Re: need help urgent
Hi Rakaha, You have a cursor , select id from table_name and then have a loop where in you select values of LTA for each id got from the above cursor, close the loop once all the ID have been processed. regards anandk On 3/30/07, raksha [EMAIL PROTECTED] wrote: How to retrieve data from three consecutive tuples until th end of the database.Such that suppose the field name is ID and I want to retrieve data from another field LAT such that at a time LAT values for ID's 1,2,3 are taken then for 3,4,5 then for 4,5,6 so on till table ends. -- View this message in context: http://www.nabble.com/need-help-urgent-tf3491135.html#a9749875 Sent from the MySQL - General mailing list archive at Nabble.com.

Or you could also do this. SELECT LTA FROM TABLE A WHERE ID IN (SELECT B.ID FROM TABLE B); i hope this what your looking at, please let us know. regards anandkl On 3/30/07, Ananda Kumar [EMAIL PROTECTED] wrote: Hi Rakaha, You have a cursor , select id from table_name and then have a loop where in you select values of LTA for each id got from the above cursor, close the loop once all the ID have been processed. regards anandk On 3/30/07, raksha [EMAIL PROTECTED] wrote: How to retrieve data from three consecutive tuples until th end of the database.Such that suppose the field name is ID and I want to retrieve data from another field LAT such that at a time LAT values for ID's 1,2,3 are taken then for 3,4,5 then for 4,5,6 so on till table ends. -- View this message in context: http://www.nabble.com/need-help-urgent-tf3491135.html#a9749875 Sent from the MySQL - General mailing list archive at Nabble.comhttp://nabble.com/ .

Can you please describe exactly what you mean with a 'hang' ? - Does the connection in your test program stop respoding ? - Can you connect to mysqld with other clients ? - Does the MySQL server take all cpu In the tests directory of the MySQL source tree there is a test program 'client_test' that shows in detail how to use prepared statements with MySQL. A (Note that If I didn't run this coding or my COBOL coding the Server remain A function properly) A Kindly suggest me the solution or quote me the things i forgot to do... In the released 5.0 server there is some known bugs in the prepared statement handling for some specific prepared statements. We have fixed these bugs in 4.1.2 which should be available quite soon (we are just now closing the last open bugs in 4.1 to be able to make a new release ASAP). To get any problems you have fixed, you could try to make a standalone test case in C that we could try to repeate. Another option is to follow the instructions in the MySQL manual of how to debug MySQL and give us a stack trace of where mysqld is hanging. Another option is to use the debug version of mysqld and start it with --debug. The trace file that is written (in C:\ or /tmp) should give us a good idea of where the bug could be.
