sql - List of table names ordered by their foreign key dependency in MySQL -


given mysql database, how obtain list of table names ordered foreign key dependency can delete each table? understand foreign key's stored in key_column_usage table i'm not sure if there utility method obtain table names in correct order. prefer 100% sql solution.

if foreign keys follow naming convention (as should :), simple like

select table_name, group_concat(distinct constraint_name order constraint_name) fk_list   information_schema.key_column_usage  constraint_name rlike 'fk' group  table_name order  fk_list, table_name;

or, if foreign keys don't follow naming convention, then

select table_name, group_concat(distinct constraint_name order constraint_name) fk_list   information_schema.key_column_usage  referenced_table_name not null group  table_name order  fk_list, table_name;

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
