select db_a.tbl_b.col_c from db_a.tbl_b

Testcase Code

public void testRenameTable() {

    String sql = "select db_a.tbl_b.col_c from db_a.tbl_b";

    System.out.println("out: "+ out);
}

No response

Error Info

改写表名tbl_b为xxx，在select item中的表名未被正确改写。

input: select db_a.tbl_b.col_c from db_a.tbl_b
out: SELECT db_a.tbl_b.col_c FROM db_a.xxx

补充

另一个case，当select的查询列中使用 'user_extra.col+1 '表名无法被正确替换

select user_extra.col+1 from user_extra
