Using JOIN to get results from two tables<\/h4>\n\n\n\n

This is PHP4 Code!<\/strong><\/em><\/span><\/p>\n\n\n\n

Example 1<\/h5>\n\n\n\n
\n\t$result = @mysql_fetch_array(@mysql_query(\"\n\t\tSELECT *\n\t\tFROM group_invitations\n\t\tJOIN member_profile\n\t\tON member_profile.user_id = group_invitations.user_id\n\t\tWHERE indexer = $indexer\n\t\t\"));<\/code><\/pre>\n\n\n\n
Example 2<\/h5>\n\n\n\n
$query = @mysql_query(\"\n  SELECT * FROM group_profile AS GP\n  JOIN group_membership AS GM ON GM.group_id = GP.indexer\n  WHERE (member_id = $user_id AND GP.indexer = $group_id) AND (GM.approved = 'yes' OR GP.public_private = 'public');\n\");\nif (@mysql_num_rows($query) == 0)<\/code><\/pre>\n\n\n\n
Using JOIN to get results from three tables<\/h4>\n\n\n\n
This is PHP4 Code!<\/strong><\/em><\/span><\/p>\n\n\n\n
Example 1<\/h5>\n\n\n\n
$query102 = @mysql_query(\"\n\tSELECT\tPP.indexer AS project_id,\n\t\t\t\tproject_name,\n\t\t\t\tproject_picture,\n\t\t\t\tproject_description,\n\t\t\t\tDATE_FORMAT(start_date, '%d-%m-%y') AS start_date,\n\t\t\t\tDATE_FORMAT(end_date, '%d-%m-%y') AS end_date,\n\t\t\t\tCONCAT_WS(' ', first_name, last_name) AS project_lead\n\tFROM project_profile AS PP\n\tJOIN group_membership AS GM ON GM.group_id = PP.group_id\n\tJOIN member_profile AS MP ON MP.user_id = GM.member_id\n\tWHERE PP.group_id = $group_id AND group_admin = 'yes'\n\tLIMIT $proj_set_limit, $proj_limit\");<\/code><\/pre>\n\n\n\n
Using GROUP BY To Get One Row Per Match<\/h4>\n\n\n\n
This is PHP4 Code!<\/strong><\/em><\/span><\/p>\n\n\n\n
Note – when using GROUP BY, if you also use ORDER BY it must come after the GROUP BY<\/p>\n\n\n\n
\t$sql_query\t= \"\n\tSELECT \n\t\ttable1.indexer\n\tFROM table1\n\tJOIN table2\n\tON table2.id = table1.id\n\tWHERE\n\t\ttable1.approved = 1 AND\n\t\ttable2.type = 10\n\tGROUP BY videos_usage.usage_video_id\n\t\";\n\t\/\/Note that if using WHERE, GROUP BY must be after it\n<\/code><\/pre>\n\n\n\n
