Question

谁能告诉我如何在 MySQL 中获取 table 的主键？

Answer 1

试试这个：

解决方案一：

这是来自Ajons Answer

SELECT k.COLUMN_NAME
FROM information_schema.table_constraints t
LEFT JOIN information_schema.key_column_usage k
USING(constraint_name,table_schema,table_name)
WHERE t.constraint_type='PRIMARY KEY'
    AND t.table_schema=DATABASE()
    AND t.table_name='owalog';

方案二：

这是来自alexn

SHOW KEYS FROM tablename WHERE Key_name = 'PRIMARY'

方案三：

SHOW INDEX FROM presort.final_conf_score_mld_run2 
WHERE Key_name = 'PRIMARY';
