In the design of database applications, we often need to obtain the total number of records in some tables to determine whether the total number of records in the table is too large and whether data needs to be backed up. Our common practice is: select count (*) as c from tableA. However, for tables with a large number of records, the above practice will be very time-consuming. In a test on a DELL 4400

When we want to count the total number of records in a datasheet, we use the T-SQL function count (*). If this function is executed in a large table containing millions of rows, it can take a long time to return the total number of records in the entire table, which results in a decrease in query performance. First, the general approach: using the count () function Each database administrator knows how to
