DO 5.0.3, SQLite 1.0.87

I have added a view manually to a SQLite database that contains a recursive query (part of a much bigger query btw):

WITH RECURSIVE fn(x) AS (VALUES(2) UNION ALL SELECT x+1 FROM fn WHERE x<13) SELECT strftime('%Y%m', date('2013-11-01'), '+' || x || ' months') FiscalMonth FROM fn

When using DO to open the database, I get the following exception

System.Data.SQLite.SQLiteException was unhandled   HResult=-2147467259   Message=database disk image is malformed malformed database schema (MasertAccountPeriodsView) - near "fn": syntax error   Source=mscorlib   ErrorCode=11   StackTrace:

Interestingly, if I open a SQLiteConnection manually - no issues when the connection opens, and if I then subsequently open a session with DO (while the manual SQLiteConnection is still open), no exception is raised.

One Answer:

Hello Craig Dunstan.

In some versions of SqLite views with incorrect definitions in select clause may damage all schema. Execute command .schema in command prompt client of SqLite for database. It must show all CREATE statements. Post response to comment. If response is too big then post just CREATE VIEW statements

Thanks for the prompt response. Below shows the issue.

create view AccountPeriodsView as select distinct MasterAccountId AMID, ma.Name AccountName, ma.State, FiscalPeriods.FiscalMonth, l.BusinessUnit, l.Id as LineId from MasterAccountAssignments maa join MasterAccounts ma on ma.Id = maa.MasterAccountId join ( WITH RECURSIVE fn(x) AS (VALUES(2) UNION ALL SELECT x+1 FROM fn WHERE x<13) SELECT strftime('%Y%m', date('2013-11-01'), '+' || x || ' months') FiscalMonth FROM fn
) FiscalPeriods join Lines l

Thanks in advance and apologies for brevity - limited characters!
