| * **dBExecuteStatement(Statement):** executes the SQL that it's contain in the parameter (statement). Allows the user to modify the data in the destination database. This function allows you to write SQL statements like Insert, Delete, Update and Merge in the statement parameter. The function will replace the variables for their values in the execution time, that will return a TastInteger with the number of rows that were changed. (Input parameter: The sentence for example:” INSERT INTO x (a, b, c) VALUES (d, e, f)” Output parameter: Integer with the results). | * **dBExecuteStatement(Statement):** executes the SQL that it's contain in the parameter (statement).

Returns an integer with the total number of executed statements. |
| * **dBGetQueryData(Query):** executes the SQL Select statement contained in the Query parameter, and returns the results as a TastTableData variable to the executor, which allows access and work with the data in later steps of the diagram. The Query parameter contains the Select statement to execute in the database. It is possible to use variables created in the diagram within the Query parameter, the function will substitute the variables for their values at run time.(Input parameter (Query), Output parameter (OutputTable)). | * **dBGetQueryData(Query):** executes the SQL Select statement contained in the Query parameter, and returns the results as a TastTableData variable to the executor, which allows access and work with the data in later steps of the diagram.

| * **getNumRows():** returns the number of rows contained in the TastTableData that was generated by the execution of the dBGetQueryData function. It requires the execution of the dBGetQueryData function in previous steps of the diagram. (Don’t need an input parameter, so it’s a function that just return the number of rows of the selected table (with TastTableData)). | * **getNumRows():** returns the number of rows contained in the TastTableData that was generated by the execution of the dBGetQueryData function.
