问题 I have this query: SELECT INVOICE_NUMBER, INVOICE_SEQ_NUMBER, FILE_NUMBER, MAX(INVOICE_SEQ_NUMBER) OVER (PARTITION BY INVOICE_NUMBER) AS MAX_INV_SEQ_NUM FROM (SELECT A.INVOICE_NUMBER, A.INVOICE_SEQ_NUMBER, B.FILE_NUMBER, DENSE_RANK() OVER (ORDER BY A.INVOICE_NUMBER) as seqnum FROM TABLE1 A JOIN TABLE2 B ON A.INVOICE_NUMBER = B.INVOICE_NUMBER AND A.INVOICE_SEQ_NUMBER = B.INVOICE_SEQ_NUMBER ) t WHERE seqnum <= 500; It was working fine with 10000 records in the tables but we added more today(

问题 I'd like to put a constraint, a check or a foreign key, on two combined fields from table1 to another field in table2. Here is what I tried, but both gave me errors: ALTER TABLE table1 ADD CONSTRAINT foo CHECK (field1 || field2 IN (SELECT fieldx FROM table2)); ALTER TABLE table1 ADD CONSTRAINT foo FOREIGN KEY (field1 || field2) REFERENCES table2 (fieldx); Is this possible? If yes, how? Beside this, is it generally possible to use subselects in CHECK Constraints? I'm using DB2/LINUX 9.5.0.

问题 I am using struts and hibernate application. I have a problem while fetching records from DB2 via hibernate. I am getting this error 14:22:17,804 WARN [JDBCExceptionReporter] SQL Error: -204, SQLState: 42704 14:22:17,804 ERROR [JDBCExceptionReporter] DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=DB2ADMIN.TABLENAME, DRIVER=3.57.82 14:22:17,804 WARN [JDBCExceptionReporter] SQL Error: -727, SQLState: 56098 14:22:17,804 ERROR [JDBCExceptionReporter] DB2 SQL Error: SQLCODE=-727, SQLSTATE

问题 I'm trying to modify a script that has a very basic SELECT query running on DB2. I need to store that result set, preferably in an array chunk so I can run it in batches, but in an array nonetheless, and then I need to use those values in an INSERT/SELECT on MYSQL. I'm thinking, after some feedback, that I might have to use the DB2 results as constants but I don't really know how to go about that. Here is a mock up of how I am selecting, and how I then need to insert based on the select

问题 In GetEmpIDInBytes_INDIRECT method listed below, I get the following exception: Unable to cast object of type 'System.String' to type 'System.Byte[]'. I know that this error can be avoided if I use the following line (i.e. encoding instead of byte[] casting) result = Encoding.ASCII.GetBytes(odbcCommand.ExecuteScalar().ToString()); But I cannot use the encoding since I don’t know what was the encoding used in the DB2 function. I need to get it back from DB2 as byte[]. How can we get it? CODE

问题 I am using DB2 LUW in a windows machine. I want to get the logs for DDL & DML queries used in the database. The default logs(for example S000001.LOG) contains 'null' and not in a readable format. So I enabled auditing and extracted the archived audit logs into .del files. But the audit log extraction creates .del like this: execute.del "2019-09-05-01.19.44.443001","EXECUTE","STATEMENT",13,0,"TEST2","Administrator","ADMINISTRATOR","ADMINISTRATOR",,,"*LOCAL.DB2.190904193137","db2bp.exe",,,,,,,,

问题 I am trying to connect a db2 database using php. Now, i am gonna write some code similar to this(call a stored procedure): $proc = 'CALL MyLib.MySP(?, ?, ?)'; $stmt = db2_prepare($conn, $proc) or die("db2_prepare failed<br>"); // Define input variable values // $paramIN1 = ...; $paramIN2 = ...; $paramOUT3 = ""; // Define parameters // db2_bind_param($stmt, 1, "paramIN1", DB2_PARAM_IN); db2_bind_param($stmt, 2, "paramIN2", DB2_PARAM_IN); db2_bind_param($stmt, 3, "paramOUT3", DB2_PARAM_OUT); //

问题 I made the following programs in Perl before: my $db = DBconnection with DB2 if ($pid = fork()) { #parent } else { #child $db->execute("SELECT ****"); exit; } wait(); $db->execute("SELECT ****"); I thought that it waited for the end of the child process to have wanted to do it and would operate it for DB by a pro-process. In addition, DB is not connected to the contents of the error. What's wrong? 回答1: There is a lot of stuff you must do to allow a child process to use its parent's DBI handle

问题 I have an "insert only" database, wherein records aren't physically updated, but rather logically updated by adding a new record, with a CRUD value, carrying a larger sequence. In this case, the "seq" (sequence) column is more in line with what you may consider a primary key, but the "id" is the logical identifier for the record. In the example below, This is the physical representation of the table: seq id name | CRUD | ----|-----|--------|------| 1 | 10 | john | C | 2 | 10 | joe | U | 3 |

问题 I'm using this to compare Year and month, but it failing when month is less than current month even though the year is greater than current year SELECT * FROM DUMMY_TABLE WHERE YEAR(PREV_ELIG_REV_DT) >= YEAR(CURRENT TIMESTAMP) AND MONTH(PREV_ELIG_REV_DT) >= MONTH(CURRENT TIMESTAMP) 回答1: You could add and extra condition to match the situation when the YEAR is equal.. SELECT * FROM DUMMY_TABLE WHERE YEAR(PREV_ELIG_REV_DT) > YEAR(CURRENT TIMESTAMP) OR ( YEAR(PREV_ELIG_REV_DT) = YEAR(CURRENT
