问题 I've defined this trigger: CREATE TRIGGER actualizarSaldoIngreso BEFORE INSERT ON Ingreso FOR EACH ROW MODE DB2SQL BEGIN ATOMIC UPDATE Cliente SET Nombre = 'Juan' WHERE DNI = '87366034M'; END; But DB2 returns this error: An unexpected token "END-OF-STATEMENT" was found following "RE DNI = '87366034M'".

问题 We have installed Data Studio 4.1.0.0 Client to access the data that is stored in DB2. We have installed DB2 11.1 64bit on our PC which has a Windows 7 64 bit.

问题 I'm totally confused about how to get this query done. How to achieve this query with no big performance impact (if table contains thousands rows) ? Please advice!

问题 How can I find the difference between two dates in DB2 (excluding weekends)? Are there any functions that will do this in DB2? Or do I need to write a query myself? 回答1: There is AFAIK no such function. It is however easy to write a query that calculates this: with cal(d) as ( values date('2015-01-01') -- start_date union all select d + 1 day from cal where d < '2015-01-15' -- end_date ) select count(case when dayofweek(d) between 2 and 6 then 1 end) from cal; If you do a lot of these kind of

问题 I have a table in DB2 with column type CLOB, I would like to convert this to a BLOB type. My approach here is to create a new column with BLOB type, copy all the data from CLOB column to BLOB column, drop the CLOB column and rename the BLOB column. However, I am not sure how to do the second step i.e. update data from CLOB column to BLOB column. What is the function of DB2 that will let me do this? Thanks in advance. 回答1: As you are on Db2-LUW V11.1 and AIX, you can consider using the stored

问题 I have following OpenJPA query (over db2 database): Select number from Number number where number.uuid = :uuid Column uuid defined as VARCHAR FOR BIT DATA(16).

问题 is there a way to export the "CREATE PACKAGES" statements with db2look functionality? I try with the different options but couldn't get the CREATE PACKAGES statements. The reason why I want that is because we copy a PROD db to a TEST DB and the schema for 2 PACKAGES changes name so I just want to recreate them in the right package. Here is the command I launch: db2look -d DBNAME -a -e -z SCHEMA_NAME -l -o OLDSCHEMA.sql 回答1: Why do you want to recreate packages, because they are only needed

问题 I have an iSeries table with thousands of rows, and a new numeric/integer column was just added as the table Key. This will basically be a integer id column (1,2,3...). Let's say that I can't make this column an auto-incrementing column. Is there an simple way to assign unique, incremental values to each row without having to loop through each record assigning a value? Perhaps some kind of UPDATE query? 回答1: You can use the RRN scalar function to assign the relative record number: update
