TRIGGER ERROR: bad bind variable

Hello

I just start with oracle and I try to do the same thing as auto_increment in mysql by creating this sequence and the trigger but the trigger, I get the following error:

error:
-----

PLS-00049: bad bind variable 'TAKEOVER_USERS.TAKEOVER_UID'

This is the code for the relaxation, table and sequence:

triggering factor:
---------

CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1" 
BEFORE
insert on "TAKEOVER_USERS"
for each row
begin
select TAKEOVER_UID.nextval into :takeover_users.TAKEOVER_UID from dual;
end;

Table:
------

CREATE TABLE  "TAKEOVER_USERS" 
   ( "TAKEOVER_UID" NUMBER NOT NULL ENABLE, 
 "TAKEOVER_FBID" VARCHAR2(20) NOT NULL ENABLE, 
 "takeover_accepted_terms" NUMBER(1,1) NOT NULL ENABLE, 
 "takeover_lastName" VARCHAR2(30), 
 "takeover_firstName" VARCHAR2(30), 
 "takeover_country" VARCHAR2(40), 
 "takeover_session" VARCHAR2(50) NOT NULL ENABLE, 
 "takeover_created" TIMESTAMP (6) NOT NULL ENABLE, 
  CONSTRAINT "takeover_users_PK" PRIMARY KEY ("TAKEOVER_UID") ENABLE
   )

sequence:
-----------

CREATE SEQUENCE   "TAKEOVER_UID"  MINVALUE 1 MAXVALUE 99999999999999 INCREMENT BY 1 START WITH 1 NOCACHE  NOORDER  NOCYCLE

Any idea what I need to change to make it work?
Thank you!

If your DB is 11g, you can try this

CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
BEFORE
insert on "TAKEOVER_USERS"
for each row
begin
:NEW.TAKEOVER_UID:=TAKEOVER_UID.nextval;
end;

If 10g or more...

CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
BEFORE
insert on "TAKEOVER_USERS"
for each ROW
BEGIN
SELECT TAKEOVER_UID.NEXTVAL INTO :NEW.TAKEOVER_UID FROM dual;
end;

Thanks for help.

Based on the declaration of the customer table you posted columns are created in lowercase. Therefore, you must use the names of column between quotation marks:

create or replace

check_tax_number relaxation

INSERT BEFORE THE "C ##MYUSER". "customer" FOR EACH ROW

BEGIN

IF : new. " taxpayer""" <> '0' THEN

: new. " " "taxnumber""": = "123456789"; -error here...

You wrote trigger on the table of the student. So in the trigger, only the columns of this table must be offered for example: NEW.zip.

Since zip_id is not part of this table, the: NEW.zip_id must always generate the error.

insert into student_v (zip) values('111');

In the above statement, you can only provide the value for the column zip but not zip_id. Therefore, the: NEW.zip_id is not available in the trigger. Must extract this value in the sequence after it is created.

for example

create the test of the order;

INSERT INTO postal code

(zip,

zip_ID,

created_by,

CREATED_DATE,

Modified_By,

MODIFIED_DATE)

VALUES (: NEW.zip,)

test.nextval,

NULL,

USER,

SYSDATE,

USER,

SYSDATE);

Hello world

Making my first attempt to bind variables. What I've read it really improves performance.

The code below works fine until I try to do TEST1_PROC. P_WHERE a bind variable with the ':' prefixed, such as: P_WHERE.

You do not specify bind variables by a colon ': ' prefix in PL/SQL.

The stored procedure generates a query using the string concatenation. If you remove your name from the variable of the colon you still don't use bind variables.

If you want to use bind variables you should consider the following:

1. use the DBMS_SQL package.
2. use EXECUTE IMMEDIATE with the USING clause.
3. use OPEN TO with the USING clause.

Each has different advantages/disadvantages.

If looks as if you want to pass in a dynamic list. If you are using bind variables, it will effectively address the entire list as a value surrounded by single quotes. If you really want a dynamic IN the list, you need to investigate another method.

