# SYSCS_UTIL.SYSCS_EXPORT_QUERY system procedure

The `SYSCS_UTIL.SYSCS_EXPORT_QUERY` system procedure exports the results of a SELECT statement 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.

Derby issues a COMMIT or a ROLLBACK statement after each import and export procedure is run (a COMMIT if the procedure completes successfully, a ROLLBACK if it fails). For this reason, you should issue either a COMMIT or ROLLBACK statement to complete all transactions and release all table-level locks before you invoke an import or export procedure.

For more information on using this procedure, see the section "Importing and exporting data" in the Derby Server and Administration Guide.

## Syntax

    SYSCS_UTIL.SYSCS_EXPORT_QUERY(IN SELECTSTATEMENT VARCHAR(32672),
    IN FILENAME VARCHAR(32672), IN COLUMNDELIMITER CHAR(1),
    IN CHARACTERDELIMITER CHAR(1), IN CODESET VARCHAR(128))

No result is returned from the procedure.

SELECTSTATEMENT
  An input argument of type VARCHAR(32672) that specifies the select statement (query) that will return the data to be exported. Passing a NULL value 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 JVM in which it is being executed.

## Execute privileges

If authentication and SQL authorization are both enabled, only the database owner has execute privileges on this procedure by default. See "Configuring user authentication" and "Configuring user authorization" in the Derby Security Guide for more information. The database owner can grant access to other users. The user must also have SELECT privileges on the table.

## Example

The following example shows how to export the information about employees in Department 20 from the STAFF table in the SAMPLE database to the `myfile.del` file.

    CALL SYSCS_UTIL.SYSCS_EXPORT_QUERY('select * from staff where dept =20',
        'c:/output/awards.del', null, null, null);
