kevinshin created SPARK-42473: --------------------------------- Summary: An explicit cast will be needed when INSERT OVERWRITE SELECT UNION ALL Key: SPARK-42473 URL: https://issues.apache.org/jira/browse/SPARK-42473 Project: Spark Issue Type: Bug Components: Optimizer Affects Versions: 3.3.1 Environment: spark 3.3.1 Reporter: kevinshin
*when 'union all' and one select statement use* *Literal as column value , the other* *select statement has computed expression at the same column , then the whole statement will compile failed. A explicit cast will be needed.* for example: explain *INSERT* OVERWRITE *TABLE* test.spark33_decimal_orc *select* *null* *as* amt1, *cast*('256.99' *as* *decimal*(20,8)) *as* amt2 *union* *all* *select* *cast*('200.99' *as* *decimal*(20,8)){*}/{*}100 *as* amt1,*cast*('256.99' *as* *decimal*(20,8)) *as* amt2 *will got error :* org.apache.spark.*sql*.catalyst.expressions.Literal cannot be *cast* *to* org.apache.spark.*sql*.catalyst.expressions.AnsiCast The SQL will need to change to : explain *INSERT* OVERWRITE *TABLE* test.spark33_decimal_orc *select* *null* *as* amt1,*cast*('256.99' *as* *decimal*(20,8)) *as* amt2 *union* *all* *select* {*}cast{*}({*}cast{*}('200.99' *as* {*}decimal{*}(20,8)){*}/{*}100 *as* {*}decimal{*}(20,8)) *as* amt1,*cast*('256.99' *as* *decimal*(20,8)) *as* amt2 but this is not need in spark3.2.1 , is this a bug for spark3.3.1 ? -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
