The setBindColType() methods

public void setBindColType(int colIndex, int sqltype) throws SQLException;
public void setBindColType(int colIndex, int sqltype, int scale)
   throws SQLException;
public void setBindColType(int colIndex, int sqltype, String name)
   throws SQLException;

The first overloaded method allows applications to specify the output type to be java.sql.DECIMAL or java.sql.NUMERIC; the scale parameter specifies the number of digits to the right of the decimal point. The second overloaded method allows applications to specify the output type to be java.sql.STRUCT, java.sql.ARRAY, java.sql.DISTINCT, or java.sql.JAVA_OBJECT by assigning one of these values to the name parameter.
