As a first step, you can create a target table to store the file system information rows in.

Create the target table manually or by using the CreateFsysInfoTable macro:

exec createfsysinfotable('Call_Logs','showbtrgttablemedium','perm','y',
'showblocks','m', 'TD_Map1');

The following is the definition of the target table for M display option when creating the target table for storing the file system information for SHOWBLOCKS:

show table Call_Logs.showbtrgttablemedium;
CREATE SET TABLE Call_Logs.showbtrgttablemedium ,FALLBACK ,
	NO BEFORE JOURNAL,	
	NO AFTER JOURNAL,
	CHECKSUM = DEFAULT,
	DEFAULT MERGEBLOCKRATIO
	(
	TheDate DATE FORMAT 'YY/MM/DD',
	TheTime TIME(6),
	DataBaseName VARCHAR(128) CHARACTER SET UNICODE NOT CASESPECIFIC 			NOT NULL,
	TableName VARCHAR(128) CHARACTER SET UNICODE NOT CASESPECIFIC NOT 		NULL,
	TableID BYTE(6),
	TableIDTAI INTEGER,
	CompressionMethod CHAR(8) CHARACTER SET LATIN NOT CASESPECIFIC,
	CompressionState VARCHAR(2) CHARACTER SET LATIN NOT CASESPECIFIC,
	EstCompRatio DECIMAL(5,2),
	EstPctOfUncompDBs DECIMAL(5,2),
	PctDBsIn1to8 BYTEINT,
	PctDBsIn9to24 BYTEINT,
	PctDBsIn25to64 BYTEINT,
	PctDBsIn65to120 BYTEINT,
	PctDBsIn121to168 BYTEINT,
	PctDBsIn169to216 BYTEINT,
	PctDBsIn217to256 BYTEINT,
	PctDBsIn257to360 BYTEINT,
	PctDBsIn361to456 BYTEINT,
	PctDBsIn457to512 BYTEINT,
	PctDBsIn513to760 BYTEINT,
	PctDBsIn761to1024 BYTEINT,
	PctDBsIn1025to1304 BYTEINT,
	PctDBsIn1305to1632 BYTEINT,
	PctDBsIn1633to2048 BYTEINT,
	MinDBSize INTEGER,
	AvgDBSize INTEGER,
	MaxDBSize INTEGER,
	TotalNumDBs BIGINT,
	LrgCyls BIGINT,
	SmlCyls BIGINT)
	MapName VARCHAR(128) CHARACTER SET UNICODE NOT CASESPECIFIC NOT NULL
PRIMARY INDEX (TheDate, TheTime, TableID ,TableIDTAI ,CompressionState);
BTEQ -- Enter your SQL request or BTEQ command:

The next example shows the BTEQ output from running PopulateFsysInfoTable macro with the M display option, and empty strings for target_database_name and target_table_name to force the output to display on screen.

The column titles names of the output change when redirected to the screen instead of using the target table to store the output. For example, the column name is “PctDBsIn1to8” in the target table and the corresponding column is “% Of DBs In 1 to 8” when the output is redirected to the screen.

The warning that is returned after PopulateFsysInfoTable macro is expected behavior when the output is displayed to the screen.

The BTEQ .foldline and .sidetitles commands have been used to cause the column titles of the returned data set to be displayed on the side, and the corresponding values of those columns to be shown beside the column titles. This example shows two rows of output. The first column of each row is the Date column.
The following PopulateFsysInfoTable() call example redirects the output/result to the screen (empty strings specified for database and table names). If inserting the output/result to a specific table, ensure the table was created with the CreateFsysInfoTable() macro and that the same /display_opt is specified in both the PopulateFsysInfoTable and CreateFsysInfoTable macro calls.
exec populatefsysinfotable('Call_Logs', 'Daily_Log','showblocks','m','','');
