mysql update (i want to change the string last two character) - mysql

i have a string
www.baabrada.aapnipanchayat.org
i want to change the string
www.baabrada.aapnipanchayat.in
and i have use this update query
UPDATE `gram_panchayat` SET web=in WHERE web=org;

Ensures what .org be replaced with .in only at the end of string:
UPDATE gram_panchayat
SET web = CONCAT(LEFT(web, CHAR_LENGTH(web)-CHAR_LENGTH('org')), 'in')
WHERE web LIKE '%.org'
Test it: http://sqlfiddle.com/#!2/e78a26/1
More info: String Functions

Another way to do this would be to use the INSERT() function:
UPDATE gram_panchayat
SET web = INSERT(web,
CHAR_LENGTH(web) - CHAR_LENGTH('org') + 1,
CHAR_LENGTH('org'),
'in'
)
WHERE web LIKE '%.org';
Here's a SQL Fiddle demo to play with: http://sqlfiddle.com/#!2/524905/1

ssrs ORA_01008:NOT ALL VALIABLE BOUNDED [duplicate]

I have come across an Oracle problem for which I have so far been unable to find the cause.
The query below works in Oracle SQL developer, but when running in .NET it throws:
ORA-01008: not all variables bound
I've tried:
Changing the Oracle data type for lot_priority (Varchar2 or int32).
Changing the .NET data type for lot_priority (string or int).
One bind variable name is used twice in the query. This is not a problem in my
other queries that use the same bound variable in more than one
location, but just to be sure I tried making the second instance its
own variable with a different :name and binding it separately.
Several different ways of binding the variables (see commented code;
also others).
Moving the bindByName() call around.
Replacing each bound variable with a literal. I've had two separate variables cause the problem (:lot_pri and :lot_priprc). There were some minor changes I can't remember between the two. Changing to literals made the query work, but they do need to work with binding.
Query and code follow. Variable names have been changed to protect the innocent:

Why is Oracle claiming that not all variables are bound?
I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.
By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.
Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.
The correct way is to set the BindByName property of OracleCommand to true as below:
var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;
You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post
I found how to run the query without error, but I hesitate to call it a "solution" without really understanding the underlying cause.
This more closely resembles the beginning of my actual query:
-- Comment
-- More comment
SELECT rf.flowrow, rf.stage, rf.process,
rf.instr instnum, rf.procedure_id, rtd_history.runtime, rtd_history.waittime
FROM
(
-- Comment at beginning of subquery
-- These two comment lines are the problem
SELECT sub2.flowrow, sub2.stage, sub2.process, sub2.instr, sub2.pid
FROM ( ...
The second set of comments above, at the beginning of the subquery, were the problem. When removed, the query executes. Other comments are fine.
This is not a matter of some rogue or missing newline causing the following line to be commented, because the following line is a SELECT. A missing select would yield a different error than "not all variables bound."
I asked around and found one co-worker who has run into this -- comments causing query failures -- several times.
Does anyone know how this can be the cause? It is my understanding that the very first thing a DBMS would do with comments is see if they contain hints, and if not, remove them during parsing. How can an ordinary comment containing no unusual characters (just letters and a period) cause an error? Bizarre.
You have two references to the :lot_priprc binding variable -- while it should require you to only set the variable's value once and bind it in both places, I've had problems where this didn't work and had to treat each copy as a different variable. A pain, but it worked.
On Charles' comment problem: to make things worse, let
:p1 = 'TRIALDEV'
via a Command Parameter, then execute
select T.table_name as NAME, COALESCE(C.comments, '===') as DESCRIPTION
from all_all_tables T
Inner Join all_tab_comments C on T.owner = C.owner and T.table_name = C.table_name
where Upper(T.owner)=:p1
order by T.table_name
558 line(s) affected. Processing time: 00:00:00.6535711
and when changing the literal string from === to ---
select T.table_name as NAME, COALESCE(C.comments, '---') as DESCRIPTION
[...from...same-as-above...]
ORA-01008: not all variables bound
Both statements execute fine in SQL Developer. The shortened code:
Using con = New OracleConnection(cs)
con.Open()
Using cmd = con.CreateCommand()
cmd.CommandText = cmdText
cmd.Parameters.Add(pn, OracleDbType.NVarchar2, 250).Value = p
Dim tbl = New DataTable
Dim da = New OracleDataAdapter(cmd)
da.Fill(tbl)
Return tbl
End Using
End Using
using Oracle.ManagedDataAccess.dll Version 4.121.2.0 with the default settings in VS2015 on the .Net 4.61 platform.
So somewhere in the call chain, there might be a parser that is a bit too aggressively looking for one-line-comments started by -- in the commandText. But even if this would be true, the error message "not all variables bound" is at least misleading.
The solution in my situation was similar answer to Charles Burns; and the problem was related to SQL code comments.
I was building (or updating, rather) an already-functioning SSRS report with Oracle datasource. I added some more parameters to the report, tested it in Visual Studio, it works great, so I deployed it to the report server, and then when the report is executed the report on the server I got the error message:
"ORA-01008: not all variables bound"
I tried quite a few different things (TNSNames.ora file installed on the server, Removed single line comments, Validate dataset query mapping). What it came down to was I had to remove a comment block directly after the WHERE keyword. The error message was resolved after moving the comment block after the WHERE CLAUSE conditions. I have other comments in the code also. It was just the one after the WHERE keyword causing the error.
SQL with error: "ORA-01008: not all variables bound"...

