Usage
This statement is an extension to the ANSI/ISO standard for SQL. You can use this statement only with DB-Access.
The LOAD statement appends new rows to the table. It does not overwrite existing data. You cannot add a row that has the same key as an existing row.
To use the LOAD statement, you must have Insert privileges for the table where you want to insert data. For information on database-level and table-level privileges, see the GRANT statement.
In a database that uses a nondefault locale, if the GL_DATETIME environment variable has a nondefault setting, the USE_DTENV environment variable must be set to 1 before the LOAD statement can correctly insert localized DATETIME values into a database table, or into a view, or into an object that the CREATE EXTERNAL TABLE statement defined. For more information on the GL_DATETIME, GL_DATE, DBTIME, and USE_DTENV environment variables, refer to the HCL OneDB™ GLS User's Guide.
