Sql query to grant TRUNCATE permission to a table

Need help to write sql query to grant TRUNCATE permission to a table

sujnan wrote:
Need help to write sql query to grant TRUNCATE permission to a tableThis would require DROP ANY TABLE privilege.
However, this is a rather powerful privilege and should not be granted to non admin users.
Alternatively you can create a stored procedure in table owner's schema which would truncate specified table.
Grant execute rights on this SP only to required users.
See an example below:
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1458414958491
You could(rather should) put in more validations in this SP to prevent users from truncating tables that they are not supposed to.

Can we implement the custom sql query in CR for joining the two tables

Hi All,
Is there anyway to implement the custom sql query in CR for joining the two tables?
My requirement here is I need to write sql logics for joining the two tables...
Thanks,

In the Database Expert, expand the Create New Connection folder and browse the subfolders to locate your data source.
Log on to your data source if necessary.
Under your data source, double-click the Add Command node.
In the Add Command to Report dialog box, enter an appropriate query/command for the data source you have opened.
For example:
SELECT
 Customer.`Customer ID`,
 Customer.`Customer Name`,
 Customer.`Last Year's Sales`,
 Customer.`Region`,
 Customer.`Country`,
 Orders.`Order Amount`,
 Orders.`Customer ID`,
 Orders.`Order Date`
FROM
 Customer Customer INNER JOIN Orders Orders ON
 Customer.`Customer ID` = Orders.`Customer ID`
WHERE
 (Customer.`Country` = 'USA' OR
 Customer.`Country` = 'Canada') AND
 Customer.`Last Year's Sales` < 10000.
ORDER BY
 Customer.`Country` ASC,
 Customer.`Region` ASC
Note: The use of double or single quotes (and other SQL syntax) is determined by the database driver used by your report. You must, however, manually add the quotes and other elements of the syntax as you create the command.
Optionally, you can create a parameter for your command by clicking Create and entering information in the Command Parameter dialog box.
For more information about creating parameters, see To create a parameter for a command object.
Click OK.
You are returned to the Report Designer. In the Field Explorer, under Database Fields, a Command table appears listing the database fields you specified.
Note:
To construct the virtual table from your Command, the command must be executed once. If the command has parameters, you will be prompted to enter values for each one.
By default, your command is called Command. You can change its alias by selecting it and pressing F2.

PLEASE SEND ME SQL query to list ALL CONSTRAINTS ON EMPLOYEES TABLE FROM OU

PLEASE SEND ME SQL query to list ALL CONSTRAINTS ON EMPLOYEES TABLE FROM OUTSIDE PP SCHEMA INCLUDING SCHEMA NAME AND CONSTraint NAME

I think you are looking for below query :
SQL> SHOW USER;
USER is "SCOTT"
SQL> select owner,constraint_name,constraint_type,table_name,r_owner,r_constraint_name
2    from all_constraints
3    where constraint_type='R'

1 row selected.Means, TEST1 user is having a constraint ERL_EMP_FK_1 on his table EMPLOYEE. Which is using PK_EMP (primary key of SCOTT user's 'EMP' [in the query])

Help Required -- Can we use SQL Query to READ data from SAP MDM Tables

Hi All,
Please help.........
Can we use SQL Query to READ(No Creation/Updation/Deletion just Read) Data from SAP MDM tables directly, without using MDM Syndicator.
Or direct SQL access to SAP MDM tables is not possible. Only through MDM Syndicator can we export data.
Thanks in Advance
Regards

All the tables you create in Repository comes under A2i_CM_Tables in Database named as your repository name. So the tables names are fields of table A2i_CM_Tables. Now i tried it but cant make it.
Now, I dont think its possible to extract all fields in tables and there values using select query. May be pure sql guy can do that or not.
But there is no relation of data extraction and syndicator. Data is viewed in Data Manager. and you can also store data in a file from DM also.

