# Organization of tests in this file:
|
|
#
|
|
# vtab1-1.*: Error conditions and other issues surrounding creation/connection
|
|
# of a virtual module.
|
|
# vtab1-2.*: Test sqlite3_declare_vtab() and the xConnect/xDisconnect methods.
|
|
# vtab1-3.*: Table scans and WHERE clauses.
|
|
# vtab1-4.*: Table scans and ORDER BY clauses.
|
|
# vtab1-5.*: Test queries that include joins. This brings the
|
|
# sqlite3_index_info.estimatedCost variable into play.
|
|
# vtab1-6.*: Test UPDATE/INSERT/DELETE on vtables.
|
|
# vtab1-7.*: Test sqlite3_last_insert_rowid().
|
|
#
|
|
# This file uses the "echo" module (see src/test8.c). Refer to comments
|
|
# in that file for the special behaviour of the Tcl $echo_module variable.
