"""delete from hai where ;""" means: delete all records from table hai for which the test is true. doing the same delete a second time means: delete nothing. which causes no error. also, if I was you I would avoid using a name like 'key' (a reserved word for other database systems -not sure what the standard says-) as an identifier. people more familiar with sqlite will tell you if it is a good idea to have a translation table with a key with type name 'text'. I would use 'integer'. hth, Mario - To unsubscribe, send email to [EMAIL PROTECTED] -

Narendran <[EMAIL PROTECTED]> was heard to say: > i am deleting ,it does delete. but i am trying to delete again, no error > code is returned, See http://www.sqlite.org/lang_delete.html: "If a WHERE clause is supplied, then only those rows that match the expression are removed." If no rows match the where clause, no rows will be deleted. This is not an error but the expected behaviour. regards, Markus -- Markus Hoenicka [EMAIL PROTECTED] (Spam-protected email: replace the quadrupeds with "mhoenicka") http://www.mhoenicka.de - To unsubscribe, send email to [EMAIL PROTECTED] -

[sqlite] problem in deleting
hi ,
i got a confusion in deleting a entry,
sqlite> create table hai (key text primary key,value text) ;
sqlite> create table hai (key text primary key,value text) ;
SQL error: table hai already exists
sqlite> insert into hai (key,value) values ('hai1','value1');
sqlite> insert into hai (key,value) values ('hai1','value1');
SQL error: column key is not unique
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = 'hai1';
sqlite> insert into hai (key,value) values ('hai1','value1');
sqlite> insert into hai (key,value) values ('hai1','value1');
SQL error: column key is not unique
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = hai1;
SQL error: no such column: hai1
sqlite> delete from hai where key = hai1;
SQL error: no such column: hai1
sqlite> delete from hai where key = hai1;
SQL error: no such column: hai1
sqlite> delete from hai where key = 'hai1';
sqlite> delete from hai where key = 'hai1';
sqlite>
i think ,it should delete the record,it doesn't delete,with api's or thro
shell.
please do tell me what am i doing wrong
Thanks & Regards
Narendran B
