4. Abstract
CA IDMSTM SQL allows you to access CA IDMSTM databases directly with SQL DML, regardless of whether the databases were originally defined as SQL or network data. For certain database structures or application needs, utilizing routines may make your implementation more efficient and robust; in rare cases they may be required. Part 1 of this 3-part series covered an overview of routines: table procedures, procedures, called procedures, and functions. The series continues in this webcast by exploring table procedures in depth, with details on how to design, code, and deploy them. It will also address how to use CA IDMSTM SQL Quick Bridge to create table procedures, including a live demo of the product.

9. SQL Routines: Review
How Table Procedures Compare To Other Routines

10. What is a Routine? Think PIP A routine is a user-written
Program or dialog which is
Invoked directly by the SQL engine when the routine is
referenced in SQL DML; the call is managed by
Parameters specified either as part of the definition or as
part of a standard set of arguments included in the call.
Implications
Involves user-written code, must be tested and optimized
Code must be written to interface successfully with engine
Parameter values have great impact
August 5, CA IDMS™ Modernization Series:Table Procedures and CA IDMS™ SQL QuickBridge Copyright © 2008 CA

11. CA IDMS Routines Invoked by SQL engine when referenced in SQL DML
Definition specifies external routine name
Parameters passed and returned
Routine performs I/O and/or processing
Possible iterations for table procedure
Three types of SQL routines
Table procedure
Procedure
Function

When direct SQL DML access does not meet needs
When views do not meet needs to simplify complex SQL DML
Analyze performance requirements
Highly variable cardinality and statistics
Sophisticated security, i.e. row level, external dependencies
Reduce client/server communication
To standardize common complex processes
Not required for SQL access to some network structures
Fixed occurs elements
Update/Delete rows where no foreign key defined (ROWID)
August 5, CA IDMS™ Modernization Series:Table Procedures and CA IDMS™ SQL QuickBridge Copyright © 2008 CA

15. When to Use Table Procedures (cont.)
Required for SQL access to some network database structures
Bill of Material
Occurs depending on elements
Multi-member sets
Insert rows in sets and no foreign keys defined
Structures requiring special, complex processing (REDEFINES)
Within a single SQL transaction
Transparently consolidate data from different databases
Access segmented databases
Access remote data (distributed across nodes)
August 5, CA IDMS™ Modernization Series:Table Procedures and CA IDMS™ SQL QuickBridge Copyright © 2008 CA

16. Table Procedures
Structure and Coding

17. Implement Table Procedure: CrEATE
Create statement: define table procedure in catalog
Write the routine
COBOL, Assembler, PL/I
SQL DML, network DML, neither, or both
Must create access module if using SQL DML
Enable security
Add program definition to system (DC/UCF)
Test and debug
Efficiency check: optimize & tune
August 5, CA IDMS™ Modernization Series:Table Procedures and CA IDMS™ SQL QuickBridge Copyright © 2008 CA

18. Create Statement: Define In The Catalog
Schema and name
External name: associates table procedure with load module
Parameters: Name, SQL data type, optional default
Language: Assembler, COBOL, PL/I
Protocol IDMS
Local and global work areas
Default database current
Other attributes: estimates, system/user mode, etc.
August 5, CA IDMS™ Modernization Series:Table Procedures and CA IDMS™ SQL QuickBridge Copyright © 2008 CA

