SQL0802 - Data Conversion or Data Mapping Error

早过忘川 提交于 2019-12-24 14:34:04
问题 I'm am trying to write a query that calculates some numbers on the servers side, rather than after the data is pulled. I keep getting the SQL0802 error. I have tried a regular Sum as well as Double and float commands. I think the return is to long. I'm using SQL Squirrel so I went and removed the decimal place restriction to see if that would fix the problem. It is the "Gross Margin" calculation that is throwing it off. The rest of the calculations work fine. I appreciate any help i can get.

问题 In the below code I am comparing the two Resultset of the tables S_R_VAL and R_VAL. I need to compare S_NUMBER (from S_R_VAL table) and S_NO (from R_VAL table). While comparing I am getting this error "java.lang.RuntimeException: The two ResultSets contains different number of columns! . Please help in fixing this error. String SSQ = "select DISTINCT S_NUMBER from OTG.S_R_VAL" + " WHERE R_TS = (SELECT MAX(R_TS) FROM OTG.S_R_VAL) order by S_NUMBER"; String SDS = "SELECT DISTINCT S_NUMBER FROM

DB2 SQL Query Trim inside trim

不问归期 提交于 2019-12-24 13:42:46
问题 I am transferring some SQL query into C# code, now I am having problem understand the following query. So far my understanding to the following query is: If PREFIX is between 0 to 99 , then trim PREFIX , but what does || '-' || mean here? My understanding for line 3 is after finishing the trim function in line 2, do another trim, but I do not recognize the syntax in line 3 either . This is DB2. RETURN CASE WHEN PREFIX BETWEEN '00' AND '99' //line 1 THEN TRIM(PREFIX) || '-' || //line 2 TRIM

How can I insert additional libraries to my jdbc/DB2 connection?

天大地大妈咪最大 提交于 2019-12-24 12:50:17
问题 I'm writing a little java program to write data in a AS/400 DB2 table via jdbc (db2jcc.jar version 1.0.581) and a trigger is associated to the INSERT operation. This trigger works on various tables associated with libraries different from that (jdta73p10) which contains my table (f4104). Follows the code I use to establish connection and read data that perfectly runs. import java.sql.*; import com.ibm.db2.jcc.*; public class ProvaNUMEAN13 { public static void main(String[] args) throws

Library List is not being used in remote PHP DB2 connection to IBM i

前提是你 提交于 2019-12-24 10:56:08
问题 I've successfully connected to a remote IBM i DB2 database (AS400) from my local Windows PC via PHP. I'm using the IBM Data Server Client in conjunction with the db2_* functions in PHP. The problem I'm having is that despite my library list being set properly, it is not being used for unqualified table names. Instead it uses the current user name as the library. However, when I qualify the table names everything works like a charm. I've confirmed that my library list is actually changing when

Where does Squirrel SQL store its auto correct entries?

旧街凉风 提交于 2019-12-24 10:21:58
问题 I use Squirrel SQL as my goto SQL editor for DB2 for iSeries, and one feature I love is the autocorrect. I enter shortcuts into the editor like ssf and "select * from" pops up. I know it's possible to add entries to the library one row at a time, but how can I add multiple entries at once? I understand it could be an in-depth editing of resource files, and I'm comfortable enough with Java to make the edit but not find the actual resource. The bookmarks feature doesn't suit my needs for this,

very large fields in As400 ISeries database

拜拜、爱过 提交于 2019-12-24 09:35:42
问题 I would like to save a large XML string (possibly longer than 32K or 64K) into an AS400 file field. Either DDS or SQL files would be OK. Example of SQL file below. CREATE TABLE MYLIB/PRODUCT (PRODCODE DEC (5 ) NOT NULL WITH DEFAULT, PRODDESC CHAR (30 ) NOT NULL WITH DEFAULT, LONGDESC CLOB (70K ) ALLOCATE(1000) NOT NULL WITH DEFAULT) We would use RPGLE to read and write to fields. The goal is to then pull out data via ODBC connection on a client side. AS400 character fields seem to have 32K
