Original: PL/SQL Developer how to connect a 64-bit Oracle plotDue to the continuous updating of hardware technology, Win7 system gradually become mainstream, and computer memory gradually increased, in order to make full use of memory resources (because 32 of the system can only use up to 3G of memory), improve system performance, many people began to use the Win7 (64Bit) system. A 64-bit Oracle database is

I have been working on Oracle databases for more than a year. My favorite part is PL/SQL. This is Oracle's data programmable language, which can be used to combine procedural code with SQL code. The most interesting thing is that we can use it to develop the entire application in one place. All data selection and updates, all HTTP and HTML outputs that interact w

PL/SQL Developer connects to the Oracle (64Bit) diagram installed on Windows 7. Thanks to the continuous update of hardware technology, Windows 7 has gradually become the mainstream and the computer memory has gradually increased, to make full use of memory resources (because 32 is the system can only use about 3 GB of memory) and improve system performance, many people begin to use Win7 (64Bit) systems.

I. Case Study A database has two tables about employee information, salary, and department information of a company. They are EMP and dept tables. The structure of the two tables is as follows: The requirements are as follows: 1. Create a corresponding table according to the structure of the table above, and write 5 combination data into each table. 2. The related table is manipulated to increase the salaries of employees in the "Technical Department" by 20%. 3. Create logs to track salary chang

If an online e-commerce system, we now need to be based on the order form reflected in the consumption of the customer simply divided into three categories of large and small and inserted into three tables. Order Form orders (order_id number, cust_id number, amount number); Small Customer table Small_cust (cust_id number, tot_amt number); Customer table Med_cust (cust_id number, tot_amt number); Large Customer table Big_cust (cust_id number, tot_amt number); If the total consumption amount

Tags: style blog http color io using Java ar StrongSometimes we need to do some slightly more complex operations on the data in the database, and these operations are all one-time and are no longer used after they are exhausted.It is too cumbersome and wasteful to use stored procedures, and to be deleted when it is exhausted. and a single SQL cannot meet the requirements. This is the time to use the SQL sta

Win7 has gradually become the mainstream Windows operating system, and its 32-bit and 64-bit systems are equally different. However, no 64-bit PL/SQL developer is available yet. When 32-bit PL/SQL developer is directly used to connect win7 (64-bit) as the server's oracle, such errors always occur. You can find a method

1. PL/SQL recordsIntroduction: similar to the structure in advanced languages, you can use custom record types, record variables, and % rowtype to define record variables for processing a single row of data. Benefit: You can regard this record set as a class and then define multiple objects of this class. The fields in this class are the fields required for user filtering. then you can directly access these

Pl/sql handles exceptions differently from other programming languages, the PL/SQL exception handling mechanism is similar to Ada, with a full inclusion method for handling errors. When an error occurs, the program unconditionally transfers to the exception-handling section, which requires the code to be very clean and
