What is IceTea?

Tired of fiddling with obscure, confusing SQL files? Take a break. Have some IceTea. IceTea is a tool that converts SQL databases generated by Cumulus CI into Excel, for manual editing, and converts them back to SQL files for CCI to use.

Installation

First make sure you have Python 3 and pip. You can install Python here, but it may be pre-installed on your machine. You may also need to install pip. Instructions can be found here. TL;DR: run python -m ensurepip --upgrade on Linux/MacOS, or py -m ensurepip --upgrade on Windows. (If you get an error that the python or pip commands aren't found, try running python3 or pip3 instead.)

Then run pip install IceTeaCCI to install the tool. All done!

Usage

To import SQL data into Excel, run icetea in. To export it from Excel back to SQL, run icetea out.

Legacy commands: You can also use dataset_to_excel or ds2xl to import, and excel_to_dataset or xl2ds to export.

Arguments

Common

-i, --input: path to input file. By default, this is ./datasets/sample.sql or ./generated.xlsx for the SQL-to-XLSX or XLSX-to-SQL scripts respectively. (The assumption is that the script is run from the project folder.)

-o, --output: path to save the generated file as. The default values are the same as -i but swapped: ./generated.xlsx and ./datasets/sample.sql respectively.

Open output file:

-of, --open-file: Open the generated file once it's complete.

-nof, --no-open-file: Do not open the file.

Default behavior is to open the generated XLSX file (icetea in), but not to open the generated SQL file (icetea out).

Logging arguments (all default to off):

-ltn, --log-table-names: Display a log message for each table that is loaded/detected.

-lr, --log-records: Display a log message for each record.

-lf, --log-fields: Display a log message for each field in a table.

-sw, --suppress-warnings: Prevent warning messages from appearing.

XLSX-to-SQL Specific

Delete input file:

-d, --delete-xlsx: Delete the XLSX file after the new SQL file is generated.

-p, --preserve-xlsx: Do not delete the file.

Default behavior is to DELETE the XLSX file! This is done so that there aren't 2 competing versions of the data floating around.

Important Info/Warnings

Don't Rename Sheets or Fields

The names of the worksheets in the Excel spreadsheet are linked to the names of the tables, and the headers of each column are linked to the field names. If you want to change the name of a table or field, do it in Salesforce, not Excel. However, you can safely re-order columns or sheets.

Don't Start an XLSX File from Scratch

This tool is for editing the SQL files in Excel, not a general-purpose tool for converting XLSX data to SQL scripts. If you try to run it on an arbitrary XLSX file, it will probably fail, since the proper data won't be encoded in the comments or description (see Comments and Description below).

End Detection

Do not leave any blank columns in the XLSX file, except at the rightward edge. The tool will stop looking for fields once it sees a blank column, and any further data will be ignored. Blank rows are allowed, though discouraged.

Comments and Description

SQL databases contain information that doesn't have a direct analogue in Excel, like the PRIMARY KEY/NOT NULL constraints. This information needs to be kept along with each field, so this tool stores the info in comments attached to the field headers. Please don't edit or delete those comments!

If you modify a field header, make sure the comment goes with it! For example, to add a new field, insert a new column rather than manually copying the values rightwards. And to delete a field, delete the itself, rather than just deleting the values (see End Detection above).

Comments on the cells of records are not checked. You can feel free to leave comments there; the tool will ignore them.

Additionally, Excel limits its sheet names to 31 characters. Any table with a name longer than 29 characters will be truncated to 29 characters, with the additional 2 characters being a numerical suffix for disambiguation. Don't worry, the original table names are saved and will be restored once you run icetea out! The table names are stored in the Excel file's description in its properties. Please do not edit this either.

Anything you shouldn't touch is helpfully marked with a melodramatic "AUTOGENERATED, DO NOT EDIT!"
