Question : mySQL problem

Hi Experts,

I am having a tough time trying to restore some tables in a mySQL DB using MyPhpAdmin.

It appears that the SQL generated by the export or backup  abc.sql file insists that tables be created with foreign key constraints and/or references to tables that don't exist because the are created after the one that throws the error.  The .sql file sequence seems to be out of order given the FK constraints (i.e. contact table is created later in the script).  How do the experts handle it when the .sql file to be imported seems to be sequentially wrong? (it's 6000 lines)

Thanks, HNM

Here is the error message and an example of a table that causes the situation.

MySQL said:  
#1005 - Can't create table './xyz123/civicrm_acl_cache.frm' (errno: 150)

SQL query:

CREATE TABLE `civicrm_acl_cache` (

`id` int( 10 ) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Unique table ID',
`contact_id` int( 10 ) unsigned default NULL COMMENT 'Foreign Key to Contact',
`acl_id` int( 10 ) unsigned NOT NULL COMMENT 'Foreign Key to ACL',
`modified_date` date default NULL COMMENT 'When was this cache entry last modified',
PRIMARY KEY ( `id` ) ,
KEY `index_acl_id` ( `acl_id` ) ,
KEY `FK_civicrm_acl_cache_contact_id` ( `contact_id` ) ,
CONSTRAINT `FK_civicrm_acl_cache_acl_id` FOREIGN KEY ( `acl_id` ) REFERENCES `civicrm_acl` ( `id` ) ON DELETE CASCADE ,
CONSTRAINT `FK_civicrm_acl_cache_contact_id` FOREIGN KEY ( `contact_id` ) REFERENCES `civicrm_contact` ( `id` ) ON DELETE CASCADE ) ENGINE = InnoDB DEFAULT CHARSET = utf8 COLLATE = utf8_unicode_ci

Answer : mySQL problem

Hi HNM,

  Did you try adding it to the script, ie at line 1 of your import script to be sure that setting was applied to the same running connection?
