## APOC mappings

This table shows the mapping between APOC functions/procedures and their Memgraph equivalents. Use these mappings if you're familiar with Neo4j's APOC library.
When switching from Neo4j to Memgraph, application code that calls `apoc.*` or `gds.*`
procedures and functions would otherwise break, since Memgraph exposes the same
functionality under different names. The aliases below serve as a drop-in replacement for
those APOC and GDS calls, so you can migrate without changing your application code.

This table shows the mapping between APOC functions/procedures and their Memgraph equivalents.
Use these mappings if you're familiar with Neo4j's APOC library.

### Inspecting configured mappings

Memgraph loads callable aliases from the JSON file pointed to by the
[`--query-callable-mappings-path`](/database-management/configuration) flag.
To list every alias currently registered (including any custom mappings you
add to that file), run:

```cypher
SHOW QUERY CALLABLE MAPPINGS;
```

The query returns three columns:

- `alias_name: string` ➡ The name clients call (for example, `apoc.version`).
- `source_name: string` ➡ The underlying Memgraph procedure or function the
alias resolves to (for example, `mgps.version`).
- `type: string` ➡ Either `procedure`, `function`, or `unknown` if the source
cannot be resolved.

Running `SHOW QUERY CALLABLE MAPPINGS` requires the `CONFIG` privilege.
