问题 I have a quite complicated data structure that lies in several tables. I have a function that makes a copy of that structure. I want to make a copy and get newly created data in a single query like this: SELECT * FROM main_table JOIN other_table ON (main_table.id = other_table.main_id) WHERE main_table.id = make_copy(old_id); The copy is successfully created, but is not returned by the above query. I guess it is not yet visible for the outer query or somehow committed . I have also tried to

问题 I am wanting to use CTE so I updated to MariaDB 10.2.20. phpMyAdmin is giving an error on the use of "WITH". I am not able to find why "WITH" is not supported in this version.

MariaDB starting with 10.2.2 Recursive WITH has been supported since MariaDB 10.2.2. https://mariadb.com/kb/en/library/with/ 回答1: It looks like a bug in phpMyAdmin, see this open bug since August 2017: https://github.com

问题 I have an "insert only" database, wherein records aren't physically updated, but rather logically updated by adding a new record, with a CRUD value, carrying a larger sequence. In this case, the "seq" (sequence) column is more in line with what you may consider a primary key, but the "id" is the logical identifier for the record. In the example below, This is the physical representation of the table: seq id name | CRUD | ----|-----|--------|------| 1 | 10 | john | C | 2 | 10 | joe | U | 3 |
