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?
If you’re a developer working with Oracle databases, you may have encountered the ORA-01008 error message: «Not all variables bound.» This error occurs when a SQL query has placeholders for bind variables (parameters), but not all of them have been assigned a value. When this happens, Oracle cannot execute the query because it doesn’t know what values to substitute for the placeholders.
Fortunately, the solution is usually straightforward. In this guide, we’ll walk through the steps you can take to troubleshoot and resolve the ORA-01008 error.
Step 1: Check Your SQL Query
The first step in troubleshooting the ORA-01008 error is to review your SQL query and make sure that all of the placeholders (bind variables) have been assigned a value. For example, if your query looks like this:
SELECT * FROM employees WHERE hire_date > :date AND salary > :salary;
You need to make sure that both :date
and :salary
have been assigned values before executing the query.
Step 2: Verify Your Bind Variables
Next, you should verify that the values you’ve assigned to the bind variables match the data type and length specified in your query. For example, if you’ve assigned a string value to a bind variable that’s expecting a number, you’ll get the ORA-01008 error.
Step 3: Check Your Connection
If your SQL query and bind variables are correct, the next thing to check is your database connection. Make sure that you’re connected to the correct database and that your connection is still active.
Step 4: Try Rebinding Your Variables
If none of the above steps have resolved the ORA-01008 error, you can try rebinding your variables. This involves assigning values to your bind variables again, either through your application or by executing a PL/SQL block.
FAQ
What Causes the ORA-01008 Error?
The ORA-01008 error occurs when a SQL query has placeholders for bind variables (parameters), but not all of them have been assigned a value.
How Do I Fix the ORA-01008 Error?
To fix the ORA-01008 error, you should check your SQL query, verify your bind variables, check your connection, and try rebinding your variables.
Can the ORA-01008 Error Be Prevented?
Yes, the ORA-01008 error can be prevented by making sure that all of the placeholders in your SQL queries have been assigned a value before executing the query.
Other errors related to bind variables include ORA-01036 («illegal variable name/number») and ORA-01745 («invalid host/bind variable name»).
How Can I Debug SQL Queries with Bind Variables?
You can debug SQL queries with bind variables by using tools like Oracle SQL Developer or SQL*Plus, which allow you to step through your code and view the values of your variables at each step.

ORA-01008
ORA-01008: не все переменные связанны
Причина:
SQL оператор содержащий подстановочные переменные выполняется без связанности всех переменных. Все подстановочные переменные должны иметь подстановочные значения перед выполнением SQL оператора.
Действие:
В OCI, используйте OBIND или OBINDN вызов для подстановки требуемых значений.

Description
When you encounter an ORA-01008 error, the following error message will appear:
- ORA-01008: not all variables bound
Cause
You tried to execute a SQL statement that contained substitution variables where all variables were not bound.
Resolution
The option(s) to resolve this Oracle error are:
Option #1
In OCI, try using an OBIND or OBINDN call to substitute the values.
I am using Oracle SQL developer. I am running a query on employees table which is by default, having columns like
first_name, last_name, employee_id, email, phone_no, hire_date, job_id, salary, commission_pct, manager_id, department_id.
I am writting a report that displays the last name and salary of employees who earn more than an amount that the user specifies after a prompt.
If you enter 12000, it should display all employees earning more than 12000.
Eg: Salary_value: 12000.
My report is like this
select last_name, salary
from employees
where employees.salary>&sal;
But I am getting an error like this
ORA-01008: not all variables bound
01008. 00000 - "not all variables bound"
*Cause:
*Action:
Vendor code 1008
Clearly there is nothing in the cause section. I need help please. Thanks in advance.
BUT I can succesfully run it from Sql plus command line utility as well as I can run it as a *.sql file. But It is not working in case of a report. Why is this happening?
