Where Clause

When searching game information, you can use a specific column value for your search as well as the inDate of rows.
Searching by the where clause is used for Get, Update, and Delete.

Searching by nicknames is available when a user nickname exists in a row of the table.

Where where = new Where();
where.Equal("key", "backEnd");
where.GreaterOrEqual("size", 15);
