• Select statement with single quotes in the insert statement

  Dear Sir
  
  What's the trick to cover this issue:
  
  Insert into TEST_TABLE (SQL_SCRIPT_ID, SQL_SCRIPT)
  values ("1", "select count (*) from the SOURCE where SOURCE.") VALID = 'Y')
  
  because of the single quotes, I get an error and can not insert, the script works, is there a workaround somehow?
  
  Thank you 1 million,

• Insert into DB using SQLservice: can't take the text with single quotes:

  I use Execute sql JDBC service statement.

  I'll explain with simple code:

  insert into mytable (id, desc) values (1, 'this is the document of the customer');

  This works perfectly.

  But if I have apostrophes in the desc-

  insert into mytable (id, desc) values (1, 'this is the document the customer' );

  It is throwing error at a standstill operation errors.

  I know that in Oracle, to escape the single quotes that write us

  insert into mytable (id, desc) values (1, "it is of customer" s document ");

  But, we can not control here in Adobe as the desc is from field on a form when the user enters it.

  I'm guessing that it might be a known issue & can someone tell me the solution.

  Thank you

  Use a parameter query to avoid this problem.

  insert into mytable (id, desc) values (?,?);

  The two parameters (? brands) can be replaced by actual values using XPATH Expression.

  If you do this, you query runs without raising any errors.

• Insertion of single quotes

  With the help of FM8 on Windows XP.

  When you type in FM quotes, they are automatically converted into 'typographic', uh, ' quotes '.

  The replacement depends on settings in maker.ini.

  It's good, but for some descriptions of code I need single quotes. Y at - it a keyboard shortcut that I could use?

  [Alt] + 34 does not differ from the the wrench of the exact quote.

  I want to avoid my solution, which is to type a quote in Notepad and copy in FM.

  Thank you

  Johannes,

  Press the ESC key before you hit the quote button and you're done.

  It is indeed mentioned in the help topic entering special characters.

• How to use special characters (single quote) in input values?

  I have a query that contains a clause: field: tags_set

  (the field contains string values)

  I would like to test in sqlplus.

  I found this article https://asktom.oracle.com/pls/apex/f?p=100:11:0:P11_QUESTION_ID:113012348062 explaining how to define variables in sqlplus.

  However, my variable should contain something like ("xyz", "abc")

  I tried

  SQL > tags_set varchar2 variable

  "SQL > exec: tags_set: = '(' musique');

  "START: tags_set: = '(' musique'); END;

  *

  ERROR on line 1:

  ORA-06550: line 1, column 23:

  PLS-00103: encountered the symbol "MUSIC" when expected in the following way:

  * & = - + ; <>/ is mod remains not rem

  < an exponent (*) > <>or! = or ~ = > = < = <>and like2 or

  like4 likec between | submultiset of type multiset Member

  The symbol ' * was inserted before 'MUSIC' to continue. '

  ;

  Then I did some research and found: characters in queries

  Therefore, I changed the previous for:

  SQL > exec: tags_set: = '(\'Music\')';

  START: tags_set: = '(\'Music\')'; END;

  *

  ERROR on line 1:

  and finally

  SQL > exec: tags_set: = "{('a ')}";

  START: tags_set: = "{('a ')}"; END;

  *

  ERROR on line 1:

  The symbol ' * was inserted before 'A' to continue. '

  What is the way to make it work? (I know that I can move to something like "xyz ~ abc' and treat inside the query")

  Thanks in advance.

  A number of things.  When you define a string variable, you must give him a length or default is 1.  You can escape a quote character by doubling it (i.e. two single quotes) or you can use the q rating:

  SQL > tags_set variable varchar2 (100);

  "SQL > exec: tags_set: = '('' musique '');

  PL/SQL procedure successfully completed.

  SQL > print tags_set

  TAGS_SET

  --------------------

  ("Music")

  SQL > exec: tags_set: = q '{("music", "Drama")}';

  PL/SQL procedure successfully completed.

  SQL > print tags_set

  TAGS_SET

• Dynamic processing of single quotes in SQL

  Version: 11.2.0.4

  I'm kinda a beginner when it comes to dynamic SQL.

  I had a condition in which I had to run the following command on all the data files in the DB.

  -Expected results

  change datafile resizing '< Filename >' database 10g;

  The name of file, which is generated dynamically must be in single quotes.

  -Sample data

  create table x (file_name varchar2 (90));

  Insert into x values ('/ u04/oradata/ORCL/system.dbf');

  Insert into x values ('/ u04/oradata/ORCL/sysaux.dbf');

  Insert into x values ('/ u04/oradata/ORCL/users01.dbf');

  I managed to do it using a similair below code. But I had to do several things of trial and error to get this working in reason to get the correct number of single quotes for the string generated for v_sql below. So, I want to rethink the basics.

  declare

  v_sql varchar2 (350);

  Start

  for rec in (select x file_name)

  loop

  v_sql: = "alter database datafile"'| " Rec.file_name | " 'resize 10g;

  -RUN IMMEDIATELY v_sql;

  dbms_output.put_line (v_sql);

  end loop;

  end;

  /

  ALTER database datafile ' / u04/oradata/ORCL/system.dbf' size 10g

  ALTER database datafile ' / u04/oradata/ORCL/sysaux.dbf' size 10g

  ALTER database datafile ' / u04/oradata/ORCL/users01.dbf' size 10g

  PL/SQL procedure successfully completed.

