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;

下面的命令设置列名:

.header on

然后，它是这样的:

sqlite> select * from user;
id|first_name|last_name|age
1|Steve|Jobs|56
2|Bill|Gates|66
3|Mark|Zuckerberg|38

下面的命令取消设置列名:

.header off

然后，它是这样的:

sqlite> select * from user;
1|Steve|Jobs|56
2|Bill|Gates|66
3|Mark|Zuckerberg|38

这些命令显示了".header"命令的详细信息:

.help .header

Or:

.help header

然后，它是这样的:

sqlite> .help .header
.headers on|off          Turn display of headers on or off

此外，下面的命令设置输出模式“box”:

.mode box

然后，它是这样的:

sqlite> select * from user;
┌────┬────────────┬────────────┬─────┐
│ id │ first_name │ last_name  │ age │
├────┼────────────┼────────────┼─────┤
│ 1  │ Steve      │ Jobs       │ 56  │
│ 2  │ Bill       │ Gates      │ 66  │
│ 3  │ Mark       │ Zuckerberg │ 38  │
└────┴────────────┴────────────┴─────┘

并且，下面的命令设置输出模式“table”:

.mode table

然后，它是这样的:

sqlite> select * from user;
+----+------------+------------+-----+
| id | first_name | last_name  | age |
+----+------------+------------+-----+
| 1  | Steve      | Jobs       | 56  |
| 2  | Bill       | Gates      | 66  |
| 3  | Mark       | Zuckerberg | 38  |
+----+------------+------------+-----+

这些命令显示了命令".mode"的详细信息:

.help .mode

Or:

.help mode

然后，它是这样的:

sqlite> .help .mode
.import FILE TABLE       Import data from FILE into TABLE
   Options:
     --ascii               Use \037 and \036 as column and row separators
     --csv                 Use , and \n as column and row separators
     --skip N              Skip the first N rows of input
     --schema S            Target table to be S.TABLE
     -v                    "Verbose" - increase auxiliary output
   Notes:
     *  If TABLE does not exist, it is created.  The first row of input
        determines the column names.
     *  If neither --csv or --ascii are used, the input mode is derived
        from the ".mode" output mode
     *  If FILE begins with "|" then it is a command that generates the
        input text.
.mode MODE ?OPTIONS?     Set output mode
   MODE is one of:
     ascii       Columns/rows delimited by 0x1F and 0x1E
     box         Tables using unicode box-drawing characters
     csv         Comma-separated values
     column      Output in columns.  (See .width)
     html        HTML <table> code
     insert      SQL insert statements for TABLE
     json        Results in a JSON array
     line        One value per line
     list        Values delimited by "|"
     markdown    Markdown table format
     qbox        Shorthand for "box --width 60 --quote"
     quote       Escape answers as for SQL
     table       ASCII-art table
     tabs        Tab-separated values
     tcl         TCL list elements
   OPTIONS: (for columnar modes or insert mode):
     --wrap N       Wrap output lines to no longer than N characters
     --wordwrap B   Wrap or not at word boundaries per B (on/off)
     --ww           Shorthand for "--wordwrap 1"
     --quote        Quote output text as SQL literals
     --noquote      Do not quote output text
     TABLE          The name of SQL table used for "insert" mode

要获得列的列表，您可以简单地使用:

.schema tablename

-(NSMutableDictionary*)tableInfo:(NSString *)table
{
  sqlite3_stmt *sqlStatement;
  NSMutableDictionary *result = [[NSMutableDictionary alloc] init];
  const char *sql = [[NSString stringWithFormat:@"pragma table_info('%s')",[table UTF8String]] UTF8String];
  if(sqlite3_prepare(db, sql, -1, &sqlStatement, NULL) != SQLITE_OK)
  {
    NSLog(@"Problem with prepare statement tableInfo %@",[NSString stringWithUTF8String:(const char *)sqlite3_errmsg(db)]);

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

  }

  return result;
  }

我知道这是一个旧的帖子，但最近我需要同样的帖子，并找到了一个简洁的方法:

SELECT c.name FROM pragma_table_info('your_table_name') c;

我能够通过使用一个sql查询检索具有相应列的表名，但列输出是逗号分隔的。我希望它能帮助到一些人

SELECT tbl_name, (SELECT GROUP_CONCAT(name, ',') FROM PRAGMA_TABLE_INFO(tbl_name)) as columns FROM sqlite_schema WHERE type = 'table';
