查询所有数据库占用磁盘空间大小的SQL语句：
代码如下:select TABLE_SCHEMA, concat(truncate(sum(data_length)/1024/1024,2),’ MB’) as data_size,concat(truncate(sum(index_length)/1024/1024,2),’MB’) as index_sizefrom information_schema.tablesgroup by TABLE_SCHEMAorder by data_len
1.查询当前数据库所有表
代码如下:SELECT O.object_id AS TableId, TableName=O.name , TableDesc= O.type FROM sys.columns C INNER JOIN sys.objects O ON C.[object_id]=O.[object_id] AND O.type=’U’ AND O.is_ms_shipped=0 INNER
本文实例讲述了Python获取SQLite查询结果表列名的方法。分享给大家供大家参考，具体如下：
获得查询结果表的列名：
db = sqlite.connect('data.db')
cur = db.cursor()
cur.execute("select * from table")
col_name_list = [tuple[0] for tuple in cur.descr iption]
print col_name_list
获得所有列名：
cur.execute("PRAG
