You still have the 1MB data cap for queries.

Just created a table and created a data type from the table and this is the XSD that it generated.

Seems like it used LONGTEXT.

Now I am trying to create entity and map in datastore but getting this error :

The data source schema does not match the type mappings: Schema-validation: wrong column type encountered in column [JSON_DATA] in table [`LKG_TEST`];
found [longtext (Types#LONGVARCHAR)], but expecting [text (Types#VARCHAR)] (APNX-2-4056-000)

Via queryRecord it is limited to 4000 (before 25.1)

You need to use queryEntity.

HI Mathieu,
Thanks for the quick response.
I have updated the annotation on XSD file. Now I have observed while querying the data using query record I see the field is not calling complete JSON data it is able to pull only 4497 characters.

I have checked the datatype of that particular column in record which is set as follows.

Could you please suggest how to pull all the available JSON data into queryrecord instead of breaking.

Yes.

does this will help to get the data more than 4000 characters ?

You need to manually update the XSD to use @Column(columnDefinition = "TEXT") for the desired column.
