To get the total number of rows in a MySQL database, you can use aggregate function SUM() along with inbuilt column TABLE_ROWS from INFORMATION_SCHEMA.TABLES.

The syntax is as follows?

SELECT SUM(TABLE_ROWS)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = database();

假設(shè)我們正在使用名為’sample’的數(shù)據(jù)庫。

現(xiàn)在我們將獲取MySQL數(shù)據(jù)庫中的總行數(shù)−

mysql> SELECT SUM(TABLE_ROWS)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = database();

登錄后復(fù)制

這將產(chǎn)生以下輸出−

+-----------------+
| SUM(TABLE_ROWS) |
+-----------------+
| 2043            |
+-----------------+
1 row in set (22.11 sec)

登錄后復(fù)制

以上就是我們可以獲得 MySQL 數(shù)據(jù)庫的總行數(shù)嗎？的詳細(xì)內(nèi)容，更多請關(guān)注www.92cms.cn其它相關(guān)文章！
