Function Alias

expr.go:124–126

Alias allows to define alias for column in SelectBuilder. Useful when column is defined as complex expression like IF or CASE Ex: .Column(Alias(caseStmt, "case_column"))

(expr Sqlizer, alias string)

// Ex:
//		.Column(Alias(caseStmt, "case_column"))
func Alias(expr Sqlizer, alias string) aliasExpr {
	return aliasExpr{expr, alias}
}

func (e aliasExpr) ToSql() (sql string, args []interface{}, err error) {
	sql, args, err = e.expr.ToSql()
