There are two editions of MySQL Workbench: the community edition and the commercial edition. To get started with the MySQL database, check the MySQL Tutorial website. However, knowledge in relational databases and database design may be required. It requires no prior knowledge of MySQL Workbench. This article is suitable for beginner to intermediate MySQL Workbench users. This tutorial will cover database design and modeling with MySQL Workbench. See MySQL’s documentation for a full list of options.MySQL Workbench is a graphical visual database design tool with multiple functionalities. This utility accepts quite a few options, such as -user (so that you can pass the username), -password (so that you can pass the password), -host for the host on which MySQL server is located, etc. If you get an “access denied” error, you may need to use sudo, and enter your password at the prompt: sudo mysqlshow music If no column is given, all matching columns and column types in the table are shown. If no table is given, all matching tables in the database are shown. If no database is given, a list of database names is shown. The output displays only the names of those databases, tables, or columns for which you have some privileges. To use this option, open a command line prompt/terminal window and run the following (replacing music with the database you’re interested in): mysqlshow music The mysqlshow ClientĪnother way to do it is with the mysqlshow utility. Similarly, querying it without filtering by TABLE_TYPE returns all table types. Querying this without filtering the results by TABLE_SCHEMA returns tables from all databases. TABLE_SCHEMA LIKE 'Music' AND TABLE_TYPE LIKE 'BASE_TABLE' We can also query the information_schema.TABLES table: SELECT | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment | It also accepts a WHERE and LIKE clause, like SHOW TABLES. The SHOW TABLE STATUS command is similar to the SHOW TABLES command but provides more extensive information about each (non- TEMPORARY) table. In this case I returned all tables that start with the letter a. SHOW TABLES also accepts a LIKE clause that can be used to narrow the results to just those tables that match a given pattern: SHOW TABLES If we only want base tables to be returned, we can use a WHERE clause against the Table_type column: SHOW FULL TABLES We can see that most of the results listed here are actually views. We can also use the FULL modifier to return a second column that displays the type: SHOW FULL TABLES That listed all tables in the current database, which is called Music. The SHOW TABLES command lists the non- TEMPORARY tables and views in a given database: SHOW TABLES Below are four ways to list out the tables in a MySQL database using SQL or the command line.
