It's important to create the memory-optimized table at deployment time, not at runtime, to avoid the compilation overhead that comes with table creation. In your T-SQL, replace all mentions of ##tempGlobalB with
To accomplish the same result at the query level, add the OPTIMIZE FOR UNKNOWN query hint. The OPTIMIZE FOR UNKNOWN hint doesn't disable the parameter sniffing mechanism, but effectively bypasses it to achieve the same intended result.Starting with SQL Server 2016 (13.x) Service Pack 1, a ...
The bcp utility can be used to import large numbers of new rows into SQL Server tables or to export data out of tables into data files. Except when used with the queryout option, the utility requires no knowledge of Transact-SQL. To import data into a table, you must either use a form...
If a temporary table is created with a named constraint and the temporary table is created within the scope of a user-defined transaction, only one user at a time can execute the statement that creates the temp table. For example, if a stored procedure creates a temporary table with a name...

To begin with, let’s check the contents of the TEMP table, as shown in Figure 4-5. Figure 4-5. Checking the baseline data Notice in Figure 4-5 that we’ve currently got two rows in the TEMP table. A successful run of the stored procedure would result in an additional two rows in...
