Update Query with INNER JOIN between tables in 2 different databases on 1 server

由 余生颓废 提交于 2019-11-28 07:08:42
Need some SQL syntax help :-) Both databases are on the same server db1 = DHE db2 = DHE_Import UPDATE DHE.dbo.tblAccounts INNER JOIN DHE_Import.dbo.tblSalesRepsAccountsLink ON DHE.dbo.tblAccounts.AccountCode = DHE_Import.tblSalesRepsAccountsLink.AccountCode SET DHE.dbo.tblAccounts.ControllingSalesRep = DHE_Import.dbo.tblSalesRepsAccountsLink.SalesRepCode I can do a query in Access with linked tables with similar syntax - BUT SQL doesn't like it. I'm sure it's a simple issue :-D Thanks! jerry You could call it just style, but I prefer aliasing to improve readability. UPDATE A SET

Insert using LEFT JOIN and INNER JOIN

由 谁都会走 提交于 2019-11-28 04:20:30
Hey all i am trying to figure out how to go about inserting a new record using the following query: SELECT user.id, user.name, user.username, user.email, IF(user.opted_in = 0, 'NO', 'YES') AS optedIn FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id ORDER BY user.id; My INSERT query so far is this: INSERT INTO user SELECT * FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id; However, i am not sure how to do VALUE('','','','', etc etc) when using left and inner joins. So what i am looking to do is this: User table: id | name | username |

SQL Server - INNER JOIN WITH DISTINCT

How to determine what is more effective: DISTINCT or WHERE EXISTS?

由 点点圈 提交于 2019-11-28 00:08:24
问题 For example, I have 3 tables: user , group and permission , and two many2many relationships between them: user_groups and group_permissions . I need to select all permissions of given user, without repeats. Every time I encounter a similar problem, I can not determine which version of a query better: SELECT permisson_id FROM group_permission WHERE EXISTS( SELECT 1 FROM user_groups WHERE user_groups.user_id = 42 AND user_groups.group_id = group_permission.group_id ) SELECT DISTINCT permisson
