alter table, drop column error- syntax error, unexpected $end, expecting BETWEEN or IN or SQL_TOKEN_LIKE

Hi everyone, I am using LO Base, Firebird.

I am trying to drop the column is_in_collection from the table samples. However, when running the following query:

ALTER TABLE “samples” DROP “is_in_collection”;

I get the error below:

1: firebird_sdbc error:
*unsuccessful metadata update
*ALTER TABLE samples failed
*column is_in_collection does not exist in table/view samples
caused by
‘ALTER TABLE “samples” DROP “is_in_collection”’

Could it be that the separators in the field name are hyphens or spaces? Double L mismatch? Addressing the wrong table (similar names)?

Another item to check is for an inadvertent space(s) at the end of the field name. Hard to discern but have seen it happen in another post.
