SQL catalog reporting and querying
To review the current contents of the SQL catalog you can query the catalog directly or you can use CCACATREPT, the SQL catalog reporting utility. This topic describes CCACATREPT and the queriable views of the SQL catalog.
SQL catalog reporting with CCACATREPT
The CCACATREPT subsystem is a reporting mechanism for data in the CCACAT SQL catalog file. CCACATREPT is a menu-driven utility that produces both online and printed output. With CCACATREPT you can produce a report that provides information about all SQL objects defined in the SQL catalog.
Catalog administrators can compare the CCACATREPT output to the Model 204 file data to determine the updates they need to make to the SQL catalog to obtain consistency with the file. They can modify the report's generated DDL and use it to repopulate the SQL catalog. SQL application programmers and SQL users can use the output to verify valid table, view, column names and column attributes.
This section describes the CCACATREPT menu and provides examples of each of the output formats. CCACATREPT produces the following types of online and printed output:
- File of valid DDL syntax, which you can use to rebuild the catalog
- Fixed format report of a table or view
- Privilege report by table or view name
- Privilege report by user
As an Application Subsystem utility, CCACATREPT is subject to typical Application Subsystem security, as described in System requirements for Application Subsystems. This is the case whether you are accessing CCACATREPT directly from your Model 204 command line as described on this page, or whether you are accessing from the RKTools main menu or the RKWeb interface. RKWeb uses Janus Web Legacy Support to serve facsimiles of the screens described on this page.
Logging in
Before you can log in to CCACATREPT, the CCACATREPT subsystem must already have been started with the Model 204 START SUBSYSTEM command. If you access CCACATREPT from the RKWeb interface, this command is probably already issued as part of the recommended set up for RKWeb.
To log in to CCACATREPT, at your Model 204 Online prompt enter CCACATREPT
and press Enter.
The CCACATREPT Main Menu is displayed.
CCACATREPT Main Menu
The Main Menu of CCACATREPT in the following figure displays the four output formats, their input parameters, and their output destination options.
Using the CCACATREPT panel
After you make final panel field selections and generate a report, CCACATREPT redisplays the panel with those selections.
You can enter an asterisk (*) in an input area to select all the items of a particular category.
The command line (===>) is at the bottom of the panel. Use the command line to enter commands in lieu of PF keys. The minimum abbreviation for a command is generally the first three characters, for example, REF
for REFresh. The minimum abbreviation appears in capital letters in the PF key display area.
The PF keys of the CCACATREPT main menu are described in the following table. In the RKWeb display, comparable buttons replace the PF keys.
Key | Explanation |
---|---|
PF1 = HELp |
You can access either general help information for the panel or additional individual panel field help information. To access general help information for this panel: To access individual panel field help information: |
PF2 = REFresh |
Refresh the screen, and do not process the current data on the screen. The refreshed screen appears as it does when you first entered the panel. |
PF3 = QUIt | Exit from CCACATREPT. Entries are not saved when you use PF3. |
Selection field
Using the Selection field you can generate output from any of the four reports numbered one through four on the menu. Enter an integer from 1 through 4, corresponding to the reports numbered on the menu. The report number you choose determines the input parameter fields. Your must supply one of the values that are listed below the Selection field. The report input parameter fields are followed by a specification in parentheses of the reports for which a value is required.
If you supply a value for a report that does not require it, you receive an error message asking you to remove your incorrect value.
Schema Name field
You must specify an entry in this field if you entered 1, 2, or 3 in the Selection field. Enter the name of a specific schema or enter an asterisk (*) for all schemas.
If your Selection field entry requires an entry for this field and you do not enter a value, by default CCACATREPT outputs all schemas.
Authorization ID field
You must specify an entry in this field if you entered 1 or 2 in the Selection field. Enter the name of a specific authorization ID or enter an asterisk (*) for all authorization IDs.
If your Selection field entry requires an entry for this field and you do not enter a value, by default CCACATREPT outputs all authorization IDs.
Table/View Name field
You must specify an entry in this field if you entered 1, 2, or 3 in the Selection field. Enter the name of a specific table or view to be reported or enter an asterisk (*) for all tables and views.
If your Selection field entry requires an entry for this field and you do not enter a value, by default CCACATREPT outputs all tables and views.
DDL Statement Type(s) field
You must specify an entry in this field if you entered 1 in the Selection field. The output from Selection 1 is standard SQL DDL generated from the Model 204 SQL catalog. In the DDL Statement Type(s) field, you identify the DDL statement types to be generated.
Select one or more of the following identifiers:
Identifier | Statement generated |
---|---|
T | CREATE TABLE |
V | CREATE VIEW |
G | GRANT |
T, V, or G | CREATE SCHEMA or SET SCHEMA CREATE TABLE, CREATE VIEW, and GRANT |
If your Selection field entry requires an entry for this field and you do not enter a value, by default CCACATREPT outputs all the DDL.
