795367402,MDU6SXNzdWU3OTUzNjc0MDI=,1209,v0.54 500 error from sql query in custom template; code worked in v0.53; found a workaround,11788561,open,0,,,1,2021-01-27T19:08:13Z,2021-01-28T23:00:27Z,,NONE,,"v0.54 500 error in sql query template; code worked in v0.53; found a workaround

**schema:**   
CREATE TABLE ""talks"" (""talk"" TEXT,""series"" INTEGER, ""talkdate"" TEXT)  
CREATE TABLE ""series"" (""id"" INTEGER PRIMARY KEY, ""series"" TEXT, talks_list TEXT default '', website TEXT default '');

**Live example of correctly rendered template in v.053:** https://cosmotalks-cy6xkkbezq-uw.a.run.app/cosmotalks/talks/1

**Description of problem:** I needed 'sql select' code in a custom row-mydatabase-mytable.html template to lookup the series name for a foreign key integer value in the talks table.  So `metadata.json` specifies the `datasette-template-sql` plugin.

The code below worked perfectly in v0.53 (just the relevant sql statement part is shown; full code is [here](https://github.com/jrdmb/cosmotalks-datasette/blob/main/templates/row-cosmotalks-talks.html)):

```
{# custom addition #}  
{% for row in display_rows %}  
    ...  
    {% set sname = sql(""select series from series where id = ?"", [row.series]) %}  
    <strong>Series name: {{ sname[0].series }}  
    ...  
{% endfor %}  
{# End of custom addition #}  
```

**In v0.54, that code resulted in a 500 error with a 'no such table series' message.**  A second query in that template also did not work but the above is fully illustrative of the problem.

All templates were up-to-date along with datasette v0.54.

**Workaround:** After fiddling around with trying different things, what worked was the syntax from [Querying a different database from the datasette-template-sql github repo](https://github.com/simonw/datasette-template-sql#querying-a-different-database) to add the database name to the sql statement:

`{% set sname = sql(""select series from series where id = ?"", [row.series], database=""cosmotalks"") %}`

Though this was found to work, it should not be necessary to add `database=""cosmotalks""` since per the `datasette-template-sql` README, it's only needed when querying a different database, but here it's a table within the same database.
