db2-400

问题 I have a very simple .Net Core app trying to create and open a connection to a DB2 database (on AS/400). I have this error when I try to create the DBConnection object, with the message: ERROR 58005 SQL0902 There are no context policies. Function: AESEncryptADONet .

问题 Using ODBC driver, ibm-iaccess-1.1.0.10-1.0.amd64, on Debian Linux. When I perform a php sql query and validate the response, I see some of the data returned is not valid utf-8. mb_check_encoding returns 'false' and the character on screen in a chrome browser is the diamond question mark character. This happens on a few CHAR field types. if(!mb_check_encoding($row["field"])) { ... exit with utf-8 error } I can work around this by converting from UTF-8 to UTF-8: mb_convert_encoding($row["field

问题 I'm new in Regex I need to count and extract tokens from the below sample text: AA||CCCCCCCC|||FFFFFFFFFFF Requesting 4th token I must get a empty '' string, requesting 6th I must get 'FFFFFFFFFFF' Would it be possible to have such regex? Thanks in Advance! PS: For token counting I've used '\|' adding +1 to the result is the string is not empty, surely there another more efficient way to do that using just a regex... 回答1: For DB2 please try this to get the 6th element in the list. This works

问题 I have found that the command DSPF (Display Physical file) does not correctly display records that contain a null. If I define a physical file in DDS with the ALWNULL keyword on a field, then fill the file with data, DSPF will correctly display the data for records without nulls, but all records that contain at least one null will display only blanks in both the null and the non-null fields. This can be misleading. For example in the screenshot below, the seemingly blank records have data in

问题 I have the following query. And I am calculating on MYDATE column which is a DECIMAL(8, 0) data type which stores datea in numeric form in YYYYMMDD format like this 20191107. SELECT DECIMAL((TO_CHAR(TO_DATE(CAST(CAST(MYDATE AS INT) AS VARCHAR(8)), 'yyyymmdd') - 3 MONTHS, 'yyyymmdd')), 8, 0) FROM PDF_TABLE; It works fine. However, when I use the above conversion in a WHERE clause like below, query does not return anything. SELECT * FROM PDF_TABLE WHERE MYDATE = DECIMAL((TO_CHAR(TO_DATE(CAST

问题 We wrote a cleanup script in SQL(DB2) as400 to do cleanup of tables. ps we are fixing the processes that is causing the data issues. The SQL : DELETE FROM p6prodpf A WHERE (0 = (SELECT COUNT(*) FROM P6OPIPF B WHERE B.OPIID = A.OPIID)) Its simple code to check if theres a record in p6prodpf that has no record in P6OPIPF then delete the record in p6prodpf . My problem that I am facing is that there's instances where the p6prodpf is being deleted even if theres a record in P6OPIPF . Is there a

问题 I need SQL command that will insert a row after specific row. Example:- Before table Id. Name. 1. Xyz. 2. Xyz 3. Xyz Want result need to add 'Abc' data after each 'xyz' having same id like:- Id. Name. 1. Xyz. 1. Abc 2. Xyz 2. Abc 3. Xyz 3.

If you want only insert then you need to truncate your
