Running SQL from within a stored procedure
You can run SQL within a native stored procedure (NSP) body that contains SQL parameters and SQL variables. You’ll be prompted to specify values for them before the SQL executes. Note that built-in data types for each input variable are detected automatically and are set to the correct data type.
Important: Make sure you follow the best practices for coding column names and variable names in your SQL statements. See Column names being interpreted as variables for more information.
Note that this feature applies to .spsql files only.
