- How to create temporary table in oracle stored procedure
- Oracle stored procedures are a programming method in Oracle database that allow users to write code and store it in the database so that it can be used repeatedly when needed. Stored procedures can execute a set of SQL statements or other program code, and can accept input parameters and return output results. In Oracle stored procedures, temporary tables are a very practical function, which can be used to store temporary data sets for subsequent processing. This article will delve into the implementation of temporary tables in Oracle stored procedures. 1. Oracle storage

- Let's talk about the use of commonly used escape characters in Oracle
- In Oracle database, strings are often used to represent some numerical values, text or some code segments. When these strings contain some special characters, these special characters may cause errors or make the string unreadable. In this case, we need to use escape characters in Oracle to convert these special characters into normal characters. The escape character consists of a backslash (\) followed by the character to be escaped, such as single quotation mark ('), double quotation mark ("), backslash (\), etc. The following are some commonly used in Oracle Escape characters:
