Long Date Conversion

Overview

The Long Date Conversion operator performs long integer and date conversion.

Input and Output

Input: fields to be converted
Output: new fields

Parameter Description

**Table 1** Operator parameter description
Parameter	Description	Type	Mandatory	Default Value
convert type	Types of long integer and date conversion: long to date: converts long integers to date. long to time: converts long integers to time. long to timestamp: converts long integers to timestamp. date to long: converts date to long integers. time to long: converts time to long integers. timestamp to long: converts timestamp to long integers.	enum	Yes	long to date
input field name	Name of input fields to be converted. Set this parameter to the names of fields generated in the previous conversion step.	string	Yes	None
output field name	Names of output fields.	string	Yes	None
field unit	Unit of a long integer field. According to convert type, the value is an input field or generated field. The options are second and millisecond.	enum	Yes	second
output field type	Output field type. The options are BIGINT, DATE, TIME, and TIMESTAMP.	enum	Yes	BIGINT
date format	Time field format, for example, yyyyMMdd HH:mm:ss.	string	No	None

Data Processing Rule

If the original data includes null values, no conversion is performed.
If the number of input field columns is greater than the number of field columns actually included in the original data, all data becomes dirty data.
If a type conversion error occurs, the current data is saved as dirty data.

Example

Use the CSV File Input operator to generate fields A and B.

The following figure shows the source file.

Configure the Long Date Conversion operator to generate four new fields C, D, E, and F. Their types are DATE, TIME, TIMESTAMP, and BIGINT, respectively.
