When trying to use the "Import MySQL data", the function sometimes crashes with an alert "Error copying table data" with the below details:
Exception thrown by:
MySqlDataTable.CopyTableData
Stack trace:
à System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
à System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
à System.String.System.IConvertible.ToInt32(IFormatProvider provider)
à System.Data.Common.Int32Storage.Set(Int32 record, Object value)
à System.Data.DataColumn.set_Item(Int32 record, Object value)
This seems to be caused by the script switching column order while trying to import the table, if columns have a different type and are not created in the alphabetical order. This can be reproduced by creating a test database (below) and trying to import it into Excel.
How to repeat:
