Changelog

v10.0.0

Changes:

  • Breaking: replaced SQLGlot annotations with comments. Now comments can be preserved after transpilation, and they can appear in other places besides SELECT's expressions.

  • Breaking: renamed list_get to seq_get.

  • Breaking: activated mypy type checking for SQLGlot.

  • New: Azure Databricks support.

  • New: placeholders can now be replaced in an expression.

  • New: null safe equal operator (<=>).

  • New: added formats for TSQL's DATENAME/DATEPART functions.

  • New: added styles for TSQL's CONVERT function.

  • Improvement: refactored the schema to be more lenient; before it needed to do an exact match of db.table, now it finds table if there are no ambiguities.

  • Improvement: allow functions to inherit their arguments' types, so that annotating CASE, IF etc. is possible.

  • Improvement: allow joining with same names in the python executor.

  • Improvement: the "using" field can now be set for the join expression builders.

  • Improvement: qualify_columns now qualifies only non-alias columns in the having clause.
