Can I have a SQL query to get the data from columna in tableA whose values don't start with 'f' ?
For example:
select * from tableA where columnA
where values don't start with letter 'F'.

In some situations, we may not want a space or another special character, so we can include the special character that we want to exclude in our not regular expression, such as [^A-Z0-9 ] to exclude a space.
To exclude columns, you use the REPLACE() and GROUP_CONCAT() functions to generate the column names you wish to include in your SELECT statement later. You can use the result to create your SELECT statement: SELECT address,age,email,id,name,phone FROM Students; And that's how you use the information_schema.
The SQL SELECT DISTINCT Statement The SELECT DISTINCT statement is used to return only distinct (different) values. Inside a table, a column often contains many duplicate values; and sometimes you only want to list the different (distinct) values.
For a MSSQL Scenario, you should be able to use the "NOT" operator in conjunction with the LIKE operator. So your SQL would look roughly like
select * from tableA where columnA NOT LIKE 'F%'
