问题 I have found an exercise in the SQL book I study, which is not solved and I can not solve it. The goal is to implement a trigger that avoids overlapping contracts. If a customer with a current contract signs a new one, the end date of the previous one will be one day before the new start date. Tables given are: CREATE TABLE CLIENTS ( clientId VARCHAR2(15), DNI VARCHAR2(9), name VARCHAR2(100) NOT NULL, surname VARCHAR2(100) NOT NULL, sec_surname VARCHAR2(100), eMail VARCHAR2(100) NOT NULL,

问题 versions: - WSO2 4.6.0 - Oracle 11g I Have this procedure in an Oracle DB: PROCEDURE SEARCHCONTRACT ( CONTRACTNUM IN OKC_K_HEADERS_B.CONTRACT_NUMBER%TYPE , cur_out IN OUT RefCursor) .... The procedure is working fine! Note that cur_out IN OUT RefCursor ! I have no clue on how to handle that parameter in a DBLookup mediator! This mediator does not have any place to inform whether each parameter is "IN" or "OUT" and I'm not sure if setting the direction (IN/OUT) would be enough. Thanks in

问题 I want to create many blobs in java [in memory] and write it to Oracle table. What I want is the blob[bits inside it] to be random or sudo random so that oracle would not be able to do a lot of pre-optimization while storing the blob to the table. Something like for(1..1000000) { blob = createRandomBlob(sizeOfBlob); sqlText ="INSERT INTO test_blob (id, blob) VALUES(i, blob)"; stmt.executeUpdate(sqlText); } Can someone point what JAVA APIs I can use to create such blob[in memory rather than on
