这段代码哪里有错误呢

if (pastart = -1) sql.append("select * from("); sql.append("select nid,sname,sdescription,nprice,sif (pastart = -1)sql.append("select * from(");sql.append("select nid,sname,sdescription,nprice,simg,(CASE smctag WHEN '0' THEN '有货'WHEN '1' THEN '
你最后把 sql语句输出来 放进去查询看看 就知道那里错了

if (pastart = -1) sql.append(select * from(); sql.append(select nid,sname,sdescription,nprice,sif (pastart = -1)sql.append(select * from();sql.append(select nid,sname,sdescription,nprice,simg,(CASE smctag WHEN '0' THEN '有货'WHEN '1' THEN ' 1 sq.ft = how many sq.meters 循环队列的空条件A (sq.rear+1)%Maxsize==(sq.front+1)%Maxsize B (sq.rear+1)%Maxsize==sq.front+1 C (sq.rear+1)%Maxsize==sq.front D sq.rear==sq.front 2.下列程序运行的结果是?typedef char datatype;void main(){Sequeue *sq; datatype x=’e’,y=’c’; int i; SETNULL(sq); ENQUEUE(sq,’h’); ENQUEUE(sq,’r’); ENQUEUE(sq,y); x= DEQUEUE(sq); ENQUEUE(sq,x); x= DEQUEUE(sq); ENQUEUE(sq,’a 1 Hz :0.00005 G sq/H（可靠性振动测试中是什么意思）1) Truck test profile1 Hz :0.00005 G sq/Hz4 Hz :0.01 G sq/Hz16 Hz :0.01 G sq/Hz40 Hz :0.001 G sq/Hz80 Hz :0.001 G sq/Hz200 Hz :0.00001 G sq/Hz(30 mins for each axis)2) Air test profile2 1sq.ft等于多少平方米如题! 1sq.ft等于多少平方米知道的就是说来!或者是250sq.ft等于多少平方米 在等差数列中,Sn为{an}的前n项和,q、p∈N*且p≠q.(1)若Ap=q,Aq=p,求证Ap+q=0 (2)若Sp=Sq,求证：Sp+q=0(3)若Sp=q,Sq=p,求证Sp+q=-（p+q） huffman编码已知：信源符号个数q,信源符号S0,.,Sq-1,信源概率分布P0,...,Pq-1,算法：1,如果q=2,则返回编码：s0->0,s1->12,否则a,重新排序S0,.,Sq-1,和P0,.Pq-1b,创建一个符号s’,其概率为P’=Pq-2+Pq-1c,递归调 证明在等差数列中,1.（Sp-Sq）/(p-q)=(Sp+Sq)/(p+q) 2.若Sm=Sn,则S(m+n)=0 已知等差数列{an}中Sp=Sq(p不等于q),求Sp+q 已知：S＞PP+R＞Q+SQ+R=P+S排列PQRS的大小 sq.ft是什么单位?
