How do I find the id of an auto_increment column when using a MySQL database?

How do I define an AUTO_INCREMENT column that generates unique indentifiers for a table?

Mckoi SQL Database - Frequently Asked Questions (FAQ)
Use the UNIQUEKEY(table_name) function. For example, INSERT INTO MyTable ( my_unique_id, my_value ) VALUES ( UNIQUEKEY('MyTable'), 'record value' ) With a clever use of the DEFAULT clause when creating a table you can make it automatic. eg. CREATE TABLE MyTable ( my_unique_id NUMERIC DEFAULT UNIQUEKEY('MyTable'), my_value LONGVARCHAR(1000) ) The UNIQUEKEY function is an atomic operation that will return a set of sequential numbers for a table on a first serve basis.

What are the advantages of using a 3.0mm ID HPLC column for LCMS?

MicroSolv Technology Corporation
Many scientists use a 2.1mm ID and smaller columns for LCMS which have optimal flow rates of approximately 0.3ml/min. This is fine for isocratic analysis but when you must use a gradient method, specialized pumps and mixing valves are necessary that can reproduce the very small changes in the mobile phase's composition. 3.0mm ID columns use more traditional flow rates and can be used easily on LCMS without specialized pumps for both gradient and isocratic methods.
