variables: 1. p_table 2. p_constraint_name 3. p_schema The first two are easy to find, but why is there p_schema? Because the current USER name may also be a dangerous string constructed by the USER. Well, according to the general rule, we should follow the order below: 1. Static SQL. Do not use variables. 2. Bind the variable. Similar to the PreparedStatement in Java, data is stored in variables instead o

No matter how fast the network, as long as the client and the server to do a large amount of data exchange, the efficiency of the application run back to be affected.
