             Summary: org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils.saveTable  the case senstivity issue
                 Key: SPARK-18123
                 URL: https://issues.apache.org/jira/browse/SPARK-18123
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.1
            Reporter: Paul Wu


I have issue with the saveTable method in Spark 2.0/2.0.1. I tried to save a dataset to Oracle database, but the fields must be uppercase to succeed. This is not a expect behavior: If only the table names were quoted, this utility should concern the case sensitivity.  The code below throws the exception: Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "DATETIME_gmt": invalid identifier. 

String detailSQL ="select CAST('2016-09-25 17:00:00' AS TIMESTAMP) DATETIME_gmt, '1' NODEB";
        hc.sql("set spark.sql.caseSensitive=false");
        Dataset<Row> ds = hc.sql(detailSQL);
        ds.show();
        org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils.saveTable(ds, url, detailTable, p);
