I am happy to announce the release of version 3.0 of “Firebird External Table Generator” (ext-table-gen for short).
“Firebird External Table Generator” is a commandline tool to transform CSV files to Firebird external table files (a binary format for external table data).
Compared to version 2.0, we added support for more datatypes:
Approximate numeric types (binary floating point)
float
doublePrecision
Decimal floating point type:
decfloat
String types
varchar
ext-table-gen 3.0 requires Java 21 or higher.
You can find the 3.0 release at ext-table-gen v3.0.
Documentation and release notes can be found on https://mrotteveel.github.io/ext-table-gen/.
The project itself is hosted on https://github.com/mrotteveel/ext-table-gen.
