The following figure illustrates the procedure for standardizing the space characters in existing data.

Figure 13-95 Procedure for standardizing space characters in existing data

Explanation

To standardize the space characters in existing data, use the database reorganization utility (pdrorg command) to reorganize the table. Specify spacelvl=1 in the option statement of the pdrorg command.

For details on reorganizing a table, see 13.2 Reorganizing a table and 13.3 Reorganizing a table (examples).

The following figure illustrates the procedure for standardizing the space characters in new data.

Figure 13-96 Procedure for standardizing space characters in new data

Explanation

To standardize the space characters in new data, specify spacelvl=1 in the option statement when the data is loaded with the database load utility (pdload command). If the spacelvl operand in the option statement is omitted, the value specified in the pd_space_level operand in the system common definition will be assumed.

For details on loading data, see the manual HiRDB Version 9 Command Reference.

The following figure illustrates the procedure for standardizing the space characters when table data is migrated to another system.

Figure 13-97 Procedure for standardizing space characters when table data is migrated to another system

Explanation

For table data migrated to another system, specify spacelvl=1 in the option statement of the database load utility (pdload command) when the data is loaded at the migration destination system.

For details on migrating table data to another system, see 12.1 Migrating a table to another HiRDB system.

The following figure illustrates the procedure for converting space characters when data unloaded with the -W option specified is used by a UAP (in other words, when this UAP performs comparison processing). In this case, the space characters in the table must already be standardized.

Figure 13-98 Using data unloaded with the -W option specified in a UAP

Explanation

• When the data is unloaded, specify spacelvl=3 in the option statement of the database reorganization utility (pdrorg command). Each double-byte space in the national character data is converted into two single-byte spaces.
• The comparison processing of national character data by the UAP is carried out in units of single-byte spaces.
