# 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 |
