I am using laravel framework for developing API's ,i have one query that is executed without where condition without any error i need to execute with where condition but it's throwing an error
query
select count(*) as aggregate
from `users`
left join `books` on `books`.`book_id` = `books`.`id`
where `access_id` = 5054
SQL Error [1052] [23000]: Column 'access_id' in where clause is
ambiguous
after searching google i got something we have to specify reference of a table name , i added reference name like this where users.access_id =5054 but it's throwing an error like unknown column but in my db i have that column in both users and books table
The problem is its consider as a column so that's why syntax error is coming,try following way it will resolve your problem
select count(*) as aggregate
from `users`
left join `books` on `books`.`book_id` = `books`.`id`
where `users`.`access_id` = 5054

I am trying to update the SUIDMatches column of table1_orig_namesplits table based on number of matches it find in the master_table using the following update statement.
But I am getting an "Error Code: 1054. Unknown column 'al.source_id' in 'on clause'" error.
UPDATE test.table1_orig_namesplits al
SET al.SUIDMatches = (
SELECT count(distinct v.SUID)
FROM test.master_table v
JOIN test.table1_orig a ON al.source_id = a.id_names
WHERE al.name_first = v.FirstName
AND al.name_last = v.LastName
AND a.date_of_birth_dt = v.BirthDate_dt );
There is a source_id column in the table1_orig_namesplits table is matched with the id_names column of table1_orig.
Can anyone please suggest how to fix this update statement?
The problem appears to be that the sub-query attempts to join test.table1_orig to test.master_table using a column from test.table1_orig_namesplits which is not part of the join.
For further testing / analysis some sample data would be helpful, but the basic idea is that you'll either have to join to al in the subquery, or take a different approach.
I know SQL in SQLite is not completely implemented the same way as in MySql. My problem with the following queries is, that they are not compatible and I like to avoid a conditional if <DBMS> ... else
SQLite query
UPDATE sorties SET state = '#'
WHERE `key` IN (
SELECT `key` FROM sorties
INNER JOIN reports AS r
ON r.sortieId=sorties.`key`);
Error on MySQL:
SQL Error (1093): Table 'sorties' is specified twice, both as a target for 'UPDATE' and as a separate source for data
MySQL query (adapted from here)
UPDATE sorties AS s SET s.state='#'
WHERE s.`key` IN (
SELECT t.sortieId FROM (
SELECT r.sortieId AS sortieId
FROM reports AS r
INNER JOIN sorties AS sort
ON sort.`key`=r.sortieId)
AS t);
Error on SQLite:
SQLiteManager: Likely SQL syntax error: UPDATE sorties AS s SET s.state='#'
WHERE s.key IN ( SELECT t.sortieId FROM (
SELECT DISTINCT r.sortieId AS sortieId
FROM reports AS r
INNER JOIN sorties AS sort
ON sort.key=r.sortieId) AS t); [ near "AS": syntax error ]
Exception Name: NS_ERROR_FAILURE
Exception Message: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [mozIStorageConnection.createStatement]
I can't figure out how to make this queries work on both systems equally!
All I want to have is, that each state of sorties must be '#' when it's key can be found in reports.sortieId.
Maybe there is a different approach for this?
Thank you
The first command reads the key value from the sorties table in the subquery, and then checks whether those key values exist in the sorties table in the outer statement. That check is superfluous; you can just compare the values to the ones in reports directly:
UPDATE sorties
SET state = '#'
WHERE key IN (SELECT sortieId
FROM reports);
As for the second command, SQLite does not support aliasing a table used in INSERT/UPDATE/DELETE because those commands work only on a single table. You can just remove the AS s and replace s with sorties everywhere.
Hello first time using Oracle SQL Developer and I'm trying to do a select join on two tables and I get the error "ORA-01722: invalid number". What is causing this error?
All of the Google results point to creates/inserts that are invalid.
Here is my query, both CUSTNO and ARCUSTO_ID are of type NUMBER(15,0)
SELECT
ARCUSTO.COMPANY, SHIP_TO.ADDR1
FROM
ARCUSTO
INNER JOIN
SHIP_TO ON ARCUSTO.CUSTNO = SHIP_TO.ARCUSTO_ID;
I know there is more than one question out there that matches this, but I am relatively new to mysql, and I can't seem to make this work using sub quests or the USING key word, plus I find the mysql on line docs a complete mystery.
I started trying to build my DELETE query using a SELECT query as my base and was able to get all the rows that I wanted to delete:
select *
from writings_tags_link
join writing_tags on writing_tags.id = writings_tags_link.tag_id
where writing_tags.tag = 'tag one'
and then just replaced select all with DELETE so:
delete
from writings_tags_link
join writing_tags on writing_tags.id = writings_tags_link.tag_id
where writing_tags.tag = 'tag one'
I gather from both the error message and from other similar posts that you can't use 'ON' to join tables in a delete query, you have to use USING or a sub query. The query I built with USING returns a really strange error, first the query:
DELETE
FROM writings_tags_link
USING writing_tags_link INNER JOIN writing_tags
WHERE writing_tags.id = writings_tags_link.tag_id
AND writing_tags.tag ='tag one'
error:
#1109 - Unknown table 'writings_tags_link' in MULTI DELETE
This table does exist, obviously, my original select query returned the desired results. Any help / explanation would be so very appreciated!
Please keep in mind, I'm only trying to delete the data in the linking table.
Your information is incorrect about requiring the use of the USING keyword in DELETE syntax when using JOINs - the documentation provides examples in the multi-delete section:
DELETE wtl
FROM WRITINGS_TAGS_LINK wtl
JOIN WRITING_TAGS wt ON wt.id = wtl.tag_id
WHERE wt.tag = 'tag one'
I'm having an issue getting a COUNT() from a SQL query using Zend_Db_Table_Select, and I think it may be a possible bug because the SQL it should be generating actually works. Here's the Zend Select Query: ($this is a Zend_Db_Table, renamed to table1 in this example)
$select = $this->select();
$select->setIntegrityCheck(false);
// Select Count
$select->from($this, array("COUNT(*) as 'COUNT'"))
->joinLeft('users', 'table1.userID = users.userID')
->joinLeft('table2', 'users.anotherKey = table2.anotherKey');
// Add Where clause after join
$select->where('users.anotherKey = ?', $anotherKeyValue);
This gives the error:
SQLSTATE[42000]: Syntax error or access violation: 1140
Mixing of GROUP columns (MIN(),MAX(),COUNT(),...) with no GROUP columns is
illegal if there is no GROUP BY clause`
However, this query...
SELECT COUNT(*) AS 'count' FROM table1
LEFT JOIN users ON table1.userID = users.userID
LEFT JOIN table2 ON users.anotherKey = table2.anotherKey
WHERE users.anotherKey = [anotherKeyValue]
...returns the expected results with no errors when run against the database. Any ideas whats going on, why the error, and how to get around it?
have you tried to see actual query, that zend_db produce?
