Question 1

How do I connect NoClick to my PostgreSQL database?

Accepted Answer

Add a credential to the PostgreSQL node using either a full connection string in the form postgresql://user:password@host:port/database, or individual fields for host, port, database, username, and password. You can also set the SSL mode, which is required by most managed Postgres providers. The database must be reachable from NoClick's servers.

Question 2

Can I run parameterized queries to avoid SQL injection?

Accepted Answer

Yes. Both the SELECT query and the execute statement operations accept a separate parameters array, and you reference those values in your SQL as $1, $2, and so on. NoClick binds the parameters server-side, so values coming from upstream nodes are never concatenated into the query string. This is the recommended way to pass dynamic data from a form, webhook, or earlier node.

Question 3

What is the difference between the query and execute operations?

Accepted Answer

Run Select Query is for SELECT statements and returns rows as JSON, with a configurable row limit up to 10,000. Execute SQL Statement is for INSERT, UPDATE, DELETE, and other non-SELECT statements; it reports the affected row count and can optionally return rows when your statement includes a RETURNING clause. For very large result sets, the cursor-based query operation streams results in batches.

Question 4

Can the node manage database structure, not just data?

Accepted Answer

Yes. Beyond querying, the node can create and drop tables, schemas, indexes, and views, truncate tables, install extensions, and inspect structure with list-tables, list-columns, and get-table-info operations. It can also run maintenance operations like VACUUM and ANALYZE. This lets a workflow provision or clean up database objects as part of an automation.

Question 5

Does NoClick support PostgreSQL transactions?

Accepted Answer

It does. The node exposes Begin Transaction, Commit Transaction, and Rollback Transaction operations so you can group several statements into one atomic unit. If a step inside the transaction fails, you can route the workflow to a rollback so no partial change is left behind.
