Method 1: Use mysqldump -- no-data to export the SQL statement for creating the database and table, drop the database, create the database, execute the exported SQL file, and create the table. Method 2: generate sqlmysql-n-s information_schema-e "select Concat ('truncate table', table_name, ';') from tables where table_schema = 'eab12 '"
The output result is as follows: truncate table authgroupbindings;
Truncate table authgroups;
Truncate table authusers;
Truncate table corpbadcustominfo;
Truncate table corpsmsblacklisyinfo;
Truncate table corpsmsfilterinfo;
Truncate table corpsmsinfo;
Truncate table eabasereginfos;
Truncate table eacorpblob;
Truncate table eacorpinfo ;........ this improves: mysql-n-s information_schema-e "select Concat ('truncate table', table_name ,';') from tables where table_schema = 'ab12' "| MySQL eab12 clears all tables in eab12. However, if a foreign key exists, an error may be reported. Therefore, you also need to add-fmysql-n-s information_schema-e "select Concat ('truncate table', table_name ,';') from tables where table_schema = 'ab12' "| mysql-F eab12 is executed several times until no error is reported.
