hi,
can we write a update query using sqlcontext?
sqlContext.sql("update act1 set loc = round(loc,4)")
what is wrong in this? I get the following error.
Py4JJavaError: An error occurred while calling o20.sql.
: java.lang.RuntimeException: [1.1] failure: ``with'' expected but
identifier update found
update act1 set loc = round(loc,4)
