I am inserting a record successfully in the database table. The primary key (member_id) is set to auto_increment. I want when I insert a member record and a new member_id is created, to retrieve that same record id immediately from the same query. Is that possible?
Regards,
$this->db->insert_id() will get the latest id from the database.
See: http://ellislab.com/codeigniter/user-guide/database/helpers.html
$this->db->insert('...');
$member_id = mysql_insert_id();
This would work also, its the standart PHP function.

Hi any one can help me on this issue which i have problem insert a dynamic value which is from previous database table value to pass to another table in Katalon.
Please find my information below:-
This screenshot is ab.dbo.DOCUMENT table which DOCUMENT_ID is auto populate with value
which mean it will appear random number by itself.
Another screenshot is bc.dbo.DOCUMENT_IC table which i need to manually key in DOCUMENT_ID in
the value base on on what it is given from ab.dbo.DOCUMENT table DOCUMENT_ID.
Attached of a screenshot for bc.dbo.DOCUMENT_IC
In Katalon i am using a keyword to connect my database, insert query and close
connection. I am aware of this step and able to connect to database with katalon. But i
am not very sure how to pass a dynamic value from ab.dbo.DOCUMENT table DOCUMENT_ID which
it can randomly appear a number value to bc.dbo.DOCUMENT_IC table DOCUMENT_ID which i need to
manually key in a value base on the value given.
Below is my Katalon script:-
Hopefully someone can help me on this
Thank you.
If I have a table with an auto incrementing ID in one table and I need that value elsewhere I would typically write sql like this :
insert into firsttable (Document_Type) values ('PDF');
insert into secondtable (Document_ID, App_ref_Num) values (##Identity, 'somenumber')
In the databases I have worked with ##Identity will give you the integer or id of the last inserted row. If you can't run multiple statements most connection libraries will have something like a $conn->insert_id that will do the same thing as running select ##identity.
Is there any simple way to move data from table to table using the id? I want to get all the info inside the first table using the id, insert it to another table, and then delete it from current one using Laravel.
Assuming both tables have the same schema you can do:
TableB::create(TableA::find($id));
I have a table that is fk from another table. when I try to delete the record, I get an error because it is not possible to delete a record that is used as fk in another table. Has anyone ever used laravel's validator to validate this situation?
How to create unique id in cassandra column families( like auto-increment id in mysql database ) ?
For unique IDs in Cassandra, you'll want to use UUIDs, which are probabilistically (nearly) guaranteed to be unique. There are a few built-in functions in CQL to help with UUIDs.
You asked for simple query to create table with uuid, so there you are:
create:
CREATE TABLE event (uuid uuid, name varchar);
insert:
INSERT INTO event(uuid, name) values(uuid(), 'john');
select:
SELECT * FROM event LIMIT 1;
to select on name column you must add new index:
CREATE index idx_event_name ON event(name);
and now you can select with where:
SELECT * FROM event WHERE name = 'john';
If you really need integer autoincrement IDs I've written a simple python module that does that after going through stackoverflow and not seeing anything decent that does that specific function. If you don't care about the ID being an integer you're better off using something like UUID which is probably safer and more elegant.

I'm trying to update some existing code that is supposed to write data to a variety of Databases (SQL, Access, Oracle) via ODBC, but I'm having a few problems with Oracle and am looking for any suggestions.
I've set my Oracle database up using a Trigger (basic tutorial online, which I'd like to support).
CREATE TABLE TABLE1 (
RECORDID NUMBER NOT NULL PRIMARY KEY,
ID VARCHAR(40) NULL,
COUNT NUMBER NULL
);
GO
CREATE SEQUENCE TABLE1_SEQ
GO
CREATE or REPLACE TRIGGER TABLE1_TRG
BEFORE INSERT ON TABLE1
FOR EACH ROW
WHEN (new.RECORDID IS NULL)
BEGIN
SELECT TABLE1_SEQ.nextval
INTO :new.RECORDID
FROM dual;
end;
GO
I then populate a DataTable using a SELECT * FROM TABLE1. The first problem is that this DataTable doesn't know that the RecordId column is auto-generated. If I have data in my table then I can't alter it because I get a error
Cannot change AutoIncrement of a DataColumn with type 'Double' once it
has data.
If I continue, ignoring this, then I quickly get stuck. If I create a new DataRow and try to insert it, I can't set RecordID to DBNull.Value because it complains that the column has to be non-null (NoNullAllowedException). I can't however generate a value myself, because I don't know what value I should be using really, and don't want to screw up the trigger by using the next available value.
Any suggestions on how I should insert data without ODBC complaining?
It does not appear that your first problem is with an Oracle database. There is no such thing as an "Autoincrement" column in Oracle. Are you sure that message is coming from an Oracle database?
With Oracle, you should be able to provide any dummy value on insert for the primary key, and the trigger will overwrite it.
There is also nothing in your provided description that would prevent you from updating this value in Oracle (since your trigger is on insert only) unless you have foreign key references to the key.
