Column name completion?

Hello,
Is column name completion available in the SQL editor? In other products you can usually type "select * from footable a where a." and it lists all columns in the table. At least it doesn't seem to be enabled by default and I didn't find anything in preferences
Nice look and overall feel in general.
Edit: it seems to work on "footable.". It would be nice to have it on aliases also.

It looks like autocomplete is broken in 897. When I type "select * from jfuda.dept." the cursor turns to an hour glass like its about to do something and then ... nothing ... no popup. (My Code Insight: Completion preferences are all checked, btw.)
Also, re. lower vs upper case, personally I prefer lower case, but I'm sure others would prefer upper case. How about inspecting the preceeding alias or table name and using whatever format it was typed in? For example, if I type "jfuda.dept.", I'd see a pick list with lower case values. If I type "JFUDA.DEPT.", an uppercase list of values would appear.

Issue in Column NAMES Printing in SQLPLUS

Hi All,
I am connecting to 2 databases through a 10.1.0.4.2 Version of SQLPLUS.
1st Database runs with - 10.2.0.4 Patchset
2nd Database runs with - 10.2.0.1.0 Patchset
From both the Databases we are running a long query with columns using Decode funtions. We are not able to see the column names completely in the 1st DB i.e 10.2.0.4 Patchset. Whereas in 2nd DB - Version 10.2.0.1.0 - Its working properly. I am not sure whether here DB version is the problem.
This is the query i am firing from both DB's. Here in the 1st column with decode function doesnt prints the column heading in SQLPLUS.
SELECT DECODE('ENG','ENG',A.PC_DESC,A.PC_DESC_BL)
FROM PCOM_CODES A, PCOM_CODES_APPL_CODES B
WHERE CAC_TYPE = 'VEH_CC_TYPE'
AND A.PC_TYPE = CAC_PC_TYPE_2
AND A.PC_CODE = B.CAC_PC_CODE_2
AND ROWNUM < =2
DECODE('ENG','ENG',A.PC_DESC,A.PC_DESC_BL) - This is the column name which doesnt prints properly in a 10.2.0.4.0 Database.
Is there any specific User specific or DB specific setting for such issues. We dont want to use any alias column names for specific purpose to be handled with that column name.
We have already tried out the following.
1) All SQLPLUS environment variables like SET SERVEROUT ON SIZE etc.
2) In the same PC where DB is installed.
3) Checked even if its a Data issue but really not.
4) We cannot set any alias column for this due to functional restrictions.
I appreciate a quick response from the forum users on this issue.
Thanks in advance.

check this out.
I still believe it is a formatting issue.

Unable to reorder/change column names on interactive single row view

I have created an interactive report and grouped my columns to display nicely in a single row view report. However, once I initially add the columns to a group, I am unable to reorder them. I can move them up and down the list, but the changes don't save. Also, I have gone through column by column and unchecked the box that says Use Same Text for Single Row View and expanded the column name. However, the single row view still displays what is in the master report. I've tried closing out my browser completely and reopening, but I am still not seeing my changes. Any suggestions?

I also just stumbled about the "Use Same Text for Single Row View" option actually doing nothing - in Single Row View I still get the label text from "Column Heading", no matter what I enter in "Single Row View Label".
I had to adjust a column width using a span tag in the heading (as this seems to be the only way to do that - any other suggestions I found adding style information to the region header had no effect), and now that tag is displayed in the Single Row View label.
I can live with that for now, but it's not really nice.
Is this a known bug? Didn't find anything else in the forum regarding this problem so far.

How can i export the data to excel which has 2 tables with same number of columns & column names?

Hi everyone, again landed up with a problem.
After trying a lot to do it myself, finally decided to post here..
I have created a form in form builder 6i, in which on clicking a button the data gets exported to excel sheet.
It is working fine with a single table. The problem now is that i am unable to do the same with 2 tables.
Because both the tables have same number of columns & column names.
Below are 2 tables with column names:
Table-1 (MONTHLY_PART_1)
Table-2 (MONTHLY_PART_2)
SL_NO
SL_NO
COMP
COMP
DUE_DATE
DUE_DATE
U-1
U-1
U-2
U-2
U-4
U-4
U-20
U-20
U-25
U-25
Since both the tables have same column names, I'm getting the following error :
Error 402 at line 103, column 4
alias required in SELECT list of cursor to avoid duplicate column names.
So How can i export the data to excel which has 2 tables with same number of columns & column names?
Should i paste the code? Should i post this query in 'SQL and PL/SQL' Forum?
Help me with this please.
Thank You.

