SQL查詢功能獲得最匹配的參數

Question

我使用的是SQL實現搜索，這是查詢

Select CM.ID, ProductName,ImageURL,SKU,AA.Name as 
MemberName,Price,Discount,DM.Name as CategoryName from tblMasterProduct CM 
INNER JOIN tblProducts OM ON CM.ID=OM.MasterProductID 
INNER JOIN tblMasterCategory DM ON CM.SubCategoryID=DM.ID 
INNER JOIN tblOnlineRetailMember AA ON OM.MemberID=AA.ID 
WHERE 1=1 AND CM.ProductName LIKE '% watches %' AND CM.SubCategoryID= 112 
AND (OM.Price - OM.Discount) BETWEEN 0 And 200000 

的問題是，包含該單詞的手錶，而我也該查詢返回結果喜歡獲取包含「Watch」一詞的所有條目。

編輯：對不完整的信息抱歉，查詢是寫入存儲過程和字符串由用戶輸入，無法從用戶獲得「觀察」。

Answer 1

嘗試使用SOUNDEX或DIFFERENCE功能MSSQL。如果ProductName是一個多話，那麼你可以使用PARSENAME拆分單詞並使用差異找到字符串中的一個類似的一句話：

select * from t WHERE DIFFERENCE(ProductName,'watches')>=3

當您查詢

Answer 2

您可以使用OR ..

Select CM.ID, ProductName,ImageURL,SKU,AA.Name as 
MemberName,Price,Discount,DM.Name as CategoryName from tblMasterProduct CM 
INNER JOIN tblProducts OM ON CM.ID=OM.MasterProductID 
INNER JOIN tblMasterCategory DM ON CM.SubCategoryID=DM.ID 
INNER JOIN tblOnlineRetailMember AA ON OM.MemberID=AA.ID 
WHERE 1=1 AND (CM.ProductName LIKE '%watches%' or CM.ProductName LIKE '%watch%' ) AND CM.SubCategoryID= 112 
AND (OM.Price - OM.Discount) BETWEEN 0 And 200000 

Answer 3

可以通過OR實現它。

查詢

Select CM.ID, ProductName,ImageURL,SKU,AA.Name as MemberName, 
Price,Discount,DM.Name as CategoryName from tblMasterProduct CM 
INNER JOIN tblProducts OM ON CM.ID=OM.MasterProductID 
INNER JOIN tblMasterCategory DM ON CM.SubCategoryID=DM.ID 
INNER JOIN tblOnlineRetailMember AA ON OM.MemberID=AA.ID 
WHERE 1=1 AND (CM.ProductName LIKE '%watches%' OR CM.ProductName LIKE '%watch%') 
AND CM.SubCategoryID= 112 
AND (OM.Price - OM.Discount) BETWEEN 0 And 200000; 

Answer 4

如果您正在尋找動態查詢，這個工程

Select CM.ID, ProductName,ImageURL,SKU,AA.Name as MemberName, 
Price,Discount,DM.Name as CategoryName from tblMasterProduct CM 
INNER JOIN tblProducts OM ON CM.ID=OM.MasterProductID 
INNER JOIN tblMasterCategory DM ON CM.SubCategoryID=DM.ID 
INNER JOIN tblOnlineRetailMember AA ON OM.MemberID=AA.ID 
WHERE 1=1 AND (CM.ProductName LIKE '%watches %' 
OR CHARINDEX(LEFT('watches',len('watches')-1) ,CM.ProductName) > 0 --watche 
OR CHARINDEX(LEFT('watches',len('watches')-2) ,CM.ProductName) > 0 --watch 
) 
AND CM.SubCategoryID= 112 
AND (OM.Price - OM.Discount) BETWEEN 0 And 200000;
