Member Function Documentation

isHealthy()

bool lintel::sqlite::Connection::isHealthy

(

)

const

Lightweight liveness probe.

Runs SELECT 1 on the open handle instead of reading sqlite3_errcode, because the error code stays set after a non-fatal error (e.g. a constraint violation) and would wrongly report a healthy connection as broken.

Returns

true when the connection answered SELECT 1