Excel ADODB Sql Query Execution taking hours when manipulate excel tables

Hello All
I have 28000 records with 8 column in an sheet. When I convert the sheet into ADODB database and copy to new
excel using below code it is executing in less than a min
Set Tables_conn_obj = New ADODB.Connection
Tables_conn_str = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Table_Filename & ";Extended Properties=""Excel 12.0;ReadOnly=False;HDR = Yes;IMEX=1"""
Tables_conn_obj.Open Tables_conn_str
First_Temp_sqlqry = "Select * INTO [Excel 12.0;DATABASE=C:\Prod Validation\Database\Second Acat Table.xlsb].[Sheet1] Table [first - Table$];" Tables_conn_obj.Execute First_Temp_sqlqry
But when I change the query to manipulate one column in current table based on another table in the same excel
and try to copy the results in another excel, it is taking more than one hour.. why it is taking this much time when both the query results returns the same number of rows and column. I almost spend one week and still not able to resolve this issue.
Even I tried copyfromrecordset, getrows(), getstring(), Looping each recordset fields options all of them taking
same amount of time. Why there is huge difference in execution time.
Important note: Without into statement even below query is executing in few seconds.

Hi Fei,
Thank you so much for the reply post. I just executed the same above SQL without INTO Statement and assigned the SQL result to ADODB recordset as below. If the time difference is due to the SQL query then below statements also should execute for hours
right, but it gets executed in seconds. But to copy the recordset to excel again it is taking hours. I tried copyfromrecordset,
getrows(), getstring(), Looping each recordset fields options and all of them taking same amount of time. Please let me know there is delay in time for this much small data
Even I tried to typecast all columns to double, string in SQL and still the execution time is not reduced.

Need of SQL query in selecting distinct values from two tables

hi,
I need a query for selecting distinct values from two tables with one condition.
for eg:
there are two tables a & b.
in table a there are values like age,sex,name,empno and in table b valuses are such as age,salary,DOJ,empno.
here what i need is with the help of empno as unique field,i need to select distinct values from two tables (ie) except age.
can anybody please help me.
Thanks in advance,
Ratheesh

Not sure what you mean either, but perhaps this will start a dialog:
SELECT DISTINCT a.empno,
                a.name,
                a.sex,
                b.salary,
                b.doj
FROM    a,
        b
WHERE   a.empno = b.empno;Greg

Populating item using a sql query based on other item of diff table

Hi,
It would be great if someone could help.
I have two items on my form page .
My first item P1_sub_prog is of select list with submit, it fetches values from table prog "mv_cap_prog_subprog" of the same schema whihc I am using for teh current application.
I want my second item P1_PROGRAM to be populated with value corresponding to my first item value, after being fetched from the same table on the basis of the first item value (P1_SUB_PROG)
Both the item values have a relation.
I tried by creating sql as well as LOV for the second item but its not working.
It displays nulll in the second item field.
While using sql I tried the following query
in the source request of second item i.e P1_PROGRAM
SELECT DISTINCT a.program_id d,a.program_id r FROM
mv_cap_prog_subprog
WHERE SUB_PROGRAM_ID = :P1_sub_prog

Hi,
Search this forum for "cascading select list".
You will find lots of help.

Need suggestions for improving sql query.

Hi,
There is an sql query which loads data into a single table from 80 other tables which are loaded with data from different sites.The sql query to load from these 80 tables into single table is taking almost 40 min everyday with 6-7 million records.
The notation followed
the table is truncated first and then the constraints are disabled.
insert into single table (column1,column2,column3)
( select * from table1
union all
select * from table2
union all
select * from table3
union all
select * from table80);
enable the constraints.
The database is 10.2.0.3.Is there any other way that can be implemented or modified this to get a better response time to load the data faster.
Thanks

A lot of IFs, but
if you have a licence for the partitioning option, and
if the data has some convenient partitioning column - such as a 'site' column which could be used for list partitioning, and
if you don't need the separate tables to exist after you have consolidated the data
if you can create all other necessary constraints on the base tables,
you could:
create main table as empty, but partitioned with 80 empty partitions
exchange partition with table 80 times in a row.

