Unknown column in 'where clause?

Question

I Have the following code of php

        $query = sprintf("SELECT to_go.to_location FROM to_go 
                INNER JOIN to_location ON to_go.to_location_id = to_location.id 
                    WHERE match(to_location ) against(%s)", mysql_real_escape_string($location));

i tried every thing but it keep output me that following error "Unknown column in 'where clause ?" i tried to change the names of the columns and still the same problem

Answer 1

match(to_location ) against需要提供一个字段，而不是一个表：

match(to_location.id) against(something)

Answer 2

I guess you may need to replace

WHERE match(to_location )

with

WHERE match(to_go.to_location)

Answer 3

Since you have a column name the same name as a table name, MySql is probably confusing them and thinking match(to_location) refers to the table. Try using the fully-qualified column name, ie, table_name.column_name .
