DB2 bind is process that prepares an access path to the data. This access path is stored as a package in the DB2 catalogue.
In the context of IBM Db2, “bind” refers to the process of associating a SQL statement or a set of SQL statements with the underlying database objects and creating an access plan. The access plan is a set of instructions that the Db2 database uses to execute the SQL statements efficiently.
During the bind process, Db2 takes the SQL statements and creates an access plan based on the database schema, statistics, and other factors. This access plan is then stored in the database catalog for later use. The goal of the bind process is to optimize the execution of SQL statements and improve overall performance.
In summary, DB2 bind is a crucial step in the preparation and optimization of SQL statements for execution within the Db2 database environment. It helps in creating efficient access plans for the SQL statements, contributing to better performance of database queries and transactions.
