SQL 语句优化：获取维护计划数据

Yes, the SQL statement you provided is correct. It selects various columns from the tables "cm_maintenance_plan" and "customer_info" and uses an INNER JOIN to join the two tables based on the "customer_id" column. The query also includes a placeholder for a custom SQL segment using the variable "ew.customSqlSegment". Finally, the query includes a LIMIT clause to limit the number of rows returned based on the current page and size parameters. This SQL statement can be written in a mapper.xml file.
