Question

I’m new to using Oracle SQL Developer and to using an Oracle DB (have mainly used MySQL before)

I’m trying to do something like:

select * from content_definition where content_id = "hhhh233";

Where content_id is:

VARCHAR2(1000 BYTE)

But am getting:

ORA-00904: "hhhh233": invalid identifier
00904. 00000 -  "%s: invalid identifier"
*Cause:    
*Action:
Error at Line: 1 Column: 52

I’m not really understanding why this isn’t working as I used to do queries like this all the time with MySQL. I have been searching on this but nothing seems to be for my specific use case. I would appreciate if anyone can set me in the right direction on this. Thanks

You need to use single quotes for character data; double quotes signify identifiers and aliases:

select * from content_definition where content_id = 'hhhh233';
