mysql查询以获取特定日期之间的用户详细信息

Question

$query="SELECT DISTINCT ind_id,indentdate,submitted_by 
        FROM raiseindent 
        where submitted_by='$nm' 
          AND indentdate BETWEEN '$fromDate' AND '$toDate' 
          OR indentdate BETWEEN '$fromDate' AND '$toDate' 
          OR submitted_by='$nm'";

here $nm is username

I am not getting any errors, this query fetching records if I use only $nm (User Name) or between two dates

If I use to serach specific user name and two dates it is fetching all users records between selected dates

I need specific only the results from entered user name in username field to serach

Answer 1

Try this

$query="SELECT DISTINCT ind_id,indentdate,submitted_by 
        FROM raiseindent 
        where submitted_by='$nm' 
          AND indentdate BETWEEN '$fromDate' AND '$toDate'";

I dont think it need to be any more complicated than this.

Or if it is possible for $nm to be empty or the dates to be empty then do those tests in PHP and dynamically build the query accordingly rather than trying to get the SQL to do it all for you

$sql = 'SELECT DISTINCT ind_id,indentdate,submitted_by 
    FROM raiseindent 
    WHERE ';


if ( !empty($nm) && $nm != 'ALL' ) {
    $sql .= "submitted_by='$nm' AND ";
}
if ( !empty($fromDate) && !empty($toDate) ) {
    $sql .= " indentdate BETWEEN '$fromDate' AND '$toDate' ";
}
$sql = rtrim($sql, 'AND ');

Answer 2

Though it's already answered; for a note try using >= and <= to have the exact start and end date inclusive, instead BETWEEN operator like

SELECT DISTINCT ind_id,indentdate,submitted_by 
        FROM raiseindent 
        where submitted_by='$nm' 
          AND (indentdate >= '$fromDate' AND indentdate <= '$toDate');
