I want to pass parameters to the sql query for #databricks/sql module but I am unable to figure out a way. The node.js package has this issue listed if anybody knows a work around?
Parameterizing the query for prevention of sql injection of application.

I'm working with JPA. How could my application be SQL injection safe if I'm using a native sql query (not entity query)? I need to build the native sql query with the data submitted by a user from a html form.
If I use parameters in the native sql I can avoid SQL injection attacks, but my problem is that I can't be sure how many data fields are being submitted by the user.
You should use positional parameters binding:
String queryString = "select * from EMP e where e.name = ?1";
Query query = em.createNativeQuery(queryString, Employee.class);
query.setParameter(1, "Mickey");
Please note that you should not use named parameters binding (:empName) in your query as JPA Spec says
Only positional parameter binding may be portably used for native queries.
This should secure you from SQL Injection attacks.
Hello for demonstration purposes I trimmed out my actual sql query.
I have a SQL query
SELECT *
FROM dbdev.training.courses
where dbdev is my DEV database table name. When I migrate to TEST env, I want my query to dynamically change to
SELECT *
FROM dbtest.training.courses
I tried using input parameters like {env: p('db_name')} and using in the query as
SELECT * FROM :env.training.courses
or
SELECT * FROM (:env).training.courses
but none of them worked. I don't want my SQL query in properties file.
Can you please suggest a way to write my SQL query dynamically based on environment?
The only alternative way is to deploy separate jars for different environments with different code.
You can set the value of the property to a variable and then use the variable with string interpolation.
Warning: creating dynamic SQL queries using any kind of string manipulation may expose your application to SQL injection security vulnerabilities.
Example:
#['SELECT * FROM $(vars.database default "dbtest").training.courses']
Actually, you can do a completely dynamic or partially dynamic query using the MuleSoft DB connector.
Please see this repo:

Also, I'm about to post an update that allows joins.
At a high level, this is a "Query Builder" where the code that builds the query is written in DataWeave 2. I'm working on another version that allows joins between entities, too.
If you have questions, feel free to reply.
One way to do it is :
Create a variable before DB Connector:
getTableName - ${env}.training.courses
Write SQL Query :
Select * from $(getTableName);
I am getting all the content from the table using following queries
SqlCmd.CommandText = "Select * from Product";
SqlCmd.connection = myConnection();
myConnection.open();
reader = sqlCmd.ExecuteReader();
As far I know when we use input parameters in select then there is possible attack of SQL injection. So how do we secure when we are not using where clause.
Can we prevent SQL injection using following query.
SqlCmd.CommandText = "Select Name from Product";
Injection occurs when placing variables in a query that user's can put code into. Users overwrite your statements and use their own (injection of SQL code). Your select query does not meet that criteria since users cant interact with it.
There should be some functions in ASP.net that allow you to premake statements. I don't use asp.net but a google search should help you know that your in the right direction.
As I read in a lot of articles, when I use JPA/Hibernate query it is good to set parameters in my queries so SQL injection is avoided. Like:
select user from User user where user.name = :name and user.surname = :surname
My problem is that in some cases I need to use native query when I create my query.
I will use my entity manager and createNativeQuery. But in this case the parameters will be positional. Like:
select * from users where user_name = ? and user_surname = ?
Then in my query I will use the method setParameter(1, "name") etc. So is this case "sql injection proof" like when in the parameterized query?
if you do not use string operations for building your query like
"SELECT foo FROM bar Where id="+myParameter+" more sql ..."
, then you will not have any vulnerabilities.
Currently (community correct me if I am wrong) no vulnerabilities exist within the latest PDO database abstraction layer.
However testing your queries for known and unknowns while sanitizing and filtering input will help eliminate the possibility of an injection in the event of a zero day exploit.
I currently use a combination of filtering input, charset expectations, stored procedures and strict requirements on their arguments prior to any and all dynamically created queries
This question might be lazy question. While I was using netbean to run query and also sql workbench then each time I run query and use it in .java file as
String sql = "select * from some table "+
"where table.col = 'sth'" //the query is not this short
Adding + and "" easily without going to each line and adding in 100 line of query.
Is there any way that netbeans or Oracle sql developer support direct export ast this kind of string or is there any other alternative.
Using Advance Format you can. HUrray! IN oracle SQl Developer
