SQL view listing Binding Directory information

All I wanted was a quick way to check which Binding Directories contain a certain service program. Included in IBM i 7.5 and 7.4 TR6 is a SQL View that can provide me with the information I desire.

If I wanted to see which Service Programs and Modules are contained within a Binding Directory I would use the Work With Binding Directory Entries command, WRKBNDDIRE:

WRKBNDDIRE BNDDIR(MYLIB/TEST)

Which shows the following:

                     Work with Binding Directory Entries

Binding Directory:   TEST           Library:   MYLIB

Type options, press Enter.
  1=Add   4=Remove


Opt   Object       Type      Library      Activation   Date         Time
                                                   
      MODULE1      *MODULE   *LIBL                     06/08/21     18:15:28
      SRVPGM1      *SRVPGM   *LIBL        *IMMED       06/08/21     18:34:10
      SRVPGM2      *SRVPGM   *LIBL        *DEFER       06/08/21     18:41:08

The Binding Directory Information View, BINDING_DIRECTORY_INFORMATION, is found in the library QSYS2. It contains the same columns the screen does. If I run the following SQL statement to return the information for the same Binding Directory:

SELECT ENTRY_LIBRARY,ENTRY,ENTRY_TYPE, 
       ENTRY_ACTIVATION,ENTRY_CREATE_TIMESTAMP
  FROM QSYS2.BINDING_DIRECTORY_INFO 
 WHERE BINDING_DIRECTORY_LIBRARY = 'MYLIB'
   AND BINDING_DIRECTORY = 'TEST'

The results look the same as the output from WRKDIRE.

ENTRY_            ENTRY    ENTRY_      ENTRY_CREATE_
LIBRARY  ENTRY    _TYPE    ACTIVATION  TIMESTAMP
-------  -------  -------  ----------  -------------------
*LIBL    MODULE1  *MODULE  <NULL>      2021-06-08 18:15:28
*LIBL    SRVPGM1  *SRVPGM  *IMMED      2021-06-08 18:34:10
*LIBL    SRVPGM2  *SRVPGM  *DEFER      2021-06-08 18:41:08

Let me go back to my original need: a quick way to find all of the Binding Directories a particular service program is in. Using BINDING_DIRECTORY_LIBRARY my SQL statement would be as simple as:

01  SELECT BINDING_DIRECTORY_LIBRARY AS "Bnd lib",
02         BINDING_DIRECTORY AS "Bnd dir",
03         ENTRY_LIBRARY AS "Entry lib",
04         ENTRY_ACTIVATION AS "Activation"
05    FROM QSYS2.BINDING_DIRECTORY_INFO 
06   WHERE ENTRY = 'SRVPGM1' 
07     AND ENTRY_TYPE = '*SRVPGM'

Lines 6 and 7: The Where clause shows I am looking for only entries that are Service Programs and are called SRVPGM1.

The results are:

Bnd lib    Bnd dir  Entry lib  Activation
---------  -------  ---------  ----------
MYLIB      TEST     *LIBL      *DEFER
MYTEST     TEST     *LIBL      *DEFER
PRODLIB    PROD     *LIBL      *DEFER
PRODLIB2   PROD     *LIBL      <NULL>

I will be using BINDING_DIRECTORY_INFO frequently as it provides the answer to what I wanted to know very easily.
