Updating sql proceedure
If a new method or method arguments are specified without a preceding definition of type, Modify fails.
The UPDATE statement is used to change data within columns of a SQL Server data table.
Notice we used the primary key Sales Person ID to filter the row.
This makes is really easy to ensure we are updating exactly one row.
For instance, if a field is defined as CHAR(10) and you update the value ‘Kris’ into this column, then it will be padded with six spaces.
The value is changed to ‘Kris ‘You can handle errors when executing an UPDATE statement using a TRY…CATCH construct.
Note: The Sales Person ID generated for your table’s rows may be different than what is show in the exercises, since this primary key is auto generated.
The UPDATE statement is capable of updating more than one row. All rows returned via the WHERE clause criteria are updated.
Consequently, if you use Modify to change a stored procedure, be careful that you do not inadvertently introduce changes into the database.In addition, using Modify to enable a Data Window object to use stored procedures to update the database when it is not already using stored procedures requires that the type qualifier be specified first.Calling the type qualifier ensures that internal structures are built before subsequent calls to Modify.Suppose every Sales Person whose ID is less than 10031 worked in Saline.To update the rows to reflect this we could use this UPDATE statement: Which results in the following row modifications: The UPDATE statement is complex and there are many elements to consider.
