| 00:22 | Removed the direct btree tests - part of the ongoing effort to test by calling only public interfaces. Modify the sqlite3VdbeRecordCompare interface to used a pre-parsed second key - resulting in a 13% performance improvement on speed1p.test. (CVS 4911) (check-in: 0e1d84f2f4 user: drh tags: trunk) | |

** CAPI3REF: Open A BLOB For Incremental I/O {F17810}
**
** This interfaces opens a handle to the blob located
** in row iRow, column zColumn, table zTable in database zDb;
** in other words, the same blob that would be selected by:
**
** <pre>
** SELECT zColumn FROM zDb.zTable WHERE rowid = iRow;
** </pre> {END}
**
** If the flags parameter is non-zero, the blob is opened for
** read and write access. If it is zero, the blob is opened for read
** access.
**
** Note that the database name is not the filename that contains
** the database but rather the symbolic name of the database that
** is assigned when the database is connected using [ATTACH].
** For the main database file, the database name is "main". For
** TEMP tables, the database name is "temp".
**
** On success, [SQLITE_OK] is returned and the new
** [sqlite3_blob | blob handle] is written to *ppBlob.
** Otherwise an error code is returned and
** any value written to *ppBlob should not be used by the caller.
** This function sets the database-handle error code and message
** accessible via [sqlite3_errcode()] and [sqlite3_errmsg()].
