limit after groupby on sql query
In SQL, you can use the LIMIT clause after a GROUP BY statement to limit the number of rows returned from the result set. However, the specific syntax may vary depending on the SQL database management system (DBMS) you are using.

Here are some examples of how you can use the LIMIT clause after GROUP BY in different SQL DBMS:

1. MySQL:
```sql
SELECT column1, column2, COUNT(*)
FROM table_name
GROUP BY column1, column2
LIMIT 10; -- limit to 10 rows
```

2. PostgreSQL:
```sql
SELECT column1, column2, COUNT(*)
FROM table_name
GROUP BY column1, column2
LIMIT 10; -- limit to 10 rows
```

3. SQL Server:
```
SELECT TOP 10 column1, column2, COUNT(*)
FROM table_name
GROUP BY column1, column2;
```

Note that the syntax for limiting the result set may vary depending on the DBMS you are using. In some cases, you may also need to use other keywords such as FETCH FIRST or ROWNUM depending on the DBMS. It's best to consult the documentation of your specific DBMS for the correct syntax for limiting the result set after a GROUP BY statement.
