Wikimedia\Rdbms\DatabaseSqlite::databasesAreIndependent | ( | ) |
Returns true if DBs are assumed to be on potentially different servers.
In systems like mysql/mariadb, different databases can easily be referenced on a single connection merely by name, even in a single query via JOIN. On the other hand, Postgres treats databases as logically separate, with different database users, requiring special mechanisms like postgres_fdw to "mount" foreign DBs. This is true even among DBs on the same server. Changing the selected database via selectDomain() requires a new connection.

Run a query and return a QueryStatus instance with the query result information.
This is meant to handle the basic command of actually sending a query to the server via the driver. No implicit transaction, reconnection, nor retry logic should happen here. The higher level query() method is designed to handle those sorts of concerns. This method should not trigger such higher level methods.
The lastError() and lastErrno() methods should meaningfully reflect what error, if any, occurred during the last call to this method. Methods like executeQuery(), query(), select(), insert(), update(), delete(), and upsert() implement their calls to doQuery() such that an immediately subsequent call to lastError()/lastErrno() meaningfully reflects any error that occurred during that public query method call.
For SELECT queries, the result field contains either:
For non-SELECT queries, the result field contains either:

Get a row ID from the last insert statement to implicitly assign one within the session.
If the statement involved assigning sequence IDs to multiple rows, then the return value will be any one of those values (database-specific). If the statement was an "UPSERT" and some existing rows were updated, then the result will either reflect only IDs of created rows or it will reflect IDs of both created and updated rows (this is database-specific).

Insert row(s) into a table, in the provided order, while deleting conflicting rows.
Conflicts are determined by the provided unique indexes. Note that it is possible for the provided rows to conflict even among themselves; it is preferable for the caller to de-duplicate such input beforehand.
Note some important implications of the deletion semantics:
This operation will be seen by affectedRows()/insertId() as one query statement, regardless of how many statements are actually sent by the class implementation.

For example, "user" can be converted to "myschema.mydbname.user" for convenience. Appearances like user

Calling this twice will completely clear any old table aliases. Also, note that callers are responsible for making sure the schemas and databases actually exist.
