David, what you're looking for is pivot table functionality. Unfortunately, that is not a built-in feature for MySQL (it is for SQL Server 2005/2008). Not knowing your table structure, or the size/number of rows/columns, I found the following link to be most helpful example: MySQL Pivot Table Example
You need to have two tables. One table for the reservation (each reervation having a primary key) and one table to store the people "linked" to that reservation. In the second table, each person will be on a row and one column in your second table would refer to the first (reservation) table in a one-to-many relationship. Read into database design and this will make sense. This can all be done in ADO.NET.
A trigger is a special kind of stored procedure that automatically executes when an event occurs
in the database server. A trigger is really an event handler.
SQL Server allows users to create triggers (event handlers) for 3 types of events:
DML Event - Occurs when a DML (Data Manipulation Language) statement: INSERT, UPDATE or DELETE,
DDL Event - Occurs when a DDL (Data Definition Language) statement: CREATE, ALTER, or DROP,
Logon Event - Occurs when a user logins to the Server.
There are 3 different types of triggers (event handlers) based on the types of events they are triggered by:
DML Trigger - Executes in response to a DML event.
DDL Trigger - Executes in response to a DDL event.
Logon Trigger - Executes in response to a logon event.
Generally database updates either require a commit to have the database perform the appropriate checking and actually flag the rows as part of the database. That Commit can occur in two ways -- some databases can be setup with an auto commit or auto rollback when the database is disconnected. The first means the programmer needs to do nothing. The second means if the programmer does not commit the updates are backed out of the database. To commit is generally considered bad because if there are any data errors partial transactions and logically inconsistent contents can exist in a database. For example entering an order for merchandise requires a single header row to identify the customer and multiple items rows to indicate what was ordered. If the third item record added to an order had an error and the application did not rollback and the database auto committed and incomplete order with only two items would be saved in the database. Traditionally databases with an automatic action at shutdown are set to rollback to assure such partial information is not saved. Even with auto rollback good programs detect errors and rollback themselves and allow users to continue.
The net result of the above is the probability that if the inserts actually occurred as you believe the there was a missing commit to confirm their addition to the database. and an automated rollback kept them from being completely added to the database. Another alternative is that the insert was not error checked in the program code and it failed meaning despite the program counter claiming rows were inserted in fact they were not.
