注意

Please note, in Proton 1.3.27 or the earlier versions, SQL functions were case-sensitive and always in lower-case. Since 1.3.28, function names are case-insensitive. For example count, COUNT and Count work in the same way. SQL Keywords such as SELECT or FROM are case-insensitive too. In the rest of the documentation, we use function names in lower case for demonstration. Since 1.3.28, function names are case-insensitive. For example count, COUNT and Count work in the same way.
