Storing and Updating Array Objects

Use the methods PreparedStatement.setArray and PreparedStatement.setObject to pass an Array value as an input parameter to a PreparedStatement object.

The following example sets the Array object northEastRegion (created in a previous example) as the second parameter to the PreparedStatement pstmt:

PreparedStatement pstmt = con.prepareStatement(
    "insert into REGIONS (region_name, zips) " + "VALUES (?, ?)");
pstmt.setString(1, "NorthEast");
pstmt.setArray(2, northEastRegion);
pstmt.executeUpdate();

Similarly, use the methods PreparedStatement.updateArray and PreparedStatement.updateObject to update a column in a table with an Array value.

Change: northEastRegion -> aArray
