Updating one table from another sql server

Without these statistics, or with outdated statistics, the query will be slow, as the query optimizer uses inaccurate statistics to create the query execution plan, which is not the optimal plan to execute the query in this case.

SQL Server usually does its job in keeping these statistics up-to-date.

We always upload the data to a table and then begin the process.

Use the code in Listing 1 to create the Get Nums functions the sample database. This meant that if you wanted indexes in your table variables, your only option was to define those indirectly via inline PRIMARY KEY and UNIQUE constraint definitions.

These statistics provide the query optimizer with the distribution of the columns values in the table and the number of rows, also called the cardinality that will result from the query.
