Table autoincrement property gets removed

[11年前 に Samita Bhujbal によって更新されました。]

I am using Liferay 6.0.6. I am working on custom module for membership registration. I am using service builder for dealing with tables.. There are 20 tables involved on this module. I have made each table primary key autoincrement from SQLYog so that when data gets added in table it increments primary key automatically.
But sometimes this autoincrement property gets removed automatically. Also we have applied unique index to one table for one column. That also gets deleted automatically sometimes.
What Can be the reason? Is it due to I have set cron job on server which takes daily backup of database ? Or it may due to uploading the updated build on server??

Each time you deploy with change in the service.xml Liferay will check for any changes and update the tables .

I have made each table primary key autoincrement from SQLYog

I don't understand why you did this and not do it the way liferay does it? (CounterService)

I did it. But CounterLocalServiceUtil generates duplicate primaryid sometimes. Hence I changed to this.

Have you implemented like this :

CounterLocalServceUtil.increment(yourEntity.class.getName());

yes I did this only. But sometimes it was creating duplicate primaryID. So I removed this from code and set primaryId column as autoincremented in Mysql.

Hi Samita,

Samita Bhujbal:

Can you repeat this behavior and which situation you are getting this?

Hi Samita,

Do avoid these kind of issues use

CounterLocalServceUtil.increment();

Without giving entity name as parameter, this will always return you new and unique key for sure..

hope this helps you.

Thanks,
Jaynil

But when we want to add entries for specific entity then giving entity name is necessary.
