I have a table named 'user'.I need to update the field 'email' .Is there any custom build queries for updating.I have only the uid of user.
I mean.. Is there any typo3 custom queries equivalent to
Update table 'user' set email = 'firstname.lastname@example.org' where uid = 1;
$query = $this->createQuery();
Why don't you use
exec_UPDATEquery ( $table, $where, $fields_values, $no_quote_fields = false )
Please refer exec_UPDATEquery From TYPO3
