Date range query on Timestamp field in HQL

January 18, 2023January 18, 2023 by manish

Suppose we want to make query between two dates in a timestamp field for example We have a table colors to store different colors

create table colors(
color_id bigint(10)NOT NULL AUTO_INCREMENT,
color varchar(50),
add_date timestamp DEFAULT 0,
status varchar(20),
primary Key(color_id));

create table colors(

color_id bigint(10)NOT NULL AUTO_INCREMENT,

color varchar(50),

add_date timestamp DEFAULT 0,

status varchar(20),

primary Key(color_id));

Pojo class for color table is

public class Color  implements java.io.Serializable {
     private Long colorId;
     private String color;
     private Timestamp addDate;
     private String status;
//getter setter and constructor

public class Color implements java.io.Serializable {

private Long colorId;

private String color;

private Timestamp addDate;

private String status;

//getter setter and constructor

Above class shows that addDate is timestamp field and we want to query it as date for that we have casted timestamp field … Read more
