如果你想要查询的输出包含列名并正确对齐为列，可以在sqlite3中使用这些命令:

.headers on
.mode column

你会得到如下输出:

sqlite> .headers on
sqlite> .mode column
sqlite> select * from mytable;
id          foo         bar
----------  ----------  ----------
1           val1        val2
2           val3        val4

如果你有sqlite数据库，使用sqlite3命令行程序和这些命令:

列出数据库中所有的表。

.tables

要显示给定表名的模式:

.schema tablename

在Python中使用sqlite3

顶部答案PRAGMA table_info()返回一个元组列表，可能不适合进一步处理，例如:

[(0, 'id', 'INTEGER', 0, None, 0),
 (1, 'name', 'TEXT', 0, None, 0),
 (2, 'age', 'INTEGER', 0, None, 0),
 (3, 'profession', 'TEXT', 0, None, 0)]

在Python中使用sqlite3时，只需在最后添加一个列表推导式，以过滤掉不需要的信息。

import sqlite3 as sq

def col_names(t_name):
    with sq.connect('file:{}.sqlite?mode=ro'.format(t_name),uri=True) as conn:
        cursor = conn.cursor()
        cursor.execute("PRAGMA table_info({}) ".format(t_name))
        data = cursor.fetchall()
        return [i[1] for i in data]

col_names("your_table_name")

结果

["id","name","age","profession"]

免责声明:请勿在生产环境中使用，因为此代码段可能会受到SQL注入的影响!

//JUST little bit modified the answer of giuseppe  which returns array of table columns
+(NSMutableArray*)tableInfo:(NSString *)table{

txt.SetText( s )

//Callback to show errors.  
function OnError( msg )

我知道已经太迟了，但这会帮助其他人。

要找到表的列名，您应该执行select * from tbl_name，您将得到sqlite3_stmt *格式的结果。并检查列对所获取的总列的迭代。请参考以下代码相同。

// sqlite3_stmt *statement ;
int totalColumn = sqlite3_column_count(statement);
for (int iterator = 0; iterator<totalColumn; iterator++) {
   NSLog(@"%s", sqlite3_column_name(statement, iterator));
}

这将打印结果集的所有列名。
