YuanGuanhu created SPARK-37643: ---------------------------------- Summary: when charVarcharAsString is true, char datatype partition table query incorrect Key: SPARK-37643 URL: https://issues.apache.org/jira/browse/SPARK-37643 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 3.2.0, 3.1.2 Environment: spark 3.2.0 Reporter: YuanGuanhu
This ticket aim at fixing the bug that does not apply right-padding for char types partition column when charVarcharAsString is true and partition data length is lower than defined length. For example, a query below returns nothing in master, but a correct result is `abc`. {code:java} scala> sql("set spark.sql.legacy.charVarcharAsString=true") scala> sql("CREATE TABLE tb01(i string, c char(5)) USING parquet partitioned by (c)") scala> sql("INSERT INTO tb01 values(1, 'abc')") scala> sql("select * from tb01 where c = 'abc'").show +---+ | c| +---+ +---+{code} This is because `ApplyCharTypePadding` rpad the expr to charLength. We should handle this consider conf spark.sql.legacy.charVarcharAsString value. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
