-------------------------------------------

             Summary: Filtering by composite field name like `field name` doesn't work with pushDownPredicate = true
                 Key: SPARK-41990
                 URL: https://issues.apache.org/jira/browse/SPARK-41990
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.3.1, 3.3.0
            Reporter: Marina Krasilnikova


Suppose we have some table in postgresql with field `Last Name` The following code results in error

Dataset<Row> dataset = sparkSession.read()
.format("jdbc")
.option("url", myUrl)
.option("dbtable", "myTable")
.option("user", "myUser")
.option("password", "muPassword")
.load();

dataset.where("`Last Name`='Tessel'").show();    //error

 

 

Exception in thread "main" org.apache.spark.sql.catalyst.parser.ParseException: 
Syntax error at or near 'Name': extra input 'Name'(line 1, pos 5)

== SQL ==
Last Name
-----^^^

But if we set pushDownPredicate to false everything works fine.
