dbms_xmlgen. GetXml with single quotes

Can you get it someone please let me know what is wrong with this query. I try to convert the long and CLOB type. I wanted to convert long to varchar2 and to do this, I am to convert the long to clob or varchar2 clob.

The query works fine when doing a rownum = 1 in the dynamic query but I would like to read carefully all the constraints so tried the underside and its failure with an error message for an unexpected end of SQL command.

-with rownum

SELECT dbms_lob.substr (longtoclob, 4000, 1) text

of the double.

(select (dbms_xmlgen.getxml ("SELECT t.search_condition ALIASLONG

OF All_Constraints t WHERE rownum = 1')) longtoclob

the double) Y where DBMS_LOB. GETLENGTH (Y.longtoclob) > 0;

-generic query

Select (SELECT (dbms_xmlgen.getxml (Q'[select search_condition in all_contstaints where cosntraint_name = ']' | constraint_name |))) Q '[']')) text, constraint_name from

ALL_CONSTRAINTS

where rownum < = 3;

-generic query

Select (SELECT (dbms_xmlgen.getxml (Q'[select search_condition in all_contstaints where cosntraint_name = ']' | constraint_name |))) Q '[']')) text, constraint_name from

ALL_CONSTRAINTS

where rownum<>

'A few' bad stuff here:

-keyword SELECT extra

-typos in names of objects

-DBMS_XMLGEN.getXML will give you a CLOB that represents a dataset XML to canonical format, not the search_condition directly necessary

It is more what you are looking for, but know it's slow:

select constraint_name
     , xmlcast(
         dbms_xmlgen.getxmltype(
           'select search_condition from all_constraints where constraint_name = ' || dbms_assert.enquote_literal(constraint_name)
         )
         as varchar2(4000)
       ) as text
from all_constraints
where rownum <= 3 ;

(XMLCAST is 11g only, use the extractValue on lower versions)

    Sorry; It is unclear what you are trying to do, and what you're doing.
    I think the only single-quoptes in m_swhere are those before and after SCOTT:

    DEFINE  m_sWhere = owner='SCOTT'
    

    That's what you need to be able to use this variable in an SQL statement. SQL * more will replace & 1 with its value. If you were typing the statement directly, just type a single before and after SCOTT quote, if you want only a single quote before and after SCOTT in m_swhere. You use 2 single quotes in a row inside string literals, but the string literal only you need here is the literal 5 characters 'SCOTT', containing sound ", a 'C', 'o', two ' t and single quotes to zero."

    MyReport.sql
    OK: SELECT * FROM MyTable WHERE & 1
    ERR: dbms_output.put_line ('MyWhere: &1');)

    I am not able to print the where the clause. I already tried to set the where clause with other delimiters (e.g. #SCOTT #) and replace # by ' in the MyReport but failed as well.

    You do not want channels OK: or ERR: in the script.
    Dmbs_output.put_line, like any procedure, only works in PL/SQL.
    If you want to display text in a SQL * more script, use the SQL * FASTER command, like this:

    PROMPT  MyWhere: &1
    

    If you really must use dbms_output.put_line, then you will need to use a string literal, and single quotes can be tricky.
    In Oracle 10 (and more) use Q-rating:

    BEGIN
        dbms_output.put_line ( Q'{MyWhere: &1}' );
    END;
    /
    

    {Quotes will not be a problem unless they occur immediately after a right '}'.

  • 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

    KC

    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.

    To print a single quotation mark, use two single quotes (IE he "s to print from) and to print a string to write the string inside the single quotation mark as"Hello Word ".
    You want to print "Hello World" your sql will be

    SELECT '''Hello World'''
       FROM dual;
    

    You get the following error as search oracle of KEYWORD Analyzer after "that a chain is closed using the" quote

    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:

  • 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 &apos;JONES&apos;
    . 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.

  • Problems with DBMS_XMLGEN.getXML add features

    Hello

    I use DBMS_XMLGEN on 11 GR 2.

