Fromat datagridview cells based on SQL logic - sql

Question

I have the following SQL statement that checks for duplicate date ranges within my data set.
SELECT *
FROM [DaisyServices].[dbo].[DaisyServicesIndigo] i
JOIN [DaisyServices].[dbo].[DaisyServicesIndigo] i2
on i.cli = i2.cli
and i.quantity = i2.quantity
and i.unitcost = i2.unitcost
and i.totalcost = i2.totalcost
and i.[description] = i2.[description]
and ((i.FromDate <= i2.ToDate) and (i.ToDate >= i2.FromDate))
WHERE i.id<>i2.id
AND (i2.[bill]=0 AND i2.[Billed Month] is Null AND i2.currentbill = 0)
I would like to use this SQL logic, to check each line of my data grid view and then format each line accordingly if the condition is met. i.e. the data ranges overlap.
Something like this, I am just not sure how to incorporate the SQL element?
For Each row As DataGridViewRow In DaisyServicesForm.DataGridView2.Rows
If "SQL condition for the specific line is true" Then
row.DefaultCellStyle.ForeColor = Color.Blue
End If
Next
Any help greatly appreciated.

Answer 1

Try this piece of code
For intcount=0 to DaisyServicesForm.DataGridView2.Rows.count-1
If checkdata(intcount)=true Then
datagridview2.rows(intcount).DefaultCellStyle.ForeColor = Color.Blue
End If
Next
and add a checking function in your code like:
Private Function checkdata(ByVal row As Integer) As Boolean
Dim da As SqlDataReader
Dim command As SqlCommand
command.CommandType = CommandType.Text
command.Connection = connection
command.CommandText = "Your query for checking if the item in specified row is in database"
da = command.ExecuteReader
If da.HasRows Then
Return True
Else
Return False
End If
End Function
specify the checking in the command text in fucntion.Just Provided this as an example,you may modify it upon our own needs.
