AppVersionMapper

Info

MyBatis mapper interface for application version CRUD and update-count tracking.

Overview

AppVersionMapper provides data access for the app_version table, supporting lookups by app name, upsert, delete, and atomic update-count increments.

Methods

Method	Description	Returns
selectByAppName(appName)	Query version by application name	AppVersion or null
selectAll()	Query all version records	List<AppVersion>
insert(appVersion)	Insert a new version record	Affected rows
updateByAppName(appVersion)	Update version fields by app name	Affected rows
incrementUpdateCountByAppNameAndVersion(appName, version)	Atomically increment update_count for a specific app+version	Affected rows

Tips

incrementUpdateCountByAppNameAndVersion matches on both appName and version to ensure the counter only increments for the correct version.
