-------------------------------------

             Summary: Use prepared statement instead of Statement in 
JdbcRecordReader class
                 Key: DRILL-6215
                 URL: https://issues.apache.org/jira/browse/DRILL-6215
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - JDBC
    Affects Versions: 1.12.0
            Reporter: Khurram Faraaz


Use prepared statement instead of Statement in JdbcRecordReader class, which is 
more efficient and less vulnerable to SQL injection attacks.

Apache Drill 1.13.0-SNAPSHOT, commit : 9073aed67d89e8b2188870d6c812706085c9c41b

Findbugs reports the below bug and suggests that we use prepared statement 
instead of Statement.

In class org.apache.drill.exec.store.jdbc.JdbcRecordReader
In method 
org.apache.drill.exec.store.jdbc.JdbcRecordReader.setup(OperatorContext, 
OutputMutator)
At JdbcRecordReader.java:[line 170]
org.apache.drill.exec.store.jdbc.JdbcRecordReader.setup(OperatorContext, 
OutputMutator) passes a nonconstant String to an execute method on an SQL 
statement

The method invokes the execute method on an SQL statement with a String that 
seems to be dynamically generated. 
Consider using a prepared statement instead. 
It is more efficient and less vulnerable to SQL injection attacks.

To run with findbugs:
mvn clean install -Pfindbugs -DskipTests

Findbugs will wirite the output to finbugsXml.html in the target directory of 
each module. 
For example the java-exec module report is located at: 
./exec/java-exec/target/findbugs/findbugsXml.html
Use 
find . -name "findbugsXml.html"
to locate the files.
