![]() ![]() ![]() We can even get a bit fancier and convert the normal size values from bytes into something more useful and understandable to most people like megabytes. INDEX_LENGTH is the length (or size) of the index file for the table (also in bytes).Īrmed with this information, we can execute a query that will list all tables in a specific database along with the disk space (size) of each.DATA_LENGTH is the length (or size) of all data in the table (in bytes).List Table Sizes From a Single DatabaseĪs can seen in the official documentation, the INFORMATION_SCHEMA.TABLES table contains around 20 columns, but for the purpose of determining the amount of disk space used by tables, we’ll focus on two columns in particular: DATA_LENGTH and INDEX_LENGTH. For our purposes we’re particularly interested in the tables metadata, which we can query to actually extract the size of various tables in the system. Everything from views and user_privilieges to columns and tables can be found in the INFORMATION_SCHEMA. To find the size of each user-created database, run the following query: mysql> SELECT tableschema, ROUND(SUM(datalength+indexlength)/1024/1024/1024,2) size. Regardless of the name, what matters is the information provided by these INFORMATION_SCHEMA tables. This usage is intense for a shared server. Their disk is 30GB which 2 GB is their website files and 15GB their database. Sometimes we have users who abuses the hell out of the account. While most other databases refer to this information as a catalog, the official MySQL documentation refers to the INFORMATION_SCHEMA metadata as tables. But I am wondering how can I set a limit for mysql database size for customers. The databases are ordered in alphabetical order. MySQL returns the results in a table with one columnDatabase. Like most relational databases, MySQL provides useful metadata about the database itself. Run the following query to show list of databases: SHOW DATABASES You can run this statement from MySQL Command Line Client, MySQL Shell, as well as from any GUI tool that supports SQLfor example, dbForge Studio for MySQL. ![]()
