Why do I have ORA-00904 even when the column is present?

问题

I see an error while executing hibernate sql query.

java.sql.SQLException: ORA-00904: "table_name"."column_name": invalid identifier

When I open up the table in sqldeveloper, the column is present.

The error is only happening in PROD, not in DEV.

What should I check?

回答1:

It could be a case-sensitivity issue. Normally tables and columns are not case sensitive, but they will be if you use quotation marks. For example:

create table bad_design("goodLuckSelectingThisColumn" number);

回答2:

Oracle will throw ORA-00904 if executing user does not have proper permissions on objects involved in the query.

回答3:

This happened to me when I accidentally defined two entities with the same persistent database table. In one of the tables the column in question did exist, in the other not. When attempting to persist an object (of the type referring to the wrong underlying database table), this error occurred.

回答4:

Write the column name in between DOUBLE quote as in "columnName".

If the error message shows a different character case than what you wrote, it is very likely that your sql client performed an automatic case conversion for you. Use double quote to bypass that. (This works on Squirrell Client 3.0).

回答5:

It is because one of the DBs the column was created with " which makes its name case-sensitive.

Oracle Table Column Name : GoodRec Hive cannot recognize case sensitivity : ERROR thrown was - Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "GOODREC": invalid identifier

Solution : Rename Oracle column name to all caps.

回答6:

check the position of Column annotation in java class for the field For Example,consider one table with name STUDENT with 3 column(Name,Roll_No,Marks).

Then make sure you have added below annotation of column before Getter Method instead of Setter method. It will solve ur problem @Column(name = "Name", length = 100)

**@Column(name = "NAME", length = 100)
public String getName() {**
    return name;
}

    public void setName(String name) {
    this.name= name;
}

Have you compared the table definitions in Prod and Dev?

And when you are running it in SQL Developer, are you running the query in Prod (same database as the application) and with the same user?

If there are some additional columns that you are adding (using an alter command) and these changes are not yet promoted to prod, this issue is possible.

Can you post the definition of the table and your actual Query?

回答8:

I use Toad for Oracle and if the table is owned by another username than the one you logged in as and you have access to read the table, you still may need to add the original table owner to the table name.

For example, lets say the table owner's name is 'OWNER1' and you are logged in as 'USER1'. This query may give you a ORA-00904 error:

select * from table_name where x='test';

Prefixing the table_name with the table owner eliminated the error and gives results:

select * from

回答9:

Check the username credential used to login to the database. (persistence.xml ??). The problem mostly is, the username\password used to login to the database, does not have visiblity to the object (table_name in this case). ( try logging in to sql developer, using the same username\password available in your data source)
