Perform INSERT with SELECT to insert multiple records

Question

In the diagram below there is a 1:1 relationship between \'DodgyOldTable\' and \'MainTable\'. Table \'Option\' contains records with \'OptionVal1\', \'OptionVal2\' and \'OptionV

Answer 1

perhaps not the most efficient solution but by using a union, this should work.

INSERT MainTable_Option ([MainTableID],[OptionID])
SELECT ID, (SELECT OptionID FROM Option WHERE OptionDesc = 'OptionVal1')
FROM DodgyOldTable dot
WHERE OptionVal1 = 'y'
UNION SELECT ID, (SELECT OptionID FROM Option WHERE OptionDesc = 'OptionVal2')
FROM DodgyOldTable dot
WHERE OptionVal2 = 'y'
UNION SELECT ID, (SELECT OptionID FROM Option WHERE OptionDesc = 'OptionVal3')
FROM DodgyOldTable dot
WHERE OptionVal3 = 'y'
