I am trying to insert an auto_increment value into multiple tables but its seems to lose its value after the the second insert statement and my code is as follows can any1 please help. The auto_increment value that i want to use is the one from the client table and it will insert in the CONTACTS table but it will not in the JOBSHEET and KNOWLEDGE table. last_insert_id( ) has not worked because i have auto increment fields in all the tables pliz pliz help
mysql_query("IN SERT INTO CLIENT VALUES(
NULL, '$companyname', '$contactname', '$siteaddress', '$phonenumber', NULL, '$website', '$code', '$postaladdress ')") or die (mysql_error()) ;
mysql_query('SE T @clientID = last_insert_id( )') or die (mysql_error()) ;
mysql_query("IN SERT INTO CONTACTS VALUES( NULL, '@clientID' )") or die (mysql_error()) ;
mysql_query("IN SERT INTO JOBSHEET VALUES( NULL, '@clientID')") or die (mysql_error()) ;
mysql_query("IN SERT INTO KNOWLEDGE VALUES( NULL, '@clientID', '$categoryID', '$staffID', '$knowledge')") or die (mysql_error()) ;
1 4111 MySQL doc: The currently executing statement does not affect the value of LAST_INSERT_ID( ). Suppose that you generate an AUTO_INCREMENT value with one statement, and then refer to LAST_INSERT_ID( ) in a multiple-row INSERT statement that inserts rows into a table with its own AUTO_INCREMENT column. The value of LAST_INSERT_ID( ) will remain stable in the second statement; its value for the second and later rows is not affected by the earlier row insertions. (However, if you mix references to LAST_INSERT_ID( ) and LAST_INSERT_ID( expr), the effect is undefined.)
Sample from M ySQL docs: If you want store the last id for use in multiple insert statements: - create table person (
-
id bigint not null primary key auto_increment,
-
name char(100) not null
-
);
-
insert into person set name = 'Joe';
-
select @id:=id as id from class where id = last_insert_id();
-
insert into some_other_table set person_id = @class_id;
-
insert into yet_another_table set person_id = @class_id;

Hello,
I've just installed perl DBI v1.38 which according to the
documentation supports the method last_insert_id(). For some reason
the return value I get is undef.
Here is my source code :

hi,
how to implement mysql's last_insert_id() ?
i know that seqences and oids are great.
the one thing i miss is that they are not session specific.
i mean selecting last_value from seqence can give me a value which was
inserted by a different user.

Hello,
I am trying to get the value of the Auto-Incremented key that was assigned
using LAST_INSERT_ID(). However, when I execute the following PHP statements
after the insert I only get: "value of entryID: Resource id #7" after EVERY
insert (it never changes).
What am I doing wrong?
Thanks very much!

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

This is as boiled down as I can make it.
