    <p>I have a query string being built and it works fine when I use LIKE but it will not work with NOT LIKE</p> <pre><code> $sWhere = ""; if ( $_GET['sSearch'] != "" ) { $aWords = preg_split('/\s+/', $_GET['sSearch']); $sWhere = "WHERE ("; for ( $j=0 ; $j&lt;count($aWords) ; $j++ ) { if ( $aWords[$j] != "" ) { if(substr($aWords[$j], 0, 1) == "!"){ $notString = substr($aWords[$j], 1); $sWhere .= "("; for ( $i=0 ; $i&lt;count($aColumns) ; $i++ ) { $sWhere .= $aColumns[$i]." NOT LIKE '%".mysql_real_escape_string( $notString )."%' OR "; } } else{ $sWhere .= "("; for ( $i=0 ; $i&lt;count($aColumns) ; $i++ ) { $sWhere .= $aColumns[$i]." LIKE '%".mysql_real_escape_string( $aWords[$j] )."%' OR "; } } $sWhere = substr_replace( $sWhere, "", -3 ); $sWhere .= ") AND "; } } $sWhere = substr_replace( $sWhere, "", -4 ); </code></pre> <p>the part of the code that does work is:</p> <pre><code> if(substr($aWords[$j], 0, 1) == "!"){ $notString = substr($aWords[$j], 1); $sWhere .= "("; for ( $i=0 ; $i&lt;count($aColumns) ; $i++ ) { $sWhere .= $aColumns[$i]." NOT LIKE '%".mysql_real_escape_string( $notString )."%' OR "; } } </code></pre> <p>if I remove the "NOT" the query works fine but it does nothing when I add the NOT.</p> <p>thanks </p>

    1. COExplain `does nothing`. Obviously when you use `NOT LIKE` instead of `LIKE` you just get the opposite result set

    3. COI see a lot of code, but not a single query. Quite odd for a MySQL question...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
