• How to get multiple counts with one SQL query?

  - by Crobzilla

  I am wondering how to write this query. I know this actual syntax is bogus, but it will help you understand what I am wanting. I need it in this format, because it is part of a much bigger query. SELECT distributor_id, COUNT(*) AS TOTAL, COUNT(*) WHERE level = 'exec', COUNT(*) WHERE level = 'personal' I need this all returned in one query. Also, it need to be in one row, so the following won't work: 'SELECT distributor_id, COUNT(*) GROUP BY distributor_id'

• Using many mutex locks

  - by hanno

  I have a large tree structure on which several threads are working at the same time. Ideally, I would like to have an individual mutex lock for each cell. I looked at the definition of pthread_mutex_t in bits/pthreadtypes.h and it is fairly short, so the memory usage should not be an issue in my case. However, is there any performance penalty when using many (let's say a few thousand) different pthread_mutex_ts for only 8 threads?

• T-SQL get SELECTed value of stored procedure

  - by David

  In T-SQL, this is allowed: DECLARE @SelectedValue int SELECT @SelectedValue = MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1 So, it's possible to get the value of a SELECT and stuff it in a variable (provided it's scalar, obviously). If I put the same select logic in a stored procedure: CREATE PROCEDURE GetMyInt AS SELECT MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1 Can I get the output of this stored procedure and stuff it in a variable? Something like: DECLARE @SelectedValue int SELECT @SelectedValue = EXEC GetMyInt (I know the syntax above is not allowed because I tried it!)

• Semantic #region usage

  - by Luca

  What's your opinion about using #region folding using application semantic, instead of folding for "syntax". For example: #region Application Loop #region User Management #region This Kinf of stuffs instead of #region Private Routines #region Public Properties #region ThisRoutine // (Yes, I've seen this also!) In this logic, I'm starting fold even routine bodies. I'm starting to love #region directive (even using #pragma region when using C++!).

• How do you store a result to a variable and check the result in a conditional?

  - by Oesor

  I know it's possible but I'm drawing a blank on the syntax. How do you do something similar to the following as a conditional. 5.8, so no switch option: while ( calculate_result() != 1 ) { my $result = calculate_result(); print "Result is $result\n"; } And just something similar to: while ( my $result = calculate_result() != 1 ) { print "Result is $result\n"; }
