如果您正在搜索任何特定的列，您可以使用Like语句

ex:

SELECT * FROM sqlite_master where sql like('%LAST%')

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

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。

PRAGMA table_info(table_name);

会给你一个列有所有列名的列表。

     //Called when application is started. It works on Droidscript, it is tested
     function OnStart()
     {
     //Create a layout with objects vertically centered. 
     lay = app.CreateLayout( "linear", "VCenter,FillXY" );  

     //Create a text label and add it to layout.
     txt = app.CreateText( "", 0.9, 0.4, "multiline" )  
     lay.AddChild( txt );
     app.AddLayout(lay);

     db = app.OpenDatabase( "MyData" )  
  
     //Create a table (if it does not exist already).  
     db.ExecuteSql( "drop table if exists test_table" )
     db.ExecuteSql( "CREATE TABLE IF NOT EXISTS test_table " +  
       "(id integer primary key, data text, num integer)",[],null, OnError )  
        db.ExecuteSql( "insert into test_table values (1,'data10',100), 
        (2,'data20',200),(3,'data30',300)")
        //Get all the table rows.      
        DisplayAllRows("SELECT * FROM test_table");
        DisplayAllRows("select *, id+100 as idplus, 'hahaha' as blabla from 
        test_table order by id desc;") 
     }

//function to display all records 
function DisplayAllRows(sqlstring)  // <-- can you use for any table not need to 
                                //  know column names, just use a *
                                // example: 
{ 
//Use all rows what is in ExecuteSql  (try any, it will works fine)
db.ExecuteSql( sqlstring, [], OnResult, OnError ) 
} 
//Callback to show query results in debug.  
function OnResult( res )   
{  
var len = res.rows.length; 
var s = txt.GetText();

// This is the answer how to read column names from table:

for(var i = 0; i < len; i++ )   
{  
    var rows = res.rows.item(i) 
    for (var item in rows) 
        {
            s += "    " + rows[item] + "   ";
        }
    s+="\n\n";

//app.Alert(s);
txt.SetText( s )  
}  
//Callback to show errors.  
function OnError( msg )

   app.Alert( "Error: " + msg )