19. Create Table Procedure: Example
CREATE TABLE PROCEDURE DEMOEMPL.TBLPROC
( E_ID UNSIGNED NUMERIC(4),
E_NAME CHARACTER(25),
E_ADDRESS CHARACTER(46) )
EXTERNAL NAME TPROCPGM
ESTIMATED ROWS 1000
ESTIMATED IOS 100
USER MODE
LOCAL WORK AREA 800
GLOBAL WORK AREA 1200 KEY SHR1
TRANSACTION SHARING DEFAULT
DEFAULT DATABASE CURRENT
TIMESTAMP ;
Black is required keywords; grey are user-supplied required parms; blue are optional parms …
USER MODE
Specifies the table procedure should execute as a user-mode application program within CA IDMS. This is the default value unless SYSTEM MODE is specified.
SYSTEM MODE
Specifies the table procedure should execute as a system-mode application program. To execute as system mode, the program must be:
Written in Assembler
Fully reentrant
LOCAL WORK AREA
CA IDMS allocates a local storage area on the first call to a table procedure for each SQL statement within a transaction or for a set of SQL statements which are related through reference to the same cursor (OPEN, FETCH, CLOSE, positioned UPDATE, and DELETE statements are related through a cursor). The same local storage area is passed to the table procedure for all calls for one statement or related statements. When the SQL statement has completed execution or when the cursor is closed, the local work area is released. Note: If you do not code a LOCAL WORK AREA clause, the default local storage size is 1024 bytes.
GLOBAL WORK AREA
CA IDMS allocates a global storage area once within a transaction and retains it until the transaction terminates.
key-id
Specifies the one- to four-character identifier for the global storage area. Advantage CA-IDMS passes the same piece of global storage within a transaction to all SQL routines that have the same global storage key. If you do not specify a storage key, Advantage CA-IDMS allocates each table procedure its own global storage area, which is not used for any other routine within the transaction.

Code must set output parameters
SQLSTATE is required, controls when iteration is stopped
00000 -- Indicates success 
01Hxx -- Indicates a warning
02000 -- Indicates no more rows
38xxx -- Indicates an error
Values, indicators (0, -1) required to return row
Customized error messages optional
August 5, CA IDMS™ Modernization Series:Table Procedures and CA IDMS™ SQL QuickBridge Copyright © 2008 CA

23. Write The Table Procedure: Work Areas
Linkage Section in COBOL
Local work area – can’t exceed size in definition
Separate area for each scan
Preserved over calls within scan (DML)
Database position, input parameters, etc
Global work area– can’t exceed size in definition
Shared by procedures and scans in transaction
Subschema control
Has an associated key
August 5, CA IDMS™ Modernization Series:Table Procedures and CA IDMS™ SQL QuickBridge Copyright © 2008 CA

24. Write The Table Procedure: Work Areas
COBOL working storage contents not retained across calls
Values on first request for a scan might have been altered in prior request
Working-storage section allocation and initialization varies
Local mode vs. within the DC/UCF address space
Concurrent scans are being processed
Use working storage only for:
Constants the SQL routine will never change
Variables initialized and used within single call to program
Other variables must be defined in local or global work area

32. Table Procedures
Run-Time

33. Invoking a Table Procedure
SQL DML statements
Reference in FROM, like view or table
Use in any DML statement
Program DML independent of SQL DML
Parameter values passed dependent on type of DML
Possible to use a CALL statement
For CA IDMSTM Server 5.0, from JDBC procedure call
For CA IDMSTM Server r16, from ODBC procedure call
“Where” filters output from table procedure
Not required; no “where” returns all occurrences
it is possible to invoke a table procedure using an SQL CALL statement by setting CallSelect = 1 either in the Windows registry, caidms.cfg file or in a Java properties file.  Generally a client would only want to do this if they had changed the SYSCA.ACCESSIBLE_PROCS view to include type “R” (table procedures) in addition to “P” (procedures).  The difference is that then the CALL statement will be treated exactly like a SELECT in that a result set will be returned which can be fetched like any other result set.  Ordinarily, a CALL statement causes input/output or output parameters to be filled in without the program having to open a cursor or fetch data. 
In Server r16, we implemented this capability in ODBC (it existed in JDBC in r5.0).  In talking with Dave Ross, the CallSelect feature was something he thought might be handy for compatibility purposes, but I don’t know that any client has actually used it.  It’s not something we encourage, but it is there if anyone needs it.
