MaxGekk opened a new pull request #27323: [SPARK-30606][SQL] Fix the `like` function with 2 parameters URL: https://github.com/apache/spark/pull/27323 ### What changes were proposed in this pull request? In the PR, I propose to add additional constructor in the `Like` expression. The constructor can be used on applying the `like` function with 2 parameters. ### Why are the changes needed? `FunctionRegistry` cannot find a constructor if the `like` function is applied to 2 parameters. ### Does this PR introduce any user-facing change? Yes, before: ```sql spark-sql> SELECT like('Spark', '_park'); Invalid arguments for function like; line 1 pos 7 org.apache.spark.sql.AnalysisException: Invalid arguments for function like; line 1 pos 7 at org.apache.spark.sql.catalyst.analysis.FunctionRegistry$.$anonfun$expression$7(FunctionRegistry.scala:618) at scala.Option.getOrElse(Option.scala:189) at org.apache.spark.sql.catalyst.analysis.FunctionRegistry$.$anonfun$expression$4(FunctionRegistry.scala:602) at org.apache.spark.sql.catalyst.analysis.SimpleFunctionRegistry.lookupFunction(FunctionRegistry.scala:121) at org.apache.spark.sql.catalyst.catalog.SessionCatalog.lookupFunction(SessionCatalog.scala:1412) ``` After: ```sql spark-sql> SELECT like('Spark', '_park'); true ``` ### How was this patch tested? By running `check outputs of expression examples` from `SQLQuerySuite`.
