Message
Consider using a table variable instead of a temporary table.
Description
It is recommended to use a table variable instead of a temporary table. Table variables are easier to work with, more secure, and cause fewer recompilations.
Additional information
Table variables are easier to work with, as they behave similarly to regular tables and do not require explicit dropping after use. They are also considered more secure, as their scope is limited to the current session, reducing the risk of conflicts or data leakage. Additionally, using table variables can lead to fewer recompilations compared to temporary tables, resulting in better query performance.
Noncompliant code example
CREATE TABLE #ids (id INT NOT NULL);
