passing PHP variable to sql query in oci_parse

Hi everyone,

I'm currently working on a PHP project and I'm facing an issue with passing a PHP variable to my SQL query using oci_parse. I have a variable called $userId and I want to use it as a parameter in my SQL query. Here's an example of what I'm trying to achieve:

$userId = 12345;

$query = "SELECT * FROM users WHERE user_id = :userId";
$statement = oci_parse($connection, $query);
oci_bind_by_name($statement, ":userId", $userId);

But whenever I execute the code, I'm not getting any results. I have double-checked the value of $userId, and it seems to be correct. I'm not sure what I'm doing wrong here. Can anyone help me figure out how to pass a PHP variable to a SQL query in oci_parse correctly?

Thanks in advance for your assistance!

Hey fellow developers,

I recall encountering a similar hiccup in the past when working with oci_parse and passing PHP variables to SQL queries. One potential reason you might not be getting any results is because of a mismatch in the data type conversion.

Check if the data type of the 'user_id' column in your Oracle database aligns with the data type of the $userId variable. For example, if the 'user_id' column is of type NUMBER, ensure that $userId is explicitly cast as a float or integer.

Additionally, it's critical to confirm that the oci_bind_by_name function is properly binding the variable. Just to be sure, cross-verify if the variable name in oci_bind_by_name matches the parameter name (":userId") specified in your SQL query.

Lastly, double-check the validity of the connection to the Oracle database before executing the query. A small oversight in the connection establishment might be the hidden culprit behind the issue.

I hope these suggestions aid in resolving the challenge. If you have any further queries, feel free to reach out. Happy coding!


Hey there!

I've encountered a similar issue before when working with oci_parse and passing PHP variables to SQL queries. In my case, the problem was with the data type mismatch between the PHP variable and the Oracle database column.

Make sure that the data type of the column you're comparing the $userId with in the WHERE clause is the same as the data type of $userId. For instance, if user_id is a numeric column, ensure that $userId is an integer.

In addition to that, it might also be helpful to check if your oci_bind_by_name call is correctly binding the variable. Double-check that the variable name in oci_bind_by_name matches the parameter name in your query, which in this case is ":userId".

Finally, also verify that the connection to the Oracle database is established properly before executing the query.

I hope these suggestions help you resolve the issue. Let me know if you have any further questions or if there's anything else I can assist you with!


Hi there,

I completely understand the frustration you're experiencing while trying to pass a PHP variable to an SQL query using oci_parse. I've encountered a similar issue before, and one possible reason for not getting any results could be related to the use of bind variables.

In my case, I discovered that when using bind variables, it's crucial to make sure the names of the bind variables in oci_bind_by_name match exactly with the parameter names in your SQL query. Even a small typo or case sensitivity can cause the query to fail.

Another aspect worth checking is whether you have properly established the connection to the Oracle database. It's important to ensure that the connection is successful before executing the query.

Lastly, if you're still facing difficulties, I would suggest checking the actual SQL query itself. You can try echoing the query string just before oci_parse to see if it is constructed correctly and if the bind variable is properly included.

I hope these insights help you overcome the issue you're facing. If you have further questions or need more assistance, don't hesitate to ask. Good luck with your PHP project!
