. schema table_name

这将从数据库中列出表的列名。

希望这能有所帮助!!

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

    sqlite3_stmt *sqlStatement;

    NSMutableArray *result = [NSMutableArray array];

    const char *sql = [[NSString stringWithFormat:@"PRAGMA table_info('%@')",table] UTF8String];

    if(sqlite3_prepare(md.database, sql, -1, &sqlStatement, NULL) != SQLITE_OK)

    {
        NSLog(@"Problem with prepare statement tableInfo %@",
                [NSString stringWithUTF8String:(const char *)sqlite3_errmsg(md.database)]);

    }

    while (sqlite3_step(sqlStatement)==SQLITE_ROW)
    {
        [result addObject:
          [NSString stringWithUTF8String:(char*)sqlite3_column_text(sqlStatement, 1)]];
    }

    return result;
}

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

当你运行sqlite3命令行时，输入:

sqlite3 -header

也会给你想要的结果吗

如果有的话

.headers ON

你会得到你想要的结果。

获取一个表和列的列表作为视图:

CREATE VIEW Table_Columns AS
SELECT m.tbl_name AS TableView_Name, m.type AS TableView, cid+1 AS Column, p.*
FROM sqlite_master m, Pragma_Table_Info(m.tbl_name) p
WHERE m.type IN ('table', 'view') AND
   ( m.tbl_name = 'mypeople' OR m.tbl_name LIKE 'US_%')   -- filter tables
ORDER BY m.tbl_name;
