I think SparkSQL does not have a consistent behavior. See example below: SparkSQL 3.x Thrift Server JDBC ``` CREATE TEMPORARY TABLE t1 (t1_id INT,t1_name String); select t1_id, cast(t1_id as decimal(10, 0)), t1_id + cast(t1_id as decimal(10, 0)) from t1; ``` Result: +-----+-----+-------------------------------------------------------------------+ | t1_id | t1_id | (CAST(t1_id AS DECIMAL(10,0)) + CAST(t1_id AS DECIMAL(10,0))) | +-----+-----+-------------------------------------------------------------------+ +-----+-----+-------------------------------------------------------------------+ -- This is an automated message from the Apache Git Service.
