Capitalize string in Sql Server

There is a very simple way to capitalize a string in Sql Server (T-SQL)

If your need is just in output, use this:

SELECT UPPER(LEFT(ColumnName,1)) + LOWER(SUBSTRING(ColumnName,2,LEN(ColumnName))) FROM TableName


If instead you need to modify and save values into db:

UPDATE ColumnName SET ColumnName=UPPER(LEFT(ColumnName,1)) + LOWER(SUBSTRING(ColumnName,2,LEN(ColumnName)))
