    <p>I am trying to make a view, but I am getting a duplicate column name error. If I run the select query separately, then the query returns a result like:</p> <pre><code>SELECT distinct app.APP_REF_NO, app.APP_STATUS, app.APP_DT, app.ATTEND_STAFF, app.ATTEND_BRANCH, app.PRODUCT_TYPE, cust.CUST_ID, cust.APP_JOINT_T, cust.ID1_TYPE, cust.ID1, cust.ID2_TYPE, cust.ID2, cust.FIRST_NAME, cust.LAST_NAME, cust.FULL_NAME, cust.FULL_NAME_CAP, cust.DOB, fac.FACILITY_NO, fac.PRODUCT_TYPE, fac.PRODUCT_CODE, fac.MAIN_PROD_IND, fac.AMT_APPLIED FROM LOSA_APP app LEFT JOIN LOSA_CUST cust ON cust.APP_REF_NO = app.APP_REF_NO LEFT JOIN LOSA_FACILITIES fac ON fac.APP_REF_NO = app.APP_REF_NO LEFT JOIN OS_CURRENTSTEP STEP ON STEP.REF_ID = app.APP_REF_NO WHERE (app.APP_STATUS ='P' OR app.APP_STATUS ='T' OR ((app.APP_STATUS='R' OR app.APP_STATUS='S') AND STEP.STEP_NAME='011')); </code></pre> <p>This query works fine. But when I try to run it as a view like:</p> <pre><code>CREATE VIEW basit_test1 AS SELECT distinct app.APP_REF_NO, app.APP_STATUS, app.APP_DT, app.ATTEND_STAFF, app.ATTEND_BRANCH, app.PRODUCT_TYPE, cust.CUST_ID, cust.APP_JOINT_T, cust.ID1_TYPE, cust.ID1, cust.ID2_TYPE, cust.ID2, cust.FIRST_NAME, cust.LAST_NAME, cust.FULL_NAME, cust.FULL_NAME_CAP, cust.DOB, fac.FACILITY_NO, fac.PRODUCT_TYPE, fac.PRODUCT_CODE, fac.MAIN_PROD_IND, fac.AMT_APPLIED FROM LOSA_APP app LEFT JOIN LOSA_CUST cust ON cust.APP_REF_NO = app.APP_REF_NO LEFT JOIN LOSA_FACILITIES fac ON fac.APP_REF_NO = app.APP_REF_NO LEFT JOIN OS_CURRENTSTEP STEP ON STEP.REF_ID = app.APP_REF_NO WHERE (app.APP_STATUS ='P' OR app.APP_STATUS ='T' OR ((app.APP_STATUS='R' OR app.APP_STATUS='S') AND STEP.STEP_NAME='011')); </code></pre> <p>Then I get the duplicate column name error. Why am I getting this error?</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
