Since upgrade to 10.3.15 version, I have an issue with update table with trigger :
#1146 - Table 'xxx.index_table' doesn't exist

Here is an example to see the error :
{{DROP TABLE IF EXISTS index_table;

update data_table, master_table
set data_table.title = master_table.title
where data_table.id_master = master_table.id_master and
master_table.title is not null and id = 'a';}}
