Couldn't execute 'show fields from `association`'


Encountered this error while taking mysql dump

mysqldump: Couldn't execute 'show fields from `association`': Can't create/write to file '/tmp/#sql_647f_0.MYI' (Errcode: 2) (1)

Reason :
Can’t find tmp location to save it’s files

OS :  centos

Solution :

Step I
Open my.cnf (in this case it was at the location /etc/my.cnf).

Step II
Under [mysqld] add one more parameterad as :
tmpdir=/var/tmp

that solved the problem

Usually mysql uses /tmp or /var/tmp or /usr/tmp for storing it’s variable but if it doesn’t then try the above method.

How databasechangeloglock and databasechangelog table used by liquibase?

Liquibase takes care of executing the query on the database while maintaining the list of queries executed and also maintaining the locks over the tables simultaneously. The two tables that are used by the liquibase for this purpose are : Databasechangeloglock : This table have following columns ID | LOCKED| LOCKGRANTED | LOCKEDBY. This maintains the locks information granted to the user. The primary purpose of this table is to make sure that two machines don't attempt to modify the data at the same time. Databasechangelog : This table have following columns ID | AUTHOR | FILENAME | DATEEXECUTED | ORDEREXECUTED | EXECTYPE | MD5SUM | DESCRIPTION | COMMENTS | TAG | LIQUIBASE This table maintains the list of the statements that are executed on the database.

ReferenceError: dhtmlXGrid is not defined : Resolved

Reasons: 1. You are actually referring to a wrong location of the JS file.    - This is a very common mistake done and most of the time we are so damn sure that we don't even care about checking the path once. Even though you have copied it from your existing project where it is working, if you face this issue don't forget to check the path once, it won't harm you. 2. Check for relative path.    - So now you have copied it and paste it in your new file where you are going to use the dhtmlx component and when you open your file you get this error and it becomes frustrating knowing that same thing is wo
