For example, if you had to loop over an insert statement; try changing it to creating XML with the same loop, then having SQL parse the XML into a temporary table and doing your insert via a select statement on the temporary table.
It is not a good idea to hold multiple key values in the same column. Shop No Results: Shop No, Shop Name, Goods Name101, Sun, Banana102, Moon, Banana102, Moon, [email protected], Sorry for the long comment.Having multiple keys in a column leads to data integrity issues (like will banana exist in your database, if the links to shops 101 & 102 are removed? I would suggest changing it into 3 tables: Table A (Goods)Goods ID, Goods Name1, Banana2, Apple Table B (Shops)Shop No, Shop Name101, Sun102, Moon Table C (Shop Goods or Inventory) "Join Table"ID, Goods ID, Shop No1, 1, 1012, 1, 1023, 2, 102This is the basic setup for a many-to-many relationship between two entities (tables). I realize that I could of answered the question directly, and I don't want to hi-jack your blog comments with essay responses of my own; however I have seen too many people fall into the trap of getting a table's rows to describe more than one entity, and am hoping to help with an alternative approach. I been google for find the answer people just siad like you just told not suggest to save mutiple value in same column.the schema and exist data just save like this format.. which old Data exist many data row already)Table ASHOPNO GOODS101`102 BANANAif I really need to find a way to retrieve the SHOPNAME.the best way by other code language not SQL? @JD, I can understand the pain of not being able to change the schema and I know that a well structured schema saves you from a lot of headaches.By adding the join table you can then manage the relationships with simple Insert/Update/Delete statements. Goods Name FROM Goods AS AINNER JOIN Shop Goods AS CON A. Personally, I would flat-out refuse to work with this type of database schema, opting to volunteer rewriting the structure and creating ETL (Extract Transfer Load) scripts to move the data to the new schema.Created By = 'jsmith'--SELECT * FROM Completed Requirement cr INNER JOIN vw Requirement List rl ON cr. When i ran the whole statement i was very surprised that it affected 28080 rows.Luckily it was on a test system, but i would have felt comfortable running this in production after verifying the select results. Completed Requirement ID = 90271 ) UPDATE cte SET Created By= 'jsmith'Thanks for all your help, Dennis @Ben, I believe it is required to use aliases in the join section of a join-based update query, however Dennis was attempting to update the alias.hi thank you Andrew Bauer I just tried to convince them to let me change the schema , but ... IT'S NOT PROBLEM FOR ME TO JOIN ECRPYHS WITH ECRHDHSTHEN I HAVE PROBLEM TO JOIN WITH PAYINFO ... OR GIVE ME A EXAMPLE TO KNOW HOW TO DOTHANK YOU VERY MUCH!! D, If you can join ECRPYHS and ECRHDHS, it should be easy to join PAYINFO as well. You can then tell gridview to automatically generate columns with the tag Auto Generate Columns="True". S - Sorry for the long post.--------------------------------SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOCREATE PROCEDURE [dbo].[sp_Crosstab] @DBFetch varchar(4000), --specifies the set of data to summarize @DBWhere varchar(2000) = NULL, --is optional, specifies a WHERE clause to filter the data specified by the @DBFetch parameter @DBPivot varchar(4000) = NULL, --is optional, specifies the column names to appear in the result set @DBField varchar(100), --specifies the column containing the data that becomes result set column names @PCField varchar(100), --specifies the column to be aggregated.
in vain , for some reason they just want this kind of schema to save data..maybe I will try the way ( use other code languae ) to get the result I need thanks for your patient and suggestion !! You can then configure the columns via sub routines if necessary. Common syntax for sp_crosstab is; EXEC [dbo].[sp_Crosstab] @DBFetch = 'table or view to be cross tabbed - can be a temp table', @DBField = 'Field to become column headings - PYID in your case', @PCField = 'Field to be totaled - HASTOTAL in your case', @PCBuild = 'COUNT, SUM, MIN, MAX or AVG'I'm not sure where I get this procedure from, so I'm not sure who to give credit to. @PCBuild varchar( 20), --specifies the aggregation to be performed (COUNT, SUM, MIN, MAX or AVG) @PCAdmin varchar( 20) = NULL, --is optional, specifies a result set column name to represent null values @DBAdmin int = 0, --is optional, specifies whether any additional columns should be added to the result set for totals @DBTable varchar(100) = NULL, --is optional, specifies a table name for the result set @DBWrite varchar(160) = NULL, --is optional, specifies a database name for the @DBTable parameter @DBUltra bit = 0 --is optional, specifies whether the result set table (if specified) should be dropped (if it already exists) before saving the result set.
If anyone is interested in the XML CRUD stored procedure, let me know and I will see if I can dig it out of one of my past projects.
I am on holidays in another state at the moment, so I can not get my previous work; however here is an approach that is a little bit less verbose than my example: I get back, I will post my example.
Anyway, enough talk, let's take a look at this in action.
Since I don't have any tables ready to play with, I have created three in-memory SQL tables: boy, girl, and relationship.
Also the result you are after is achieved with an inner join (however over multiple rows): SELECT B. In my opinion, a couple of days for writing a schema/ETL scripts and changing code that my already rely on the current structure, is much better to creating a hack that will cause you troubles down the line.
