db2-400

问题 Note this question is specific to "IBM DB2 for i", the IBM i operating system's version of DB2. The below screenshot shows a purposely erroneous INSERT statement that produces an SQL error of SQL0407. My question... Is there a DB2, JDBC, or other setting I can alter so the long column names are used in the error vs. the cryptic short ones? Note I used the long column names in the INSERT statement. 回答1: Carol Ramler, DB2 for i Senior Software Engineer at IBM , responded with this: In this

问题 We've been continuously working on this issue for a few months and not getting far with it. Since this was first asked, we changed the code (based on what the original developer for the site suggested), but we are still not getting where we need to be. I'm relatively new to Ruby and am currently taking some courses to learn more about it, so please bear with me. We're using Ruby 1.9 and Rails 3.2 We use AS 400/DB2 for our database. We have an online ordering site that you have to have an

问题 I'd like to run a query that gets a combination of live data and metadata for a regularly changing list of table names. This is for research & analysis on a large server with 100+ schemas and thousands of tables/views in each. I need help referring to table names dynamically, which I do understand is NOT possible. However... My googling indicates the solution may be an SQL statement in a text variable, which is then executed by the EXEC statement. But this is DB2/400 v7r3, which is a complex

问题 I'm running DB2 for i, V7R2 TR3. I was told opening a cursor provides a lot of overhead and should be avoided whenever possible. From what I've read, using EXECUTE INTO var1 USING var2 is an alternative, but I can't get it working. I am getting a SQL0104 error. This is my Stored Procedure: BEGIN DECLARE STMT1 VARCHAR ( 500 ) ; SET STMT1 = 'SELECT SUBSTR (''' || TRIM(ITEM) || ''' , ( LENGTH ( TRIM ( PREFIX ) ) + 1 ) , ( 20 - LENGTH ( TRIM ( PREFIX ) ) ) ) ' || 'FROM MYLIB.MYTABLE ' || 'WHERE

问题 Has anyone used the ibm_db package with IBM's Python for PASE to update Db2 files on IBM i (formerly AS/400)? I want to use Python scripts (from QSH) to update the Db2 database. My purpose is to populate values at runtime and update the fields of Db2 files. It works with static (hardcoded) values, but not dynamic ones. Here is what I am trying, but it is not working: import ibm_db c1 = ibm_db.connect('*LOCAL','userid','password') sql = """INSERT INTO TEMPLIB.TEMPPF (TYPE, DRPARTY, CRPARTY,

问题 I am having some issues converting a string (yyyymmddhhiiss) to a date using TRANSLATE. If I use a string directly then it works perfectly fine, but when i use a field of exactly same datatype, varchar(14), then it throws the error from the title.

问题 I am very new in iseries/DB2. We use V7R3. We have table that is generated every day by RPG program as physical file. For accessing the table data from java we use jt400.jar jdbc driver. Most of the table queries work fine but some complex queries that are using "DENSE_RANK() OVER(ORDER BY" and "ROW_NUMBER() OVER(PARTITION BY" time to time hanging and causing CPU 100%. only killing the job on AS400 side is resolving the issue. in the AS400 log I see: Job 969954/QUSER/QZDASOINIT started on 02
