Store Enums in DB
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I was asked to make a a column called Type a varchar2(1)which has values partial or all
That what i made in Model.Java
@Column(name="TYPE")
@Enumerated(EnumType.STRING)
public TypeEnum getType() {
return type;
}
public void setType(TypeEnum type) {
this.type = type;
}
And this is my TypeEnum.java
public enum TypeEnum {
ALL(0, "all"),
PARTIAL(1, "partial");
private int code;
private String value;
private TypeEnum(int code, String value) {
this.code = code;
this.value = value;
}
public String getValue() {
return value;
}
public int getCode() {
return code;
}
public static TypeEnum getTypeEnum(String value){
TypeEnum types = values();
for(int i=0; i<types.length; i++){
TypeEnum type = types[i];
if(value.equals(type.getValue()))
return type;
}
return null;
}
}
So how to store the TypeEnum in DB to achieve the varchar2(1)

You could use a Converter to map your enums to varchar(1) yourself. Something like:
@Column("TYPE") @Convert(TypeEnumToString.class) TypeEnum type;
with the converter class implemented something like:
public class TypeEnumToString implements AttributeConverter<TypeEnum, String> {
@Override
public TypeEnum convertToEntityAttribute(String value) {
// return conversion;
}
@Override
public String convertToDatabaseColumn(TypeEnum value) {
// return conversion;
}
}

You can achieve this by implementing AttributeConverter<TypeEnum, String>
@Converter
public class TypeEnumConverter implements AttributeConverter<TypeEnum, String> {
@Override
public String convertToDatabaseColumn(TypeEnum attribute) {
return String.valueOf(attribute.getCode());
}
@Override
public TypeEnum convertToEntityAttribute(String dbData) {
return getTypeEnumFromCode(parseInt(dbData));
}
}
getTypeEnumFromCode can be implemented similar to your getTypeEnum method.
Then, define it like
@Column("TYPE")
@Convert(TypeEnumToString.class)
TypeEnum type;
p.s.I just used code from your enum but it can be any other logic too.

getTypeEnumFromCode can be implemented similar to your getTypeEnum method.
Then, define it like
@Column("TYPE")
@Convert(TypeEnumToString.class)
TypeEnum type;
p.s.I just used code from your enum but it can be any other logic too.
