search and existing sql WHERE clause

search and existing sql WHERE clause

I have a search setup and working. I was hoping to limit the results simply by using a WHERE in the database sql.

ie. SELECT * FROM content WHERE pagecategory = ?

However, existing WHERE clauses in the sql are ignored by DA search (cannot exclude anything from the search pool).

Is there something I need to be aware of here, or I am missing?

Add it as a criteria to the data assist search behavior so it will be included in the where clause that data assist search creates.

Had tried that, but couldn't get that to return properly either:

WADbSearch3_whereClause=BuildFilterString("pagecategory","do_not_show_on_menu","AND NOT","Includes",0,WADbSearch3_wildCard,WADbSearch3_dateSeparator,WADbSearch3_whereClause)

it looks like the criteria you are using is AND NOT Includes do_not_show_on_menu


from the SQL example, it looks you should be using
AND Equals do_not_show_on_menu

sorry, the original sql was an exclude (SELECT * FROM content WHERE pagecategory <> ?). I was just trying a few options to see if I could include/exclude anything at all.

problem is, none of the filters in the DA criteria seem to factor (excluding or including). My limits were simple... so was just going to do that in the sql, but that is ignored as well.

the <> operator is NOT EQUALS, send a copy of your page so i can see the entire code to offer debugging advice.

again, trying to exclude certain pages from showing in the search results.

searching works fine, but cannot exclude anything. Tried in the sql statement, and with DA filters. thanks.

to see the sql that is being generated, add the following code after the <body> tag:


SQL: <%=searchresults_pages_cmd.CommandText %>


post the results back please.

here it is...

SELECT * FROM content_cnt WHERE pagecategory <> ? AND ((pagecategory LIKE '%contact%')) OR ((pagesection LIKE '%contact%')) OR ((cont_cnt LIKE '%contact%')) OR ((subsection LIKE '%contact%')) AND NOT (pagecategory LIKE '%do_not_show_on_menu%')

well, it is adding both of the conditions to the where clause, your initial where clause is not being ignored, it is being added in.



this section:
WHERE pagecategory <> ?


is initial where clause, and this one:
AND NOT (pagecategory LIKE '%do_not_show_on_menu%')


is the new criteria that you added. Is "do_not_show_on_menu" the actual value that is stored in that column?
