# SYSCS_UTIL.SYSCS_IMPORT_DATA system procedure

The `SYSCS_UTIL.SYSCS_IMPORT_DATA` system procedure imports data to a subset of columns in a table. You choose the subset of columns by specifying insert columns. This procedure is also used to import a subset of column data from a file by specifying column indexes.

#### Syntax

    SYSCS_UTIL.SYSCS_IMPORT_DATA (IN SCHEMANAME VARCHAR(128),
    IN TABLENAME VARCHAR(128), IN INSERTCOLUMNS VARCHAR(32672),
    IN COLUMNINDEXES VARCHAR(32672), IN FILENAME VARCHAR(32672),
    IN COLUMNDELIMITER CHAR(1), IN CHARACTERDELIMITER CHAR(1),
    IN CODESET VARCHAR(128), IN REPLACE SMALLINT)

No result is returned from the procedure.

SCHEMANAME
  An input argument of type VARCHAR(128) that specifies the schema of the table. Passing a NULL value will use the default schema name.
TABLENAME
  An input argument of type VARCHAR (128) that specifies the table name of the table into which the data is to be imported. This table cannot be a system table or a declared temporary table. Passing a null will result in an error.
INSERTCOLUMNS
  An input argument of type VARCHAR (32762) that specifies the column names (separated by commas) of the table into which the data is to be imported. Passing a NULL value will import the data into all of the columns of the table.
COLUMNINDEXES
  An input argument of type VARCHAR (32762) that specifies the indexes (numbered from 1 and separated by commas) of the input data fields to be imported. Passing a NULL value will use all of the input data fields in the file.
FILENAME
  An input argument of type VARCHAR(32672) that specifies the file that contains the data to be imported. If you do not specify a path, the current working directory is used. Passing a NULL value 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 input file. The name of the code set should be one of the Java-supported character encodings. Data is converted from the specified code set to the database code set (utf-8). Passing a NULL value will interpret the data file in the same code set as the JVM in which it is being executed.
REPLACE
  A input argument of type SMALLINT. A non-zero value will run in REPLACE mode, while a value of zero will run in INSERT mode. REPLACE mode deletes all existing data from the table by truncating the data object, and inserts the imported data. The table definition and the index definitions are not changed. You can only use the REPLACE mode if the table exists. INSERT mode adds the imported data to the table without changing the existing table data. Passing a NULL will result in an error.

If you create a schema, table, or column name as a non-delimited identifier, you must pass the name to the import 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 import 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 Java DB Tools and Utilities Guide.

#### Example

The following example imports some of the data fields from a delimited data file called `data.del` into the `STAFF` table:

    CALL SYSCS_UTIL.SYSCS_IMPORT_DATA
        (NULL, 'STAFF', null, '1,3,4', 'data.del', null, null, null,0)
