SYSCS_UTIL.SYSCS_EXPORT_TABLE system procedure

The SYSCS_UTIL.SYSCS_EXPORT_TABLE system procedure exports all of the data from a table to an operating system file in a delimited data file format.

Syntax

SYSCS_UTIL.SYSCS_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

An input argument of type VARCHAR(32672) that specifies the name of the file to which data is to be exported. If the complete path to the file is not specified, the export procedure uses the current directory and the default drive as the destination. If the name of a file that already exists is specified, the export procedure overwrites the contents of the file; it does not append the information. Passing a null will result in an error.

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 JVM 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.

Usage

For additional information on using this procedure see the section "Using the bulk import and export procedures" in the Derby Tools and Utilities Guide.

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.SYSCS_EXPORT_TABLE (null, 'STAFF', 'myfile.del', null, null, null);
