sql 语句中where条件和jion on条件的区别
与有很大的差别，请注意！
SELECT TBL_SchemaDetail.MaterialNo, TBL_StockMaterial.SalePrice FROM TBL_StockMaterial RIGHT OUTER JOIN TBL_SchemaDetail ON TBL_StockMaterial.MaterialNo = TBL_SchemaDetail.MaterialNo AND TBL_SchemaDetail.SchemaNo = '7411' AND TBL_StockMaterial.SalePrice = 0
条件全部放到join的on中。
SELECT TBL_SchemaDetail.MaterialNo, TBL_StockMaterial.SalePrice FROM TBL_StockMaterial RIGHT OUTER JOIN TBL_SchemaDetail ON TBL_StockMaterial.MaterialNo = TBL_SchemaDetail.MaterialNo WHERE (TBL_SchemaDetail.SchemaNo = '7411') AND (TBL_StockMaterial.SalePrice = 0)
连接和条件分开。
