你这上面复制的，左右括号数量都不一样多，少了一个右括号

${if(len(oop)!=0  && oop != "00000001" && len(yg)==0 &&  len(zrcy) == 0,

"select '一区', sum(jcr_1_zone) jcr

from dm_dwlwfqhz_info

where 1=1 and  gsdwh='" + oop +"'"

+if(len(tbsj_ks) == 0,"","and tjny >= '" +tbsj_ks + "'") 

+if(len(tbsj_js) == 0,"","and tjny <= '" +tbsj_js + "'")+"union

"union

+if(len(tbsj_ks)==0,"","and tjny>='" +tbsj_ks +"'")

+if(len(tbsj_js)==0,"","and tbsj_js<='" +tbsj_js +"'")

,

"")}

这个括号少了

感觉可能if的结构有点问题

可以先把语句单独拿出来，执行一下看有没有报错
