# Logical-and &, and

{% hint style="info" %}
The logical operator **`&`** (**`and`**) checks if two conditions both evaluate to true.\
The operators **`&`** and **`and`** can both be used and are exactly the same.

*If used together with the logical* `or` *operator, the precedence is important:* **`and`** *takes precedence over* `or`*. We strongly advice to use (parentheses) to correctly group these logical statements.* 

This function is SQL compatible. For more information about SQL compatibility, see our [documentation](/platform/wemreference/sql-compatibility.md).
{% endhint %}

{% hint style="success" %}
The result is a Yes/No value, depending on the check

* if `Condition1` evaluates to `true` AND `Condition2` evaluates to `true`, only then <mark style="color:green;">`Yes`</mark> is returned.
* all other evaluations result in <mark style="color:red;">`No`</mark>
  {% endhint %}
