where TRUNC(sjgxsj, 'DD') >= v_run_dt
and zqxzdm = '10'
union all
SELECT ADB_XXFW_WBZQJXQCXX.ZQDM

a.fxqc qc,
b.fddqr,
a.maxjxr,
a.fxpl,
months_between(b.fddqr, a.maxjxr),
months_between(b.fddqr, a.maxjxr)/a.fxpl,
floor(months_between(b.fddqr, a.maxjxr)/a.fxpl) r1,
ceil(months_between(b.fddqr, a.maxjxr) / a.fxpl) rn --计算生成的期次数
from tmp_adb_xxfw_wbfjzqjxq_01 a, adb_xxfw_wbzq b
where a.zqdm = b.zqdm
and a.maxjxr < b.fddqr


六、sqrt(37) --37的平方根
