![]() ![]() The root folder for parsing results and other temporary files produced by the import session. The example shows a minimal example where the columns of the CSV file is mapped directly to the table columns. The example shows how data about fruits included in a CSV file fruits.csv is imported into a database table fruits. Any failures in the import will include specification of where in the source file the invalid data originates.įollowing is a complete example where a simple CSV file is imported to a Target table Expenses. This done when when the target command is run (2).įinal step of an import is to execute ( 3-4) the actual operations towards the database to import the data. if the size of the input data will fit the targeted table columns. Once the data has been parsed some basic tests are performed to see if the properties of the data is compatible with the target table properties. ![]() The intermediary format stores the input data as Records associated with information from where the data originates. This file is then analyzed in order to detect widths, data types and their sizes based on the data, row and cell references back to the source file, and a lot more. The parse step (1) lays the foundation for the database import as it based on the source file format (csv, json, xlsx, etc), parses the data to an intermediary and internal file. The import process is explained by the following figure. Identify the target table and what target columns should be execute ![]() Parse and convert the source data to an intermediary format, and analyze the target ![]()
