Just as with temp and regular tables, users can perform all Data Modification Language (DML) queries against a table variable: SELECT, INSERT, UPDATE, and DELETE. Usage Temp Table vs Table Variable Temporary tables are usually preferred over table variables for a few important reasons: ...
Table variables are great for small result sets, since they avoid these recompilations, and also because they do not have statistics that SQL Server has to maintain. But the latter point is a double-edged sword: the more rows in the table variable, the worse decisions the optimizer may make...

Temp tables may be a better solution in this case. For queries that join the table variable with other tables, use the RECOMPILE hint, which causes the optimizer to use the correct cardinality for the table variable. table variables aren't supported in the SQL Server optimizer's cost-based...

. Local temporary tables are deleted after the user disconnects from the instance of SQL Server. Global temporary tables are visible to any user and any connection after they are created, and are deleted when all users that are referencing the table disconnect from the instance of SQL Server....
