                问题描述

                我想知道是否可以找到表中的行数和列数.

                I would like to know if it's possible to find the number of both rows and columns within a table.

                SELECT COUNT(*)
                FROM tablename
                

                推荐答案

                SELECT COUNT(*)
                  FROM INFORMATION_SCHEMA.COLUMNS
                 WHERE table_catalog = 'database_name' -- the database
                   AND table_name = 'table_name'
