Comma-separated list of file extensions to include into the set of the files modeled as tables.

Data Type

string

Default Value

"CSV,TXT,TAB"

Remarks

Comma-separated list of file extensions to include into the set of the files modeled as tables. For example, IncludeFiles=TXT,TAB. The default is CSV, TAB, and TXT.

A 'NOEXT' value can be specified to include files without an extension.

The following archive types are also supported (only when AggregateFiles is true): ZIP, TAR, and GZ. Files of these types are modeled as an aggregated table. You can use DirectoryRetrievalDepth and IncludeSubdirectories to refine the subset of files in the archive that are included in the aggregate table.

When archive files are found, they will be downloaded to the local machine so the driver can extract and parse the contained files. Note: Files contained within an archive must match an extension listed in IncludeFiles to be included in the set of files modeled as tables.

File masks can be specified using an asterisk (*) to provide enhanced filtering capabilities; e.g. IncludeFiles=2020*.csv,TXT.

Files specified in Schema.ini are honored in addition to the files included by this property.

It is also possible to specify datetime filters. We currently support CreatedDate and ModifiedDate. All extension filters are evaluated in disjunction (using OR operator), and then the resulting filter is evaluated in conjunction (using AND operator) with the datetime filters.

Examples:

IncludeFiles="TXT,CreatedDate<='2020-11-26T07:39:34-05:00'"
IncludeFiles="TXT,ModifiedDate<=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 50, 000)"
IncludeFiles="ModifiedDate>=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 49, 000),ModifiedDate<=CURRENT_TIMESTAMP()"
