Davies Liu created SPARK-19415: ---------------------------------- Summary: Improve the implicit type conversion between numeric type and string to avoid precesion loss Key: SPARK-19415 URL: https://issues.apache.org/jira/browse/SPARK-19415 Project: Spark Issue Type: Improvement Components: SQL Reporter: Davies Liu
Currently, Spark SQL will convert both numeric type and string into DoubleType, if the two children of a expression does not match (for example, comparing a LongType again StringType), this will cause precision loss in some cases. Some database does better job one this (for example, SQL Server [1]), we should follow that.