How to build sql query for view object at run time

Hi,
I have a LOV on my form that is created from a view object.
View object is read-only and is created from a SQL query.
SQL query consists of few input parameters and table joins.
My scenario is such that if input parameters are passed, i have to join extra tables, otherwise, only one table can fetch the results I need.
Can anyone please suggest, how I can solve this? I want to build the query for view object at run time based on the values passed to input parameters.
Thanks
Srikanth Addanki

As I understand you want to change the query at run time.
If this is what you want, you can use setQuery Method then use executeQuery.

Help needed in Exporting tables data through SQL query

Hi All,
I need to write a shell script(ksh) to take some of the tables data backup.
The tables list is not static, and those are selecting through dynamic sql
query.
Can any body tell help me how to write the export command to export tables
which are selected dynamically through SQL query.
I tried like this
exp ------ tables = query \" select empno from emp where ename\= \'SSS\' \"
but its throws the following error
EXP-00035: QUERY parameter valid only for table mode exports
Thanks in advance,

Hi,
You can dynamically generate parameter file for export utility using shell script. This export parameter file can contain any table list you want every time. Then simply run the command
$ exp parfile=myfile.txt

as you can see from the above data (5TH COLUMN), i have mentioned the
existance of each player_id in each match prior to the current_match_id
since match_id = 1 is the 1st match in the table so no player_id comes in the
table before match number 1.
In match number 2 , player_id = 1278 was also present in match_id = 1 so
thats why Number_OF_OCCURENCES = 1 for player_id = 1278 in match_id = 2
and so on..
same is the case with 'RUNS' column but here RUNS are the SUM of each
player_id's 'RUNS' before the current match
Note: if some player_id does not exist in the table before the current
match_ID then the query should return zero for that player_id ( as in 4th and
5th columns of no_of_occurances and sum(runs) respectively)
for example: in above data
MATCH_ID TEAM_ID PLayer_ID RUNS NO_OF_OCCURENCES SUM(RUNS)
 BEFORE_THIS_MATCH BEFORE_THIS_MATCH
 FOR_THIS_PLAYER_ID FOR_THIS_PLAYER_ID

I hope this will clear my problem
i would be extremely grateful if someone helps me out??
here is sample ddl of the above data
create table t

TEAM_ID NUMBER(4),
PLAYER_ID NUMBER(4),
RUNS NUMBER(3))

Result of an SQL query as a Column name of another query

Hi Friends,
Can we use a result of a SQL Query as a column name of another table to retrieve data. If so please help me.
For eg :
I have a table where is store numbers;
select col1 from table1 where col1='5';
and i have another table where .. this value of col is a column name..
select ( select col1 from table1 where col1='5') from table2;
Thanks in advance.

Thanks in advance.Do you really mean that?
select col1 from table1 where col1='5';That query will always return either '5' or nothing. Whatever you're trying to accomplish with that, you can do with an EXISTS query.
Perhaps you meant to reference two different columns in that query:
select col1 from table1 where col2='5';In that case, sorry, no, you can't do that without resorting to dynamic SQL.
If the same column is used throughout the query (but could change every time you run the query), then the dynamic SQL might be pretty easy. In SQL*Plus, for example, you could use substitution variables, defined in another query at run-time.
If there are only a few possible values that the sub-query could possibly return, and you know what they all are, then you can fake a dynamic query like this:
SELECT     CASE     ( SELECT col1
            FROM       table1
            WHERE       col2     = '5'
          WHEN 'BONUS'     THEN bonus
          WHEN 'COMM'     THEN comm
          WHEN 'SAL'     THEN sal
     END     AS col1
FROM     table2
;Sorry to give such a vague answer, but it's the best I can do with the information I have.
It would help if you posted a little sample data (CREATE TABLE and INSERT statments for both tables), and the results you want to get from that data. If you want to pass a parameter to the query, give the results you want for a couple of different parameters.
