Public Function CheckMyQuantity() As DataSet
Dim sqlString As String

Dim adapter As OleDbDataAdapter

Dim leongy As DataSet

'these 2 lines
sqlString = "SELECT StockID,StockName,Quantity from Branch2Stock WHERE Quantity > 100"
sqlString = "SELECT StockID,StockName,Quantity from BranchStock WHERE Quantity < 20"




adapter = New OleDbDataAdapter(sqlString, cn)

leongy =
New DataSet

Ive assumed that the stockid in each table corresponds to the same stock item

SELECT Branch2Stock.StockID AS Branch2Stock_StockID, Branch2Stock.StockName AS Branch2Stock_StockName, Branch2Stock.Quantity AS Branch2Stock_Quantity, BranchStock.StockID AS BranchStock_StockID, BranchStock.StockName AS BranchStock_StockName, BranchStock.Quantity AS BranchStock_Quantity
FROM Branch2Stock INNER JOIN BranchStock ON Branch2Stock.StockID = BranchStock.StockID
WHERE (((Branch2Stock.Quantity)>100) AND ((BranchStock.Quantity)<20));