Tom Kyte contains information about the lists into dynamic here: [how to make a variable in the list? | http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:210612357425]

Bad connection variable? I'm doing a host variable.
Okay, so I said a global variable:

VARIABLE g_total NUMBER

and I want to use this variable to store the results of a stored procedure (I reduced my code to focus on the problem area):

CREATE OR REPLACE PROCEDURE my_procedure
(p_price IN m_movies.price%TYPE
p_quantity IN m_cart.quantity%TYPE)
IS
BEGIN
: g_total: = p_price * p_quantity;
DBMS_OUTPUT. Put_line ("the order total is: ' |: g_total");
END;
/

After all this, I get an error "bad bind variable g_total ' for the two lines I use it inside the procedure. What the heck is a variable binding? I use a host variable. (I think). If this has nothing to do with the fact that I can only give a very generic NUMBER data type to the host variable? Help, please!
It's not the way it will work. You cannot create choice with lie (as you saw).
You had rather code like this:
```
SQL> VARIABLE g_total NUMBER

SQL> create or replace procedure my_procedure (p_price      in     number,
                                          p_quantity   in     integer,
                                          g_total         out number)
is
begin
   g_total := p_price * p_quantity;
end my_procedure;
/
Procedure created.

SQL> exec my_procedure(50,3, :g_total)

Oracle.ManagedDataAccess gives ORA-01006 if there is bind variables in the comments, but only on the lines.

When I go from ODP.NET to the ODP.NET managed some of my questions begins to throw errors missing bind variable.
I reproduced with a simple example that uses a variable called liaison: unitName
It's the example SQL:
SELECT
: unitName
Of
DOUBLE
Now, if I add a comment at the beginning of the SQL like this:
-Text with: unitName
SELECT
: unitName
Of
DOUBLE
It works, but if I have a variable binding in a comment that is located on a number of the 'same' line, I get ORA-01006:
This causes the error:
-First line comment
-Text with: unitName
SELECT
: unitName
Of
DOUBLE
Kind regards
-Tommy

I was able to reproduce this problem. I filed Bug 19433348 on your behalf.

The circumstances in which the bug occurs are fairly easy to get around.

(1) remove the colon in the second commented line.

(2) add a space between the '\n' and ' - '.

If you are one of those things, you won't encounter the bug behavior.

The view was created with quotes around column names, so that they are case-sensitive. You need to either modify your trigger double quote column names, or rebuild the view without the quotes. Personally, I'd go with changing the display.

Variable with a value. «PURGE error: bad Argument Type.»
Hi, my 50G calculator accuses a value for the variable 'X' but I can't find it in any directory, and when I try to delete I get the message "' PURGE error: bad Argument Type." " I also have the theta variable with the same problem. How can I remove the value of these variables? TKS

In addition to Make suggestions, two other possibilities come to mind: 'X' can be a directory object (which would cause the error to the wrong Type of Argument because non-empty directory objects cannot be purged by PURGE, but must be purged by PGDIR), or it could be a local variable (which can only be served by putting an end to the environment that created which is usually a program). So if Make suggestions don't work, try foster 'X' PGDIR and if that does not work, try KILL (which ends all the current environments).

If those WHO do not work, please do 'X' TYPE HOME and tell us what object type 'X'.

Trace files showing the bind variable value =""
10g on solaris

Hi all

We have a problem with an informatica workflow brings an update statement in Oracle in trems of performace.

I started using DBMS_SUPPORT tracing with lie the TRUE value. He captured the trace files accordingly against a controlled set of data. Trace TWOT files were produced.

Trace files first shows the SELECT statement are questions that identifies the records that will be updated.

The 2nd trace file shows the actual UPDATE statement published as a PL/SQL loop to do the update.

There are 20 records that users have rigged last updated and the update statement lists 20 cases where updates taking place. All updates occurred successfully after reviewing the results of the post. However my question is why the trace files are showing the values of bind as the value ""?... any ideas appreciated!

'dty = 1' indicates that the data type is VARCHAR or NVARCHAR. As the timestamp data types data types BLOB, and various other, bind variables defined as NVARCHAR will not have their values dumped in a 10046 trace file. I suspect that the: 1 binding variable is passed as an a NVARCHAR2.

