AspnetPager is doing well. Use it. Oracle paging stored procedure: Create or replace package JT_P_page isType type_cur is ref cursor; -- defines

Recently, I used Java to verify the information of cells in an Excel table. The data volume is large and the verification rules are complex.ProgramThe efficiency will be very low. Considering that the Oracle stored procedure can be compiled, the data will be put into the cache after each compilation, and the next retrieval will be very fast. I haven't touched any

The following articles mainly describe the experience related to Oracle Stored Procedure writing and Related Optimization Measures. After a long period of development on Oracle stored procedure, we have written some experiences on

Oracle 1. Create an oracle Stored Procedure Create or replace procedure proce_test (paramin in varchar2, paramout out varchar2, paraminout in out varchar2) As Varparam varchar2 (28 ); Begin Varparam: = paramin; Paramout: = varparam | paraminout; End; 2. Test the

Using the cursor is much better than returning array variables in terms of memory consumption and time! Example: Create a package for the databaseCreate or replace package ref_cur_demo is Type RC is ref cursor; Procedure

CURSOR traversal in Oracle stored procedure, call job timed execution1, first use for loopThe For loop is a relatively simple and practical method.First, it will automatically open and close cursors.
