Richard Hipp and others, that implements an embeddable SQL database engine.

Programs that link with the SQLite library can have SQL database access without running a separate RDBMS process.

The distribution comes with a standalone command-line access program (sqlite) that can be used to administer an SQLite database and which serves as an example of how to use the SQLite library.

SQLite is not a client library used to connect to a big database server.

The SQLite library reads and writes directly to and from the database files on disk.

This build of sqlite uses the GNU readline library, which provides fancy command-line editing (using, e.g.

Emacs key bindings) as well as a command history.

Software built using the included libsqlite.a library does not link with readline and thus is not tainted by the GPL.

For example, to query cached data from the Sheet table, execute SELECT FROM SheetCache.

DELETEUPDATEINSERT statements is not allowed and will throw an exception.

It can be used both with Auto Cache and with Cached Data Only Offline Mode.

To always use IMEX1 is a safer way to retrieve data for mixed data columns.

Excel Database Engine Driver To Guess

Consider the scenario that one Excel file might work fine cause that files data causes the driver to guess one data type while another file, containing other data, causes the driver to guess another data type.

I e the structure is similar but its not saved in a text readable format as the Xlsx files and can improve performance if the file contains a lot of data.

HDRYes; indicates that the first row contains columnnames, not data.

Some reports that Excel 2003 need the exta OLEDB; section in the beginning of the string.

IMEX1; tells the driver to always read intermixed (numbers, dates, strings etc) data columns as text.

Note that this option might affect excel sheet write access negative.

SQL syntax SELECT Column Name One, Column Name Two FROM Sheet One.

I.e. excel worksheet name followed by a and wrapped in brackets.

SELECT FROM Sheet1a5:d, start picking the data as of row 5 and up to column D.

Check out the HKEYLOCALMACHINESOFTWAREMicrosoftJet4.0EnginesExcel located registry REGDWORD TypeGuessRows.

Thats the key to not letting Excel use only the first 8 rows to guess the columns data type.

Please also note that adding the IMEX1 option might cause the IMEX feature to set in after just 8 rows.

Use IMEX0 instead to be sure to force the registry TypeGuessRows0 (scan all rows) to work.

Excel Database Engine Password With Your

If the Excel workbook is protected by a password, you cannot open it for data access, even by supplying the correct password with your connection string.

If you try, you receive the following error message: Could not decrypt file.
