Question

Using OrmLite with android I have tried experimenting with a simple query:

GenericRawResults<String[]> results = queryRaw("SELECT * FROM transaction");

Unfortunately I recieve an exception:

near "transaction": syntax error: , while compiling: SELECT * FROM transaction

I found this confusing, and after stepping through and seeing what the Orm generates through compiled statements I realised the syntax should be:

GenericRawResults<String[]> results = queryRaw("SELECT * FROM `transaction`");

I am just slightly confused as to why this is required?

Answer 1

"Transaction" is an SQLite3 keyword.

Relevant quotes from that page, up at the very very top:

The SQL standard specifies […] keywords which may not be used as the names of tables […]
[…]
If you want to use a keyword as a name, you need to quote it.
