10/13/20259417Google SheetsAdded
  • Added the IncludePrimaryKey connection property.
10/06/20259410GeneralAdded
  • Support for parsing datetime formats using ".S" and ",S" for milliseconds and nanoseconds.
09/24/20259398Google SheetsAdded
  • Added support in the AddSheet stored procedure for a new input parameter, HeaderNames, supplied as a comma-separated list. HeaderNames supplies names for column headers to be added as the first row in a new sheet. These headers can be used later for inserting or updating data.
09/22/20259396Google SheetsChanged
  • Formerly, if there were two spreadsheets with the same filename under folders with the same name and a user had activated the UseIdAsTableName property, the driver picked only the file with the latest changes, and ignored the other file. Now the names of tables that have duplicate names (in the format <spreadsheetName>_<spreadsheetId>) have an <index> marker appended to the end, and UseIdAsTableName returns all relevant files.
09/12/20259386GeneralAdded
  • Added the IsInsertable, IsUpdateable, and IsDeleteable columns to the sys_tables table.
09/10/20259384GeneralChanged
  • All columns in statically defined Views are now reported as read-only.
09/03/20259377GeneralChanged
  • Corrected the behavior when IN criteria with NULL values are used in the projection part. It now returns NULL instead of 0. For example, "NULL IN (1,2)" returns "NULL".

04/07/20228132Google SheetsAdded
  • Added support for querying Sheets by specifying the SpreadsheetId_SheetId instead of SpreadsheetName_SheetName. Just set the UseIdAsTableName connection property to true and use: SpreadsheetId_SheetId in the queries. For ex: SELECT * FROM 11696gdF5QUL1EnYikYiUeMTHRqA1111KbdYDoINqI_1151117664
01/12/20228047Google SheetsChanged
  • Changed the support for working with a custom Range in Select, Insert and UPDATE operations. Columns will instead be named appropriately based on the range instead of starting at A,B,C, etc. This only impacts tables when the Header connection property is set to false. For example: SELECT * FROM Spreadsheet_Sheet1#C1:F5. The column names will be: C, D, E, F. Previously you would get columns with names starting from A: A,B,C,D.
09/02/20217915GeneralAdded
  • Added support for the STRING_SPLIT table-valued function in the CROSS APPLY clause.
08/07/20217889GeneralChanged
  • Added the KeySeq column to the sys_foreignkeys table.
08/06/20217888GeneralChanged
  • Added the new sys_primarykeys system table.
07/23/20217874GeneralChanged
  • Updated the Literal Function Names for relative date/datetime functions. Previously, relative date/datetime functions resolved to a different value when used in the projection as opposed to the predicate. For example: SELECT LAST_MONTH() AS lm, Col FROM Table WHERE Col > LAST_MONTH(). Formerly, the two LAST_MONTH() methods would resolve to different datetimes. Now, they will match.
  • As a replacement for the previous behavior, the relative date/datetime functions in the criteria may have an 'L' appended to them. For example: WHERE col > L_LAST_MONTH(). This will continue to resolve to the same values that were previously calculated in the criteria. Note that the "L_" prefix will only work in the predicate - it not available for the projection.
06/18/20217839Google SheetsAdded
  • Added support for the GOOGLEJSONBLOB JWT certificate type. This works like the existing GOOGLEJSON certificate type except that the certificate is provided as JSON text instead of as a file path.
04/25/20217785GeneralAdded
  • Added support for handling client side formulas during insert / update. For example: UPDATE Table SET Col1 = CONCAT(Col1, " - ", Col2) WHERE Col2 LIKE 'A%'
04/23/20217783GeneralChanged
  • Updated how display sizes are determined for varchar primary key and foreign key columns so they will match the reported length of the column.
04/16/20217776GeneralAdded
  • Non-conditional updates between two columns is now available to all drivers. For example: UPDATE Table SET Col1=Col2
04/16/20217776GeneralChanged
  • Reduced the length to 255 for varchar primary key and foreign key columns.

Changed
  • Updated index naming convention to avoid duplicates.
04/16/20217776GeneralChanged
  • Updated implicit and metadata caching to improve performance and support for multiple connections. Old metadata caches are not compatible - you need to generate new metadata caches if you are currently using CacheMetadata.
02/02/20217703Google SheetsAdded
  • Added a new view: Folders. It can be used to query the folders contained in a user's Google Drive.
