      GCancellable* cancellable,
      GError** error
    )

#### Description [src]

Executes a SELECT statement `sql_stmt` and calls `func` for each row of the result. Use `e_cache_sqlite_exec()` for statements which do not return row sets.

Available since: 3.26

#### Parameters

`sql_stmt`

  Type: `const gchar*`

  An SQLite SELECT statement to execute.

  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

`func`

  Type: `ECacheSelectFunc`

  An `ECacheSelectFunc` function to call for each row.

`user_data`

  Type: `gpointer`

  User data for `func`.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`cancellable`

  Type: `GCancellable`

  Optional `GCancellable` object, or `NULL`.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.
