Bulk Insert for more than 50 columns of one table to another.
Hi all
I have two Source and target tables that are the same in structure, and I need the Source Table Insert into the target Table.
Source and the target Table is to have about 60 columns. And Volumn of data in the Source Table is about 1 Cr.
Previously, someone wrote the Simple insertion as
INSERT INTO TARGET_TBL (C1, C2, C3, C4... C60)
(SELECT C1, C2, C3, C4... TARGET_TAB C60);
And it will not work for this a large part of the data. Could you please suggest the best approach to do this.
Thanks in advance.
Hello..
This will not work for that much of the data
Tips for use as APPEND... See below link for direct loading
Try the below
ALTER session enable parallel dml.
INSERT / * + append parallel (6) * / INTO TARGET_TBL (C1, C2, C3, C4... C60)
(SELECT C1, C2, C3, C4... TARGET_TAB C60);

How to have more than 20 columns in a table in the form of adobe?
I see that there is limitaion of not having more than 20 columns in my table in the form of adobe, is it possible that I can have more than 20 columns in a table in the form of adobe in landscape mode.
Hello
Which applies only to the Table Wizard. Once the table is placed on the page, you can add columns manually in the menu or by right-clicking a column.
You can also use fields in a repeating subform (rather than the object of the table).
Good luck

Correspondence of the columns from one table to another
I have a database column that contains the name of a person. I have another table that has a column that contains the names separated by a comma.
I want to match records where all records of two columns have a corresponding name. I tried this:
< cfquery name = "MyQuery" datasource = "myds" >
SELECT *.
OF TBL_A
WHERE TBL_A.customername IN (#DifferentQuery.ListOfNames #)
< / cfquery >
Everything that I try results in only get a recording. Basically, I want to get all records from a table where one of its columns contains the name of a column in another table.
It's a many-to-many relationship. That is to say an editorial can be linked to many ads, and vice versa. He is best represented with three tables. Such as:
Table: [Editorial] column: [EditorialID (PK), EditorialText,...]
Table: Columns of the [advertiser]: [AdvertiserID (PK), AdvertiserName]
Table: [Editorial_Advertisers] columns: [EditorialID, AdvertiserID]
The name of the advertiser throw himself into a column...
my client can decide which ads get related to which editorials
The third table stores the relationship between ads and editorials. So instead of storing a list of advertisers, you need to insert record for each EditorialID + AdvertiserID combination. You can then use joins to retrieve all the advertisements for EditorialID 123.
SELECT a.AdvertiserName FROM Editorial_Advertiser ea INNER JOIN Advertiser a ON ea.AdvertiserID = a.AdvertiserID WHERE ea.EditorialID = 123

transfer of some columns from one table to another table...?
I had 2 table... .one is PAYMAST n other TBL... In PEXMAST & TBL 10 collar each, I had and I want to transfer 4 columns of TBL to PEXMAST...
How do I do this. ???A table must be regarded as line and column.
When you say a column, it should be associated with a line.
Here is an example
Let's say I have two table T1 (ID, NAME) and T2 (ID, Name1)
Now if I say I want to spend for T2 T1 name1, what I will do?
1 create a column name1 in T1.
alter table t1 add name1 varchar2(50)
2. put up-to-date T1 by joining T1.ID and T2.ID like that.
update t1 set t1.name1 = (select t2.name1 from t2 where t2.id = t1.id)
As you can see you need a column ID to define the relationships between the two table T1 and T2. If you have one, you can do the same with yours.

Spry framework all related examples are available here: http://adobe.github.com/Spry/samples/ you can take a look.
On a sidenote, Spry has been deprecated and is no longer officially supported by Adobe: http://blogs.adobe.com/dreamweaver/2012/08/update-on-adobe-spry-framework-availability.htm l
I would recommend that you switch to a jQuery library to your other needs.

To open the Options menu system recovery using a system repair disc or a Windows 7 installation disc
If your system is damaged and cannot access the menu system on your computer Recovery Options, you can access it using the Windows 7 installation disc or a system repair disc previously.
To use this method, you need to restart (boot) your computer using the disk.
a. Insert the disc.
b. restart your computer using the power button on the computer.
c. If prompted, press any key to start Windows from the installation disc.
o If your computer is not configured to start from a CD or a DVD, see the documentation provided with your computer.
d. choose your language settings, and then click Next.

f. Select the Windows installation you want to repair, and then click Next.
g. in the System Recovery Options menu, click a tool to open it and then choose the system restore and check.
If we are able to boot to the desktop now, I would ask you install the updates one by one andcheck the update is at the origin of the conflict.I hope this helps.Kind regards

Phone has been "redevelopment" iCloud drive for more than a day now
In parameters, iCloud Drive was churning "valorisation" for more than a day now. Did not help restart the phone. iPhone 6 s, iOS 10.0.2.
Thank you!
What kind of "reboot", you have? What was this - restart your iPhone, iPad or iPod touch - Apple Support? If you did, and it did not work, try switching iCloud drive, power switch (settings > iCloud > iCloud drive). If this does not work, try to connect to your iCloud account and reconnect.

Whenever I try to open the App Store it will remain open for more than 30 seconds before the close. Or it just restarts as soon as a home screen scroll above him. I can't keep it open long enough to even download an application.
Hello monorayfromportland,
If you are unable to connect to the iTunes Store on your Apple TV, take a look at the troubleshooting steps below:
If you cannot connect to the iTunes Store
If you cannot connect to the iTunes Store on your Apple TV (4th generation):
- Make sure that your date and time are correct. Go to settings > general > Date and time.
- Check if your Apple TV software is up-to-date. To check the updates, select settings > system > software updates > software update.
- Make sure you have an active network connection. Go to settings > network.
- Check to see if other devices, such as computers or tablets, can connect to Wi - Fi and access to the Internet.
- Reset the wireless router by turning and then again.
Take care.

Introduction to iCloud but "glued" for more than 12 hours
I am new to icloud and try to put up my pictures in icloud.
in the Photos on my imac, he says it's "uploading 11 983 points", but he's been stuck like that for more than 12 hours.
If I click on icloud in system preferences, it is also stuck and will not let me click on anything whatsoever.
What should I do now?
The first part in the photos is not uncommon, the initial download may take days and seems to stall for long periods of time. The second part on the system preferences is unusual, have you tried to restart the Mac yet.
