Question

here i was past my sql query.
any body know GROUP_CONCAT alternative function so let me know ?
SQL Error :
<h1>A Database Error Occurred</h1>
<p>Error Number: 1140</p>
<p>In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'smartsaver.ud.id'; this is incompatible with sql_mode=only_full_group_by</p>
SQL Command :
SELECT ud.id, ud.url, d.document_name, d.d
GROUP_CONCAT(LEFT(REPLACE(url, "document", "thumb"), CHAR_LENGTH(REPLACE(url, "document", "thumb")) - LOCATE(".", REVERSE(REPLACE(url, "document", "thumb")))), ".", "png")
ud.document_url
END as new_url, CASE WHEN ud.type = 1 THEN "Image" WHEN ud.type = 2 THEN "Video" WHEN ud.type = 3 THEN "File" WHEN ud.type = 4 THEN "Text" ELSE "" END as type, d.added_on, ud.type as document_type
FROM tbl_uplaod_document ud
JOIN tbl_document d ON d.id = ud.document_id
LEFT OUTER JOIN tbl_document_project_relation pr
ON pr.document_id = ud.document_id
WHERE ud.is_active = 1
AND d.is_active = 1
AND ud.user_id = 1
AND ud.document_id = 116
LIMIT 10

Answer 1

#dev5 Your code to hard to read
Expression #1 of SELECT list is not in GROUP BY clause and contains non aggregated column 'smartsaver.ud.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by.
will be simply solved by changing the sql mode in MySQL by this command:
SET GLOBAL sql_mode=(SELECT REPLACE(##sql_mode,'ONLY_FULL_GROUP_BY',''));
Thank You :-)

You have a select with an aggregation function. That makes the query an aggregation function. But there is no group by. Happily, MySQL now generally returns an error in this case.
Earlier versions of MySQL allowed a malformed query such as your using the default settings. It would return values for the unaggregated columns from arbitrary rows. The default settings have changed to generate an error.
You should add a group by for all non-aggregated columns in the select:
group by ud.id, ud.url, d.document_name, d.d, . . .
Your code is rather hard to read, so it is hard to pick out the unaggregated columns.
