问题 The Tabular form was created on a classic report with an SQL Query (updateable report). It also has a wizard generated MRU & MRD process And the region source has the following code (written below) which works fine and displays columns as stated below select "ROWID", "EVAL_SR_NO", (SELECT SKILL_DESC FROM TB_RCMI_EVAL_SKILLS WHERE SKILL_ID ="TB_RCMI_CNDT_INTV_EVAL"."EVAL_SKILL_ID" ) as "EVAL_SKILL_ID", "EVAL_SKILL_REMARKS" from "#OWNER#"."TB_RCMI_CNDT_INTV_EVAL" where eval_type='TE'and WF_ID =

问题 I am developing an application which tracks class attendance of students in a school, in Apex. I want to create a page with three level cascading select lists, so the teacher can first select the Semester, then the Subject and then the specific Class of that Subject, so the application returns the Students who are enrolled in that Class.

问题 I'm trying to create a report in Oracle ApEx that displays a list of files, and allows you to download them. The files are being created by an external application and I have full control over where they are placed. Just now I am creating them in a subfolder of the ApEx images directory (C:\oracle\product\11.2.0\dbhome_1\apex\images). However, if I try to link to here, I just get a blank page - I've tried the #WORKSPACE_IMAGES# and #IMAGE_PREFIX# values as the link URL but it doesn't work.

问题 I believe we're moving to Oracle Apex for future development. I've read about Oracle Apex on wikipedia and it's pro and con. It seem to me the con outweigh the pro but maybe I'm wrong. I get the sense that Oracle Apex is for DBA with little or no programing knowledge to setup a web app quickly sort like MS Access for none programmer. If you have Oracle Apex working experience, can you share your thought? From Wikipedia's entry, it doesn't seem like you need to know any programming language at

问题 On button click action "Redirect to URL" I call below script: javascript:var a = window.open('f?p=300:99:&APP_SESSION.::NO:105:PARAM_1,PARAM_2,PARAM_3:&P99_PARAM_1.,P99_PARAM_2,&P99_PARAM_3.'); Is it possible call this from PLSQL in oracle apex application eg. begin //call here //htp.p(?? end; 回答1: You can use APEX_UTIL.REDIRECT_URL for this. Check the documentation. Your pl/sql would then be (bind var syntax :P1_ITEM because it is pl/sql): BEGIN apex_util.redirect_url(p_url => 'f?p=300:99:'|

问题 I work in apex oracle, I have a table with geo-coordinates and objects. When I seal this object, I fill out the form. When I fill out this form, I select an object from the LoV from the "test1" table, also in the form of automatically pulling my location into cells P1_long, and P1_lati.

问题 Looking to throw an error where the value i'm updating is a 'not null' value. For example. In below table, say I wanted to update Paul's lastname with 'Jackson'. The SQL should throw an error to say that the value that is being updated is 'not null'. First Lastname Paul Parkinson Peter null Turkey null As a second part to this question, I'm actually looking to do this in the APEX Express Data Load Wizard. If anyone would know how to modify the update command to do this, it would be greatly
