Import and export overview

•
To remove specific rows from a table, use the
DELETE
statement.
•
To change existing rows in a table, you can also use the
UPDATE
statement.
From DBISQL you can export data to another database in a variety of formats,
or produce a text file as output. See the next section for a list of formats and
how to select them. You can also redirect the output of any command.
Input and output data formats
The
LOAD TABLE
statement imports text files with one row per line. Both
ASCII and binary input files are supported, with either fixed-length fields or
variable-length fields ended by a delimiter.
The
INSERT
statement moves data into an Adaptive Server IQ table either from
a specified set of values, or directly from tables.
Interactive SQL supports the following output file formats:
File Format