You'll have to *alias* your columns, not prefix it with the table names:

Strange behavior in BI Publisher with long column names from BI Answers

Hello all!
I have created a BI Answers request with few calculated columns in form of
case when <condition> then <value if true> else <value if false> end
Then in BI Publisher Desktop designed a report ttemplate based on saved BI Answers request and noticed that for calculated columns their names look strange:
CASEWHEN_<condition>THEN...ELSE..._...END__
Some of the column names are about 100 characters long.
After running the report from Word found that for these "long length named columns" there's no data in the output.
Do someone else experience the same? Any workarounds?
Regards,
mr.maverick

This is because the length for the formula is restricted in publisher. you have to either reduce the size of the column name in answers or change the formula. another workaround is completely pasting the formula directly in the word template instead of placing the formula inside the form field. you can add maximum of 300 characters i guess. you can edit the formula for the form field in the form field options formuals menu.

Please help me I am not seeing Database table column names in field explorer view

Hi,
I am developing a crystal report using eclipse and sql server. After creating connection, when i drag and drop tables, The table name and its columns should apper in field explorer view. Then we drag the columns onto crystal report. Unfortunately I am just seeing only table names but not column names in field explorer view. Could anyone help me?
After downloading eclipse I have plugged in the crystal report using the following instructions
1. Click on the Help menu, and then Software Updates > Find and Install... to open the Install/Update wizard.
2. Select Search for new features to install and click Next.
3. Click the New Remote Site button. This will launch the New Update Site wizard

Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
If you are using SQL Server 2012/2014, then you can use
sys.dm_exec_describe_first_result_set (Transact-SQL) to gte the informations.

How to get the column name and table name from xml file

I have one XML file, I generated xsd file from that xml file but the problem is i dont know table name and column name. So my question is how can I retrieve the data from that xml file?

Here's an example using binary XML storage (instead of Object-Relational storage as described in the article).
begin
dbms_xmlschema.registerSchema(
    schemaURL       => 'my_schema.xsd'
, schemaDoc       => xmltype(bfilename('TEST_DIR','my_schema.xsd'), nls_charset_id('AL32UTF8'))
, local           => true
, genTypes        => false
, genTables       => true
, enableHierarchy => dbms_xmlschema.ENABLE_HIERARCHY_CONTENTS
, options         => dbms_xmlschema.REGISTER_BINARYXML
end;
genTables => true : means that a default schema-based XMLType table will be created during registration.
enableHierarchy => dbms_xmlschema.ENABLE_HIERARCHY_CONTENTS : indicates that a repository resource conforming to the schema will be automatically stored in the default table.
If the schema is not annotated, the name of the default table is system-generated but derived from the root element name :
SQL> select table_name
2 from user_xml_tables
3 where xmlschema = 'my_schema.xsd'
4 and element_name = 'employee';
TABLE_NAME
employee1121_TAB
(warning : the name is case-sensitive)
To annotate the schema and control the naming, modify the content to :
<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb">
<xs:element name="employee" xdb:defaultTable="EMPLOYEE_XML">
    <xs:complexType>
Next step : create a resource, or just directly insert an XML document into the table.
Example of creating a resource :
declare
res boolean;
doc xmltype := xmltype(
'<employee>
<details>
    <emp_id>1</emp_id>
    <emp_name>SMITH</emp_name>
    <emp_age>40</emp_age>
    <emp_dept>10</emp_dept>
</details>
</employee>'
begin
res := dbms_xdb.CreateResource(
           abspath   => '/public/test.xml'
         , data      => doc
         , schemaurl => 'my_schema.xsd'
         , elem      => 'employee'
end;
The resource has to be schema-based so that the default storage mechanism is triggered.
It could also be achieved if the document possesses an xsi:noNamespaceSchemaLocation attribute :
SQL> declare
2
3    res boolean;
4    doc xmltype := xmltype(
5 '<employee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
6             xsi:noNamespaceSchemaLocation="my_schema.xsd">
7    <details>
8      <emp_id>1</emp_id>
9      <emp_name>SMITH</emp_name>
10      <emp_age>40</emp_age>
11      <emp_dept>10</emp_dept>
12    </details>
13   </employee>'
14   );
15
16 begin
17    res := dbms_xdb.CreateResource(
18             abspath   => '/public/test.xml'
19           , data      => doc
20           );
21 end;
22 /

I'm attepting to use DBMS_SQL to perform similar instructions.
Is it possible?

