Hi!
We have that huge query against a mysql 4.1 (myisam) to retrieve rows.
The query is built dynamically using a loop, as we are searching in an
external database built to store a tree with the nested tree model.
When we do this search with a normal world, it's fine: the query is around

Hi!
I'm stuck with a join query
2 tables, term and relation, the first one with definition of terms the
second one with the relations between them.
CREATE TABLE `term` (
`term_id` int(11) unsigned NOT NULL auto_increment,
`name` varchar(250) default NULL,
) ENGINE=MyISAM DEFAULT
Perfect!
I tried aliasing the field names but didn't think about the table, and was
just stuck looking at that query without any idea...
Thanks a lot for your help.

Hi,
I was wondering if there is any way to do a global search through all the
tables in mysql? (not taking into account the performance issue)
If for example I want to search ABC in all the columns of one table:
select * from table where [whatever the column] like '%ABC%'
or globally
select *
probably possible to do a small script describing all the columns
then building a query to search in, but I was wondering if there was
an already existing mechanism.
Another approach is not to use external scripts, but rather stored

Hi,
In your query you try to update on the condition column 1 = number2 and
column1 = number3.
I think what you want is column 1 = number2 or column1 = number3 .
If you use and it will try and found a record in column which has a value =
