Data Types and RunSQLSTM

Agenda Lab 1 demo this week –Bring your lab notes! Create your own Data Types Label on Authority RunSQLstm

Create your own Data Types Also known as User-Defined Types (UDTs) Used to create specific versions of standard data types Eg: Create Distinct Type CustIDType as Dec(7, 0) with Comparisons Creates a data type called CustIDType that is a 7 digit decimal. The ‘with Comparisons’ allows the use of >, =, etc with this data type

Create a new Customer table with a unique Customer Code using a UDF

Label on Table or view – description Column –Column Heading (20 characters per line) –Text description

Authorization Terms See Chapter 9, figure 9.1 from text book

Object Ownership WRKOBJOWN –Displays all objects that you own The owner automatically has *ALL authority to an object Every object must have an owner

If you’re not the owner Then you can have –Explicit authority –Part of an authorization list –Belong to a group profile –Part of *PUBLIC

EDTOBJAUT Edit Object Authority

See figures 9.3 and 9.4a in text book

SQL Authorities Table or view Distinct type Stored procedure of UDF SQL Package not collections or libraries

SQL Authorities Grant –Tables and views GRANT action1, action2, action3, etc ON table1, table2, view1, etc TO user1, user2, user3 –The ALL keyword can be used to allow authority to all actions REVOKE removes authority, by action

Grant Read and Update authority to DA544A40 for the table Customer

Grant Usage Grants usage of user defined distinct types to other users GRANT USAGE ON DISTINCT TYPE DOLLAR TO DA544A40 Gives DA544A40 use of the distinct type DOLLAR REVOKE USAGE revokes authority

Grant Execute Grants another use the ability to execute a UDF GRANT EXECUTE ON FUNCTION EFFECTIVERATE TO DA544A40 REVOKE EXECUTE removes the authority

RUNSQLSTM

Executes a list of SQL statements which are stored in a Source Physical File Each Statement must end in an ; (semi- colon) Results from executing the RUNSQLSTM command are stored in a spooled file (WRKSPLF)

Creating a Source Member for RUNSQLSTM Create the source physical file (CRTSRCPF) Clear your session (option 3 from session attributes) Test all commands in that you want to include in your source member Upon exit, type option 4 – Save Session in Source File –Enter the file, library and member parameters of the Change Source File screen Edit the source physical file member using SEU or Websphere –Comments start with – (two dashes) –Commands must end with an ‘;’

Executing SQL statements using RUNSQLSTM If the SQL statements are stored in the Source PF, DA544A40/QSQLSRC and the source member RUNTST RUNSQLSTM SRCFILE(LAURIN/QSQLSRC) SRCMBR(RUNTST) NAMING(*SQL) –Naming convention must be changed to *SQL if the sql convention, library.object is used

Use WRKSPLF to view the resulting Spooled File
