URL: https://github.com/apache/doris-website/pull/3935
## Problem
The **Simple CTE** example in the Chinese `query-data/cte.md` used
full-width commas (`，` U+FF0C) **inside the SQL code block**:
```sql
WITH
cte1 AS (SELECT a，b FROM table1)，
cte2 AS (SELECT c，d FROM table2)
SELECT b，d FROM cte1 JOIN cte2
WHERE cte1.a = cte2.c;
```
Pasted as-is the statement fails to parse (`errCode = 2 ... we meet an error
when parsing`). The English counterpart and the **Nested CTE** block on the
same page already use half-width commas — only this one block was affected.
## Fix
Replace the 4 full-width commas with half-width `,` in the simple-example
SQL, making the ZH snippet identical to the canonical EN one. Chinese **prose**
commas are left untouched.
## Versions
- [ ] dev — N/A (ZH already rewritten, no longer contains this example)
- [ ] 4.x — N/A (same as dev)
- [x] 3.x
- [x] 2.1
## Languages
- [x] Chinese (only the ZH source carried the typo)
- [ ] English — N/A (already correct)
- [ ] Japanese — not touched
## Verification
The snippet is an illustrative example over undefined `table1`/`table2` (no
setup, no expected-output table), so it has no cluster oracle to run
end-to-end; correctness is established against the already-correct EN
counterpart and the half-width Nested-CTE block on the same page. The change is
a pure full-width→half-width comma typo fix confined to the SQL fence.