  I would like to know the role played by each single quote. I used 8 apostrophes in the V_SQL variable above, and I numbered each single quotation mark as shown below.

  1                        234                 567           8

  |                        |||                 |||           |

  v_sql: = "alter database datafile"'| " Rec.file_name | " 'resize 10g;

  Example of output from the generation of dynamic channels:

  alter database datafile '/u04/oradata/ORCL/users01.dbf' 10g resizing

  1 and 4-> start and end of the string alter database datafile '

  3 > literal single quote of string in red in the example output

  2 > escape 3 (single literal quote of string)

  5 and 8-> start and end of the string ' resize 10 g

  6-> escape 7 (single literal quote of string)

  7 > literal single quote of string in green in the example output

  My asssumptions are correct?

  I would like to write like this.

  declare
     v_sql    varchar2(350);
  begin
    for rec in (select file_name from x)
        loop
          v_sql := q'[alter database datafile '#FILENAME#' resize 10g]';
          v_sql := replace(v_sql, '#FILENAME#', rec.file_name);
          --- EXECUTE IMMEDIATE v_sql;
          dbms_output.put_line ( v_sql);
      end loop;
  end;

  Good point!

  So it could take into account

  select * from emails
  where
  REGEXP_LIKE ( email_address, '^[a-z0-9._%-]+['']?[a-z0-9._%-]+@[a-z0-9._%-]+\.mil$','c')
  

  That exceeded that, if there is a single quotation mark, should not be the first character, and must not enter immediately before the "@".
  It also requires that it is at least 2 characters before the "@" when there is no single quote. To allow only 1 before the "@":

  SELECT     *
  FROM     emails
  WHERE     REGEXP_LIKE ( email_address
                , '^([a-z0-9._%-]+''?)?[a-z0-9._%-]+@[a-z0-9._%-]+\.mil$'
                , 'c'
                )
  ;
  

  The single quotation mark didn't need to be in square brackets.

• magic_quotes_off, now this with the single quote in the variables?

  Okay, so I turned off magic_quotes because they go far anyway. Broke one of my pages and the list of items in the table of database that is supposed to appear was not there. So, I opened the recordset on the page and deleted the apostrophes in the recordset object variables and all reappeared. That tells me I should open EVERY single game records on this site and remove the single quotes? Does that include digital as well as text?

  Thank you for your help.

  Magic quotes were originally intended to help beginners (and we are all beginners at some point), but found to be murkier than they are worth. I have to admit that the whole quote, addslashes() and stripslashes() functions had confused me for a while, and I found myself with the backslashes in all directions. It's the partition:

  When you create a query SQL in PHP, it must be a string, it must be enclosed in quotes (single or double - is not serious). However, SQL queries must be enclosed in quotes in the text, and the text you type may also contain a mixture of single and double quotes. The idea of magic quotes is that it automatically inserts a backslash before each quotation mark in a string, which makes the single quotes or double in safe to put in a SQL query text. When you pull the text from the database, you use stripslashes() to get rid of the back-slash.

  The problem is that magic quotes can be disabled, so many books and tutorials tell you move your text to function addslashes() before putting the text in a database. If magic quotes are still on, you end up with two backslashes instead of one. Nightmare. That's why magic quotes are underway.

  Rather than use the addslashes() and stripslashes() functions, it is now recommended to use mysql_real_escape_string() or prepared statements. Given that Dreamweaver does not support prepared commands, I'll leave them out of this. Whenever you pass a variable to a SQL query in Dreamweaver, it passes through the GetSQLValueString() variable, which can detect if magic quotes are enabled. If they are, it will use stripslashes() to get rid of the back-slash; and then it passes variables to mysql_real_escape_string() prepare for insertion in the database. All your single and double quotes in the text are preserved and not a backslash in sight.

  The problem is that if you have a text that has been inserted by using magic quotes and/or functions addslashes(). The simple solution is to use stripslashes() to remove the backslashes in the text stored before you post or use it somehow.

  echo stripslashes($row_recordsetName['fieldName']);
  

  I hope that clarifies the situation and provides a solution. If this isn't the case, it may be necessary to purge your database of backslashes.

  The problem with magic quotes affects only text. Numeric fields are not affected.

• Any way to generate a single quote (') with XSLT?

