Connecting PL/SQL to oracle database and plsqloracle DatabaseConnecting PL/SQL to oracle database 1. Introduction Use pl/SQL to connect to a remote oracle database without installing the oracle database. 2. steps: A) install PL/SQL and the oracle client based on your operating system (it has nothing to do with the ver

PL/SQL Exception error handling A good program should be able to correctly handle all kinds of errors and recover from errors as much as possible. Oracle provides EXCEPTION and exception handler for error handling. -------------------------------------- Split line -------------------------------------- Rlwrap SQLPLUS spool to dynamic Log File Name Oracle SQLPLUS prompt settings Accelerate SQL return by setting SQLPLUS ARRAYSIZE (row prefetch)

The flow control statements in the PL/SQL program draw on the process control ideas of many high-level languages, but have their own characteristics. Condition control The following example describes the use of conditional control statements. 1. If.. Then.. End If condition control Use If.. Then.. The End If condition controls the syntax structure as shown in Figure 9.15. Execute the following pl/sql pro

PL/SQL Developer is an integrated development environment that specializes in developing applications for Oracle databases. PL/SQL is also a programming language called the procedural SQL language (procedural language/sql). PL/SQL is an extension of the Oracle database to the statement. In the use of ordinary SQL statements to add the characteristics of the progr

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 with LDAP, and everything else can be done in one language. However, the disadvantage is th

In general PL/SQL programming, SQL can be directly used in DML and transaction control statements, but DDL statements and system control statements cannot be directly used in PL/SQL, to use DDL statements and system control statements in PL/SQL, you can use dynamic SQL. First, we should know what dynamic SQL is. in Oracle Database Development,

The purpose of this article is to use block memory for PS and PL data interaction or data sharing, through the ZYNQ PS end of the master GP0 port to write data to Bram, and then through the PS end of the Mater GP1 the data read out, the results printed output to the serial terminal display. Involves the use of Axi BRAM Controller and IP such as Block memery generator. This series of articles as far as possible to make each experiment is relatively in

Today encountered an error prompt: ORA-06502: PL/SQL: numberic or value error: character string buffer too small, the general corresponding Chinese information is: ORA-06502: PL/SQL: incorrect number or value: the string buffer is too small. During the debugging process, we found that the developer defined a variable, but the variable is assigned a value that exceeds its length in the script. The error is r

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. The 64-bit Oracle database is installed on a 64

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 that can be used normally through online materials and self-testing. 1. Download the

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 fields on the object. syntax: tyep type_reco

PL/SQL provides three common set union arrays, nested tables, and variable-length arrays, PL/SQL provides corresponding functions or procedures for operation. Element or subscript in the vertical array. These functions or procedures are called set methods. A set method is a function or process built into the set and can operate the set. You can use the vertex flag . This document describes how to operate th

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

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 separate the error-handling part from the rest of the program. Oracle allows other except
