What did you define SQLITE_MAX_ATTACHED as when you compiled the DLL? The default limit is 10. You can dynamically decrease the limit to be less than the compile time limit, but you cannot increase it beyond the maximum set when you compiled the library.
https://sqlite.org/limits.html 11. Maximum Number Of Attached Databases The ATTACH statement is an SQLite extension that allows two or more databases to be associated to the same database connection and to operate as if they were a single database. The number of simultaneously attached databases is limited to SQLITE_MAX_ATTACHED which is set to 10 by default. The maximum number of attached databases cannot be increased above 125. The maximum number of attached databases can be lowered at run-time using the sqlite3_limit(db,SQLITE_LIMIT_ATTACHED,size) interface. -- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. >-----Original Message----- >From: sqlite-users <sqlite-users-boun...@mailinglists.sqlite.org> On >Behalf Of Keith Bertram >Sent: Wednesday, 15 January, 2020 12:50 >To: SQLite mailing list <sqlite-users@mailinglists.sqlite.org> >Subject: Re: [sqlite] sqlite3_limit equivalent in System.Data.SQLite.dll > >Hello, > >I'm attempting to use the new SetLimitOption added to the 1.0.112 version >of System.Data.SQLite.dll.
