Convert SQL to ACCESS

Question

here is the regular SQL statement:

SELECT SUM(CASE WHEN [Column2] = 'Cylinder' THEN 1 ELSE 0 END) as 'Cylinder count',
SUM(CASE WHEN [Column2] = 'Snap' THEN 1 ELSE 0 END) as 'Snap count',
SUM(CASE WHEN [Column2] = 'Tip' THEN 1 ELSE 0 END) as 'Tip count',
SUM(CASE WHEN [Column2] = 'Other' THEN 1 ELSE 0 END) as 'Other count'
FROM [TableName]
WHERE [Column1] = '1.9 QNS-Quantity Not Sufficient'

can you convert it to ms-access?

Answer 1

Microsoft Access does not support CASE, but instead you can use IIF:

SELECT
    SUM(IIF([Column2] = 'Cylinder', 1, 0)) as 'Cylinder count',
    SUM(IIF([Column2] = 'Snap', 1, 0)) as 'Snap count',
    SUM(IIF([Column2] = 'Tip', 1, 0)) as 'Tip count',
    SUM(IIF([Column2] = 'Other', 1, 0)) as 'Other count'
FROM [TableName]
WHERE [Column1] = '1.9 QNS-Quantity Not Sufficient'
