TIPTOP之分割split函数方法、getIndexOf、subString等、临时表创建；
范例（cnmq001）：
原：每次查询都把数据全部查询到临时表后再筛选；
现：查询到临时表的时候，增加可行的筛选条件，再二次筛选临时表的数据，进行优化；
1）临时表创建：
PRIVATE FUNCTION cnmq001_cr_tmp() DROP TABLE cnmq001_tmp CREATE TEMP TABLE cnmq001_tmp( nmbc002 LIKE nmbc_t.nmbc002, nmbc002_desc LIKE type_t.chr500, nmbc005 LIKE nmbc_t.nmbc005, nmbcdocno LIKE nmbc_t.nmbcdocno, nmbcseq LIKE nmbc_t.nmbcseq, nmbc006 LIKE nmbc_t.nmbc006, nmbc007 LIKE nmbc_t.nmbc007, nmbc007_desc LIKE nmajl_t.nmajl003, nmbcud001 LIKE nmbc_t.nmbcud001, nmbc003 LIKE nmbc_t.nmbc003, nmbc003_desc LIKE type_t.chr80, inamt LIKE type_t.num20_6, nmbc100 LIKE nmbc_t.nmbc100, nmbc101 LIKE nmbc_t.nmbc101, outamt LIKE type_t.num20_6, nmbccrtid LIKE nmbc_t.nmbccrtid, nmbccrtid_desc LIKE type_t.chr30, nmbccrtdt LIKE nmbc_t.nmbccrtdt ) BEGIN WORK #170406-00001#1 放到事务里 CALL cnmq001_ins_tmp() COMMIT WORK END FUNCTION
2）TIPTOP没有直接的split分割函数，所以走点弯路：
PRIVATE FUNCTION split_itemcount(p_arg1,p_arg2) DEFINE p_arg1 STRING DEFINE p_arg2 STRING DEFINE l_cnt INT DEFINE tok BASE.StringTokenizer #LET tok = base.StringTokenizer.create(p_arg1,p_arg2) LET tok = base.StringTokenizer.createExt(p_arg1,p_arg2,"",TRUE) LET l_cnt = tok.countTokens() RETURN l_cnt END FUNCTION
PRIVATE FUNCTION split(p_arg1,p_arg2,p_arg3) DEFINE p_arg1 STRING DEFINE p_arg2 STRING DEFINE p_arg3 INT DEFINE l_cnt INT DEFINE l_idx INT DEFINE l_retstr STRING DEFINE l_str STRING DEFINE tok BASE.StringTokenizer INITIALIZE l_retstr TO NULL #LET tok = base.StringTokenizer.create(p_arg1,p_arg2) LET tok = base.StringTokenizer.createExt(p_arg1,p_arg2,"",TRUE) LET l_cnt = tok.countTokens() IF (p_arg3 <= 0) OR (l_cnt <= 0 ) OR (p_arg3 > l_cnt) THEN LET l_retstr = NULL ELSE LET l_idx = 1 WHILE tok.hasMoreTokens() LET l_str = tok.nextToken() IF l_idx = p_arg3 THEN LET l_retstr = l_str EXIT WHILE END IF LET l_idx = l_idx + 1 END WHILE END IF RETURN l_retstr END FUNCTION
3）本人愚笨，试了几种方法，最后只能通过系统组合出来的条件，进行分割，再重组成自己所需的条件，用在临时表的查询上：
PRIVATE FUNCTION cnmq001_ins_tmp() DEFINE l_sql STRING DEFINE l_nmch006 LIKE nmch_t.nmch006 DEFINE l_nmcq006 LIKE nmcq_t.nmcq006 DEFINE l_nmck042 LIKE nmck_t.nmck042 DEFINE l_apde010 LIKE apde_t.apde010 DEFINE l_nmbb025 LIKE nmbb_t.nmbb025 DEFINE lr_tmp RECORD nmbc002 LIKE nmbc_t.nmbc002, nmbc002_desc LIKE type_t.chr500, nmbc005 LIKE nmbc_t.nmbc005, nmbcdocno LIKE nmbc_t.nmbcdocno, nmbcseq LIKE nmbc_t.nmbcseq, nmbc006 LIKE nmbc_t.nmbc006, nmbc007 LIKE nmbc_t.nmbc007, nmbc007_desc LIKE nmajl_t.nmajl003, nmbcud001 LIKE nmbc_t.nmbcud001, nmbc003 LIKE nmbc_t.nmbc003, nmbc003_desc LIKE type_t.chr80, inamt LIKE type_t.num20_6, nmbc100 LIKE nmbc_t.nmbc100, nmbc101 LIKE nmbc_t.nmbc101, outamt LIKE type_t.num20_6, nmbccrtid LIKE nmbc_t.nmbccrtid, nmbccrtid_desc LIKE type_t.chr30, nmbccrtdt LIKE nmbc_t.nmbccrtdt END RECORD #TEST 170531 by ljr DEFINE l_wc STRING DEFINE l_wc2 STRING DEFINE l_wc3 STRING DEFINE l_i INT INITIALIZE l_wc3 TO NULL CALL cl_replace_str(g_wc,"and","|") RETURNING l_wc FOR l_i=1 TO split_itemcount(l_wc,"|") LET l_wc2 = split(l_wc,"|",l_i) IF l_wc2.getIndexOf("nmbc002",1)>0 AND l_wc2.getIndexOf("nmbc002_",1)<=0 THEN LET l_wc3 = l_wc3,l_wc2," and " ELSE IF l_wc2.getIndexOf("nmbcdocno",1)>0 THEN LET l_wc3 = l_wc3,l_wc2," and " ELSE IF l_wc2.getIndexOf("nmbcseq",1)>0 THEN LET l_wc3 = l_wc3,l_wc2," and " ELSE IF l_wc2.getIndexOf("nmbc006",1)>0 THEN LET l_wc3 = l_wc3,l_wc2," and " ELSE IF l_wc2.getIndexOf("nmbccrtid",1)>0 AND l_wc2.getIndexOf("nmbccrtid_",1)<=0 THEN LET l_wc3 = l_wc3,l_wc2," and " END IF END IF END IF END IF END IF END FOR IF NOT cl_null(l_wc3) THEN LET l_wc3 = l_wc3.subString(1,l_wc3.getLength()-5) ELSE LET l_wc3 = " 1=1 " END IF #170406-00001#1---begin---insert放入excute LET l_sql = " INSERT INTO cnmq001_tmp VALUES (?,?,?,?,?, ?,?,?,?,?, ?,?,?,?,?, ?,?,? )" PREPARE cnmq001_ins_tmp2 FROM l_sql #170406-00001#1---end--- LET l_sql = " SELECT UNIQUE nmbc002,‘‘,nmbc005,nmbcdocno,nmbcseq,nmbc006,nmbc007,‘‘,nmbcud001, ", " nmbc003,‘‘,decode(nmbc006,‘1‘,nmbc103,0) inamt,nmbc100,nmbc101,decode(nmbc006,‘2‘,nmbc103,0) outamt,nmbccrtid,‘‘,nmbccrtdt ", " FROM nmbc_t ", " WHERE nmbcent = ?
