent graves ( ` ) around the table name
JOIN functions
UNION functions
CONCAT functions
sub-queries
You can try preparing a MySQL view (which will return the data that you need, call it e.g. “view1” and then build a wpDataTables based on a simple query like "SELECT * FROM view1″.

Hello Fredrik.
Unfortunately, since wpDataTables is not a database management plugin, and is using a 3rd party PHP SQL parser, it's not expected that it works correctly with all statements you add.
Our logic is based on a PHP SQL parser which has full support for the SQL dialect for the following statement types
SELECT, INSERT, UPDATE, DELETE, REPLACE, RENAME, SHOW, SET, DROP, CREATE INDEX, CREATE TABLE, EXPLAIN and DESCRIBE.
Some of them are disabled for security reasons.
Filtering, sorting, and search may not work properly if you include:
