# \$1strcasecmp
<a name="strcasecmp"></a>

The `$strcasecmp` operator in Amazon DocumentDB performs a case-insensitive comparison between two strings. It returns an integer value indicating the lexicographic comparison of the two input strings, ignoring case differences.

**Parameters**
+ `string1`: The first string to compare.
+ `string2`: The second string to compare.

## Example (MongoDB Shell)
<a name="strcasecmp-examples"></a>

This example demonstrates how to use the `$strcasecmp` operator to compare desk location strings in a `people` collection, ignoring case differences.

**Create sample documents**

```
db.people.insertMany([
  { "_id": 1, "Desk": "mke233-wi" },
  { "_id": 2, "Desk": "MKE233-WI" },
  { "_id": 3, "Desk": "mke233-wi" }
]);
```

**Query example**

```
db.people.aggregate([
  {
    $project: {
      item: 1,
      compare: { $strcasecmp: ["$Desk", "mke233-wi"] }
    }
  }
]);
```

**Output**

```
{ "_id" : 1, "compare" : 0 }
{ "_id" : 2, "compare" : 0 }
{ "_id" : 3, "compare" : 0 }
```

The output shows that the comparison between the `&quot;Desk&quot;` field and the string `&quot;mke233-wi&quot;` returns `0` for all three documents, indicating that the strings are equal when case is ignored.

  const db = client.db('test');
  const collection = db.collection('people');

  const result = await collection.aggregate([
    {
      $project: {
        item: 1,
        compare: { $strcasecmp: ["$Desk", "mke233-wi"] }
      }
    }
  ]).toArray();

  console.log(result);

  await client.close();
}
