create a global jdbc connection in scala to run multiple queries
I am trying to create a code that basically creates a jdbc connection (only once) to the run a certain function n times. How would this be possible?
I have tried something like this:
class conn(name: String) {
DriverManager.registerDriver(new OracleDriver())
val conn =
DriverManager.getConnection("jdbc:oracle:thin:@rest_of_the_link",
"user", "pass")
var output : Int;
def spArray() : Int = {
var callableStatement: CallableStatement = conn.prepareCall("Statement_to_run;")
callableStatement.registerOutParameter(1,Types.INTEGER)
callableStatement.execute()
output = callableStatement.getObject(1).asInstanceOf[Int]
};
};
I tried the approach of doing everything within a function but I want to get rid of the handicap of 'creating connection' for each iteration I will perform later.
Thanks a lot!