    The documentation Pages of PL/SQL and Types Reference 11 GR 2 (July 2013) reads as follows:

    GETXML functions

    This function returns the XML document. The function is overloaded.

    Syntax

    Gets the XML document from the maximum number of rows specified. It

    adds the XML in the CLOB passed Use this version of GETXML

    To avoid extra CLOB copies and reuse the same CLOB for subsequent functions

    calls. Due to the CLOB reuse, this GETXML Functionscall is potentially more

    effective:

    DBMS_XMLGEN. GETXML)

    CTX IN ctxHandle,

    tmpclob IN OUT NCOPY CLOB,

    dtdOrSchema in numbers: = NONE)

    RETURN A BOOLEAN VALUE;

    11 GR 2 Guide (February 2014) developer Oracle DB XML stipulates the following:
    Parameters

    getXML (ctx IN ctxHandle,

    clobval IN OUT NCOPY clob,

    dtdOrSchema in numbers: = NONE);

    CTX -The context handle from call

    newContext.

    clobval (IN/OUT) - the CLOB to which the XML document is

    being attached,

    dtdOrSchema -If you need to generate the DTD or

    Schema. This parameter is NOT supported.

    Use this version of the function getXML, in order to avoid any supplement

    CLOB copies and if you want to reuse the same CLOB for

    subsequent calls. This getXML call is more effective than the other

    flavor, even if it means that you create the LOB reference.

    When you generate the XML, the number of lines specified by the

    setSkipRows call are ignored, then the maximum number of

    ranks as specified by the setMaxRows call (or all if

    not specified) is read and converted into XML. Use of the

    getNumRowsProce

    I'm bringing 2 parts of XML document.  I use 2 hierarchical queries.  One to generate hierarchical header of a table and another information to generate information of hierarchical detail to a separate table. My code is generally as follows:

    DECLARE

    hdrctx DBMS_XMLGEN.ctxHandle;

    detailctx DBMS_XMLGEN.ctxHandle;

    hdrdoc CLOB.

    BOOLEAN success;

    hdrqry VARCHAR2 (2000): = ' SELECT LEVEL, XMLELEMENT (EVALNAME HTAGNAME, HTAGVAL) OF HDRTABLE

    CONNECT HSUBSEQ = PRIOR HGRPSEQ';

    --

    detailqry VARCHAR2 (2000): = ' SELECT LEVEL, XMLELEMENT (EVALNAME DTAGNAME, DTAGVAL) OF DETAILTABLE

    CONNECT DSUBSEQ = PRIOR DGRPSEQ';

    BEGIN

    hdrctx: = DBMS_XMLGEN.newContextFromHierarchy (hdrqry);

    detailctx: = DBMS_XMLGEN.newContextFromHierarchy (detailqry);

    DBMS_LOB.CREATETEMPORARY (hdrdoc, true);

    DBMS_XMLGEN. GetXml (hdrctx, hdrdoc);

    -dbms_output.put_line (hdrdoc);

    DBMS_XMLGEN. GetXml (detailctx, hdrdoc);

    DBMS_XMLGEN.closeContext (hdrctx);

    DBMS_XMLGEN.closeContext (detailctx);

    dbms_output.put_line (hdrdoc);

    DBMS_LOB. FREETEMPORARY (hdrdoc);

    END;

    I also tried the next iteration:

    BEGIN

    hdrctx: = DBMS_XMLGEN.newContextFromHierarchy (hdrqry);

    detailctx: = DBMS_XMLGEN.newContextFromHierarchy (detailqry);

    DBMS_LOB.CREATETEMPORARY (hdrdoc, true);

    hdrdoc: = DBMS_XMLGEN.getXML (hdrctx);

    -dbms_output.put_line (hdrdoc);

    DBMS_XMLGEN. GetXml (detailctx, hdrdoc);

    DBMS_XMLGEN.closeContext (hdrctx);

    DBMS_XMLGEN.closeContext (detailctx);

    dbms_output.put_line (hdrdoc);

    DBMS_LOB. FREETEMPORARY (hdrdoc);

    END;

    The two sources of documentation indicates that version 3 of overload of getXML parameter adds the CLOB parameter that is passed and yet I am not able to get the details to add to the header.  If I Uncomment the first put_line I get a document of xml output containing the header as expected information.  However, the second put_line outputs of an xml document that contains only the detail information and none of the header information.  It is not adding as stated in the documentation, but substitute instead.  Any ideas what is happening here and how I can get the feature of adding such as specified in the documentation?

