Search Help with CONCAT command

Software: Dreamweaver CS4
Extension: DataAssist 2.08

Hello, my database 'Notes' table have
'date' type called 'note_Day' and
'time' type called 'note_EndTime'
I use CONCAT command from sql to get the complete date as end time in search page.

CONCAT(Notes.note_Day,' ',Notes.note_EndTime) AS Date_Note

But I get the message:
Unknown column 'Date_Note' in 'where clause'

How I can solve this trouble ?

using:
CONCAT(Notes.note_Day,' ',Notes.note_EndTime) AS Date_Note

Creates a table alias named "Date_Note" table alias's cannot be used in the where clause since they arent returned until the query executes, an alias is part of the result set, not the actual table.

Any concatenation will need to happen directly in the where clause, change:

php:
$WADbSearch1->addComparisonFromEdit("Date_Note","S_note_FromDate","AND","Begins With",2);

  $WADbSearch1->addComparisonFromEdit("Date_Note","S_note_ToDate","AND","Ends With",2);



to:

php:
$WADbSearch1->addComparisonFromEdit("CONCAT(Notes.note_Day,' ',Notes.note_EndTime)","S_note_FromDate","AND","Begins With",2);

  $WADbSearch1->addComparisonFromEdit("CONCAT(Notes.note_Day,' ',Notes.note_EndTime)","S_note_ToDate","AND","Ends With",2);
