Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/). 

# TIMESTAMPTZ\$1CMP\$1DATE function
<a name="r_TIMESTAMPTZ_CMP_DATE"></a>

TIMESTAMPTZ\$1CMP\$1DATE compares the value of a timestamp and a date. If the timestamp and date values are identical, the function returns `0`. If the timestamp is greater chronologically, the function returns `1`. If the date is greater, the function returns `–1`.

## Syntax
<a name="r_TIMESTAMPTZ_CMP_DATE-syntax"></a>

```
TIMESTAMPTZ_CMP_DATE(timestamptz, date)
```

## Arguments
<a name="r_TIMESTAMPTZ_CMP_DATE-arguments"></a>

 *timestamptz*   
A column of data type `TIMESTAMPTZ` or an expression that implicitly evaluates to a `TIMESTAMPTZ` type.

 *date*   
A column of data type `DATE` or an expression that implicitly evaluates to a `DATE` type.

## Return type
<a name="r_TIMESTAMPTZ_CMP_DATE-return-type"></a>

INTEGER

## Examples

The following example compares LISTTIME as a timestamp with time zone to the date `2008-06-18`. Listings made after this date return `1`; listings made before this date return `-1`. 

```
select listid, CAST(listtime as timestamptz) as tstz,
timestamp_cmp_date(tstz, '2008-06-18')
from listing
order by 1, 2, 3
limit 10;
