Table variables and temporary tables are two options. I remember seeing a large number of temporary data set processing requ

Temporary tables, table variables, and CTE are commonly used in SQL Server to store temporary table data, and here is a brief introduction to the different and different scenarios in which they are used.CteA CTE is often called a "generic expression" and is created in memory.Purpose: Typically used to replace subqueries that require recursion.Valid range: CTE can

Start A while ago, a project encountered such an SQL query requirement. There were two tables with the same structure (table_left table_right), as shown below: Figure 1. Check whether there is a group of (groupId) data in table table_right that is exactly the same as its data. 1. We can see that the table_left and table_right tables have two groups of data that
