Hi,  
I am using logstash to insert data from sql to index.  
I am using a date column **compare\_date** to compare for sql\_last\_value field.  
When I am running, logstash automatically reduce 1 day from **compare\_date**.  
Suppose my **compare\_date** is 2021-10-01, it automatically change it to 2021-09-30.  
Here is my query:

```auto
SELECT * FROM(
select month,year, TO_DATE('01-'||LPAD(month,2,'0')||'-'||year,'dd-MM-YYYY') as compare_date
FROM my_table GROUP BY year,month ORDER BY year, month Asc
)
WHERE compare_date > :sql_last_value AND compare_date < NOW()

```

if month is 10 and year is 2021 than it change compare\_date to 2021-09-30

I wonder if you are hitting [this](https://github.com/logstash-plugins/logstash-input-jdbc/issues/293) issue.
