You've got it in reverse. When sucrose dissolves in water, sucrose is the solute, and water is the solvent. In order to dissolve, sucrose molecules have to be more attracted to water molecules than they are to other sucrose molecules. If the attraction of sucrose to sucrose was greater than the attraction of sucrose to water, then there would be no reason for the solid sucrose to turn into the aqueous sucrose solution. Sucrose molecules would simply remain firmly attached to each other if that were the case.

sucrose + water = glucose + fructose is the chemical equation for the hydrolysis of sucrose into glucose and fructose.

The disaccharide molecule, sucrose is not formed from two glucose molecules. Sucrose is formed from one glucose molecule and one fructose molecule.

Sucrose is a disaccharide composed of one molecule of glucose connected via an α(1-2) glycosidic bond to one molecule of fructose.

Sucrose is a covalently bonded compound. Sucrose is generally extracted from sugar cane sugar beet and then purified and crystallized. Other (minor) commercial sources are sorghum and sugar maples.
