SELECT
	C.TABLE_SCHEMA AS '数据库名',
	C.TABLE_NAME AS '表名',
	C.COLUMN_NAME AS '字段名',
	C.COLUMN_TYPE AS '数据类型',
	C.IS_NULLABLE AS '允许为空',
	C.COLUMN_COMMENT AS '字段说明'
FROM
	COLUMNS C
INNER JOIN TABLES T ON C.TABLE_SCHEMA = T.TABLE_SCHEMA
AND C.TABLE_NAME = T.TABLE_NAME
WHERE
	T.TABLE_SCHEMA = 'xxx'
--and T.TABLE_NAME='tableName' 
--xxx这里为数据库名