  Hello:
  
  I guess that's really a question of XSLT. I use the XMLType variable Transform() method to apply a style sheet. The XML code in the variable is just something simple like
  
  < TBL >
  < name > AS | JONES < / LAST_NAME >
  < name > = | MARIE < / name >
  < AGE > = | 50 < / AGE >
  < / TBL >
  
  I'm trying to get a style sheet to transform something like the above SQL such as
  

  Select * from foo where LAST_NAME like 'JONES' 
  and FIRST_NAME ='MARY'
  and AGE = 50

  But to do this, I need to generate single quotes around search terms and I can't get anything else that

  LAST_NAME LIKE 'JONES'

  . Is there a way to do this? Because now I'm generating a ~ and replacement ~ for ' all the SQL generated text throughout, but is a pretty sorry solution.
  
  I thought that something like

  <xsl:text disable-output-escaping="yes">&amp;</xsl:text>

  go to work but then is found out that he has been deprecated. I thought about character-card would work, but it's one thing to XSLT 2.0 and apparently 10g is on XSLT 1.0? In all cases, he didn't know what I was trying to do with a character map.
  
  So, I forget one obvious way to get my style sheet to insert apostrophes?
  
  Thank you.

  For example, 3-2 * i'. "

• I often struggle to create single quotes in Indesign :-(

  I often struggle to create single quotes in Indesign, I think that it is something simple that a pressing need to set, see attached, someone can advise?

  It is not a police problem.

  

  Form of apostrophe in InDesign is related to the language applied to your text - and quite rightly, because each language has its own preferences for quotation mark and apostrophe characters.

  It really seems that you type English, and yet you said InDesign that this text is in French.

  In short... you can't.  The channels are channels, and SQL and PL languages dictate that the string literals are provided within single quotes.

  I don't see how trying to retrieve more than 200 records of employees in the select statement means that you must get rid of the quotes.

  It generated when I placed between her with just two single quotes like that "BASIC");'

  There are a few basic rules I should keep in mind when you try to generate strings with single quotes?

  Hello

  In a string literal, single quotes normally indicate the beginning or the end of the literal.

  If you want to specify a single quote, is to use 2 consecutive single quotes in the literal.  For example, the name of 9 characters O'Higgins could be written in a literal string like this

  'O' Higgins

  ICT that there are 4 single quotes above: 1 to indicate the beginning of the literal string, 2 to represent a single quotation mark in the literal and 1 at the end of the literal.

  If you want a string of characters-1 that contains only a single quote, and then, as you noticed, it was released as 4 of them in a row

  ''''

  If you want to represent the 12 string

  ","BASIC");"

  in a string literal, then you have to put everything in a pair of simple and douuble quotes all quotes that occur in the sting, like this:

  (', "BASIC"); "

  When you asked if there was a rule of THUMB , you were doing a play on words?

  There is a rule of practice. When you use this type of string literal, single quotes always occur in pairs.  You always need a pair to mark the beginning and the end of the literal.  For each single quote representation, you need a pair.  If the string that represents the 12 above string literal contains 4 pairs of single quotes.  I'll write this liteal once again, with the numbers in pairs:

  (', "BASIC"); "

  122 33 44 1

  1 pair surrounds the literal; pairs of 2, 3 and 4 represent single quotes in the literal.

  If ever you have an odd number of single quotes using this notation, then you know that something is wrong.

  It is the older way of the use of single quotes in the string literal.  From Oracle 10, you have the possibility to use Q-notaation as well:

  Q'<', 'basic');="">'

  When you use Q-rating, you can have literals well trained with an odd number of single quotes.  The literal above happens to have 5, 2 that surround the literal.

  See the manual of the SQL language for more info on Q-rating:

  Can anyone tell me what role has first, second, third, fourth, fifth and sixth apostrophes play in this query (attempt 2)?

  Hello

  I numbered each Attemp2 apostrophes (successfully)

  Reading from left to right:
  (1) an encounterred of single quote when you are not already in the string literal means the beginning of a string literal
  (2) a single quote once you've started a string literal could mean the end of the literal string, or (b) a single quote, depending on which is the next character. In this case, the next character is
  (3) if (2) and (3) together are considered a single quotation mark in the string.
  (4) is the same situation as (2), and
  (5) does exactly the same thing (3), so it's another example of option (b).
  (6) is not followed by an another single quote, so it's an example of option (a), end-of-literal.

  Forget not that (lack of Q-rating) single quotes must be in pairs. Quotation marks simple all odd will be the beginning of a literal (as in your example 1) or the second pair that indicates a single quotation mark in the literal (as 3 and 5). What pairs single quotes? Just a reflection of those odd. Each single quote pairs is to be will indicate the end of the literal (as in your example 6), or the beiginning of a pair that represents a single quote in the literal (as 2 and 4).

  It can help to address the problem in this way.
  If you want that the word 'Hello' surrounded by tildes, what would you do? No problem:

  SELECT  '~hello~'
  FROM    dual;
  

  Now how can you change the tilde first a single quotation mark? The tilde is inside a string literal, so you know that you must use single quotes in a row 2. Then remove the first tilde and, instead, put 2 single quotes:

  SELECT  '''hello~'
  FROM    dual;
  

  Now how can you change the tilde to a single quote? The same way, and what you get is

  SELECT  '''hello'''
  FROM    dual;
