DB2 UDB for z/OS Version 8 Performance Topics - IBM Redbooks

6.3.1 Performance
► Upload the saved data to the host in one of the following formats:
– text (the data is converted from ASCII to EBCDIC before it is stored on the host)
– binary (the data is stored in ASCII)
To upload the data, you can either use your terminal emulator’s file transfer program, or
use FTP.
► Create a DB2 table with the appropriate number of columns and data types (consistent
with the number of cells and the types of data stored in a spreadsheet), either as an
EBCDIC (default option), or an ASCII table.
► Use the LOAD utility with FORMAT DELIMITED specified as follows:
– If the spreadsheet data is uploaded to the host in text format, specify it as shown in
Example 6-3.
Example 6-3 LOAD DATA text format
LOAD DATA INTO TABLE tablename
FORMAT DELIMITED
– If the spreadsheet data is uploaded to the host in binary format, specify it as shown in
Figure 6-4.
Example 6-4 LOAD DATA binary format
LOAD DATA INTO TABLE tablename
FORMAT DELIMITED ASCII
If you want to move the data from DB2 to a spreadsheet, you take the following steps:
► Use the UNLOAD utility with DELIMITED specified as follows:
– If you want the unloaded data to be in EBCDIC format, specify as shown in
Example 6-5. The data and the delimiters are unloaded in EBCDIC. Transmit the data
to the workstation to be used by the spreadsheet in text format.
Example 6-5 UNLOAD DATA in EBCDIC format
UNLOAD DATA FROM TABLE tablename
FORMAT DELIMITED EBCDIC
– If you want the unloaded data to be in ASCII format, specify as shown in Example 6-6.
The data and the delimiters are unloaded in ASCII. Transmit the data to the workstation
to be used by the spreadsheet in binary format.
Example 6-6 UNLOAD DATA in ASCII format
UNLOAD DATA FROM TABLE tablename
FORMAT DELIMITED ASCII
See DB2 UDB for z/OS Version 8 Utility Guide and Reference, SC18-7427, for more
information about this topic.
We have tested loading the data from a workstation system with delimited format into DB2
and UNLOAD from DB2 to the data which is used by spreadsheet. The LOAD and UNLOAD
of internal and external format data have been measured to compare with LOAD and
UNLOAD delimited data.
