### Describe the bug
Repro test case for `CometExpressionSuite`:
```scala
test("like with custom escape") {
val names = Seq("", "a_b", "d_e_f")
withTempDir { dir =>
val filename = "/tmp/percent.parquet"
names.toDF("a").write.mode(SaveMode.Overwrite).parquet(filename)
spark.read.parquet(filename).coalesce(1).createOrReplaceTempView("t")
val query = sql("select a from t where a like '%$_%' escape '$'")
checkSparkAnswerAndOperator(query)
}
}
```
Output:
```
