-----------------------------------
Target Version/s: 2.4.0 (was: 2.3.0)

> Key: SPARK-20319
> URL: https://issues.apache.org/jira/browse/SPARK-20319
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0, 2.1.0

> The issue was caused by [SPARK-16387|https://issues.apache.org/jira/browse/SPARK-16387] where reserved SQL words are honored by wrapping quotes on column names.
> In our test we found that when quotes are explicitly wrapped in column names then Oracle JDBC driver is throwing :

> at oracle.jdbc.driver.OraclePreparedStatement.executeBatch(OraclePreparedStatement.java:12296)
> at oracle.jdbc.driver.OracleStatementWrapper.executeBatch(OracleStatementWrapper.java:246)
> at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.savePartition(JdbcUtils.scala:597)
> and Cassandra JDBC driver is throwing :
> 17/04/12 19:03:48 ERROR executor.Executor: Exception in task 0.0 in stage 5.0 (TID 6)
> java.sql.SQLSyntaxErrorException: [FMWGEN][Cassandra JDBC Driver][Cassandra]syntax error or access rule violation: base table or view not found:
