Question

I have two mysql tables which both have a typeID in common. I am wanting to select everything from these two tables with the same typeID, query below:

SELECT ta.requiredTypeID, ta.typeID, ta.quantity 
  FROM `invtypes` as t, `typeactivitymaterials` as ta 
  WHERE volume > 0 AND t.typeID = ta.typeID;

This gives me the correct results but I am trying to export this query as insert statements. I have tried adding INTO OUTFILE “/path/” but this only exports the data as tab/comma delimited data, is it possible to export this data as insert statements?

Cheers

You can combine INSERT with SELECT to insert records directly from the result of a select statement.

The way you do it would be something like this:

INSERT INTO newtable (requiredTypeID, typeID, quantity)
     SELECT ta.requiredTypeID, ta.typeID, ta.quantity 
         FROM `invtypes` as t, `typeactivitymaterials` as ta 
         WHERE volume > 0 AND t.typeID = ta.typeID;

Here’s a link to the relevant MySQL manual page.

Note that this would actually do the insert right away; it wouldn’t do quite what you asked (which is to generate the insert statements for use later on).
