MYSQL与内部查询结果加入

-1

下面的查询工作，但它给了我同样的数据多次.... 建议我上悬而未决这个MYSQL与内部查询结果加入

"SELECT 
    cp.projectID,cp.projectName,cp.clientID, 
    pv.vendorID, 
    cv.vendorName, 
    c.clientName, 
    vp.productName, 
    pp.sku 
FROM clientProjects AS cp 
    INNER JOIN clients AS c ON c.clientID = cp.clientID 
    INNER JOIN projectVendors AS pv ON cp.projectID = pv.projectID 
    INNER JOIN clientVendors AS cv ON cv.vendorID = pv.vendorID 
    INNER JOIN projectProducts AS pp ON cp.projectID = pp.projectID 
    INNER JOIN projectMaintenance AS pm ON cp.projectID = pm.projectID 
    INNER JOIN vendorProducts AS vp ON pp.sku = vp.sku 
    INNER JOIN projectFiles AS pf ON cp.projectID = pf.projectID 
WHERE cp.projectName LIKE '".$projectName."' OR c.clientName LIKE '".$projectName."' OR pp.sku LIKE '".$projectName."' OR pm.sku LIKE '".$projectName."' "

使用不同或分组以避免冗余。 – 2015-03-02 09:04:58

尝试DISTINCT：由

SELECT DISTINCT cp.projectID, 
       cp.projectName, 
       cp.clientID, 
       pv.vendorID, 
       cv.vendorName, 
       c.clientName, 
       vp.productName, 
       pp.sku 
FROM clientProjects AS cp 
INNER JOIN clients AS c ON c.clientID = cp.clientID 
INNER JOIN projectVendors AS pv ON cp.projectID = pv.projectID 
INNER JOIN clientVendors AS cv ON cv.vendorID = pv.vendorID 
INNER JOIN projectProducts AS pp ON cp.projectID = pp.projectID 
INNER JOIN projectMaintenance AS pm ON cp.projectID = pm.projectID 
INNER JOIN vendorProducts AS vp ON pp.sku = vp.sku 
INNER JOIN projectFiles AS pf ON cp.projectID = pf.projectID 
WHERE cp.projectName LIKE '".$projectName."' OR 
     c.clientName LIKE '".$projectName."' OR 
     pp.sku LIKE '".$projectName."' OR 
     pm.sku LIKE '".$projectName."' "
