# Register the echo module.

|
#
|
|
# This test uses a special feature of the echo module. If the name
|
|
# of the virtual table is a prefix of the name of the underlying
|
|
# real table (for example if the v-table is "tbl" and the real table
|
|
# is "tbl_base"), then the name of the real table is modified
|
|
# when an "ALTER TABLE ... RENAME TO" is executed on the v-table.
|
|
# For example:
|
|
#
|
|
# sqlite> CREATE TABLE t1_base(a, b, c);
|
|
# sqlite> CREATE VIRTUAL TABLE t1 USING(t1_base);
|
|
# sqlite> ALTER TABLE t1 RENAME TO t2;
|
|
# sqlite> SELECT tbl_name FROM sqlite_master;
|
|
# t2_base
|
|
# t2
