I want to know what is the error in this SQL query



I have updated the Query to


SELECT regexp_substr(a.NAME, '[^:]+$') AS emp_req
,a.COMPLETION_STATUS
,b.USER_TYPE
,b.display_name
FROM spt_result a
,spt_identity b
WHERE a.name LIKE 'Join%'
AND emp_req = b.display_name;



I want to fetch the user type from spt_identity table which is having completion status as error or success in spt_result table . the table spt_result contains


spt_result table


spt_result


NAME COMPLETION_STATUS
----------------------------------------------------------------
Add/Remove Role(s) for:kc051363(1503085327459) Error
Joiner:sk080281 Success



and spt_identity contains


spt_identity contains


USER_TYPE DISPLAY_NAME
-----------------------------
Parttime-Regular pt092101
Parttime-Regular rm088923
Vendor wl090918
Parttime-Regular ne091924
Vendor dh090040





How can we know what the error is in your SQL query if you don't tell us?

You have display_name as alias and actual column name. It may get confused.

Well I have changed it to :-select a.USER_TYPE,a.display_name,regexp_substr(b.NAME, '[^:]+$') as emp_name from spt_identity a,spt_task_result b where b.Name like 'Join%' and a.DISPLAY_NAME=b.emp_name; still the error showing as ORA-00904: "B"."EMP_NAME": invalid identifier 00904. 00000 - "%s: invalid identifier" *Cause: *Action: Error at Line: 5 Column: 162

When asking SQL related question, you should post SQLs you used to create the tables, and if the question concerns query result, SQLs to insert data. Without these information, you may have made a mistake when creating the table and we will never know. Please edit your question accordingly.

Bad habits to kick : using old-style JOINs - that old-style comma-separated list of tables style was replaced with the proper ANSI JOIN syntax in the ANSI-92 SQL Standard (more than 25 years ago) and its use is discouraged+

Join on occurrence of DISPLAY_NAME in NAME


DISPLAY_NAME


NAME


SELECT i.*
FROM spt_identity i
JOIN spt_result r ON INSTR(r.name, i.display_name) > 0
WHERE r.completion_status IN ('Error', 'Success')

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
