java - How to disable other operations without querying with jdbcTemplate - query method -


i found while using query method jdbctemplate sql statement "delete table_name..." or "alter table table_name...", etc.
, sql or command executed though oracle error code exception thrown out. want query db not change it, how disable/restrict other invalid operations without querying?

the sample code shown follows:

  ...   jdbctemplate targetjt = new jdbctemplate();      targetjt.setdatasource(tx.getdatasource());    string sql = "alter table hr add ch_name varchar2(16)";     targetjt.queryforlist(sql);   ...

then program receive ora-01003: no statement parsed, column ch_name created.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
