statements. So I asked someone else if I could use a Combined Query method to pass Parameters. As a result, I used a stored procedure. I thought: Why not?
Next we will look at the specific implementation code of this method by querying the combined query function of user work logs:
First, we need to define an entity class for Combined Query at the Entity layer entity:
Public Class QueryWorklog Private

Today, a friend from a project team asked: how to call the stored procedure of Oracle in. NET and input it as an array.
Oracle's PL/SQL statements are very powerful. They support fixed-length arrays and variable-length arrays, and support any custom data types. By reading the ODP documentation, we found that Oracle fully supports using arrays as stored procedure paramet

In Oracle, compare the data in a table with the input parameters and perform corresponding operations (stored procedures). If table a contains y records greater than x, insert y A words to Table.
