Question

Using ResultSet I can get ResultSetMetaData from which I can get size of the database column in characters (for example 15 for varchar(15)) using metaData.getColumnDisplaySize(index). Is it any way I can get this size using jOOQ?

With ResultSet I have problem with UDT and I am already using jOOQ for access to database (and it works well with UDT) so it would be perfect if yes

Answer 1

The meta information that you’re looking for is not provided by jOOQ 2.x APIs. Adding length, precision, and scale to the org.jooq.DataType API is planned for the upcoming release 3.0

This is registered as feature request #456

As a matter of fact, this is now implemented on github, and will be included in jOOQ 3.0. The API usage needed to achieve what you’re looking for will look like this (an example):

int length = record.getField(0).getDataType().length();

In essence, org.jooq.DataType will have these three methods:

int length();
int precision();
int scale();
