I need to insert the data from an excel sheet into a teradata table. and I need this to be done using a MACRO.
I have data in an excel sheet like
COL1 COL2 COL3 COL4 1 2 3 4 2 5 8 10 . .so on
and i need to keep a button in the excel sheet and assign a macro to that button so that when i click the button the rows in the excel sheet should be inserted into a database table.
The requirement is that I will send the empty excel sheet to the person, he will fill in the sheet with the data and he clicks the button in the excel and the data has to be inserted into the database table. I would prefer doing this using a macro..
Thanks all.
Have a look at this link for using vb/vba code (for the marco) to move data from excel to sql server.
I've created function that will transform the Excel table into multiple Insert Commands.
Copy this into the module and then in formula, set up as first parameter the values of cells that needs to be inserted, the second range should be the names of columns (press F4 to set up this as constant), and third (optional) the name of the table. If table name is not specified, then the name of sheet will be used as default.
In your case this is how the spreadsheet should look like:
+---+------+------+------+------+-----------------------------------------+
| | A | B | C | D | E |
+---+------+------+------+------+-----------------------------------------+
| 1 | COL1 | COL2 | COL3 | COL4 | |
+---+------+------+------+------+-----------------------------------------+
| 2 | 1 | 2 | 3 | 4 | =Insert2DB(A2:D2,$A$1:$D$1,"TableName") |
+---+------+------+------+------+-----------------------------------------+
| 3 | 2 | 5 | 8 | 10 | =Insert2DB(A3:D3,$A$1:$D$1,"TableName") |
+---+------+------+------+------+-----------------------------------------+
This will generate for you those two queries:
INSERT INTO TableName ([COL1],[COL2],[COL3],[COL4]) VALUES (1,2,3,4)
INSERT INTO TableName ([COL1],[COL2],[COL3],[COL4]) VALUES (2,5,8,10)
Here is the function (works good with Microsoft SQL (TSQL):
Function Insert2DB(InputRange As Range, Optional ColumnsNames As Variant, Optional TableName As Variant)
Dim rangeCell As Range
Dim InsertValues As String
Dim CellValue As String
Dim C As Range
Dim AllColls As String
Dim SingleCell As Range
Dim TableColls As String
InsertValues = ""
'Start Loop
For Each rangeCell In InputRange.Cells
'Recognize data type
Set C = rangeCell
If IsEmpty(C) Then
'DataType is NULL then NULL
CellValue = "NULL"
ElseIf Application.IsText(C) Then
'DataType is VARCHAR or CHAR
CellValue = "'" & Trim(rangeCell.Value) & "'"
ElseIf Application.IsLogical(C) Then
'DataType is bit eg. TRUE / FALSE
If rangeCell.Value = True Then
CellValue = "1"
ElseIf rangeCell.Value = False Then
CellValue = "0"
End If
ElseIf Application.IsErr(C) Then
'If there is an ERROR in cell, the statment will return 0
CellValue = "NULL"
ElseIf IsDate(C) Then
'DataType is DATE or DATETIME, in case it is DATE specifying HH:mm:ss would do no harm
CellValue = "'" & VBA.Format(rangeCell.Value, "yyyymmdd hh:mm:ss") & "'"
ElseIf InStr(1, C.Text, ":") <> 0 Then
'DataType is TIME
CellValue = "'" & VBA.Format(rangeCell.Value, "hh:mm:ss") & "'"
ElseIf IsNumeric(C) Then
'DataType is number
CellValue = rangeCell.Value
End If
If (Len(InsertValues) > 0) Then
InsertValues = InsertValues + "," + CellValue
Else
InsertValues = CellValue
End If
Next rangeCell
'END Loop
If IsMissing(ColumnsNames) Then
TableColls = ""
Else
For Each SingleCell In ColumnsNames.Cells
If Len(AllColls) > 0 Then
AllColls = AllColls + "," + "[" + Trim(Replace(SingleCell.Value, Chr(160), "")) + "]"
Else
AllColls = "[" + Trim(Replace(SingleCell.Value, Chr(160), "")) + "]"
End If
Next SingleCell
TableColls = " (" & AllColls & ")"
End If
'If TableName is not set, then take the name of a sheet
If IsMissing(TableName) = True Then
TableName = ActiveSheet.Name
Else
TableName = TableName
End If
'Set the return value
Insert2DB = "INSERT INTO " & TableName & TableColls & " VALUES (" & InsertValues & ")"
End Function
If you have quite a lot data to insert, you might not need to use INSERT INTO in each command, then just use the Insert2DB function in first row (and every 500th) and for the rest use just Insert2DBValues:
+---+------+------+------+------+-----------------------------------------------+
| | A | B | C | D | E |
+---+------+------+------+------+-----------------------------------------------+
| 1 | COL1 | COL2 | COL3 | COL4 | |
+---+------+------+------+------+-----------------------------------------------+
