Added odbc_default_field_size Option for ODBC Source Value Size扩大

Published: November 25, 2025

Added the odbc_default_field_size option, which allows you to extend the maximum size of the value loaded from an ODBC source (by default, it is 1024).

Added the odbc_default_field_size setting to increase the maximum size of values loaded from ODBC sources (default is 1024).

Why it matters

This feature addresses the limitation of the default maximum field size when importing data from ODBC sources, allowing users to load larger values without truncation.

How to use it

Set the odbc_default_field_size parameter to the desired maximum size before loading data from an ODBC source. For example:

SET odbc_default_field_size = 4096;
SELECT * FROM odbc(...);
