问题 I want to make java code that does only this: Login to the 'xe' connection in Oracle 11g database. That's all. How can do it ? EDIT: yes, i was using JDBC, but unable to login to that connection. My url is jdbc:oracle:thin:@//localhost:1521/xe , username = sys and password = 123456 for the xe or sys connection. Then why can't i login to that connection ?

问题 This question already has an answer here : Use of LIKE clause in sql prepared statement, spring, SimpleJDBCTemplate (1 answer) Closed 3 years ago . ps=con.prepareStatement("select * from REGISTER inner join ORGAN on REGISTER.PATIENTID=ORGAN.PATIENTID where ORGAN.ORGAN LIKE ?"); ps.setString(1,"'%"+o.getOrgan()+"%'"); I executed the query in SQL Developer which works fine, but in DAO class it is not returning any result set. 回答1: Use ps.setString(1, "%" + o.getOrgan() + "%"); Note the absence

问题 I'm using a query where a part of it gets the top 3 of a certain column. It creates a distinct subquery of the column, limited by 3 number of rows, and then filters those rows to the main query to do the top 3. WITH subquery AS ( SELECT col FROM ( SELECT DISTINCT col FROM tbl ) WHERE ROWNUM <= 3 ) SELECT col FROM tbl WHERE tbl.col = subquery.col So the original table is like this: col ----- a a a b b b c d d e f f f f And the query returns the top 3 of the column (not the top 3 rows which

问题 How do I return a rowset consisting of the last four years based on the current date? If this query runs on 12/31/2010 it should return: 2007 2008 2009 2010 But if it is run on 1/1/2011 it should return: 2008 2009 2010 2011 Here's what I started with, two queries that return the starting year. I prefer the second as converting to string feels a bit dirty to me. SELECT TO_CHAR(TRUNC(sysdate, 'YY') - INTERVAL '3' YEAR, 'YYYY') FROM DUAL; SELECT EXTRACT (YEAR FROM sysdate) - 3 FROM DUAL; But I

问题 In an Access 2013 Report I connect to an Oracle DB View via a Linked Table. One View field is of type BLOB and holds images that have been previously stored there. In my Access Report the linked table has a field (named BILD_INHALT) of type "OLE Object" that maps to the BLOB field in Oracle DB. In the report view, I created an "Image" field (named MST_Image) has to load the image and it is initialized in the following way: If Len(RS![BILD_INHALT]) > 0 Then Me.MST_Image.PictureData = RS![BILD

问题 I need to extract data from a SAP ABAP system in a format that can then be loaded into an Oracle database (xlsx,csv,dmp.. etc) Once the data is extracted I'll use Pentaho to upload it into the Oracle database. Is there a way to extract the data from SAP? I will also need to automate it (the extraction) but that is not too much of a problem right now, I can figure/worry about that part later. If it is not possible to do so, an explanation why would be helpful! 回答1: You have a number of options
