How to Retrieve Yesterday's Records Using SQL?

Retrieving Yesterday's Data with SQL: A Step-by-Step Guide

This guide demonstrates how to construct an SQL query to efficiently select all entries from a table that were created on the previous day. We'll focus on a table with a datetime column, specifically within the context of SQL Server 2005.

Extracting Yesterday's Date (Without Time)

The key is to isolate the date portion, excluding the time component. This query achieves that for yesterday:

SELECT DATEADD(day, DATEDIFF(day, 1, GETDATE()), 0)

Constructing the Full Query

To retrieve all records from your table (yourTable) for yesterday, use this query:

SELECT *
FROM yourTable
WHERE YourDate >= DATEADD(day, DATEDIFF(day, 1, GETDATE()), 0)
  AND YourDate < DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0);

This query efficiently filters your data by comparing the YourDate column to the beginning and end of yesterday's date range. This ensures you only select data from the previous day. Replace yourTable and YourDate with your actual table and column names.

This approach provides a robust and accurate method for retrieving yesterday's records, simplifying the process of temporal data extraction.
