First, let me start off by saying I do not like the use of Triggers.  That said, I do not know of any other option at this point.  I need a temporary solution to the following problem and came up with the use of a Trigger.

The issue I have is I am calling an API and sending a request that will insert the following information into a mysql table.  The API is limited and does not allow one of the columns fields to accept what I need.  The data inserted comes in as -2 everytime and I need the data to be set from a related table. I though a Before Insert Trigger based on if the field = -2.  The field would then be set with information from the related table based on the matching field.  Here is some more info to clarify this:

Table 1 (Data being Inserted)
field 1 = "name"
field 2 = "-2"

Table 2
field 1 ="name" (matches field 1 on table 1)
field 2 = "75"

When an INSERT is performed, the Trigger will replace the incoming -2 data and use the related info from Table 2, field 2 using field 1 as a match.

I hope this information is enough for someone trying to help with this.  I am having trouble figuring if this should be a BEFORE or AFTER Trigger as well as limiting it to working when field2 on Table 1 is = -2.

This is also temporary until the API being used can accept Field 2 as a variable on the original request.
