#静态游标指的是程序执行的时候不需要再去解析sql语言, the parsing of SQL statements can be done at compile time.Because the dynamic cursor contains parameters, parsing of the SQL statements must wait until the parameters are determined to complete.From this point of view,

First of all, we need to rearrange the relevant concepts, functions in an Oracle database are invoked only by others, stored procedures can be executed separately, and a stored procedure can be invoked, and the package's action package can place any

First, you need to repeat the related concepts. Functions in oracle databases can only be called by others. stored procedures can be executed separately and stored procedures can be called, First, you need to repeat the related concepts. Functions

Although PL/SQL is used in the next project, it is unclear what specific points of knowledge need to be used. It is important to estimate the cursor, and if it can be changed on the basis of existing code to meet the requirements of the project, now

1.%type allows users to dynamically associate the data type of a column in a database with a variable in PL/SQL. The syntax is as follows: Variable_name Table.column%type 2.%rowtype allows a user to define a single variable that contains

1. Create an Oracle package definition. Use the ref cursor data type to process the Oracle result set. Ref cursor is a pointer to the result set returned by PL/SQL queries. Unlike a normal CURSOR, ref cursor is a variable that references the CURSOR.
