delphi 'select count(*)'统计查询？

sSql := 'select count(*) as RECORDR, sum(ZSL) as ZSLR, sum(ZJE)' +
'as ZJER, sum(SPCB) as CBJR, sum(QTCB) as QTCBR, sum(LR) as LRR from T_SALES group by Extract(MONTH From SALEDATE)';

用上面这个语句分月查询,但是日期没有显示出来呢，
销售日期我想显示为：2019年4月 这样的每个月显示一条记录。

select count(*) as RECORDR, sum(ZSL) as ZSLR, sum(ZJE) as ZJER, sum(SPCB) as CBJR, sum(QTCB) as QTCBR, sum(LR) as

你这里也没有查询日期列，当然不会有日期显示。