Estimate of poor cardinality using Bind Variables

Hi I'm using the 11.2.0.4.0 Oracle version. I have a query that is underway for the plan of the poor execution by the estimate of poor cardinality for two tables (I've extracted and published this part only) as I mentioned below, the individual conditions for which the estimate goes bad and moving entire query execution path.

These are for two tables and currently we use BIND variable for them in our code, and I notice, its best estimate gives with literals. I need to know how to handle this scenario that I need this query to execute for all types of volumes. Is there something I can do without changing the code, as it works well for most of the execution? In the current scenario of the main query that uses those below tables providing a plan (index + nested loop) that works very well for small volume, but running for 10 hr + for large volume as ideally its going to the same regime.
And Yes, most time that this request will be hit for small volume, but killing some appearance of large volume presents the performance of the queries.

Here are the values of the variable binding.

In fact for literals, I did not find any section of the predicate after running the sql code with activation "set autotrace traceonly explain."

The main problem is with another large query whose cardinality is underestimated due to the presence of these table (table1, table2) with the above mentioned clause, and the query is for the analysis of index + nested with values of Bind loops and take 10 hr +, whereas with literals, its completion in ~ 8minutes with FTS + Hash Join.

Your real problem is that you try to have just a single SQL query handle all POSSIBLE thanks to the use of embedded FILTERS ' either / or ' filters in the WHERE clause. You want only a select this OPTION to run whatever filters have been selected at run time by the user or the application using it. And it would never work. You really need to SELECT different queries for different combinations of filter conditions.

Why? Think for a minute. How Oracle works internally? A SQL SELECT query gets analyzed and an execution plan is produced which is stored in the library cache and gets REUSED on all subsequent executions of this query - except in certain cases where there may exist several plans run through several cursors of the child. So with only SELECT a query you only AN execution plan in the library cache, to be used by all THE executions of this query, regardless of the value of your run-time binding variables.

Lets put another way - each library cache execution plan is associated with a SQL statement. If you want a DIFFERENT execution plan then you need run a DIFFERENT SQL statement. That's how you get a different execution plan - by running a different SQL statement. Running the SAME SQL query generally you will get the SAME execution plan every time.

In addition, because of the "either / or" filters that you use you will end up generally with a full Table Scan on each of the referenced tables. Why? Given that the optimizer must produce an implementation plan that manages all possible contingencies for all values of possible bind variables in the SELECT. If the optimizer should choose to use any index based on one of these "either / or" filters then it would only help performance when real value was provided, but it would be really bad if a NULL value was supplied. If the optimizer ends up ignoring the index because they are not always optimal for all possible input values and instead chose a plan that is "good enough" for all input values possible. That means that it will use a scanning Table full.

I hope you can see that it is precisely what is happening for you with your query. You select this OPTION to manage the different combinations of filter, which leads to the execution plan only one, which leads to scans full Table on the referenced tables in these ' either / or ' filters.

The solution? Build queries SELECT DIFFERENT when input values are NULL. How you do that? Read this article to ask Tom that tells you:

http://www.Oracle.com/technetwork/issue-archive/2009/09-Jul/o49asktom-090487.html

To sum up - when you have real value for a bind variable 'bind_var1' add the following filter to your CHOICE:

AND column_name1 =: bind_var1

When the binding variable is NULL, add the filter according to your CHOICE:

AND (1 = 1 OR: bind_var1 IS NULL)

Now, you'll have 2 queries SELECT must be performed, which have exactly the same number of variables in the same order bind, which is important. When you then run one of these variations, Oracle can analyze and optimize each one SEPARATELY, with a single execution by the SELECT query plan.

