I need to update a field in a table in Oracle. Queries with only desired Columns Select customers.customer_name, Products.Product_type, Manufacturers.Manuf_name Currently we are running SQL Server 7 with SP1 installed on an NT box. RIGHT JOIN returns all the rows from the on the right side of the JOIN key word and only mantching rows from other tables. LEFT JOIN returns all the rows from the table on LEFT side of the JOIN key word and only matching rows from other tables. ON T3.CommonColumn = P.SomeCommonColumn (it will be a common column between table 3 and Projects OR Countries)īut you really need to look in joins as you can do different types of joins between tables, Hers in this example I used INNER JOIN which returns only the matching rows between all these tables, you could do LEFT JOIN or RIGHT JOIN. SELECT C.CountryName_Colummn, C.SomeOtheColumn. For example you want some data that is present in 3 different tables you would join them all three in one query something like this. SQL server rarely you would find all the required data in one table normally you would join 2-3 tables or more tables. No matter how many tables you have to join to get the required data as long as you can define the relationship between them table in your query it should work fine.

WHERE C.CountryName = 'UK' will return results only from UK.ĥ) In from Clause the Letters 'C' and 'P' are alias so we dont have to type full table names again n again, makes our code simpler and easier to read and debug. ġ) SELECT Clause you select the columns you need in your result set.ģ) ON Clause you define the relationship between the tables Say Projects table had a Column id_Country which refers to id_Country in Countries table defines the relationship between these two tables.Ĥ) After you have Selected the column list, Source of data (tables), Their relationship (On Clause) then you can filter the number of rows returning from you query, like you can something like id_Country For Example if you are trying to get A country's Name by using Country_ID in this Project table shown in your question, You could do something like SELECT C.CountryName_Colummn, C.SomeOtheColumn.
