This is a Query Outer Join Left icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,600 icons, all in the same style and quality.
The icon is a depiction of two circles, one shaded with dots and one empty. The empty circle is overlapping the shaded one. The icon is representative of a relational database query option, to join-left one query with another.
