SYSCS_UTIL.EXPORT_TABLE

Export all data from a table to an operating system file.

For security concerns, and to avoid accidental file damage, this EXPORT procedure does not export data into an existing file. You must specify a filename in the EXPORT procedure that does not exist. When you run the procedure the file is created and the data is exported into the new file.

The data is exported using a delimited file format. For example, you can use this command to export table data as comma-separated values (a CSV file).

Syntax

SYSCS_UTIL.EXPORT_TABLE (IN SCHEMANAME  VARCHAR(128),
IN TABLENAME VARCHAR(128), IN FILENAME VARCHAR(32672),
IN COLUMNDELIMITER CHAR(1), IN CHARACTERDELIMITER CHAR(1),
IN CODESET VARCHAR(128)) 

No result is returned from the procedure.

SCHEMANAME
An input argument of type VARCHAR(128) that specifies the schema name of the table. Passing a NULL value will use the default schema name.
TABLENAME
An input argument of type VARCHAR(128) that specifies the name of the table/view from which the data is to be exported. Passing a null will result in an error.
FILENAME
Specifies the name of a new file to which the data is to be exported. If the path is omitted, the current working directory is used. If the name of a file that already exists is specified, the export procedure returns an error. The specified location of the file should refer to the server-side location if you are using the Network Server. Specifying a NULL value results in an error. The FILENAME parameter takes an input argument that is a VARCHAR (32672) data type.
COLUMNDELIMITER
An input argument of type CHAR(1) that specifies a column delimiter. The specified character is used in place of a comma to signal the end of a column. Passing a NULL value will use the default value; the default value is a comma (,).
CHARACTERDELIMITER
An input argument of type CHAR(1) that specifies a character delimiter. The specified character is used in place of double quotation marks to enclose a character string. Passing a NULL value will use the default value; the default value is a double quotation mark (").
CODESET
An input argument of type VARCHAR(128) that specifies the code set of the data in the exported file. The name of the code set should be one of the Java-supported character encodings. Data is converted from the database code set to the specified code set before writing to the file. Passing a NULL value will write the data in the same code set as the node in which it is being executed.
If you create a schema or table name as a non-delimited identifier, you must pass the name to the export procedure using all uppercase characters. If you created a schema, table, or column name as a delimited identifier, you must pass the name to the export procedure using the same case that was used when it was created.

Example

The following example shows how to export information from the STAFF table in a SAMPLE database to the myfile.del file.

CALL SYSCS_UTIL.EXPORT_TABLE (null, 'STAFF', 'myfile.del', null, null, null);
