integer primary/foreign key vs. varchar(255) primary/foreign key
Hello. Is there any principal performance (or some other) difference between using the integer primary/foreign key and using the string (varchar(255)) keys in queries that use tables joins? Server is Sybase SQL Anywhere 5.5.04 Yes! The primary key will only be made up of 12 bytes. By using an integer you ensure that your entire column is in the key. -- Jim Egan [TeamPS] Dynamic Data Solutions, Inc. http://www.dyn-data.com Houston, TX *********************************************************** Enterprise Applications in Your F...

Primary Keys containing common foreign keys from different tables
I have 2 tables Table 1 and Table 2 which have primary keys which include the same foreign key from a third Table 0. Table 1 has a primary key consisting of T1_KEY<pk> and T0_KEY<pk,fk>.

Keys, keys,keys...
Just installed PGP 6.5.8 and all is running fine, so far :-) Question: When I opened the PGP Keys window for the first time, apart from the *Create Key* wizard, there are about 50 odd keys belonging to various and sundry at NAI. Were these supplied for a purpose or only for illustration? Is there any reason they could not or should no be deleted? Question 2: I sent someone an encrypted test message using that person's public key. It went off fine except, I am left with only the encrypted eMail. What setting should I change in order for my eMail client (Outlook 2000) ...

Primary Key/Foreign Key
Can I use SQL Commands to add Primary key or reference keys to existed tables? (Not a new table, that's why I can't use CREATE TABLE command.) If does, could someone give me some sample codes? Thanks. Hi John, What you need is the ALTER TABLE statement. Look for it in SQLA help for the syntax. Regards, Nat.

SQL statement failed: (-194) No primary key value for foreign key
I'm getting this error message sporadically when my remote sites are replicating to my central server. The odd thing is the record that is the primary key value does exist! I'm at a lost...Does any have any idea, why this may be happening? Thanks Tasha Did the record exist at the time the error was reported? I have seen cases before where the Parent record is physically sent to the remote *after* the Child record. This would explain why the error was legitimately reported but when you look at the database later the Parent record now exists. -- -------------...

Error: Primary key for row in table 'x' is referenced by foreign key 'f' in table 'y'
(ASA 9 newest ebf) I'm getting this error even though mentioned foreign key has cascade updates (and deletes too) enabled. Is this some new behaviour in asa 9, or why can i get such message for cascaded foreign key? Any ideas? Thanks Pete Found a reason for it...but should it really work so? It's this way: - table a has columns a,b,c - table b has columns a,c, and references columns a,c (with a,c) in table a with cascade updates - table a hes before update trigger to change columns a when column b is changed (set new_row.a = ...) and that set new_row.a = ... i...
