HI all,

I had above issue on connect to mySQL database through SQLContext. If the mySQL table's column name contains special characters like #[ ] %,  it throw exception : "You have an error in your SQL syntax".

Below is coding:

Class.forName("com.mysql.jdbc.Driver").newInstance()

val url = "jdbc:mysql://localhost:3306/sakila?user=root&password=xxx"
val driver = "com.mysql.jdbc.Driver"

val sqlContext = new SQLContext(sc)

val output = { sqlContext.load("jdbc", Map 
				(
					"url" -> url,
					"driver" -> driver,
					"dbtable" -> "(SELECT `ID`, `NAME%` FROM `agent`) AS tableA "
				)
			)
}

Hope dataframes for sqlContext can support for special characters very soon as this become a stopper  now.

Thanks
