I have a lot of SQL with named parameters that I need to be able to execute in SQL Developer. For SQL where the parameters are scalar values it's easy to paste the SQL into a worksheet and SQL Developer will prompt me (in a dialog with the title "Enter Binds") to enter the parameter values. But for cases where the parameter needs to hold multiple values, like this: select count(*) from foo where foo.id in (:ids) where, say, :ids needs to be replaced with 1,2,3 so that the query executed is select count(*) from foo where foo.id in (1,2,3) I try entering the values into the dialog (and I've

Is it possible in Oracle SQL developer to do something like this CREATE FUNCTION fnCheckValid(accountidd IN NUMBER) RETURN NUMBER IS retval NUMBER(4,0); BEGIN SELECT COUNT(accountid_fk) INTO retval FROM tbl_AccountAuthentications WHERE accountid_fk = accountidd; RETURN(retval); END; / ALTER TABLE tbl_AccountAuthentications ADD CONSTRAINT chkCheckvalid CHECK(fnCheckValid(accountid_fk) <= 1); The error i keep getting is Error starting at line 999 in command: ALTER TABLE tbl_AccountAuthentications ADD CONSTRAINT chkCheckvalid CHECK(fnCheckValid(accountid_fk) <= 1) Error report: SQL Error: ORA

I'm looking at a client application which retrieves several columns including ROWID , and later uses ROWID to identify rows it needs to update: update some_table t set col1=value1 where t.rowid = :selected_rowid Is it safe to do so?

in sql developer--preference Environment--encoding is already set to 'UTF-8' Code Editor--fonts was set to 'Verdana' Database--NLS--Language was set to 'American' The data in db was written by Java in UTF-8 encoding (95% percent sure） What else I need to do to make it displayed correctly?

We have big database with a lot of stuff and I want to use version control (Git) to manage changes. There are a lot of articles how to do it step by step but one piece is missing for me. Is there standard or recommended way for file structure of whole database (data excluded) and how it can be obtained from existing database?

But they suggest that each file should be selected and saved to file system separately. Is there way to export/import all
