Reynold Xin created SPARK-12904: ----------------------------------- Summary: Strength reduction for integer/decimal comparisons Key: SPARK-12904 URL: https://issues.apache.org/jira/browse/SPARK-12904 Project: Spark Issue Type: Bug Components: Optimizer, SQL Reporter: Reynold Xin
We can do the following strength reduction for comparisons between an integral column and a decimal literal: 1. int_col > decimal_literal => int_col > floor(decimal_literal) 2. int_col >= decimal_literal => int_col > ceil(decimal_literal) 3. int_col < decimal_literal => int_col < floor(decimal_literal) 4. int_col <= decimal_literal => int_col < ceil(decimal_literal) This is useful more as soon as we start parsing floating point numeric literals as decimals rather than doubles (SPARK-12848). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