Grantee field
You must specify an entry in this field if you entered 4 in the Selection field. Enter the SQL identifier of a specific grantee to be reported or enter an asterisk (*) for all grantees. Privileges granted to PUBLIC are always reported.
If your Selection field entry requires an entry for this field and you do not enter a value, by default CCACATREPT outputs privileges for all grantees.
"USE" Command Arg
Use this field to route output to a destination other than to the terminal. The character string you enter in this field becomes the Model 204 USE command argument that identifies the output destination device.
You can enter any USE command argument that is valid in your operating environment, for example, PRINTER FOO or $PRINT *.
You can route your output to a file. Either dynamically allocate or have your system manager define or allocate an output file prior to your using it from CCACATREPT. For best results under z/OS (and comparably for VM and VSE), make sure that the following are specified in the DD statement or ALLOCATE command for the output file (data set):
- DD name begins with OUT.
- DISP=MOD, if you intend to generate multiple reports before processing the output file
- RECFM=FS, to prevent the printing to the file of carriage control characters
- LRECL=80, to facilitate the reading of the file by CVI or other DDL utility
For more information about the USE command, see USE command: Directing output.
Report Selection 1: Generate DDL
The first reporting option on the Main Menu is to generate the SQL DDL from the existing SQL catalog (CCACAT file) data. This DDL is output in valid SQL syntax that you can use to rebuild the catalog. You can also use it to report the existing catalog data in a standard format familiar to SQL users.
Note: Currently the CCACATREPT subsystem does not generate DDL statement delimiters. However, semicolons are required by the CVI utility. You can add delimiters by hand or use another SQL utility that does not require DDL delimiters. The Connect★ for ODBC unsupported utilities, DDLWIN and CLIIVP, are examples of utilities which accept DDL input lines without delimiters.
Specifying report input parameters
The required input parameters are described in the following table.
Required parameter | Enter... |
---|---|
Schema Name | Specific name, or asterisk (*) |
Authorization ID | Specific ID, or asterisk (*) |
Table/View Name | Specific name, or asterisk (*) |
DDL Statement Types | String of identifiers for the DDL statement types to be generated.
Enter one or more of the following options, without commas or spaces: |
Report input parameter examples
The following examples describe how the report input parameters are used.
Example 1
Specifying the parameters in this example produces CREATE SCHEMA, CREATE TABLE, CREATE VIEW, and GRANT DDL statements for all CCACAT objects.
Schema Name = * Authorization ID = * Table/View Name = * DDL Statement Types = tvg
Example 2
Specifying the parameters in this example produces SET SCHEMA and CREATE TABLE DDL statements for all tables with the authorization ID of USERxxx.
Schema Name = * Authorization ID = userxxx Table/View Name = * DDL Statement Types = t
Example 3
Specifying the parameters in this example produces SET SCHEMA, CREATE TABLE, and GRANT DDL statements for the table USERxxx.CLIENTS.
Schema Name = * Authorization ID = userxxx Table/View Name = clients DDL Statement Types = tg
Ordering the DDL output
The format of the DDL generated by this report option is the same as that generated by the TSF.
To set the schema context, CCACATREPT always places the CREATE SCHEMA or SET SCHEMA statement before the rest of the generated DDL. If you plan to process the generated DDL against the SQL catalog, you might have to change CREATE SCHEMA to SET SCHEMA, because issuing CREATE SCHEMA for a schema that already exists is an error.
For more information about creating schemas, changing the default schema context, and SQL DDL statement processing, see Setting the schema and user context.
You must order statements correctly to avoid forward referencing problems when the generated DDL is processed. For example, a view of a view must reference an already created view. The generated DDL sort order follows:
- Schemas in the order that they were originally input into the SQL catalog.
- Within a schema, all base and parent tables in alphanumeric order, followed by all nested tables in alphanumeric order. Privileges (GRANT statements) for each table follow that table.
- Views follow tables. They are in the order that they were originally input into the SQL catalog. GRANT statements for each view follow that view.
- Grants are ordered by privilege, column name, GRANT statement option, and grantee.
