TRUNC (date) UDF

Description

The TRUNC (date) function returns date with the time portion of the day truncated to the unit specified by the format model fmt. (Oracle TRUNC(date) SQL Language Reference)

TRUNC(date [, fmt ])

Oracle TRUNC and Snowflake TRUNC function with date arguments have some functional differences.

TRUNC_UDF helper will be added to handle the following cases:

1. The format is not supported by Snowflake.

2. The format exists in Snowflake but works differently.

3. The tool cannot determine the datatype of the first argument.

4. The format is provided as a column or expression and not as a literal.

Please refer to EWI3083 and EWI3117 for examples of each case.

Custom UDF overloads

TRUNC_UDF(date)

It applies an explicit DATE cast to the input Timestamp.

Parameters

1. INPUT: The Timestamp with Time Zone (TIMESTAMP_LTZ) that needs to be truncated.

The default parameter for the UDF is TIMESTAMP_LTZ. It may need to be changed to TIMESTAMP_TZ or TIMESTAMP_NTZ to match the default TIMESTAMP used by the user.

UDF

CREATE OR REPLACE FUNCTION PUBLIC.TRUNC_UDF(INPUT TIMESTAMP_LTZ)
RETURNS DATE
IMMUTABLE
AS
$$
    INPUT::DATE
$$;

TRUNC_UDF(date, fmt)

Manually creates a new date using DATE_FROM_PARTS() function, depending on the format category used.

Parameters

1. DATE_TO_TRUNC: The Timestamp with Time Zone (TIMESTAMP_LTZ) that needs to be truncated.

2. DATE_FMT: The date format as a VARCHAR. Same formats that are supported in Oracle.

The default parameter for the UDF is TIMESTAMP_LTZ. It may need to be changed to TIMESTAMP_TZ or TIMESTAMP_NTZ to match the default TIMESTAMP used by the user.

Known Issues

1. Oracle DATE contains TIMESTAMP

Take into consideration that Oracle DATE contains an empty TIMESTAMP (00:00:00.000), while Snowflake DATE does not. SnowConvert allows transforming DATE to TIMESTAMP with the SysdateAsCurrentTimestamp flag.

Related EWIs

1. MSCEWI3083: Unhandled arguments for the TRUNC function.

2. MSCEWI3117: Day format works differently between Oracle and Snowflake.
