I ran across an issue where a client had usernames that were all supposed to be lower but somehow wound up as a mixed case username.
\nThe SQL we would use would work out something like this…<\/p>\n
Select
\nNumber,
\nUsername,
\nLOWER(Username)
\nWHERE
\nUsername != LOWER(Username)<\/p>\n
To illustrate this here is the export specification that would return the above mentioned in TCC, name of file CandidateExportTestLower_sq.xml
