最初我试图加入长文本和超链接,以及短文本等。当从查询中删除字段时,连接起作用。但是在更改字段(长文本到短文本和超短链接到短文本)并重新引入查询后,查询仍然会出现相同的错误。
SELECT products1.*
FROM products1
LEFT JOIN Products
ON (products1.Category = Products.Category)
AND (products1.[Minimum Reorder Quantity] = Products.[Minimum Reorder Quantity])
AND (products1.Discontinued = Products.Discontinued)
AND (products1.[Quantity Per Unit] = Products.[Quantity Per Unit])
AND (products1.[Target Level] = Products.[Target Level])
AND (products1.[Reorder Level] = Products.[Reorder Level])
AND (products1.[List Price] = Products.[List Price])
AND (products1.[Standard Cost] = Products.[Standard Cost])
AND (products1.ID = Products.ID) AND (products1.[Product Name] = Products.[Product Name])
AND (products1.[Product Code] = Products.[Product Code])
WHERE (
