Eugene Golovan created SPARK-26077:
--------------------------------------
Summary: Reserved SQL words are not escaped by JDBC writer for
table name
Key: SPARK-26077
URL: https://issues.apache.org/jira/browse/SPARK-26077
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.3.2
Reporter: Eugene Golovan
This bug is similar to SPARK-16387 but this time table name is not escaped.
How to reproduce:
1/ Start spark shell with mysql connector
spark-shell --jars ./mysql-connector-java-8.0.13.jar
2/ Execute next code
import spark.implicits._
(spark
.createDataset(Seq("a","b","c"))
.toDF("order")
.write
.format("jdbc")
.option("url", s"jdbc:mysql://root@localhost:3306/test")
.option("driver", "com.mysql.cj.jdbc.Driver")
.option("dbtable", "condition")
.save)
, where condition - is reserved word.
Error message:
java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check
the manual that corresponds to your MySQL server version for the right syntax
to use near 'condition (`order` TEXT )' at line 1
