What are the main differences between #temp tables and @table variables and which one is preferred?..

Answer / Avni Gupta

{"differences":["Temp tables are created using the # symbol before the table name and persist until they are dropped explicitly or the session ends, while table variables are created using the @ symbol and exist only for the scope of the batch or stored procedure in which they were defined.", "Temp tables can be indexed, sorted and joined with other tables, while table variables cannot have indexes or constraints.", "Data in temp tables is stored in a disk space, whereas data in table variables resides in memory.", "Table variables are faster than temp tables as they reside in the memory, but their size is limited to 784MB by default. Temp tables can handle larger amounts of data but are slower due to disk I/O operations."],"preference":"The preference between temp tables and table variables depends on the specific scenario. If you need a temporary table with indexes or joins, use a temp table. If performance is critical and you're working with small sets of data, use a table variable."}
