Possibility to splice table names? #13

Closed Javran closed 4 years ago

Javran commented 4 years ago

Well, sorry I clicked post button way too early....

so basically I'm wondering if the following is possible:

queryStatement :: Text -> Statement (Vector Int64) (Vector Int64)
queryStatement tableName =
    [vectorStatement|SELECT foo :: int8 FROM ${encodeUtf8 tableName}|]

for now it complains about:

 unexpected "${tableName}"
 expecting table reference or white space

the error sounds like I've got the unquote syntax wrong though...

This is not supported and likely never will be since it's not the purpose of this library.
