It's just that you have to break the query up and segregate the query to LONGDESCRIPTION on its own if you are writing ODBC queries for PHP.Just a quick note for anyone else who found ODBC_NUM_RESULTS normally reliable otherwise but inexplicably always returning -1 under certain ...

even if you have MySQL 4.1 or later, it's not a bad idea to examine queries that you might be inclined to write in terms of subselects; a join is sometimes more efficient than a subselect.
When you make it part of another query however, ODBC_NUM_ROWS will always return -1. The solution is to keep any queries to LONGDESCRIPTION in a separate standalone query by itself. However, if you run the query though a previewer like Toad for DB2, using LONGDESCRIPTION in a larger ...
Then, either enter a pattern for string matching, or a value range, for range filtering. When using a pattern match, you can set checkmarks according to whether the pattern contains wildcards or is a regular expression. Wildcard patterns contain '*' (matching any sequence of characters) and...
Receiving extraneous articles in response to a query submitted to MEDLINE/PubMed is common. When submitting a multi-word query (which is the majority of queries submitted), the presence of all query words within each article may be a necessary condition for retrieving relevant articles, but not...
Using WHERE in Your QueriesYou have learned numerous ways to retrieve particular columns from your tables, but not specific rows. This is when the WHERE clause comes into play. From the basic SELECT syntax, you see that WHERE is used to specify a particular condition:...
DNS1 then queries DNS2, which returns an address of 201.114.37.5. When this DNS message passes through the NAT, the address is translated to 10.1.3.1, and DNS1 passes this address on to host A. Host A then sends packets to this address, and the NAT translates the source and ...
