(4 answers)
Closed 3 years ago.
Is there any easy way to copy one a column in a table to another table without changing the order ?
I am a beginner here. I would be much thankful to you if you could supply in depth answer.
I think this query can help you out
INSERT INTO second_table SELECT * FROM first_table WHERE id IN(1,2,3,4...n)

"Show databases" with condition

Is there a way to show a list of databases by condition?
Show databases WHERE table_name ='?' AND column_name = '?';
BEST BET:
Just itterate through all the databases, but if your trying to find a specific table why not just do this SHOW TABLES LIKE 'my_table_numer_%'; That will select a table with a begging part followed by a wild card text.

How would you fetch a mysql query with PDO (Or after PDO) in order to have this result? I mean the "titles of the columns" in the first position of the array and the values in the next positions? Can somebody helping me with an example?
[
["ColumnTitle","Column2Title"],
["RecordValue1","RecordValue2"],
["RecordValue1","RecordValue2"],
["RecordValue1","RecordValue2"],
["RecordValue1","RecordValue2"]
]
The mysql query returns:
ColumnTitle | Column2Title
----------------------------
RecordValue1 RecordValue2
RecordValue1 RecordValue2
RecordValue1 RecordValue2
RecordValue1 RecordValue2
I don't think this question was duplicate, this was a specific case.. :(
PDO doesn't offer such a format out of the box (because no developer would like it this way), but you can make it with minor tweaking
$data = $pdo->query('SELECT * FROM users')->fetchAll(PDO::FETCH_ASSOC);
array_unshift($data, array_keys($data));
But in your place I wouldn't add column names to the data array at all.

UPDATE/DELETE in mysql and get the list of affected row ids?
(3 answers)
Closed 9 years ago.
Title pretty much says it. I am using the deprecated mysql_ functions. I've got a query like:
UPDATE `table`
SET `row` = 'newtext'
WHERE `row` = 'oldtext'
Is there an easy way to get all effected row's primary key? Some glorious combination of mysql_insert_id and mysql_affected_rows? How can I do this without looping and doing each update one row at a time?
As a solution to your problem please refer the following sample code snippet
UPDATE `table` SET `row` = 'newtext' WHERE `row` = 'oldtext'
select id from table where row='oldtext'

CodeIgniter activerecord, retrieve last insert id?
(11 answers)
Closed 8 years ago.
This is PHP / CodeIgniter / MySQL
The only way I can think of is to do the insert ($this->db->insert(...)), and then immediatly after, run another query to find the record again.
I'm hoping there is something (which seems a bit more efficient to me) that returns the primary key (or something) of the newly added record.
For codeigniter
$this->db->insert_id()
Have a look at here http://ellislab.com/codeigniter/user_guide/database/helpers.html and the first function is $this->db->insert_id();
This also works with activerecord inserts.
or you can do
$last_insert_id = $this->db->call_function('insert_id');
