SQLite couldn’t parse the statement; the token after “near” is where it stopped.

The query references a column that doesn’t exist in the table (or an unquoted string being read as a column).
SQL Server: Invalid column name 'x'. (Msg 207)
SQL Server can’t find the column — typo, missing migration, or a string in double quotes with QUOTED_IDENTIFIER ON.
ORA-12154: TNS:could not resolve the connect identifier specified
The Oracle client couldn’t find the alias in tnsnames.ora (or the naming method can’t resolve it).
