jOOQ does not use custom data binding


jOOQ does not use custom data binding

I wish this help you I am trying to write a custom data type binding for PGInterval and Duration to use jOOQ together with TimescaleDB. Sadly jOOQ does not use it when generating functions for the database routines. , You are confusing the two configuration flags:
code :
<expression>.*interval.*</expression>
<types>.*</types>
<types>.*interval.*</types>
<expression>.*</expression>

this one helps. Use a SQL query to produce the list of columns from your database to feed into that regular expression. Something like:
code :
SELECT string_agg(n.nspname || '\.' || c.relname || '\.' || a.attname, '|')
FROM pg_namespace n
JOIN pg_class c ON c.relnamespace = n.oid
JOIN pg_attribute a ON a.attrelid = c.oid
JOIN pg_type t ON a.atttypid = t.oid
WHERE t.typname = 'json'

it fixes the issue If by "I'm using Java", you mean using programmatic code generator configuration using Java:
There's a manual section about programmatic code generator configuration here:
code :
DataType<MyJsonType> jsonType = 
    SQLDataType.VARCHAR.asConvertedDataType(new MyJsonBinding());
Field<MyJsonType> jsonField = field(name("my_table", "my_column"), jsonType);

like below fixes the issue Your Binding implementation is the wrong place to look for a solution to this problem. You don't really want to change the binding of your column to somehow magically know of this json_set function, which does an incremental update of the json data rather than a full replacement. When you use UpdatableRecord.store() (which you seem to be using), the expectation is for any Record.field(x) to reflect the content of the database row exactly, not a delta. Of course, you could implement something similar in the sql() method of your binding, but it would be very difficult to get right and the binding would not be applicable to all use-cases.
Hence, in order to do what you want to achieve, simply write an explicit UPDATE statement with jOOQ, enhancing the jOOQ API using plain SQL templating.
code :
// Assuming this static import
import static org.jooq.impl.DSL.*;

public static Field<Map<String, String>> jsonSet(
    Field<Map<String, String>> field,
    String key,
    String value
) {
    return field("json_set({0}, {1}, {2})", field.getDataType(), field, inline(key), val(value));
}
using(configuration)
    .update(WIDGET)
    .set(WIDGET.JM_DATA, jsonSet(WIDGET.JM_DATA, "$.\"key1\"", "updated_value1"))
    .where(WIDGET.WIDGET_ID.eq(1))
    .execute();

fixed the issue. Will look into that further In many JDBC drivers, you cannot use PreparedStatement.setObject(index, null) because the JDBC driver needs to know what type of NULL it should serialise over the wire to the server. I don't know what crate.io expects here (it's not an officially supported database in jOOQ), but the usual options are:

wish help you to fix your issue jOOQ 3.12 introduced the new org.jooq.JSON type, which applies automatically to your generated code. Before, the type could not be mapped, and was thus generated as SQLDataType.OTHER, which corresponds to java.lang.Object
Your binding was working before, because it was probably a Binding. You will have to change this binding to Binding to fix this.
