Remove Trailing Spaces and Update in Columns in SQL Server

Question

I have trailing spaces in a column in a SQL Server table called Company Name.

All data in this column has trailing spaces.

I want to remove all

Answer 1

To just trim trailing spaces you should use

UPDATE
    TableName
SET
    ColumnName = RTRIM(ColumnName)

However, if you want to trim all leading and trailing spaces then use this

UPDATE
    TableName
SET
    ColumnName = LTRIM(RTRIM(ColumnName))
