How to query Soql not like?

Regarding Soql not like -

You have your parentheses wrong.
Instead of:
NOT(Field__c LIKE 'fuzzymatch')
Use:
(NOT Field__c LIKE 'fuzzymatch

In Salesforce Object Query Language (SOQL), the LIKE operator is used to perform wildcard searches on text fields, similar to SQL. However, SOQL does not directly support a NOT LIKE operator. To achieve the functionality of NOT LIKE, you can use a combination of the NOT operator with LIKE, or you can use the EXCLUDES operator if dealing with multi-select picklists.

Here's how you can construct queries to simulate NOT LIKE in SOQL:

Using NOT with LIKE

SELECT Id, Name FROM Account WHERE Name NOT LIKE 'Test%'

Using NOT with INCLUDES for Multi-Select Picklists

If you are working with multi-select picklist fields, you can use NOT with INCLUDES.

Example: Query for accounts where the multi-select picklist field Industry does not include 'Technology'.

SELECT Id, Name FROM Account WHERE NOT (Industry__c INCLUDES ('Technology'))

Using NOT with Wildcards

SOQL supports the % wildcard to represent zero or more characters and the _ wildcard to represent a single character.

Example: Query for accounts where the Name does not contain 'Corp'.

SELECT Id, Name FROM Account WHERE Name NOT LIKE '%Corp%'
Using != for Exact MatchesIf you need to exclude exact matches, you can use the != operator.

Example: Query for accounts where the Type is not 'Customer'.

SELECT Id, Name FROM Account WHERE Type != 'Customer'

Combining Multiple Conditions

You can combine multiple conditions using AND and OR to create complex queries.

Example: Query for accounts where the Name does not contain 'Corp' and the Type is not 'Customer'.

SELECT Id, Name FROM Account WHERE Name NOT LIKE '%Corp%' AND Type != 'Customer'

Summary

While SOQL does not have a direct NOT LIKE operator, you can achieve the desired results by using NOT with LIKE or other logical operators depending on your specific needs. Here are the key points:
