What is the method in T-SQL for combining two concrete tables?

edit

The method in T-SQL for combining two concrete tables is to use the JOIN operator. There are several types of JOINs including INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN, which allow you to combine two tables based on matching or non-matching values in specific columns. Here is an example of an INNER JOIN:

SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column;

This SQL statement will combine table1 and table2 based on matching values in the specified column. The resulting table will include all columns from both tables where there is a match in the specified column.