Hi Pedro
You need to use DBMS_SQL here because you don't know how many columns your query is going to have before runtime. There are functions in DBMS_SQL to get information about the columns in your query - all this does is get the name.

How do i change column names in oracle model?

Hi,
I am performing a migration from SQL SERVER 7.0 to Oracle 8.1.7.
I have tables that have tables in SQL SERVER with column names
that are "TYPE" and "BODY".(These are generally TEXT datatype
columns that need to be converted to LONG in Oracle.We need
these to be LONG datatype in Oracle because of an application we
are using. LOBS cannot be allowed)
The migration utility renames these columns as "TYPE_"
and "BODY_" and creates the tables in the Oracle Database.
I need to have these tables in Oracle with the same column names
viz. "TYPE" and "BODY" .
I can create new tables in Oracle with the column names "TYPE"
and "BODY" but cannot change the options in the migration
workbench for this.
Is there any option or any workaround I can use to change the
column names in the Oracle model?or set the options so that the
Oracle model tables donot modify these column names?
Thanks in advance for all the help.
Mandar

The words 'TYPE' and 'BODY' are reserved Oracle words. Its best
to go along with what the workbench has suggested. If you have
to keep the original names of the columns trying wrapping double
quotes around them after the data migration is complete. This
may cause a case sensitivity or referential problem later on
though.

If variable name is the same as the column name in procedure ?

If variable name is the same as the column name in procedure , What should i do?
For Example :
CREATE OR REPLACE PROCEDURE "TEST_PROC" (MIN_SALARY in UMBER)
as
begin
INSERT INTO TEST SELECT JOB_ID,MIN_SALARY FROM JOBS WHERE MIN_SALARY = MIN_SALARY;
end;

You could follow a better naming convention and have the parameters to the procedures named in a way so as not to be confused with column names.
You could prefix the variable names with the name of the procedure they appear in but then what if your have procedure names same as table names?
SQL> create or replace procedure test_proc(sal in number) is
2    cnt number ;
3 begin
4    select count(*) into cnt from scott.emp where scott.emp.sal = test_proc.sal ;
5    dbms_output.put_line('cnt='||cnt) ;
6 end ;
7 /
Procedure created.
SQL> set serveroutput on
SQL> exec test_proc(800) ;
cnt=1
PL/SQL procedure successfully completed.
SQL>If you search you can find several posts here itself on naming convention to avoid such issues in first place.

Using dynamic column name in datagrid selectedItems

Hi
I have a datagrid loaded with 2 columns. Allowmultiselect is turned on.
Based on the values selected at run time, I get the corresponding selected column name and its values and shown it on HTML screen.
// grp is datagrid
// dgrcl is a data grid column
// selflds is an array which has 0,1,2,3 values
//selflds[0] = name,selflds[1]=age
for (var l:int=0; l<grp.columnCount; l++)
dgrcl =grp.columns[l];
selflds[l] = dgrcl.dataField;
// srhVals will have only one selected value at any point
// getting the corresponding selected column name and its value
var srhVals:String;
srhVals = String(grp.selectedItem[selflds[1]]);
I am trying to achieve the above selection instead by .selectedItems somthing like this below. By doing like this, I will get all the selected items but not only one. If i try below syntax, i get error. Any one has ideas on how to do.
srhVals = String(grp.selectedItems.selflds[1]);

Hi
I got my mistake, there should be no dot operator after selectedItems;
I got a solution - it goes like this:
for(var g:int=0;g<grp.selectedItems.length;g++)
srhVals = srhVals + String(grp.selectedItems[g][selflds[1]]);
So the complete scenario is like this:
Datagrid:
Name      Age
a               20
b               30
c               40
d               50
I am selecting b,d in UI. At run time, I get programatically the selecteditem column name as "Name", loop through the selecteditems and store the value in srhVals as b,d.
b,d will be finally shown in UI.

Using column number inplace of column name in SQL Select statement

Is there a way to run sql select statements with column numbers in
place of column names?
Current SQL
select AddressId,Name,City from AddressIs this possible
select 1,2,5 from AddressThanks in Advance

user10962462 wrote:
well, ok, it's not possible with SQL, but how about PL/SQL?As mentioned, using DBMS_SQL you can only really use positional notation... and you can also use those positions to get the other information such as what the column is called, what it's datatype is etc.
