How to query the table name in mysql? Brief analysis of methods

In the MySQL database, a database contains multiple data tables. When we perform query operations, we need to first determine the table name of the query. But in some cases, you may not know the table name, or you may need to view all table names in the database.

The following are solutions to the two cases of MySQL querying table names:

1. Querying all table names in a database

We may You need to view all table names in a database to better understand the table structure in the database. In the MySQL database, you can use the following SQL statement to query:

SHOW TABLES;

This SQL statement will return all table names in the database. The execution result is similar to the following form:

+--------------------------+
| Tables_in_database_name  |
+--------------------------+
| table1                   |
| table2                   |
| table3                   |
+--------------------------+

Among them, all the table names under the "Tables_in_database_name" column are all the table names in the database.

2. Query the table name of a certain data table

When querying the data table, we need to know the table name of the data table, and we need to ensure that the table name exists in the specified database. In the MySQL database, use the following SQL statement to query:

SELECT TABLE_NAME
FROM information_schema.tables
WHERE table_schema = 'database_name' AND table_name = 'specific_table_name';

In executing the above SQL statement, you need to replace "database_name" with the actual specified database name and "specific_table_name" with the table that actually needs to be queried. name. If the query is successful, the SQL statement will return results similar to the following:

+------------------+
| TABLE_NAME       |
+------------------+
| specific_table_name |
+------------------+

Among them, the content under the "TABLE_NAME" column is the name of the table to be queried.

To sum up, when we query the table name in MySQL, we can query through the above two methods, and choose according to actual needs. At the same time, when querying table names, the SQL statements need to be spelled and written correctly to avoid errors.
