immediate) DML statement. 2. Use of FORALL The table structure used in the example is as follows: Tmp_tab (2 id NUMBER (5), 3 name VARCHAR2 (50) 4 ); Example 1: Use FORALL to insert, modify, and delete data in batches: TYPE tb_table_type tmp_tab % rowtype index by BINARY_INTEGER; 5 tb_table tb_table_type; I IN 1 .. 100 LOOP 8tb_table (I ). id: = I; 10 END LOOP ;

The following articles mainly introduce how to bind 10 Gb of Oracle to forall bulk collect in batches, we all know that batch binding generally reduces context switches between PL/SQL and SQL engines to improve performance. Bulk binds can be bound in batches: (1) Input collections, use the FORALL statement to Improve the Performance of DMLINSERT, UPDATE, and DELE

Label:How to use ForAll and bulk collect:1. Using ForAll is more efficient than for, because the former switches only once to the context, while the latter switches between multiple contexts in the same number of cycles.2. Using Bluk collect to fetch a data collection at once is more efficient than using a cursor bar, especially if the network is not very good. But Bluk collect requires a lot of memory.Exam

FORALL and bulk collect statements for Oracle databases Let's take a look at the execution process of PL/SQL blocks: When the PL/SQL runtime engine processes a piece of code, it uses the PL/SQL engine to execute Procedural Code, the SQL statement is sent to the SQL engine for execution. After the SQL engine completes execution, the result is returned to the PL/SQL engine. This kind of interaction between P
