          UPPER

          UPPER

          Converts all letters in the specified text string to uppercase.

          Any characters that are not letters are unaffected by this function. Locale rules are applied if a locale is provided.

          Use

          UPPER(text, [locale]) and replace text with the field or expression you wish to convert to uppercase, and locale with the optional two-character ISO language code or five-character locale code, if available.

          MYCOMPANY.COM Example

          Turkish Language Locale Rules Example
          Turkish Language Locale Rules Example

          The Turkish language has two versions of the letter i: one dotted and one dotless. The locale rules for Turkish require the ability to capitalize the dotted i, and allow the dotless I to be lowercase. To correctly use the UPPER() function with the Turkish language locale, use the Turkish locale code tr in the UPPER() function as follows:

          UPPER(text, "tr")

          Using this locale code ensures that Salesforce doesn’t transform any dotted i in the text to a dotless I.
