Methods

bindByIndex()

Binds a to the specified index.

void bindByIndex(
  in unsigned long aIndex,
  in nsIVariant aValue
);

Parameters

aIndex

The zero-based numerical index for the parameter to be bound. This will be one less than the number used in the SQL (<code>?1</code> maps to <code>0</code>, and so on).

aValue

to be bound to the specified index.

bindBlobByIndex()

Binds a blob to the specified index.

void bindBlobByIndex(
  in unsigned long aIndex,
  [array, const, size_is(aValueSize)] in octet aValue,
  in unsigned long aValueSize
);

Parameters

aIndex

The zero-based numerical index for the parameter to be bound. This will be one less than the number used in the SQL (<code>?1</code> maps to <code>0</code>, and so on).
