Concat fields

Multiple Connections
Good morning to all. I am using the mySQL connector to connect to the mySQL database. My question concerns the session between the DB and the client. How is the session maintained? In other words, how does the DB know that it is communicating with my specific connection? Here is why I ask. In a test under JAVA I create 2 different Connection objects. I verify that they are not the same Java object. I looked at the code for my driver and at it's heart, when I call for a new connection the code looks like it creates a new one and doesn't reuse an existing one. I'm not positive about this yet. If I create these two supposed connections and insert into a table with one, both connections read the same last_insert_ID() value. This tells me that the DB is treating my connections as the same connection. I need to know if the problem is that MySQL is caching and reusing any connection from my client OR if the problem is with my driver. Thank you for insights. God Bless Paul C.

Unique Key question
Good morning. I have a table with field name DATA type tinytext. The table is already populated. I need DATA to be unique. It seems that MySQL doesn't look at the uniqueness of a field in a binary fashion. Example (chosen because I think it is just plain odd) june = Júne If I query as - Select * from myTable where DATA = 'june' - I am returned both. If I query as Select * from myTable where cast(DATA as binary) = 'june' - I am returned only one. How can I set this table so that the unique key is based on the binary value of the field? Do I have to alter the field type or is there a better way? Thank you. God Bless Paul C. McNeil Developer in Java, MS-SQL, MySQL, and web technologies.

Very strange database behavior
Good morning to all.
I have a very strange problem in my database and am trying to track down
whether it is a JAVA problem or a mySQL problem.
I have a table that is supposed to accept only unique data, however, at this
time, the PK for that information is set to the auto incrementing ID field.
The unique field is called 'pat'. Here is a description of the problem.
I have a class that posts data to the pat field using java
preparedStatements. The statement executes like this
// test that the insert is unique
SELECT ID from table where pat = 'MyValue';
// If that comes back with an ID, no insert is made
// No ID means we insert.
if(NoIdReturned){
INSERT INTO table(pat) Values('MyValue');
// I have added a test here to insure that the
// data was inserted
// I perform the same query as above
// This is not in the production code.
SELECT ID from table where pat = 'MyValue';
// In tests this comes back with a value every time.
// The production code gets the last_insert_id()
Select last_insert_id() as myID;
// In tests this value and the one above always match.
}
OK. Here's the oddity, you would think that if I run this class again with
the same parameter for MyValue, the flow would be...
test for MyValue..
test returns IDExists
No insert happens.
That's not what is happening. If I run the class...
once - Insert happens
twice - Insert happens
3 times - ID is found and no insert happens.
Oddity #2 - In test 2, the first query returns no ID.
After the insert I ask for last insert ID and get 1234.
I ask for the ID using the SAME query that returned me NO ID and I get 1233,
the ID of the first insert.
I have tested this as many ways as I can think. The insert is NOT a delayed
insert. I have tried spacing out the tests. I have checked the DB using
MySQLCC AND using the query that my test prints to screen and the first
insert is always happening. Below are the actual test results from run#2.
// Query to see if the data exists.
SELECT ID from Rules where pat = 'AUTO\\_DOGGY';
Identity is -1 because no rows exist.
AUTO_DOGGY Identity was -1
// Insert the rule
Inserting new rule.AUTO_DOGGY
// test
Testing for AUTO_DOGGY
// Same query as above
SELECT ID from Rules where pat = 'AUTO\\_DOGGY';
// Below LIID = Last_Insert_ID()
// Query ID is what is returned from query
LIID = 124566 Query ID = 124565

RE: Very strange database behavior
Thanks for the response.
There is currently no primary key on the field so I am relying on the data
being there, or not being there, to decide whether it is safe to insert the
new data.
Through MySQLCC, have_query_cache = YES. Is this the variable I am looking
for? What affect would this have?

Hi
I have a fulltext search on a dbase for lost pets.
My problem is the following:
I have dog in the database called May May which doesnt show up in the
search results. A dog called Doggy Doggy does show up however. I
guess the problem is that MySql sees May May as being a date or
something and doesnt do a text compare.
Here is my query, from php.
$query_results = sprintf(SELECT * FROM dogslost WHERE MATCH
(`name`,`colour`,`gender`,`breed`,`location`,`description`) AGAINST
('%s' IN BOOLEAN MODE), $crit_results);
any ideas?

I have so far:

The statement executes successfully, and the data is inserted. However
the above line that fetches the last_insert_id value from MySQL always
returns undef. The table has an auto_increment column. What's going on?

I have never done anything like this but after looking at the spec's I have a possible direction for you In String functions there is LOCATE(substr,str,pos) The first syntax returns the position of the first occurrence of substring substr in string str. The second syntax returns the position of the first occurrence of substring substr in string str, starting at position pos. Returns 0 if substr is not in str.

Select double value
Good morning to all. I have a problem with a workaround but I wanted to know if others have run into this. Table DATA Column strength [double] When I select strength from DATA and the result is a non zero amount it returns correctly 3.256498 however if it is a 0 amount I get 0. The problem is that in my java.sql.ResultSet.getDouble(strength) a zero amount throws a number format exception. SO, I placed a conditional SELECT CASE WHEN strength IS NULL OR strength = 0 THEN 0 ELSE strength END This, however seems to truncate the result so that a zero return results in 0 BUT a return of 3.1236564 results in 3. Bummer. Finally I had to restructure my conditional... SELECT CASE WHEN strength IS NOT NULL AND strength != 0 THEN strength ELSE '0' END I feel that this type of data manipulation shouldn't need to be done. Is this a bug or normal for a return type of double? Thanks. Good days to all. GOD BLESS AMERICA!
