  public void putArray(int index, Object value) throws GPUdbException
  
  For string columns with array property, parse the value parameter which may be a String, List\, int\[], Integer\[], long\[], Long\[], float\[], Float\[], double\[], Double\[]. If the value is not of a relevant type, throw an error.
  
  Parameters:

  value - The value to be parsed (based on the given column's type).
  
  Throws:
  
  GPUdbException - if an error occurs during the operation.

  public void putBytes(String name, Object value) throws GPUdbException
  
  For Byte columns, parse the value parameter which may be a ByteBuffer or byte\[]. If the value is not of a relevant type, throw an error.
  
  Parameters:

  Throws:
  
  GPUdbException - if an error occurs during the operation.
- putBytes
  
  public void putBytes(int index, Object value) throws GPUdbException
  
  For Byte columns, parse the value parameter which may be a ByteBuffer or byte\[]. If the value is not of a relevant type, throw an error.
  
  Parameters:
  
  index - The index of the column.
  
  value - The value to be set.
  
  Throws:

- putDateTime
  
  public void putDateTime(String name, Object value) throws GPUdbException
  
  For string columns with date, time, or datetime property, parse the string and convert to the appropriate Kinetica format using the system timezone. If the column is not of a relevant type, set the value without any parsing (so that any string or other typed values can be set using this method without resorting to first check the column's type before calling it). Caveat is that due to string manipulation, this is considerably slower than put(java.lang.String, java.lang.Object). So, use this method only if you know that a non-Kinetica date/time/datetime format is being used.
  
  Parameters:
  
  name - The name of the column.
  
  value - The value to be parsed (based on the given column's type).
  
  Throws:
  
  GPUdbException - if an error occurs during the operation.
- putDateTime
  
  public void putDateTime(String name, Object value, TimeZone timezone) throws GPUdbException
  
  For string columns with date, time, or datetime property, parse the string and convert to the appropriate Kinetica format using the given timezone (system timezone if none given). If the column is not of a relevant type, set the value without any parsing (so that any string or other typed values can be set using this method without resorting to first check the column's type before calling it). Caveat is that due to string manipulation, this is considerably slower than put(java.lang.String, java.lang.Object). So, use this method only if you know that a non-Kinetica date/time/datetime format is being used.
  
  Parameters:
  
  name - The name of the column.
  
  value - The value to be parsed (based on the given column's type).
  
  timezone - Optional parameter specifying the timezone to use for parsing the given value. If null, the system timezone is used.
  
  Throws:
  
  GPUdbException - if an error occurs during the operation.
- putDateTime
  
  public void putDateTime(int index, Object value) throws GPUdbException
  
  For string columns with date, time, or datetime property, parse the string and convert to the appropriate Kinetica format using the system timezone. If the column is not of a relevant type, throw an error. Caveat is that due to string manipulation, this is considerably slower than put(java.lang.String, java.lang.Object). So, use this method only if you know that a non-Kinetica date/time/datetime format is being used.
  
  Parameters:
  
  index - The index of the column.
  
  value - The value to be parsed (based on the given column's type).
  
  Throws:
  
  GPUdbException - if an error occurs during the operation.
- putDateTime
  
  public void putDateTime(int index, Object value, TimeZone timezone) throws GPUdbException
  
  For string columns with date, time, or datetime property, parse the string and convert to the appropriate Kinetica format using the given timezone (system timezone if none given). If the column is not of a relevant type, set the value without any parsing (so that any string or other typed values can be set using this method without resorting to first check the column's type before calling it). Caveat is that due to string manipulation, this is considerably slower than put(java.lang.String, java.lang.Object). So, use this method only if you know that a non-Kinetica date/time/datetime format is being used. The following patterns are accepted for date and datetime columns: 1) yyyy\[-]\[/]\[.]MM\[-]\[/]\[.]dd\[ ]\['T']\[HH:mm\[:ss]\[.S\[S]\[S]\[S]\[S]\[S]]\[ ]\[XXX]\[Z]\[z]\[VV]\[x]] 2) MM\[-]\[/]\[.]dd\[-]\[/]\[.]yyyy\[ ]\['T']\[HH:mm\[:ss]\[.S\[S]\[S]\[S]\[S]\[S]]\[ ]\[XXX]\[Z]\[z]\[VV]\[x]] 3) dd\[-]\[/]\[.]MM\[-]\[/]\[.]yyyy\[ ]\['T']\[HH:mm\[:ss]\[.S\[S]\[S]\[S]\[S]\[S]]\[ ]\[XXX]\[Z]\[z]\[VV]\[x]] The following pattern is accepted by time-type columns: HH:mm\[:ss]\[.S\[S]\[S]\[S]\[S]\[S]]\[ ]\[XXX]\[Z]\[z]\[VV]\[x] In other words, the date component can be any of YMD, MDY, or DMY pattern withh '-', '.', or '/' as the separator. And, the time component must have hours and minutes, but can optionally have seconds, fraction of a second (up to six digits) and some form of a timezone identifier.
  
  Parameters:
  
  index - The index of the column.
  
  value - The value to be parsed (based on the given column's type).
