Description
| Opens an ADODB recordset using the specified VIEW, TABLE or SELECT query.
This does not require an ADODB.Connection or even an initialization of the recordset object first. If Records refers to an opened recordset, it will first be closed and the object reinitialized.
Parameter

| Location
| Optional. The method of server access for this record set, see below: CursorLocationEnum.
| CacheSize
| Optional. The record buffer of the opened record set, set to 50 by default.
| TimeOut
| Optional. Specifies the maximum wait time in seconds for the query. If the result does not appear within the specified time, the query is aborted and an error message is generated. Default value: 120 seconds.

*) In addition to opening SQL tables, queries and views, it is also possible to open Microsoft Excel files (.xls, .xlsx) as tables using this method. Thereby it can be optionally specified which worksheet should be read from the Excel file. By default, "Sheet1" is read out.
The same applies to comma-separated text files (.asc, .csv, .tab, .txt). Here you can optionally specify whether the first line contains the field names. By default, the first line is considered the field name definition.
The pararameter then refers to the file name, including path. To set the worksheet, or field names option, two colons should be specified directly after the file name, followed by the option. Some examples:
"c:\mijn documenten\lijst.xls::Blad2"
"c:\mijn documenten\kvklijst.csv"
"c:\mijn documenten\prijzen.txt::NO"
