||
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; |
||
