How to compare two strings in PL/SQL

Hi all
I need to compare two strings, they are equal or not in PL/SQL. Y at - it a function to compare the strings.

Yes, the sign =.

You're after something like:

IF v_string1 = v_string2 THEN
  ...
ELSE
  ...
END IF;

How to compare two lines in PL/SQL? Is there a method I can use to compare their column by column instead?

Any comments would be much appreciated.

By lines I mean, two rows of the same table!

Ah, finally, we get a bit more useful information

and I need to compare the column by column to see if there is a difference between these two rows.

Like this, you mean?

My only concern is the result of this sql. East - reliable? It can really be used to differentiate the two lines? I mean, the result would be the same, as I do with Java?

Not sure what you mean by "reliable"? SQL is not some kind of generator of random result (by derogation from the use of the DBMS_RANDOM package). If you ask him if 1 + 1 = 2, then it will always give you the right answer.

I'm not able to compare two strings in OpenScript

Hello
I'm trying to compare two string in if condition. But it's going through.
My code is:
String PATTERN_TYPE = eval ("{{db. INPUTS_CREATE_REPRICING_PATTERN. PATTERN_TYPE}} ")." ToString();
String REPRICING_TYPE = eval ("{{db. INPUTS_CREATE_REPRICING_PATTERN. REPRICING_TYPE}} ")." ToString();
If (PATTERN_TYPE is 'Absolute')
{
Info ("absolute section");
If (REPRICING_TYPE is "FLAT")
{
Info ("absolute section PLATE");
}
}
Data Bank is to have values like "Absolute" and "FLAT" only if the two if conditions must have passed and the two info should come. But it's not going inside.
Note: I also tried without function toString().
Please advice.
Kind regards
Abhay

Hi Abhay,

Please use below...

World in java, strings are compared with equivalent to...

==tests for equality of references.

.equals()tests for equality of the values.

String PATTERN_TYPE = eval ("{{db. INPUTS_CREATE_REPRICING_PATTERN. PATTERN_TYPE}} ")." ToString();

String REPRICING_TYPE = eval ("{{db. INPUTS_CREATE_REPRICING_PATTERN. REPRICING_TYPE}} ")." ToString();

If (PATTERN_TYPE.equals ("Absolute")

{

Info ("absolute section");

If (REPRICING_TYPE.equals ("FLAT")

{

Info ("absolute section PLATE");

}

How to compare two files in Windows 7 prof 64 bit

I have two files which has several files. I would like to compare the two files and see which folder has more files, and what are their names? How I do that in Windows 7 prof 64 bit? Is useful that I can download?

Hey dude-

Here's the right way to do without external downloads. It looks like a lot at first, but once you have done so, it is very easy. It works in all versions of Windows 7 to 95. For our example, let's assume you're to compare two directories named 'A' and 'B '.

1. run cmd.exe to get a command prompt. (In Windows 7, the powershell will not work for this, FYI.) Then do it again, so that you have two of them opened next to each other.

2. in each window go into the directories you want to compare. (With the help of the 'cd' command. If you're not comfortable with that, then you should probably go with the external utilities, except if you want to learn the tricks of the command prompt.)

3. type ' dir/b > A.txt' in one window and "dir/b > B.txt' in the other." Now you have two text files that list the contents of each directory. The flag/b means stripped, which removes the list down to only the names of files directories.

4. move is the same folder as A.txt B.txt.

5. Type "CF A.txt B.txt". The command "CF" means file to compare. It will spit out a list of the differences between the two files, with an additional line of text above and below each difference, so that you know where they are. For more options on the way in which the output is in the format, type ' fc /? "at the command prompt. You can also pipe the differences in another file using something like ' CF A.txt B.txt > differences.txt'.

Have fun.

How to compare two users (2)

Hi all
11.2.0.1
AIX 6.1
I have two databases (dev & uat) on separate servers with equal facility.
On each database, I created a schema user "batchdba" and gave them same privilege "dba".
But when I import (impdp) the dumpfile output from other databases that encrypted table and with the same command, it runs successfully on DEV but not on the UAT.
How can I compare that privilege is missing from the UAT for the user "batchdba". Or how to compare the privileges granted to these two patterns?
Thank you very much

You can query the following views on the databases to compare the result

dba_tab_privs

dba_role_privs

dba_sys_privs

query these tables with the status RECIPIENT = "BATHCDBA."

Can someone point me in the right direction here of what formula to use for this Xl.

Thank you

This is a forum for Mac OS X technologies, so here's an Applescript solution:
1. Copy-paste the script in the Script Editor
2. Select the cells in columns A and B
3. Command + c to copy to the Clipboard
4. Click on the button "run" in the Script Editor
5. Click once in the top cell in column C where you want the data
6. Command + v to paste
Here are the results:

There is no verification error here. You must select and copy to the Clipboard before the race.

How to compare two different interfaces without creating different versions?

I know that if we create two different versions of the same interface, so we can compare the two versions. But is it possible to compare two similar interfaces to each other, created in different folders?

Hi 2782749,

Not sure if it works with 11g, but possible in 12 c. In the main menu, click on ODI-> browser Version.

Click on both interfaces, and then click Compare in the upper right corner of the browser Version.

You can also export and a tool of comparison on the xml files to highlight the differences. The result will be about the same.

Comparison tools:

Windows: Compare plugin for Notepad ++

UNIX: diff

It will be useful.

Kind regards

How to compare two dates and times in BPEL?
Hi all
I need to compare two dates and times in a switch activity, but could not find any function for her.

My switch like this activity:

case Date1 > date2:
do something;
otherwise:
do something;

He is not such a function in 'The functions of Date' and can not find this function to xpath.

IBE, there is no function for a period of time to make (less one date of another?...) If this return to the data compare question).

Thank you.
Hello

Logic function as more/less function can be used to compare two dates so that same comapring two numbers.

Ex: If your variable reception contains two pieces of data such as date1 and date2, then you can use format in condition switch below.

XpathXpression (date1) > XpathXpression (date2)

hope this will help you.

How to compare the source of PL/SQL in two databases using a clever trick
Hello
Here is my scenario:

We have a very large (> 50) team of developers who work on PL/SQL.
As and as new improvements/fixes are tested successfully, DBA migrates the new source code for DEV to QA, then the PROD instance.

Very often, the developers are invited to check if the source code migrated to the instance target is the right. This Yes, because we use an automated migration tools... .and sometimes DBA can make mistake in migrating the wrong version (say a beta code).

So that developers are left with comparing the source manually or by using the file compare tools... a very tedious job.
(I know not a strict discipline to keep a barrette and version will help you; but we have a lot of existing code that does not adhere to this rule)

So, is it possible to do ' intelligently '... I thought of a way to get the code of HASH/HASHKEY of all lines of source code of a procedure or a pkg and then again to get the HASHCODE/HASHKEY of all codes/HASHKEYs of lines of source for a particular package. to get a unique HASHKEY for a pkg... .and then I can compare this HASHKEY of 2 bodies... and they are same, means the code is the same... Otherwise, the code is different

for example
Select custom_hashkey_prc (text) from dba_source, whose name = "MY_PKG.

Thank you.

Published by: DT1977 on January 19, 2009 15:31
Using a HASH to check if the two sources are the same would be a valid way to do a quick check, although it will obviously not be to tell you where the differences are.

In Oracle 10 g, you can use the DBMS_CRYPTO package to generate HASH values...

http://www.psoug.org/reference/dbms_crypto.html

We use this method to detect changes in the data where exist CLOB columns (because we cannot use set operators of SQL on CLOB).