| 2 | 1 | 2 | 3 | 4 | =Insert2DB(B3:E3,$B$2:$E$2,"TableName") |
+---+------+------+------+------+-----------------------------------------------+
| 3 | 2 | 5 | 8 | 10 | =Insert2DBValues(A3:D3,$A$1:$D$1,"TableName") |
+---+------+------+------+------+-----------------------------------------------+
This will give you following commands:
INSERT INTO TableName ([COL1],[COL2],[COL3],[COL4]) VALUES (1,2,3,4)
,(2,5,8,10)
Function Insert2DBValues(InputRange As Range, Optional ColumnsNames As Variant, Optional TableName As Variant)
Dim rangeCell As Range
Dim InsertValues As String
Dim CellValue As String
Dim C As Range
Dim AllColls As String
Dim SingleCell As Range
Dim TableColls As String
InsertValues = ""
'Start Loop
For Each rangeCell In InputRange.Cells
'Recognize data type
Set C = rangeCell
If IsEmpty(C) Then
'DataType is NULL then NULL
CellValue = "NULL"
ElseIf Application.IsText(C) Then
'DataType is VARCHAR or CHAR
CellValue = "'" & Trim(rangeCell.Value) & "'"
ElseIf Application.IsLogical(C) Then
'DataType is bit eg. TRUE / FALSE
If rangeCell.Value = True Then
CellValue = "1"
ElseIf rangeCell.Value = False Then
CellValue = "0"
End If
ElseIf Application.IsErr(C) Then
'If there is an ERROR in cell, the statment will return 0
CellValue = "NULL"
ElseIf IsDate(C) Then
'DataType is DATE or DATETIME, in case it is DATE specifying HH:mm:ss would do no harm
CellValue = "'" & VBA.Format(rangeCell.Value, "yyyy-mm-dd hh:mm:ss") & "'"
ElseIf InStr(1, C.Text, ":") <> 0 Then
'DataType is TIME
CellValue = "'" & VBA.Format(rangeCell.Value, "hh:mm:ss") & "'"
ElseIf IsNumeric(C) Then
'DataType is number
CellValue = rangeCell.Value
End If
If (Len(InsertValues) > 0) Then
InsertValues = InsertValues + "," + CellValue
Else
InsertValues = CellValue
End If
Next rangeCell
'END Loop
If IsMissing(ColumnsNames) Then
TableColls = ""
Else
For Each SingleCell In ColumnsNames.Cells
If Len(AllColls) > 0 Then
AllColls = AllColls + "," + "[" + Trim(Replace(SingleCell.Value, Chr(160), "")) + "]"
Else
AllColls = "[" + Trim(Replace(SingleCell.Value, Chr(160), "")) + "]"
End If
Next SingleCell
TableColls = " (" & AllColls & ")"
End If
'If TableName is not set, then take the name of a sheet
If IsMissing(TableName) = True Then
TableName = ActiveSheet.Name
Else
TableName = TableName
End If
'Set the return value
Insert2DBValues = ",(" & InsertValues & ")"
End Function
And finally, if you are using MySQL, there is different escaping of strings, so in such a case use Insert2DBMySQL:
Function Insert2DBMySQL(InputRange As Range, Optional ColumnsNames As Variant, Optional TableName As Variant)
Dim rangeCell As Range
Dim InsertValues As String
Dim CellValue As String
Dim C As Range
Dim AllColls As String
Dim SingleCell As Range
Dim TableColls As String
InsertValues = ""
'Start Loop
For Each rangeCell In InputRange.Cells
'Recognize data type
Set C = rangeCell
If IsEmpty(C) Then
'DataType is NULL then NULL
CellValue = "NULL"
ElseIf Application.IsText(C) Then
'DataType is VARCHAR or CHAR
CellValue = "'" & Trim(rangeCell.Value) & "'"
ElseIf Application.IsLogical(C) Then
'DataType is bit eg. TRUE / FALSE
If rangeCell.Value = True Then
CellValue = "1"
ElseIf rangeCell.Value = False Then
CellValue = "0"
End If
ElseIf Application.IsErr(C) Then
'If there is an ERROR in cell, the statment will return 0
CellValue = "NULL"
ElseIf IsDate(C) Then
'DataType is DATE or DATETIME, in case it is DATE specifying HH:mm:ss would do no harm
CellValue = "'" & VBA.Format(rangeCell.Value, "yyyy-mm-dd hh:mm:ss") & "'"
ElseIf InStr(1, C.Text, ":") <> 0 Then
'DataType is TIME
CellValue = "'" & VBA.Format(rangeCell.Value, "hh:mm:ss") & "'"
ElseIf IsNumeric(C) Then
'DataType is number
CellValue = rangeCell.Value
End If
If (Len(InsertValues) > 0) Then
InsertValues = InsertValues + "," + CellValue
Else
InsertValues = CellValue
End If
Next rangeCell
'END Loop
If IsMissing(ColumnsNames) Then
TableColls = ""
Else
For Each SingleCell In ColumnsNames.Cells
If Len(AllColls) > 0 Then
AllColls = AllColls + "," + "" + Trim(Replace(SingleCell.Value, Chr(160), "")) + ""
Else
AllColls = "" + Trim(Replace(SingleCell.Value, Chr(160), "")) + ""
End If
Next SingleCell
TableColls = " (" & AllColls & ")"
End If
'If TableName is not set, then take the name of a sheet
If IsMissing(TableName) = True Then
TableName = ActiveSheet.Name
Else
TableName = TableName
End If
'Set the return value
Insert2DBMySQL = "INSERT INTO " & TableName & TableColls & " VALUES (" & InsertValues & ");"
End Function
