I have set up FTS5 (full-text search) with virtual tables in sqlite. MATCH queries are working except it always throws a syntax error on initial token queries.
For example: SELECT * FROM fts_article WHERE fts_article MATCH '^suo' throws
Error calling sqlite3_step (1: fts5: syntax error near "^") rs
I've tried all the syntax variations listed in the docs, getting the same error.
(In production code I will be using bound parameters, and I've tried it that way also.)
UPDATE: Some additional context: I am using the sqlite baked into libsqlcipher-ios.a from SQLCipher. And I am running my sql through FMDB. I have tried calling the sqlite api directly. In that case, the error seems to go away but I'm not seeing the results I expect. Still investigating ...

I am using airflow 2.0.2 to connect with databricks using the airflow-databricks-operator. The SQL Operator doesn't let me specify the database where the query should be executed, so I have to prefix the table_name with database_name. I tried reading through the doc of databricks-sql-connector as well here -- https://docs.databricks.com/dev-tools/python-sql-connector.html and still couldn't figure out if I could give the database name as a parameter in the connection string itself.
I tried setting database/schema/namespace in the **kwargs, but no luck. The query executor keeps saying that the table not found, because the query keeps getting executed in the default database.
Right now it's not supported - primarily reason is that if you have multiple statements then connector could reconnect between their execution, and result of use will be lost. databricks-sql-connector also doesn't allow setting of the default database.
Right now you can workaround that by adding explicit use <database> statement into a list of SQLs to execute (the sql parameter could be a list of strings, not only string).
P.S. I'll look, maybe I'll add setting of the default catalog/database in the next versions
I'm trying to use a SQLite database a linked server in SSMS. I've managed to get the ODBC driver installed and a linked server created, but I can't seem to find a way to get queries to work. I think it's just a matter of not understanding the proper syntax for it. Here's what I've tried:
exec sp_tables_ex 'SQLITE'
This works as expected, showing all of the tables in the database.
select * from SQLITE.[default].dbo.TRANSLATION
Fails with this error message
Invalid use of schema or catalog for OLE DB provider "MSDASQL" for
linked server "SQLITE". A four-part name was supplied, but the
provider does not expose the necessary interfaces to use a catalog or
schema.
Taking a clue from that, I tried removing the schema:
select * from SQLITE.[default].TRANSLATION
But this gives me another error message:
Invalid object name 'SQLITE.default.TRANSLATION'.
Likewise, the following give the same error (with slight changes for the object name):
select * from SQLITE.[default].TRANSLATION
select * from SQLITE.dbo.TRANSLATION
select * from SQLITE.TRANSLATION
Any ideas? I'm not quite sure what to try from here.
In a brand new MS Access 2010 database, I linked to two tables from a SQLite database using an ODBC connection. I have the following union query:
SELECT Calibration_Header.Gage_ID FROM Calibration_Header
UNION SELECT CHArchive.Gage_ID FROM CHArchive;
If I execute this SQL against the same database using the sqlite3 command line application, it runs successfully and returns the proper data. When I run the query in the MS Access 2010 database, I get the following error message:
ODBC--call failed.
near "(": syntax error (1) (#1)
Other union queries against different tables get the same error message when run in MS Access. When run in the sqlite3 command line, they run successfully and return the proper data.
I suspect that a UNION SELECT is not in the standard Access vernacular. You can try implementing ANSI-92 in Access 2010 and then running your query as code, as described by Albert Kallal at http://www.utteraccess.com/forum/Create-View-Access-t1924479.html&p=1924500#entry1924500. I used these instructions to successfully create an Access "view".
I realise that this is a very old thread, but I have just had this problem and found a pretty simple solution, so thought it worth sharing in case anyone else has the problem. Although Access seems unable to run a UNION query on two linked tables, if you create a pass-through query and put the SQL for the UNION in there, it works ok. Presumably the SQL is then executed by SQLite and the results returned as a single resultset, rather than Access itself trying to apply the UNION to two separate resultsets.
I am unable to test in earlier versions, but it works in Access 2016.
When I use the flash.data routines to issue a SQLite "PRAGMA encoding" statement, I get an error suggesting that this isn't supported:
'Error #3115: SQL Error.', details:'PRAGMA is not allowed in SQL.', operation:'execute', detailID:'2005
Is there a workaround?
In a word no. See for supported and unsupported features.

System table access is not available
The system tables including sqlite_master and other tables with the "sqlite_" prefix are not available in SQL statements. The runtime includes a schema API that provides an object-oriented way to access schema data. For more information see the SQLConnection.loadSchema() method.
For a more detailed help in using loadSchema have a look at,

and consider using,

I have created a connectionstring in mvc3 application and it is working fine in mvc views and controllers and I am able to fetch data. Now I have called the repository/model functions in a Unit Test in Test project and I am getting error:
System.Data.EntityCommandExecutionException: An error occurred while executing the command definition. See the inner exception for details. ---> System.Data.SqlClient.SqlException: Invalid object name 'dbo.tblProduct'.
How can i fix it?
That has nothing to do particularly with MVC. As it seems, when testing, you use ConnectionString on database that does not have 'dbo.tblProduct' table/view. Check the connetion string and database. You may need to debug tests
Check your table may have different schema (other then dbo) change it to dbo using query below
look at this.
How do I change db schema to dbo
Its very strange for my case, as it is required to do mapping between model and tables, the name has to be the same. When I added 's' at the end of table's name, it works. I don't know if this part work of what LINQ does.