    An additional but trivial problem is the difference in the documentation.  Documentation packages and types indicates that 3 parameter getXML overload returns a BOOLEAN value.  DB XML Dev Guide does not indicate this.  When I use this, the call works as a process and not a function, but I'm failed in the 3rd parameter, which must by default to NONE.  I want to just make sure that using the 2 explicit and implicit parameters 1 is not ending up with me call the wrong version.

    Thanks in advance for any help you can give me on this point,

    Because that the additional XML prologue is a specific, defined in section it is easy to remove.

    The best way to get something is to not generate it.

    This is the meeting of the 2 segments arbitrarily dimensions and structured it's much more embarrassing for me.

    What you mean?

    I'll look into the possibility of restructuring in those non-hierarchical hierarchical queries as a work-around.

    Don't bother it.

    Simply add two structures manually instead of using a 'function' who obviously don't get you any advantage.

    for example

    DECLARE

    hdrctx DBMS_XMLGEN.ctxHandle;

    detailctx DBMS_XMLGEN.ctxHandle;

    doc CLOB.

    hdrqry VARCHAR2 (2000): = ' SELECT LEVEL, XMLELEMENT ("emp", xmlattributes (empno as "id")) FROM scott.emp

    CONNECT BY prior empno = mgr

    Start with mgr is null';

    detailqry VARCHAR2 (2000): = ' SELECT LEVEL, XMLELEMENT ("emp2", xmlattributes (empno as "id")) FROM scott.emp

    CONNECT BY prior empno = mgr

    Start with mgr is null';

    BEGIN

    hdrctx: = dbms_xmlgen.newContextFromHierarchy (hdrqry);

    detailctx: = dbms_xmlgen.newContextFromHierarchy (detailqry);

    DBMS_LOB.CREATETEMPORARY (doc, true);

    Select xmlserialize (document

    XmlElement ("root"

    dbms_xmlgen.getxmltype (hdrctx)

    dbms_xmlgen.getxmltype (detailctx)

    )

    as clob dash

    )

    in the doc

    Double;

    dbms_xmlgen.closeContext (hdrctx);

    dbms_xmlgen.closeContext (detailctx);

    dbms_output.put_line (doc);

    DBMS_LOB.freeTemporary (doc);

    END;

    /

    output:

    
      
        
          
            
          
        
        
          
          
          
          
          
        
        
          
        
      
      
        
          
            
          
        
        
          
          
          
          
          
        
        
          
        
      
    
    
  • 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.

  • replace a single quote with the double quotes with the function replace

    I work with one apex page, which contains a text as a filter box. If I put a single quote and find then I get the error message saying that parse error.

    For this, I want to replace one single quotation mark with double quotes, so this should be perfect. and apex should show the result.

    A allow the query to the same which will replace the single quote with double quotes.

  • Using single quotes with MaxL in batch scripts

    I have the following MaxL, I need to pass to essmsh via a batch script:

    run the calculation ' FIX("Member 1") CLEARDATA "member 2"; ENDFIX' on App.Db;

    The problem is that the single quotes cause problems when it is passed as a variable in the batch script. However, if I change single quotes to double quotes the batch script is happy but the MaxL is not valid.

    Please can anyone suggest how I can get this to work?

    You also try that works

    ( @echo login %USER% identified by %PASS% on %SERVER%; & @echo execute calculation "'FIX(\"Member 1\") CLEARDATA \"Member 2\"; ENDFIX'" on App.Db; & @echo logout; & @echo exit; ) | essmsh
    

    See you soon
