In some scenarios, developers want to be able to import entity data into a database in large quantities. Although it is convenient to use entity repositories to save the list of entities, the internal implementation mechanism is one-to-one saving to the database, and when the number of entities is large, the efficiency is very low. So Rafy designed a bulk import plug-in program, which uses the bulk import m

We know that there is an overhead for running SQL statements in PL/SQL programs, because SQL statements must be submitted to the SQL engine for processing. The transfer of control between PL/SQL engine and SQL engine is called context change, but each change has additional overhead. See: However, forall and bulk collect allow the PL/SQL engine to compress multiple contexts into one, this causes the time required to execute the SQL statement to proce

SQL Server's BULK INSERT statement can import local or remote data files into a database in batches, very quickly. The remote file must be shared before the file path should use the Universal Convention (UNC) name, which is the form of "\ \ server name or ip\ share name \ path \ file name."* 1. Because BULK insert is often more convenient to bulk import data with

9.4 Batch processing data Typically, only a limited number of persisted objects are stored in the cache of a Session object, and the session object is closed when the session object processes the transaction, releasing the memory occupied by the session's cache in a timely manner. Bulk processing data refers to handling large amounts of data in a transaction. The following program batch updates the age field for all records in a Customers table that

In the process of database initialization, a real problem that administrators need to face is how to import large capacity data into the database system. A number of large-capacity data import and export tools are available in the SQL Server database for database administrators to be useful. Administrators can implement bulk export data and bulk import data and generate format files through the bcp utility.

From a technical point of view, there is no essential difference between bulk and boxed CPUs, at least in terms of quality. Theoretically, there is no gap in performance, stability, and overclocking potential between boxed and bulk products, but there are certain differences in warranty. The difference between bulk and boxed from a technical point of view, there

GUIDs are bound to be faster than self-growth, because you will have less time to generate a GUID algorithm than to re-query the ID value of the previous record from the data table and then add the 1 operation.

The Bulk Collect feature is introduced in Oracle8i for the first time. This feature allows you to use batch queries in PL/SQL. Batch queries can significantly improve query efficiency in some cases.

In this article, I'll explain a lot about inserting data in SQL Server in the future. To create a database and table to test, the primary key in the table is a GUID, and no indexes are created in the table in order for the data to be inserted faster. GUIDs are bound to be faster than self growth, because the time you take to generate a GUID algorithm is certainly less than the number of times you requery the ID of the previous record from the datasheet and then add a 1 operation.
