SQL Queries and Their Execution (Row Mode & Batch Mode)
In this SQL server tutorial we'll walk you through a couple of SQL server SQL query execution modes.
Watch this sql tutorial and you will know that in SQL Server, SQL queries can be executed in two modes:
1) SQL queries can be executed in a row mode
2) SQL queries can be executed in a batch mode
This SQL Server tutorial will tell you that row mode SQL query execution is used when data is stored in a row format. When a SQL query is executed, rows are read one-by-one from applicable database columns.
This SQL Server tutorial will also tell you that during the batch mode of SQL query execution, your database aims to enhance the performance of analytical SQL queries. It's designed to work with columnstore data.
Batch processing also improves the performance of SQL queries without a columnstore index.
This mode was introduced in SQL Server 2012.
Enabling batch processing will, in many cases, drastically improve the performance of analytical SQL queries that deal with grouping and aggregation on big data sets.
Batch mode SQL query processing improves SQL query performance by taking advantage of CPU capabilities.
SQL Server query execution modes can come up in your next sql interview as part of sql interview questions and answers, so make sure to keep an eye out on them!
