Format date to string

半腔热情 提交于 2019-12-03 16:47:37
I'm trying to format a db2 date into a string as "YYYY/MM/DD". The best I got so far is: SELECT CAST(YEAR(MYDATE) AS VARCHAR(4)) || '/' || CAST(MONTH(MYDATE) AS VARCHAR(2)) || '/' || RIGHT('00' || CAST(DAY(MYDATE) AS VARCHAR(2)), 2) FROM MYCALENDAR Is there a better, terser way to do this? ps: Toying around with locales is not an option. According to the IBM documentation the following should work: SELECT VARCHAR_FORMAT(MYDATE, 'YYYY/MM/DD') FROM MYCALENDAR; 来源: https://stackoverflow.com/questions/9083121/format-date-to-string

Weblogic: Call DB2 stored procedure without schema name (property currentSchema)

人盡茶涼 提交于 2019-12-03 14:56:06
I have a Java application that runs on Weblogic. The application needs to access a stored procedure in a DB2 data base, therefore a JDBC data source is configured and accessed by its JNDI name. Data source: ClassDriver: com.ibm.db2.jcc.DB2Driver Properties: user=MYUSER DatabaseName=MYDB The following example works as expected. Context env = null; DataSource pool = null; Hashtable ht = new Hashtable(); ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); ht.put(Context.PROVIDER_URL,"t3://myserver:7777"); env = new InitialContext(ht); pool = (DataSource) env.lookup(

How Do I Use Case Statement Column In Group By

▼魔方 西西 提交于 2019-12-03 13:19:27
问题 As stated by the question, I'm trying to formulate a query that has a case statement in the column results, and then I want to include that column in the query's group by statement. To give a concrete example, here is all little of what my query looks like: SELECT SOME_TABLE_ALIAS.COLUMN1, OTHER_TABLE_ALIAS.COLUMN2, CASE WHEN SOME_TABLE_ALIAS.COLUMN3 IS NOT NULL THEN 'A' ELSE 'B' END AS CASE_COLUMN FROM SOME_TABLE SOME_TABLE_ALIAS ... (other table joins and where clauses) GROUP BY SOME_TABLE

DB2: Won't Allow “NULL” column?

邮差的信 提交于 2019-12-03 11:43:16
问题 Part of a complex query that our app is running contains the lines: ...(inner query) SELECT ... NULL as column_A, NULL as column_B, ... FROM ... This syntax of creating columns with null values is not allowed in DB2 altough it is totally OK in MSSQL and Oracle DBs. Technically I can change it to: '' as column_A, '' as column_B, But this doesn't have exactly the same meaning and can damage our calculation results. How can I create columns with null values in DB2 using other syntax?? 回答1: DB2

How to do a safe “SELECT FOR UPDATE” with a WHERE condition over multiple tables on a DB2?

ε祈祈猫儿з 提交于 2019-12-03 11:33:54
Problem On a DB2 (version 9.5) the SQL statement SELECT o.Id FROM Table1 o, Table2 x WHERE [...] FOR UPDATE WITH RR gives me the error message SQLSTATE=42829 (The FOR UPDATE clause is not allowed because the table specified by the cursor cannot be modified). Additional info I need to specify WITH RR , because I'm running on isolation level READ_COMMITTED , but I need my query to block while there is another process running the same query. Solution so far... If I instead query like this: SELECT t.Id FROM Table t WHERE t.Id IN ( SELECT o.Id FROM Table1 o, Table2 x WHERE [...] ) FOR UPDATE WITH
