问题 I'm trying to make a SELECT on multiple joined VARIANT columned tables. The main record is returned as DATA and all supporting information around it are made up of supporting joined tables returned as INCLUDED.

问题 Summary Span of Control is a count of how many employees report to a given manager. Direct and indirect report counts should be split into their own totals. Other counts are needed, including many vacancies for direct and indirect reports there are in the organisation. A manager is any position that has other positions reporting to it.

问题 For example - I create database and a table from cli and insert some data: CREATE DATABASE testdb CHARACTER SET 'utf8' COLLATE 'utf8_general_ci'; USE testdb; CREATE TABLE test (id INT, str VARCHAR(100)) TYPE=innodb CHARACTER SET 'utf8' COLLATE 'utf8_general_ci'; INSERT INTO test VALUES (9, 'some string'); Now I can do this and these examples do work (so - quotes don't affect anything it seems): SELECT * FROM test WHERE id = '9'; INSERT INTO test VALUES ('11', 'some string'); So - in these
