This is a:

  • bug fix PR with no breaking changes — please ensure the base branch is master
  • [-] new functionality — please ensure the base branch is the latest dev/ branch
  • [-] a breaking change — please ensure the base branch is the latest dev/ branch

Description & motivation

Checklist

  • I have verified that these changes work locally on the following warehouses (Note: it's okay if you do not have access to all warehouses, this helps us understand what has been covered)
    • BigQuery
    • Postgres
    • Redshift
    • Snowflake
  • I have "dispatched" any new macro(s) so non-core adapters can also use them (e.g. the star() source)
  • I have updated the README.md (if applicable)
  • I have added tests & descriptions to my models (and macros if applicable)
  • I have added an entry to CHANGELOG.md

" SQL-Error [42000]: syntax error, unexpected '*' "
If you specify the * in the unioned with their respectiv names <name>.* you do not receive the SQL Error posted above. This should not inflict any further problems since it is redundant for most DBs.

Hi @TimoKruth, I'm not familiar with SQL 42000 and Google hasn't been much help to me. Is this a stylistic issue, or does Exasol reject * references without a table/CTE name?

As a rule, dbt-utils commits to support for the key four adapters (Snowflake, BigQuery, Postgres and Redshift), with other adapters able to override specific functionality with secondary packages (e.g. spark-utils.

Given that this isn't a functional change and will be compatible with the above DBs, I'm not averse to it; I'm just curious about the problem it aims to solve, and whether there are other macros in this package that might have more complex problems

Hi @joellabes SQL 42000 seems to be quite generic as a code on the Exasol. And it is like you describe it: Exasol rejects the * references in this case because it seems to not be able to clearly evaluate which "table/with" it should look at. I wouldn't open an issue on a style issue actually but the Exasol just quits with " SQL-Error [42000]: syntax error, unexpected '*' " right there.
I would love a fix if it does not affect any other DBs since it is only more clear than before.
I hope this helps and feel free to ask if you need further clarification on the error and if you need a test on an exasol you may refer to me in comments

* Add col_name alias to else state too (#437)

* Remove extra semicolon in `insert_by_period` materialization (#439)

* Remove extra semicolon in `insert_by_period` materialization.

`create_table_as()` generates a SQL statement that already ends with a semicolon, so the extra semicolon after a `create_table_as()` call in the `insert_by_period` materialization ends up being an empty SQL statement, and at least when using Snowflake this causes the dbt run to fail with a "cannot unpack non-iterable NoneType object" error.

* Update changelog for PR 439.

* Use the relation object passed into get_column_values, instead of making our own (#440)
