construct that stores historical data and keeps versions of the data in the same table. Chapter 1 You can execute the SQL as it is generated, you can modify it before executing it (as you did in the recipe), or you can just ignore it. Sometimes the SQL generated includes dropping a column just because the column exists in the table but is not used in the transformation. In that case you shouldn't execute it. Read the generated statement carefully, before executing it. Finally, you must know

thinking of a MongoDB document is that they are akin to a multidimensional array. Like many NoSQL databases, the schema structure is dynamic. This means that the descriptors of a dataset can be added, removed, or not even required for records to be stored into a given document. Getting ready We will continue to use the Lahman's Baseball Database mentioned earlier in the chapter to load MongoDB and later use it to query for specific data. Before we can do anything else though, we need to make

the metadata generated by those predefined statements can make your transformation crash. You can also use the same variable more than once in the same statement. This is an advantage of using variables as an alternative to question marks when you need to execute parameterized SELECT statements. Named parameters are another option to store parts of statements. They are part of the job or transformation and allow for default values and clear definitions for what the parameter is. To add or edit
