TSQLiteServer::TSQLiteServer | ( | const char * | db, |
const char * | uid = nullptr , |

const char * | pw = nullptr |

) |
Open a connection to an SQLite DB server.
The db arguments should be of the form "sqlite://<database>", e.g.: "sqlite://test.sqlite" or "sqlite://:memory:" for a temporary database in memory. Note that for SQLite versions >= 3.7.7 the full string behind "sqlite://" is handed to sqlite3_open_v2() with SQLITE_OPEN_URI activated, so all URI accepted by it can be used.

List all columns in specified table (database argument is ignored).
Wild is for wildcarding "t%" list all columns starting with "t". Returns a pointer to a TSQLResult object if successful, 0 otherwise. The result object must be deleted by the user. For SQLite, this fails with wildcard, as the column names are not queryable! If no wildcard is used, the result of PRAGMA table_info(table) is returned, which contains the names in field 1.
