The following features apply to all SQL adapters.
Simplified statistical functions can now be optimized to SQL for those adapters that support statistical functions.
The SET HOLDATTR command propagates TITLE and DESCRIPTION attributes from a source Master File to a HOLD Master File. This command is now supported for formats SQL_SCRIPT and SAME_DB.
The following request propagates TITLE and DESCRIPTION attributes to a HOLD file generated as format SQL_SCRIPT.
APP HOLD ibisamp SET HOLDATTR=ON TABLE FILE wf_retail_lite SUM BUSINESS_REGION STATE_PROV_CODE_ISO_3166_2 BY BUSINESS_REGION NOPRINT BY STATE_PROV_CODE_ISO_3166_2 NOPRINT WHERE BUSINESS_REGION EQ 'North America' OR 'EMEA' WHERE STATE_PROV_CODE_ISO_3166_2 EQ 'AR' OR 'IA' OR 'KS' OR 'KY' OR 'WY' OR'CT' OR 'MA' OR '04' OR '11' OR '14'OR 'NJ' OR 'NY' OR 'RI' ON TABLE HOLD AS HOLDATT2 FORMAT SQL_SCRIPT END
The generated Master File, holdattr2.mas follows. The TITLE and DESCRIPTION attributes were propagated from the wf_retail_lite Master File.
FILENAME=HOLDATT2, SUFFIX=DATREC , IOTYPE=BINARY, $
SEGMENT=HOLDATTR, SEGTYPE=S0, $
FIELDNAME=BUSINESS_REGION, ALIAS=E01, USAGE=A15V, ACTUAL=A15V, MISSING=ON,
TITLE='Customer,Business,Region', DESCRIPTION='Business Region', $
FIELDNAME=STATE_PROV_CODE_ISO_3166_2, ALIAS=E02, USAGE=A5V, ACTUAL=A5V, MISSING=ON,
TITLE='Customer,State,Province,ISO-3166-2,Code', DESCRIPTION='The ISO-3166-2 Code for the State or Province', $
FIELDNAME=NULLFLAG, ALIAS=__NULLFLAG__, USAGE=A2, ACTUAL=A2B, ACCESS_PROPERTY=(INTERNAL), $More explanation has been added to messages that result from a rejected outer join request.

The following features apply to the Adapter for Db2.
On FOCUS for Distributed Systems, you can specify the host name, port and database name instead of a DSN when configuring a connection to Db2.

The following features apply to the Adapter for Oracle.
The Adapter for Oracle now has support for Version 18c on distributed systems.
On FOCUS for Distributed Systems, temporal queries against Oracle System-Versioned tables have been implemented by introducing fields with TEMPORAL_PROPERTY SYSTEMTIME. Such a field is added by editing the synonym for the table. For example:
DEFINE FIELD1/HYYMDm WITH REALFLD TEMPORAL_PROPERTY SYSTEMTIME = ;$
The following are requirements for the field with TEMPORAL_PROPERTY SYSTEMTIME.
Fields with TEMPORAL_PROPERTY=SYSTEMTIME can only be used in a single WHERE test of one of the following two types.
WHERE field EQ expression
This type of WHERE test translates to an ORACLE AS OF TIMESTAMP clause.
WHERE field FROM expression1 TO expression2
This type of WHERE test translates to a VERSIONS BETWEEN TIMESTAMP clause.
where:
Must be date-time expressions or constants. When used in a FROM-TO expression, the constants DT('0001-01-01') and DT('9999-12-31') represent the oldest and most recent applicable timestamps. They translate to the ORACLE keywords MINVALUE and MAXVALUE.

The following features apply to the adapters for sequential and indexed files.
When you create a synonym for a delimited file, you can indicate that a header row exists that provides column names. Sometimes, delimited files have other rows above the header row. These rows may be blank or may contain general heading information that do not provide attributes that should be included in the synonym. You can add the SKIP_ROWS=n attribute in the Access File to indicate that these rows should be ignored.
The following is a delimited file named SKIP2 that has two heading rows that should be ignored above the header row that contains the column titles.
"Heading Line 1" "Heading Line 2" "Category","Product","Dollar Sales","Unit Sales" "Coffee","Capuccino",2401556,190880 "Coffee","Espresso",3906243,308986 "Coffee","Latte",11000388,882849 "Food","Biscotti",5387773,430369 "Food","Croissant",7758857,630753 "Food","Scone",4216114,333414 "Gifts","Coffee Grinder",2436215,193616 "Gifts","Coffee Pot",2449585,190695 "Gifts","Mug",4522521,360570 "Gifts","Thermos",2385829,190081
The following is the Master File for the SKIP2 data source.
FILENAME=SKIP2 , SUFFIX=DFIX , $
SEGMENT=SKIP2, SEGTYPE=S2, $
FIELDNAME=CATEGORY, ALIAS=E01, USAGE=A11, ACTUAL=A11, $
FIELDNAME=PRODUCT, ALIAS=E02, USAGE=A16, ACTUAL=A16, $
FIELDNAME=DOLLARS, ALIAS=E03, USAGE=I08, ACTUAL=A08, $
FIELDNAME=UNITS, ALIAS=E04, USAGE=I08, ACTUAL=A08, $ The following is the Access File for the SKIP2 data source, indicating that the first two rows should be ignored.
SEGNAME=SKIP2, DELIMITER=',', ENCLOSURE=", HEADER=YES, SKIP_ROWS=2, CDN=COMMAS_DOT, $
The following request prints all of the fields in the SKIP2 data source.
TABLE FILE SKIP2 PRINT * ON TABLE SET PAGE NOLEAD END
The output is:
CATEGORY PRODUCT DOLLARS UNITS -------- ------- ------- ----- Coffee Capuccino 2401556 190880 Coffee Espresso 3906243 308986 Coffee Latte 11000388 882849 Food Biscotti 5387773 430369 Food Croissant 7758857 630753 Food Scone 4216114 333414 Gifts Coffee Grinder 2436215 193616 Gifts Coffee Pot 2449585 190695 Gifts Mug 4522521 360570 Gifts Thermos 2385829 190081