When you provide a real value, the filter is a normal 'column = value' that the optimizer can use all indexes on this column, because NULL values are not referenced.

When there is no real value, the optimizer will analyze the '1 = 1 GOLD' and realize that "1 = 1" is set to TRUE and GOLD, it is quite TRUE regardless because the binding variable is null or not. This means that the optimizer will actually REMOVE this filter, because it filters nothing because it is always TRUE. You will end up with an operating plan based on the other filters in the query, which is what you want because you have no filter on this column.

What is it - producing distinct SELECT queries to determine if you have a real value to filter or not you end up with DIFFERENT execution plans for each of them, and each of them is OPTIMAL for this particular set of filters. Now you get good performance for each variation of the performance of the SELECTION, rather than sometimes good and sometimes very bad when using SELECT only one. It is impossible to try to get multiple shots of execution 'optimal' out of a SELECT query. That's why you get mediocre performance under different bound the values of the variables.

SQL * more substitution vs bind variable question

Hi all, I am trying to automate some SQL within SQL codes * more script that is triggered by a script .bat, the only parts that change are Dates...
example:
create table blah as
Select * from table
WHERE DATE between start_date and END_DAY;
the DATE is a numeric field, YYYYMMDD
The script runs always at the beginning of a new week, so a Monday, unless a public holiday, then a Tuesday.
The END_DAY is * always * last Friday and I realized that:
variable L_FRIDAY char (15);
Start
Select to_char (next_day(sysdate-7,'FRIDAY'), 'YYYYMMDD') as Last_Friday in: double L_FRIDAY;
end;
/
The thing is that I get an error when I try to use the binding variable?
create table blah as
Select * from table
WHERE DATE between start_date and: L_FRIDAY;
Then once I found the end date, I was going to use add_months(L_FRIDAY,-12) for previous 12 months for the start_date...
When I tried to use a variable Substitution I could just hard code the date, but I can not or do not know how to set the value of this exec to the variable?
Help!
:-)
Basically my research reveals that - Bind variables are not allowed for operations of data definition, use substutions instead of bind variables
I need an automated way to find the END_DAY which is last Friday and START_DATE that is 12 months before Friday and refer to those in the SQL without errors.

Or SQL * more bind variable or variable substitution can be DATEs. The best you can do is set a different type, as a string, representing a date. A string as June 19, 2015"represents a date, but so strings like 'SYSDATE' and ' SYSDATE - 7', so you can do something like this:

SET l_friday = ' NEXT_DAY ((SYSDATE-7), 'FRIDAY').

DEFINE start_date = "ADD_MONTHS (& l_friday, - 12)"

SELECT & start_date AS t_n

, & l_friday AS l_f

OF the double

;

Output (when executed on 25 June 2015):

L_F T_N

Passing literal as a bind variable in Jena

Hi all
We are able to use bind variable with the id RDFVID. However, if we want to check for a literal using the jena/joseki adapter we are not able to perform the same operation. In our case the literal is of type string.
We use:
* WLS 12.1.0.3.
* Adapter Jena 2.11.1.
* Joseki 3.4.4.
* ARQ 2.9.2.
We try to run the following query on the stop of joseki.
PREFIX foaf: http://xmlns.com/FOAF/0.1/ >
PREFIX vcard: http://www.w3.org/2001/vCard-RDF/3.0# >
PREFIX xsd: http://www.w3.org/2001/XMLSchema# >
PREFIX oext: < http://Oracle.com/Semtech/Jena-adaptor/ext/function# >
PREFIX ORACLE_SEM_FS_NS: http://Oracle.com/Semtech#no_fall_back, ALLOW_DUP = T, s2s >
PREFIX ORACLE_SEM_HT_NS: http://Oracle.com/Semtech#monitor >
PREFIX ORACLE_SEM_UEAP_NS: http://oracle.com/semtech#f$ RDFVID % 20 (ORACLE_ORARDF_RES2VID(?)) >
PREFIX ORACLE_SEM_UEPJ_NS: http://Oracle.com/Semtech#f $RDFVID >
PREFIX ORACLE_SEM_UEBV_NS: http://Oracle.com/Semtech# 'Lee' >
SELECT? f
WHERE
{graph? g {? vcard:N p? vn.}}
? VN vcard:Family? f.
? FOAF:title p 'Sen'.}
}
The result set is empty. Replace the line 'ORACLE_SEM_UEBV_NS PREFIX: <http://oracle.com/semtech# "Lee"> "by any Variant is to be given an error or the empty set. (Some variants (& quot;)) Lee & quot; Lee, "Lee" & #39; Lee & #39; )
When we use the generated SQL code of jena/joseki, we are able to get the right result if we execute the query even in SQLDeveloper. To use the variable binding is "Lee" (the binding variable is the price included). This will give you a correct result in withdrawal.
Kind regards
Max

Hi Max,.

In the area of the UEBV, you must put "Lee" encoded in URL string

Please, try the following and see if it helps.

% 22Lee % 22

Thank you
