Hi all,
I did the code for searching video.
My purpose is the user may enter
Type, Title or Actor, or either any
two of them, or all of them.
The code can work individually, but
after put them together, it only works on
last query which to enter all of them
three. Could anyone give any idea?
Thanks in advance!!
Code:
<%
if( VideoType == "ALL" )
{
if( VideoTitle == "" )
{
if( VideoActor == "" ) {
strSQL = "SELECT ISBN, V_Title, V_Type,
V_Actor, V_Time FROM
Video_Catalog";
}
else {
strSQL = strSELECT + "V_Actor = '" +
VideoActor + "'";
}
}
else
{
if( VideoActor=="" ) {
strSQL = strSELECT + "V_Title = '" +
VideoTitle + "'";
}
else {
strSQL = strSELECT + "V_Title = '" +
VideoTitle + "' AND V_Actor = '" +
VideoActor + "'";
}
}
}
else
{
if( VideoTitle=="")
{
if( VideoActor==""){
strSQL = strSELECT + "V_Type = '" + VideoType
+ "'";
}
else{
strSQL = strSELECT + "V_Type = '" + VideoType
+ "' AND V_Actor = '" + VideoActor
+ "'";
}
}
else
{
if( VideoActor==""){
strSQL = strSELECT + "V_Type = '" + VideoType
+ "' AND V_Title = '" + VideoTitle
+ "'";
}
else {
strSQL = strSELECT + "V_Type = '" + VideoType
+ "' AND V_Title = '" + VideoTitle +
"' AND V_Actor = '" + VideoActor + "'";
}
}
}
%>
<% rs = statement.executeQuery( strSQL ); %>