Sample of generated DDL
The sample DDL stream in the following figure is generated by the following input parameter specifications:
Schema Name = demo Authorization ID = * Table/View Name = clients DDL Statement Types = tvg
SET SCHEMA DEMO CREATE TABLE CLIENTS ( ADDRESS CHAR(40), AGENT CHAR(20), ANNIV_DATE SYSNAME 'ANNIV DATE' INT, CITY CHAR(20), DATE_OF_BIRTH SYSNAME 'DATE OF BIRTH' INT, DRIVER_ID SYSNAME 'DRIVER ID' INT, FULLNAME CHAR(40) NOT NULL, MARITAL_STATUS SYSNAME 'MARITAL STATUS' CHAR(15), POLICY_NO SYSNAME 'POLICY NO' CHAR(6) NOT NULL, POLICYHOLDER CHAR(40), RECTYPE CHAR(15) NOT NULL, RESTRICTIONS CHAR(255), SEX CHAR(1), STATE CHAR(25), TOTAL_PREMIUM SYSNAME 'TOTAL PREMIUM' INT, ZIP CHAR(9), PID INT NOT NULL PRIMARY KEY SYSTEM) -- GRANT STATEMENTS FOR TABLE: CLIENTS GRANT DELETE ON CLIENTS TO PUBLIC GRANT INSERT ON CLIENTS TO PUBLIC GRANT SELECT ON CLIENTS TO PUBLIC GRANT UPDATE ON CLIENTS TO PUBLIC
Report Selection 2: Formatted Table/View report

Querying the SQL catalog
You can directly query the Model 204 SQL catalog to obtain information about the current catalog definitions. Any authorized SQL user can access (but not update) any of 18 views of the catalog contents. You use a normal SQL query and devise your own report format for information from the catalog views.
The SQL catalog contains a schema named CATALOG that is comprised of the views of the catalog contents. The views are defined by SQL object. For example, the schemas view in CATALOG contains all the schemas in the catalog by name and by authorization ID.
The CATALOG views are listed here and described individually in the rest of this section.
SCHEMAS (or SCHEMATA) TABLES TABLE_COLUMNS COLUMNS (for tables and views) VIEWS TABLE_CONSTRAINTS KEY_COLUMN_USAGE TABLE_PRIVILEGES COLUMN_PRIVILEGES ODBC_TYPES ODBC_SCALES CONST ODBC_COLUMNS ODBC_SPECIAL_COLS ODBC_TABLES ODBC_TABLE_STATS ODBC_KEY_STATS ODBC_STATISTICS
Querying a CATALOG view
Authorized Model 204 SQL users can query any of the CATALOG views like any other SQL object. However, the views display to you only the SQL objects or information that you have the authority to see or that are granted to PUBLIC.
For example, USERXXX issues the following query against the Model 204 demonstration database:
SELECT * FROM CATALOG.TABLES
The result is a display of information about the tables USERXXX has the authority to select or update. The query's output is shown in the following figure. The format of the output depends on your application and is your responsibility.
The CATALOG.TABLES columns (described in TABLES view), ordered from left to right, are:
TABLE_CATALOG, TABLE_SCHEMA, TABLE_NAME, FILE_NAME, TABLE_TYPE, COLUMN_CARDINALITY, PRIMARY_KEY, SYSTEM_KEY, PARENT_TABLE_NAME, TIMESTAMP
This is the default display order, which derives from the order of the columns in the individual CATALOG view definition.

The output in the previous figure is from two schemas: CATALOG and USERXXX. The CATALOG schema contains the 18 views that describe the catalog contents and is granted to PUBLIC. You can limit the output to the tables in schema USERXXX by using the following SELECT statement:
SELECT * FROM CATALOG.TABLES WHERE TABLE_SCHEMA='USERXXX'
You can list specific columns for display instead of using SELECT *. For example, the following statement results in the same display as that in the previous figure:
SELECT TABLE_CATALOG, TABLE_SCHEMA, TABLE_NAME, FILE_NAME, TABLE_TYPE, COLUMN_CARDINALITY, PRIMARY_KEY, SYSTEM_KEY, PARENT_TABLE_NAME, TIMESTAMP FROM CATALOG.TABLES
The output in the previous figure is grouped by schema, because that is how the DDL used to populate the SQL catalog was organized. An unqualified SQL catalog query returns data chronologically in the order in which the SQL objects were defined or updated in the SQL catalog. As new tables are added to which USERXXX is granted access, this convenient grouping is likely to be lost.
You can ensure that your output is appropriately ordered by sorting the rows by column value with the ORDER BY clause. For example, the following statement sorts the query output by table name, as shown in the following figure:
SELECT * FROM CATALOG.TABLES WHERE TABLE_SCHEMA='USERXXX' ORDER BY TABLE_SCHEMA, TABLE_NAME

Rules for CATALOG queries
- A query against a table that does not exist returns an empty result.
- A query against a table that you do not have the authority to access returns an empty result.
- You cannot issue update SQL DML against the CATALOG views.
SCHEMAS view
The following table lists the CATALOG.SCHEMAS view columns and their descriptions. This view contains a row of identifying information for each schema whose authorization ID is your login ID.
SCHEMATA is an alias for SCHEMAS. You can query either SCHEMAS or SCHEMATA.
The top-to-bottom order of the columns in the following table is the left-to-right order of the columns in each row of output you receive from an unqualified SELECT *
query against the view.
