I have defined
type
TDBType = (dbMySQL, dbMSSQL, dbSQLite, dbMSAccess);
const
arrDBProvider: array[TDBType] of string = ('MySQL', 'SQL Server', 'SQLite', 'Access') ;
But now I began wondering if there might be some type/const already defined that I could use. I haven't been able to find anything in manual or in the forum.
