POORA-06502: PL/SQL: numeric or value error: character string buffer too small with Oracle aggregate functions
text
Body
copied!<p>Good day gurus,</p> <p>I have a script that populates tables on a regular basis that crashed and gave the above error. The strange thing is that it has been running for close to 3 months on the production system with no problems and suddenly crashed last week. There has not been any changes on the tables as far as I know.</p> <p>Has anyone encountered something like this before? I believe it has something to do with the aggregate functions I'm implementing in it; but it worked initially.</p> <p>please; kindly find attached the part of the script I've developed into a procedure that I reckon gives the error.</p> <p>CREATE OR REPLACE PROCEDURE V1 IS</p> <p>--DECLARE</p> <pre><code> v_a VARCHAR2(4000); v_b VARCHAR2(4000); v_c VARCHAR2(4000); v_d VARCHAR2(4000); v_e VARCHAR2(4000); v_f VARCHAR2(4000); v_g VARCHAR2(4000); v_h VARCHAR2(4000); v_i VARCHAR2(4000); v_j VARCHAR2(4000); v_k VARCHAR2(4000); v_l VARCHAR2(4000); v_m VARCHAR2(4000); v_n NUMBER(10); v_o VARCHAR2(4000); </code></pre> <p>--<br> -- Procedure that populates DEMO table</p> <pre><code> BEGIN -- Delete all from the DEMO table DELETE FROM DEMO; -- Populate fields in DEMO from DEMOV1 INSERT INTO DEMO(ID, D_ID, CTR_ID, C_ID, DT_NAM, TP, BYR, ENY, ONG, SUMM, DTW, REV, LD, MD, STAT, CRD) SELECT ID, D_ID, CTR_ID, C_ID, DT_NAM, TP, TO_NUMBER(TO_CHAR(BYR,'YYYY')), TO_NUMBER(TO_CHAR(NVL(ENY,SYSDATE),'YYYY')), CASE WHEN ENY IS NULL THEN 'Y' ELSE 'N' END, SUMMARY, DTW, REV, LD, MD, '1', SYSDATE FROM DEMOV1; -- LOOP THROUGH DEMO TABLE FOR j IN (SELECT ID, CTR_ID, C_ID FROM DEMO) LOOP Select semic_concat(TXTDESC) INTO v_a From GEOT WHERE ID = j.ID; SELECT COUNT(*) INTO v_n FROM MERP M, PROJ P WHERE M.MID = P.COD AND ID = j.ID AND PROAC IS NULL; IF (v_n > 0) THEN Select semic_concat(PRO) INTO v_b FROM MERP M, PROJ P WHERE M.MID = P.COD AND ID = j.ID; ELSE Select semic_concat(PRO || '(' || PROAC || ')' ) INTO v_b FROM MERP M, PROJ P WHERE M.MID = P.COD AND ID = j.ID; END IF; Select semic_concat(VOCNAME('P02',COD)) INTO v_c From PAR WHERE ID = j.ID; Select semic_concat(VOCNAME('L05',COD)) INTO v_d From INST WHERE ID = j.ID; Select semic_concat(NVL(AUTHOR,'Anon') ||' ('||to_char(PUB,'YYYY')||') '||TITLE||', '||EDT) INTO v_e From REFE WHERE ID = j.ID; Select semic_concat(NAM) INTO v_f FROM EDM E, EDO EO WHERE E.EDMID = EO.EDOID AND ID = j.ID; Select semic_concat(VOCNAME('L08', COD)) INTO v_g FROM AVA WHERE ID = j.ID; SELECT or_concat(NAM) INTO v_o FROM CON WHERE ID = j.ID AND NAM = 'Unknown'; IF (v_o = 'Unknown') THEN Select or_concat(JOBTITLE || ' (' || EMAIL || ')') INTO v_h FROM CON WHERE ID = j.ID; ELSE Select or_concat(NAM || ' (' || EMAIL || ')') INTO v_h FROM CON WHERE ID = j.ID; END IF; Select commaencap_concat(COD) INTO v_i FROM PAR WHERE ID = j.ID; IF (v_i = ',') THEN v_i := null; ELSE Select commaencap_concat(COD) INTO v_i FROM PAR WHERE ID = j.ID; END IF; Select commaencap_concat(COD) INTO v_j FROM INST WHERE ID = j.ID; IF (v_j = ',') THEN v_j := null; ELSE Select commaencap_concat(COD) INTO v_j FROM INST WHERE ID = j.ID; END IF; Select commaencap_concat(COD) INTO v_k FROM SAR WHERE ID = j.ID; IF (v_k = ',') THEN v_k := null; ELSE Select commaencap_concat(COD) INTO v_k FROM SAR WHERE ID = j.ID; END IF; Select commaencap_concat(CONID) INTO v_l FROM CON WHERE ID = j.ID; IF (v_l = ',') THEN v_l := null; ELSE Select commaencap_concat(CONID) INTO v_l FROM CON WHERE ID = j.ID; END IF; Select commaencap_concat(PROID) INTO v_m FROM PRO WHERE ID = j.ID; IF (v_m = ',') THEN v_m := null; ELSE Select commaencap_concat(PROID) INTO v_m FROM PRO WHERE ID = j.ID; END IF; -- UPDATE DEMO TABLE UPDATE DEMO SET GEOC = v_a, PRO = v_b, PAR = v_c, INS = v_d, REFER = v_e, ORGR = v_f, AVAY = v_g, CON = v_h, DTH = v_i, INST = v_j, SA = v_k, CC = v_l, EDPR = v_m, CTR = (SELECT NAM FROM EDM WHERE EDMID = j.CTR_ID), COLL = (SELECT NAM FROM EDM WHERE EDMID = j.C_ID) WHERE ID = j.ID; END LOOP; END V1; </code></pre> <p>/</p> <p>The aggregate functions, commaencap_concat (encapsulates with a comma), or_concat (concats with an or) and semic_concat(concats with a semi-colon).</p> <p>the remaining tables used are all linked to the main table DEMO.</p> <p>I have checked the column sizes and there seems to be no problem.