Here is what the dataset parameter mapping screen looks like.
It's a bug in Managed ODP.net - 'Bug 21113901 : MANAGED ODP.NET RAISE ORA-1008 USING SINGLE QUOTED CONST + BIND VAR IN SELECT' fixed in patch 23530387 superseded by patch 24591642
Came here looking for help as got same error running a statement listed below while going through a Udemy course:
INSERT INTO departments (department_id, department_name)
values( &dpet_id, '&dname');
I'd been able to run statements with substitution variables before. Comment by Charles Burns about possibility of server reaching some threshold while recreating the variables prompted me to log out and restart the SQL Developer. The statement ran fine after logging back in.
Thought I'd share for anyone else venturing here with a limited scope issue as mine.
I'd a similar problem in a legacy application, but de "--" was string parameter.
Ex.:
Dim cmd As New OracleCommand("INSERT INTO USER (name, address, photo) VALUES ('User1', '--', :photo)", oracleConnection)
Dim fs As IO.FileStream = New IO.FileStream("c:\img.jpg", IO.FileMode.Open)
Dim br As New IO.BinaryReader(fs)
cmd.Parameters.Add(New OracleParameter("photo", OracleDbType.Blob)).Value = br.ReadBytes(fs.Length)
cmd.ExecuteNonQuery() 'here throws ORA-01008
Changing address parameter value '--' to '00' or other thing, works.

remove part of string record in mysql

this is my string record on tables in mysql
"ftp://myftp.co/ftp/Media_Gallery//Cartoon/Serries/Shaun_The_Sheep/Shaun_The_Sheep_E015.mkv"
now i want remove "//" at the center of my string after "Media_Gallery"
but when i use replace queries // this query remove // at the first of URL and its wrong
my string after run query would be this scheme:
"ftp://ftp.um.ac.ir/ftp/Media_Gallery/Cartoon/Serries/Shaun_The_Sheep/Shaun_The_Sheep_E015.mkv"
UPDATE Mytable SET name = REPLACE(name, 'y//', 'y/');

REPLACE string in MySQL but only specified part

i would like to replace string in my query but only on the end of the string this is my example:
SET #exampleString = 'example_a_chapter_a';
SELECT REPLACE(#exampleString ,'_a','_b1');
Result what I get is this: example_b1_chapter_b1
But i would like this: example_a_chapter_b1
But there can be more time the '_a' in the string as this 'example_a_type_a_chapter_a', but
i would like to replace just the end '_a' of the string.
Thanks for you help
This will be tricky since MySQL can not replace by regex. One of possible ways is:
SELECT REPLACE(REPLACE(CONCAT(#exampleString, '#END'), '_a#END', '_b1'), '#END', '');
-i.e. add something that 100% is not in original string, to it's end and then replace.
Edit: second REPLACE is needed in case if original string doesn't end with _a (so you'll need to remove added #END)
You could not use replace() at all. Just reconstruct the string:
select (case when #exampleString like '%_a'
then concat(left(#exampleString, length(#exampleString) - length('_a')),
'_b1'
)
else #exampleString
end)
This has the advantage that it works even when the string doesn't end in '_a'.

Incrementing numerical value and changing string in SQL

I have a database that has stored values in a complicated, serialized array where one component is a string and another is the length of the characters of the string, in this format:
s:8:"test.com"
Where "s" holds the character length of the string in the quotations.
I would like to change the string from "test.com" to "testt.com", and I'm using the following statement in SQL:
UPDATE table SET row=(REPLACE (row, 'test.com','testt.com'))
However, this breaks the script in question, because it doesn't update the character length in the "s" preceding the string where "test.com" is stored.
I was wondering if there is a query I can use that would replace the string, and then also increment the value of this "s" preceding to where the replacement occurs, something like this:
UPDATE table SET row=(REPLACE (row, 's:' number 'test.com','s:' number+1 'testt.com'))
Does anyone know if this kind of query is even possible?
UPDATE table set row = concat('s:',length('testt.com'),':"testt.com"');
If you need to change exact string, then use exact query -
UPDATE table SET row = 's:9:"testt.com"' WHERE row = 's:8:"test.com"';
The string is a "serialized string".
If there are multiple strings to be replaced, it might be easier to create a script to handle this.
In PHP, it goes something like this:
$searchfor = serialize('test.com');
$replaceby = serialize('testt.com');
// strip last semicolon from serialized string
$searchfor = trim($searchfor,';');
$replaceby = trim($replaceby,';');
$query = "UPDATE table SET field = '$replaceby' WHERE field = '$searchfor';";
This way, you can create an exact query string with what you need.
Do fill in the proper code for db connection if necessary.

Change image name and update into same table using mysql query

I want to change image name in table like below.
image name : test.png
replace with : test_E.png
I want _E at end of all image name in table using mysql query.
Use replace function
update <table>
set image=replace(image,'.png','_E.png')
you could use this, if the image extension is not same in the table
update <table>
set image=concat(substring(image,1,locate('.',image)-1),'_E',
substring(image,locate('.',image),lenght(image)))
You can use string functions of MySQL query:
UPDATE TABLE SET IMAGE_NAME = CONCAT(SUBSTR(IMAGE_NAME,(CHAR_LENGTH(IMAGE_NAME) - 4)),
'_E' , SUBSTR(IMAGE_NAME, -4)) WHERE ID = <put record id>;
SUBSTR(IMAGE_NAME,(CHAR_LENGTH(IMAGE_NAME)-4)) would return name of file - assuming extension is of 3 chars. For 'test.png' above function would remove '.png' and function would return 'test'
SUBSTR(IMAGE_NAME, -4) would return last four chars of string - so 'test.png' would return '.png'
using concat you can concat 'test', '_E' and '.png' - returning 'test_E.png'
