+The table creation statements will be generated based on the upstream data

+ ${rowtype_primary_key},
+ ${rowtype_fields}
+) ENGINE = MergeTree()
+ORDER BY (${rowtype_primary_key})
+PRIMARY KEY (${rowtype_primary_key})
+SETTINGS
+ index_granularity = 8192;
+```
+
+If custom fields are added to the template, for example, adding an `id` field:
+
+```sql
+CREATE TABLE IF NOT EXISTS `${database}`.`${table_name}` (
