• Listing both null and not null in mysql query

  - by tomasz

  Let's say I have the table NAME | ID | REF foo1 | 1 | NULL foo2 | 2 | 1234 foo2 | 3 | 567 foo1 | 4 | NULL foo3 | 5 | 89 I'd like to count all instances of NULL and NOT NULL in one query so that I can say NAME | null | not null foo1 | 0 | 2 foo2 | 2 | 0 foo3 | 0 | 1 I could run these two queries select NAME,count(*) from TABLE where REF is not null select NAME,count(*) from TABLE where REF is null But I'm sure there must be a simple way to do it in one mysql query.

• Convert MYSQL Timestamp to time_t

  - by Kewley

  I'm writing a multi-threaded program that needs to be able to check if a row requires updating and act accordingly. I had problems using the built in date/time functions of MySql and so decided to just store the "lastupdate" timestamp as an integer in the table. However, I'm having problems converting this timestamp to time_t so that I can use the time functions with it. Any help is greatly appreciated.

• MySQL auto increment

  - by mouthpiec

  Hi, I have table with an auto-increment field, but I need to transfer the table to another table on another database. Will the value of field 1 be 1, that of field 2 be 2, etc? Also in case the database get corrupted and I need to restore the data, will the auto-increment effect in some way? will the value change? (eg if the first row, id (auto-inc) = 1, name = john, country = UK .... will the id field remain 1?) I am asking because if other table refer to this value, all data will get out of sync if this field change.

• NHibernate and mysql timestamp

  - by HeavyWave

  I am trying to do versioning with NHibernate and everything works fine, however right after the insert NHibernate tries to pull the generated timestamp by executing the following query: SELECT profileloc_.Updated as Updated14_ FROM profile_locale profileloc_ WHERE profileloc_.id=?p0 and profileloc_.culture=?p1;?p0 = 16, ?p1 = 1033 Which is totally wrong, as it will pull out all versions starting with the first one. How do I make it add ORDER BY Updated DESC to this query? I am using Fluent NHibernate for mappings.
