| 25 # Register the echo module. | |
| 26 # | |
| 27 # This test uses a special feature of the echo module. If the name | |
| 28 # of the virtual table is a prefix of the name of the underlying | |
| 29 # real table (for example if the v-table is "tbl" and the real table | |
| 30 # is "tbl_base"), then the name of the real table is modified | |
| 31 # when an "ALTER TABLE ... RENAME TO" is executed on the v-table. | |
| 32 # For example: | |
| 33 # | |
| 34 # sqlite> CREATE TABLE t1_base(a, b, c); | |
| 35 # sqlite> CREATE VIRTUAL TABLE t1 USING(t1_base); | |
| 36 # sqlite> ALTER TABLE t1 RENAME TO t2; | |
| 37 # sqlite> SELECT tbl_name FROM sqlite_master; | |
| 38 # t2_base | |
